Alternatives & Comparisons · Sierra Alternatives 2026

Quick Summary

Short answer: Sierra is a $15.8 billion enterprise AI agent platform with quote-only outcome pricing, no self-serve option, and implementation timelines of 3 to 7 months. For teams that need AI customer service without the enterprise complexity, Fin (Intercom) is the strongest choice for proven per-resolution pricing, while Zappiq AI is the most practical option for website lead capture and qualification without an enterprise contract.

  • Zappiq AI is the best Sierra alternative for teams that primarily need website visitor qualification and lead capture without enterprise pricing or complex setup.
  • Fin (Intercom) is the strongest choice for teams that want proven out-of-the-box AI resolution with per-resolution pricing at $0.99 and a 14-day trial.
  • Decagon is worth evaluating for enterprises that need precise workflow control with Agent Operating Procedures and a lower entry price than Sierra.
  • Ada is the volume-deflection veteran with a reported median contract of $73,500 annually, roughly half Sierra's reported entry point.
  • Salesforce Agentforce is the natural fit for teams already in the Salesforce ecosystem, with usage-based Flex Credits pricing.
  • Zendesk AI and Gorgias are options for teams already on those platforms that want native AI without a separate vendor.
  • Forethought, Cognigy, Kore.ai, Replicant, and Tidio fill specific gaps for helpdesk intelligence, contact center orchestration, regulated industries, voice-first support, and accessible SMB chat.

What Sierra Actually Is (And Why Teams Look Elsewhere)

Sierra earned its place as one of the most prominent enterprise AI agent platforms in the market. Co-founded in 2023 by Bret Taylor, a former Salesforce co-CEO and OpenAI board chair, and Clay Bavor, an 18-year Google veteran, the company closed a $950 million Series E at a $15.8 billion valuation in May 2026 and reports $150 million or more in ARR. Its agents handle customer service, account management, and post-purchase workflows across voice, chat, and email in 59 languages, for customers including ADT, SiriusXM, Sonos, Cigna, Rocket Mortgage, Santander, and FINRA. Sierra was certified FedRAMP High in June 2026.

The platform's architectural differentiator is its Agent OS, which combines a planner, executor, and validator model architecture with an Agent SDK and Integration Library. Sierra deployed voice natively inside Agent OS, with sub-second response latency and brand voice cloning as central product features. The company published τ-bench, a benchmark that tests agents on realistic customer service tasks, and built Agent OS supervision around the consistency problem the benchmark surfaced.

⚠️

The pricing and access reality: Sierra does not publish pricing. The platform uses an outcome-based model with custom enterprise contracts, reported to start around $150,000 annually. Sierra's own documentation acknowledges blended approaches: some interactions billed per-conversation for routing and greeting, others per-outcome for successful resolutions. Implementation typically runs 3 to 7 months and requires engineering resources, with professional services costs adding $50,000 to $200,000 or more. First-year total cost estimates for Sierra run around $2.4 million to $3.7 million when helpdesk licensing and per-unit charges are included. There is no self-serve signup, no credit card trial, and no way to estimate cost without a sales conversation.

There is also the architectural reality. Sierra and Decagon are standalone AI agent platforms that require a separate helpdesk for human agent workflows. Neither replaces Zendesk, Salesforce, Intercom, or Freshdesk; they sit alongside, handling autonomous AI resolution while the helpdesk handles human ticketing. For teams already running a helpdesk, that means managing two vendors instead of one. For teams that want a unified platform, the alternatives below are the actual starting point.

The market context also matters. Salesforce signed a definitive agreement to acquire Fin (formerly Intercom) for roughly $3.6 billion in June 2026, expected to close in the fourth quarter of Salesforce's fiscal 2027. That consolidation means the category is shifting, and teams evaluating Sierra today are also evaluating where the whole market is heading. Sierra remains independent, which is a genuine advantage for buyers concerned about roadmap uncertainty, but independence also means Sierra must compete against platforms being folded into larger suites with broader distribution.

Where Sierra Users Are Actually Looking in 2026

Sierra users are not all looking for the same replacement. Teams that used Sierra primarily for voice-heavy Fortune 500 consumer brand support are evaluating different options than teams that need website lead capture or B2B SaaS technical support. The important distinction is between replacing the enterprise AI agent function and replacing the specific job Sierra was doing for your team.

For teams that need AI resolution with per-resolution pricing and a proven deployment track record, Fin is the natural comparison. For teams that need precise workflow control with plain-English agent authoring, Decagon covers that job. For teams already in the Salesforce ecosystem, Agentforce is the path of least resistance. For teams that need website lead capture and qualification without the enterprise complexity, that scope is different entirely.

What Sierra Actually Costs vs the Alternatives

Sierra reported entry contract (annual)~$150,000/yr
Sierra first-year total (estimated, including helpdesk)$2.4M to $3.7M

SMB alternative (Zappiq AI)From free, no implementation project

The tools below replace different pieces of what Sierra does. No single product does everything Sierra does for every team, because Sierra itself is being stretched across jobs that range from enterprise voice automation to B2B SaaS technical support. The honest answer is matching your actual use case to the tool built for it.

✅

Before picking a replacement: Decide which job Sierra was doing for your team. If it was capturing and qualifying website visitors, the tools at the top of this list were purpose-built for that. If it was voice-heavy Fortune 500 consumer brand support, you are looking at a different category with different requirements.

1. Zappiq AI: Best for Website Lead Capture Without Enterprise Overhead

Top Pick for SMB Lead Generation

Zappiq AI

zappiqai.com  |  AI lead generation chatbot for small and medium business websites, no implementation partner required

Why teams choose Zappiq AI
  • Live setup in minutes
  • Automatically trains on your website
  • Qualifies leads and tracks ad source
  • No engineering-led deployment
  • No branding on any plan

The comparison between Sierra and Zappiq AI is almost entirely about scope. Sierra is built to orchestrate customer conversations across voice, chat, and email for Fortune 500 consumer brands with millions of customer interactions per month. Zappiq AI is built to do one thing well: turn website visitors into qualified leads and deliver them to your team while the conversation is still relevant.

For an SMB, that narrower scope is the point. You install a script, Zappiq reads your website, and there is a working chatbot answering visitor questions within minutes. There is no enterprise sales engagement, no 3 to 7 month implementation, no TypeScript SDK to learn before the first conversation. The AI trains itself on your content and starts from there. If something needs adjustment, you adjust it. The base state is already functional.

Sierra's setup process requires engineering resources and vendor-led configuration before the platform does anything useful. The Agent SDK is TypeScript-based, and while Agent Studio 2.0 adds no-code capabilities, the platform's culture and operating model still lean toward vendor-guided iteration. For enterprise CX teams with dedicated resources, that is expected. For SMBs that just need a chatbot that answers questions and captures leads, that overhead is the reason they look elsewhere.

The moment a visitor qualifies, Zappiq emails you the full lead: contact details, intent summary, and the complete conversation transcript. That combination of speed and context matters because website visitors who are ready to buy do not stay ready for long. A lead that sits in a shared inbox for three hours is a different lead than one that arrives with context while the conversation is still fresh.

Pricing is structured around conversation volume rather than outcome-based enterprise contracts. The same traffic spike that would trigger a conversation about contract expansion at an enterprise vendor does not change your Zappiq bill. For an SMB running paid traffic, that predictability matters more than it might seem until the first month you run a campaign and watch volume spike.

💡

Integration options: Zappiq connects to Zapier, Make, and n8n, which means a qualified lead can be pushed into your CRM, a Slack channel, or any other tool your team already uses without touching a line of code. Ad attribution is tracked per lead, so you know which campaign or keyword brought a visitor before they became a contact.

Pricing

100 free conversations $27/month — 1,500 conversations $69/month — 5,000 conversations No per-lead fees or surprise overage charges No branding on any plan

Best for: SMBs that need website visitor qualification and lead capture without an enterprise contract, implementation partner, or months-long deployment. Service businesses, agencies, clinics, legal, real estate, home services, and anyone running paid traffic who wants to know exactly what a lead cost them.

2. Fin (Intercom): Best for Proven Per-Resolution AI

Mid-Market Default

Fin (Intercom)

intercom.com  |  AI agent that runs inside Intercom and 8+ other helpdesks with per-resolution pricing

Intercom Fin AI agent and support workspace for customer conversations
Intercom platform screenshot showing Fin AI agent configuration.

Fin is the proven default for teams that want AI resolution without enterprise procurement. The agent runs on 8+ helpdesks, including Intercom's own, and prices at roughly $0.99 per resolution with seats ranging from $29 to $132. Fin claims a 76 percent average resolution rate across 12,000+ customers. A 14-day trial with unlimited outcomes is available, which Sierra does not offer.

The architectural difference from Sierra is significant. Sierra is a standalone platform that sits above your helpdesk and requires separate human agent workflows. Fin lives inside the helpdesk or runs over an existing one. For teams that do not want to manage a separate AI vendor alongside their existing support stack, Fin eliminates that layer. The tradeoff is less control over agent behavior than Sierra's Agent SDK provides.

There is also the acquisition context. Salesforce signed a definitive agreement to acquire Fin in June 2026, expected to close in the fourth quarter of Salesforce's fiscal 2027. If you already live in Salesforce, that helps you. If you do not, it is worth weighing whether you want your support AI to live inside one suite.

Pricing

~$0.99/resolution Seats: $29 to $132 14-day trial available

Best for: Teams that want proven out-of-the-box AI resolution with per-resolution pricing and a trial before committing. Strong for organizations that value predictability and do not need deep custom agent behavior control.

3. Decagon: Best for Precise Workflow Control

Workflow Control

Decagon

decagon.ai  |  Enterprise AI customer service agent platform with Agent Operating Procedures

Decagon AI customer service agent platform showing Agent Operating Procedures and workflow control
Decagon platform screenshot.

Decagon is the sharpest head-to-head comparison to Sierra for enterprises that need precise workflow control. Both are standalone AI agent platforms that front the conversation. Both are sales-led with no public pricing. The difference is how agent behavior is authored and controlled.

Decagon uses Agent Operating Procedures written in plain English, with Git-tracked version control that lets non-technical CX staff edit agent behavior without engineering involvement. Sierra routes changes through its TypeScript-based Agent SDK and release pipelines, with forward-deployed engineers building alongside customers. That fits governance-focused organizations where agent changes go through review and approval. Decagon fits iteration speed, where CX teams can rewrite agent logic weekly without engineering in the loop.

The entry price difference matters. Decagon starts around $95,000 annually, compared to Sierra's reported $150,000 entry point. Decagon also publishes a deflection range topping out at 75% for mature e-commerce deployments, with customers like Notion, Duolingo, Substack, and Rippling. For technical SaaS companies with engineering bandwidth and support volume concentrated in chat and email, Decagon is structurally a better fit than Sierra.

Pricing

~$95,000/yr estimated Per-conversation billing Quote only

Best for: Technical SaaS companies with engineering bandwidth that need precise workflow control and a lower entry price than Sierra. Strong for support operations with chat and email as primary channels.

Need website leads without enterprise sales engagement?

Zappiq AI trains on your site in minutes, qualifies every visitor automatically, and sends you the lead before the conversation goes cold. No demo required. No implementation partner.

4. Ada: Best for Volume Deflection at Scale

Volume Deflection

Ada

ada.cx  |  No-code AI agent platform for high-volume containment and deflection

Ada AI customer service platform for high-volume containment and deflection
Ada platform visual.

Ada is the volume-deflection veteran with a decade of high-volume containment work. The platform is priced on conversation volume with a reported median contract of $73,500 a year, roughly half Sierra's reported entry point. Ada says customers rate its AI 75% satisfaction with 42% faster handling.

The standardized-workflow approach fits high-volume, repetitive load better than deeply custom deployments. For teams that need containment at scale without the enterprise complexity of Sierra or Decagon, Ada covers that job. The tradeoff is less granular control over agent behavior for complex multi-step workflows.

Pricing

~$73,500/yr median Conversation volume pricing Quote only

Best for: Enterprises that need high-volume containment and deflection at a lower entry point than Sierra. Strong for organizations with standardized, repetitive support volume.

5. Salesforce Agentforce: Best for Salesforce Ecosystem

CRM-Native AI

Salesforce Agentforce

salesforce.com  |  AI agent platform for service, sales, and commerce built on top of CRM data

Salesforce Agentforce CRM AI agents preview

Agentforce is the natural fit for teams already deep in the Salesforce ecosystem. Because its agents run where customer records already live, service teams get grounded, personalized answers without extra integration work. Pricing is usage-based at roughly $2 per conversation plus licensing, with a Flex Credits model at $500 per 100,000 credits.

The tradeoff is that Agentforce is reported to offer more limited support for non-Salesforce systems, and Data Cloud is effectively required for full functionality. A 2026 review noted that realistic first-year costs for mid-market teams can push to $150,000 or more. For teams already on Salesforce, the integration case is real. For everyone else, the dependency is a consideration.

Pricing

~$2/conversation + licensing Flex Credits: $500/100K Data Cloud recommended

Best for: Companies already using Salesforce for service that want AI agents grounded in their CRM data. Strong for organizations that value integration with existing Salesforce workflows over standalone capabilities.

6. Zendesk AI: Best for Helpdesk-Native AI

Platform-Native AI

Zendesk AI

zendesk.com  |  AI agents embedded in the Zendesk platform with verified resolution billing

Zendesk AI agent resolution dashboard for helpdesk-native support automation
Zendesk AI platform visual.

Zendesk AI is the natural choice for teams already running Zendesk for support. The platform restructured AI billing in May 2026 into three resolution tiers, so only LLM-verified resolutions are billed. Essential AI features are now included in every Suite plan, while advanced capabilities remain paid add-ons. Agent Copilot for human agents runs about $50 per agent per month.

The tradeoff is that Zendesk's AI is generalist by design, with no vertical specialization and no AOP-style granular workflow control out of the box. For teams that want AI added to a mature support operation without migrating platforms, Zendesk AI is the path of least resistance. For teams that need deep custom agent behavior, Sierra or Decagon are stronger fits.

Pricing

From $55/mo Agent Copilot: ~$50/agent/mo Verified resolution billing

Best for: Teams already running Zendesk that want native AI without adding a separate vendor. Strong for organizations that value platform consolidation over standalone agent capabilities.

7. Gorgias AI Agent: Best for Shopify-Native Ecommerce

Ecommerce Specialist

Gorgias AI Agent

gorgias.com  |  Automation layer inside Gorgias helpdesk for Shopify stores

Gorgias homepage hero.

Gorgias AI Agent is the automation layer inside Gorgias, the helpdesk built for e-commerce. For a Shopify merchant already on Gorgias, it reads order data and handles common questions like order status, shipping, and returns directly in the thread. Around 15,000 brands run on Gorgias.

Pricing is $0.90 per resolved conversation on annual billing or $1.00 on monthly, on top of a Gorgias helpdesk plan starting from $10 a month. The dual-billing structure, where an automated resolution also counts as a helpdesk ticket, can surprise teams. But for Shopify-native brands that want native order data integration, Gorgias covers that job.

Pricing

$0.90 to $1.00/resolution Helpdesk from $10/mo Dual billing applies

Best for: Shopify merchants on Gorgias who want native support automation tied to order data. Strong for ecommerce brands that value platform consolidation and pre-built e-commerce workflows.

forethought">8. Forethought: Best for Helpdesk Intelligence

Ticket Intelligence

Forethought

forethought.ai  |  Ticket intelligence and auto-resolution for existing helpdesks

Forethought customer support AI platform for ticket intelligence and auto-resolution
Forethought platform visual.

Forethought is the strongest alternative for teams that want helpdesk intelligence without replacing their existing support platform. The platform provides ticket triage, auto-resolution, and agent assistance within existing helpdesks, which means teams can add AI capabilities without migrating to a new system.

For teams already on Zendesk, Salesforce, or another helpdesk that want AI triage and auto-resolution layered on top, Forethought covers that job. The tradeoff is that Forethought is not a standalone agent platform in the way Sierra or Decagon are, with narrower scope for custom agent behavior.

Pricing

Quote only Enterprise contracts

Best for: Teams that want ticket intelligence and auto-resolution layered on top of their existing helpdesk without migrating platforms. Strong for organizations that value integration with current support workflows.

9. Cognigy: Best for Contact Center Orchestration

Contact Center AI

Cognigy

cognigy.com  |  Enterprise conversational AI platform as part of the NiCE CXone stack

Cognigy conversational AI platform for contact center orchestration
Cognigy platform visual.

Cognigy is the strongest alternative for enterprises that need contact center orchestration with voice and digital channels. NiCE acquired Cognigy in a deal that closed in September 2025, and it now operates as NiCE Cognigy, the native AI layer of NICE CXone. Bosch, Nestlé, DHL, Lufthansa, Mercedes-Benz, and Toyota are among its customers.

The platform provides tools for building and running agents across voice, chat, and messaging with broad multilingual support and native CXone integration. For teams already on NICE CXone, the consolidation works in your favor. For everyone else, the question is whether the NICE stack is where you want to be.

Pricing

Quote only Enterprise contracts No public rate card

Best for: Large enterprises in banking, healthcare, and government automating contact centers within a NICE CXone environment. Strong for organizations that need voice and digital channels with deep CCaaS integration.

10. Kore.ai: Best for Regulated Industry Compliance

Compliance Leader

Kore.ai

kore.ai  |  Enterprise conversational AI platform for regulated industries

Kore.ai platform visual.

Kore.ai is the strongest alternative for regulated industries that need deep compliance coverage alongside broad conversational AI capabilities. The platform serves over 200 Fortune 2000 customers including PNC Bank, Cisco, Pfizer, Coca-Cola, and Airbus, with particular depth in financial services and healthcare deployments. It covers HIPAA, PCI DSS, SOC 2 Type II, and GDPR compliance with field-level encryption and PII redaction.

Forrester's April 2026 Wave named Kore.ai as a Leader and awarded it the field's highest current-offering score at 4.14, with top marks across ten criteria. For teams in regulated industries that need broad automation across customer experience and employee experience, Kore.ai is the natural fit. The tradeoff is enterprise pricing and implementation timelines.

Pricing

Quote only ~$300,000/yr estimated

Best for: Large enterprises in regulated industries that need broad automation across customer experience and employee experience with the deepest compliance coverage. Strong for organizations with dedicated technical resources.

11. Tidio: Best for Accessible SMB Chat

Accessible AI Chat

Tidio

tidio.com  |  Live chat and AI chatbot platform for small businesses and ecommerce stores

Tidio homepage showing live chat and AI chatbot tools for small businesses and online stores
Tidio platform screenshot.

Tidio is what Sierra looks like when the pricing is public and the setup does not require an enterprise sales engagement. The core job is similar: greet visitors, answer questions, qualify leads, hand the good ones to a human. The execution is designed for someone who does not have an enterprise budget or a technical team.

Tidio's Lyro AI handles customer conversations autonomously with fast setup and a free tier. Plans start from $24.17 per month billed annually. For an SMB that needs live chat with an AI layer at an accessible price point, Tidio covers that job.

Pricing

Free: 50 conversations/mo Paid: from ~$24/mo

Best for: SMBs that need affordable conversational AI without enterprise complexity. Strong for teams that need quick setup and do not require the depth of an enterprise agent platform.

How to Evaluate a Sierra Alternative

✅

Start with the job, not the feature list: The right replacement depends on which specific thing Sierra was doing for your team. Answering that question first saves time on comparisons that were never relevant.

Sierra was used differently by different teams, which is part of why this list does not have one obvious answer. Fortune 500 consumer brands used Sierra for voice-heavy support with brand voice cloning. B2B SaaS companies used it for technical support with complex workflows. Support teams used it for ticket deflection. None of those jobs requires the same replacement.

If your team needs AI resolution with per-resolution pricing and a proven deployment track record, Fin is the natural choice. For enterprises that need precise workflow control with plain-English agent authoring, Decagon covers that job. For organizations already in the Salesforce ecosystem, Agentforce is the path of least resistance. For regulated industries that need deep compliance coverage, Kore.ai is the natural fit.

If your use case is website lead capture and qualification without the enterprise complexity, a focused tool like Zappiq AI covers that job directly. The key difference from Sierra is that Zappiq starts with a working chatbot from day one without requiring an enterprise sales engagement or a 3 to 7 month implementation before anything happens. For an SMB looking for a practical alternative, that simplicity matters a great deal.

For teams that need voice-first support with a mature CCaaS platform, Cognigy and Replicant cover those jobs. For Shopify-native ecommerce brands, Gorgias is the natural fit. For teams already on Zendesk, adding Zendesk AI is worth evaluating before paying for a separate platform.

Migration Checklist: Moving Away from Sierra

An AI agent migration is not complete when the new platform is live. The risky parts are the agent configurations, SDK integrations, and backend connections that your team built around Sierra. Use this checklist before turning the old workflow off.

  1. Document your agent configurations and SDK integrations. Save the agent logic, policies, escalation rules, and any custom TypeScript code before rebuilding them elsewhere.
  2. Record integration and backend system details. Note ownership rules, CRM fields, webhooks, notifications, and any custom integrations that connect to the platform.
  3. Export conversation data. Keep transcripts, contact details, and outcomes in a format your team can search after the migration.
  4. Choose the replacement by job. Use a lead-generation tool for website qualification, a helpdesk-native AI for resolution, or a contact center platform for voice-first support.
  5. Run the new tool in parallel for at least two weeks. Compare answers, resolution rates, lead delivery, routing, and handoffs before removing Sierra.
  6. Cut over and monitor the first month. Review unanswered questions, duplicate conversations, attribution, response time, and every integration that receives a qualified conversation.
💡

Keep the old workflow available during testing. Parallel testing gives your team a way to compare real conversations and catch missing routing or knowledge gaps before it affects customer experience.

Frequently Asked Questions

How much does Sierra cost?

Sierra does not publish pricing. The platform uses an outcome-based model with custom enterprise contracts, reported to start around $150,000 annually. Sierra's own documentation acknowledges blended approaches: some interactions billed per-conversation for routing and greeting, others per-outcome for successful resolutions. Implementation typically runs 3 to 7 months and requires engineering resources.

What is the best Sierra alternative for mid-market teams?

The best alternative depends on the job. Zappiq AI is the most practical option for teams that primarily need website visitor qualification and lead capture without enterprise pricing or complex setup. Fin (Intercom) is the strongest choice for teams that want proven out-of-the-box resolution with per-resolution pricing. Decagon and Ada are worth evaluating for enterprises that need workflow control or high-volume deflection.

Is there a free Sierra alternative?

Zappiq AI offers 100 free conversations to start with no credit card required. Fin (Intercom) offers a 14-day trial. Tidio has a free plan with 50 conversations per month. Most enterprise-focused alternatives do not offer free trials because they require sales engagement and implementation planning.

What is the difference between Sierra and Decagon?

Both are standalone enterprise AI agent platforms that front the conversation. Sierra uses a programmatic Agent SDK with release pipelines and vendor-led implementation. Decagon uses Agent Operating Procedures written in plain English, with per-conversation billing by default. Sierra is voice-first with brand-voice cloning. Decagon is text-first with engineering-led setup.

Why do teams look for Sierra alternatives?

Teams look for Sierra alternatives when quote-only outcome pricing is hard to budget against, when they want to trial a platform self-serve rather than enter a sales-led procurement cycle, when they need a published connector library instead of integration work scoped during implementation, or when the need is narrower than a full platform.

What is the best Sierra alternative for voice-first support?

For voice-first support with a mature CCaaS platform, Cognigy covers that job as part of the NICE CXone stack. Replicant also provides AI-powered voice agents for complex customer service calls. For teams that need voice as part of a broader AI agent platform, Sierra remains strong, but the implementation complexity and pricing are considerations.

The Bottom Line

Sierra built one of the strongest enterprise AI agent platforms in the market, raised $950 million at a $15.8 billion valuation, and earned real results with Fortune 500 customers. The Agent OS architecture, voice-first capabilities, and FedRAMP High certification are genuine strengths. The founders' pedigree and customer roster are as strong as the category has.

For SMBs and mid-market teams, the problem is not the product. It is the access and the scope. Sierra is sold through enterprise sales engagement with no self-serve signup, no public pricing, and implementation timelines of 3 to 7 months that require engineering resources and vendor involvement. For Fortune 500 consumer brands with the budget and the resources, that is a reasonable tradeoff. For teams without either, it is the reason they look elsewhere.

The right replacement depends on which job Sierra was doing for your team. For teams that need proven per-resolution AI with a trial, Fin covers that job. For enterprises that need precise workflow control, Decagon is the natural fit. For organizations already in the Salesforce ecosystem, Agentforce is the path of least resistance. For regulated industries that need deep compliance coverage, Kore.ai is the natural choice.

For SMBs that primarily need website visitors qualified and delivered to a sales team, Zappiq AI covers that job without the enterprise contract, the implementation partner, or the months-long setup. The chatbot reads your site and starts working on day one.

The free trial for Zappiq AI is at zappiqai.com. No credit card needed, no annual contract, no implementation project before your first visitor conversation.
