Sierra
Conversational AI platform for building enterprise customer-service agents across voice, chat, email and ChatGPT.
CustomWhere it improves on Ada
- +Debugs and fixes · PartialGhostwriter diagnoses its own failed simulations and implements the fix; the failure it repairs is agent behaviour, never a defect in your software.Evidence ↗
- +Writes tests · PartialConversation and voice simulations are generated and run on every agent build, and Agent Studio keeps them as a regression suite; these test agent behaviour, not your code.Evidence ↗
- +Multi-agent · YesNamed agents pass work to each other: Explorer analyses conversations and hands a recommendation to Ghostwriter, which implements it.Evidence ↗
Trade-offs against Ada
- −Agent permissions · PartialAutonomy is configured, not fixed: messaging is fully autonomous by default while you declare which steps need human sign-off, and unresolved cases hand off to your care team.Evidence ↗
- −Claude · PartialAnthropic is a named subprocessor for large-language-model serving inside the platform, but Sierra routes each turn itself, so choosing Claude is not something a customer does.Evidence ↗
- −GPT · PartialOpenAI is listed as an AI-services subprocessor with US and EU processing, and Sierra publishes an agent channel inside ChatGPT; the customer does not select the model.Evidence ↗

Fin
Customer service AI agent priced per resolved outcome, deployable on any helpdesk.
$0.99 / outcomeWhere it improves on Ada
- +Multi-agent · PartialTwo agents exist: Fin faces customers, Operator runs operations and tunes Fin. The vendor does not describe agents collaborating on one conversation.Evidence ↗
- +Free tier · Partial14-day trial with unlimited outcomes and no credit card, but no free tier afterwards; the non-Intercom path is contact-sales.Evidence ↗
- +Seat model · PartialNo seat cost on third-party helpdesks, where teammates are unlimited; on Intercom, helpdesk seats are $29/month each on top of outcomes.Evidence ↗
Trade-offs against Ada
- −Open models · NoThe enumerated provider list is OpenAI, Anthropic, Google and Intercom's own models; no open-weight option is offered.Evidence ↗
- −API access · PartialFin Agent API and Data Connectors are publicly documented; the Fin API Platform (Apex, RAG, Retrieval, Reranker) is gated at $250k annual spend.Evidence ↗
32/35 researched criteria · 3 not established - 03
Zendesk AI agents
Customer-service AI agents for messaging, email and voice, billed per automated resolution.
$19 / agent/month, billed annuallyWhere it improves on Ada
- +Multi-agent · PartialAdmins can build many task-scoped custom agents alongside the channel AI agents, but Zendesk does not describe several agents coordinating on one task.Evidence ↗
- +Free tier · Partial14-day self-serve trial with no card; there is no permanent free tier, and startups can apply for a longer free program.Evidence ↗
- +Bring your own key · PartialNo bring-your-own-LLM-key or own-cloud inference. BYOK exists only as encryption-key control in a paid privacy add-on.Evidence ↗
Trade-offs against Ada
- −Claude · PartialClaude is not what powers the agent; it is reachable as an external action in action flows using your own Anthropic key.Evidence ↗
- −Open models · NoEvery generative path the vendor enumerates is a managed hosted API; no open-weight or customer-supplied model is offered.Evidence ↗
- −MCP server · PartialZendesk is an MCP client: AI agents can call tools on external MCP servers from Suite Growth / Support Team upward. No vendor-documented MCP server exposing the AI agents to other agents.Evidence ↗
35/35 researched criteria - 04
IrisAgent
AI support agent that resolves chat, email and phone tickets inside your existing helpdesk.
Where it improves on Ada
- +Multi-agent · PartialOne deployment carries several specialised agents (support, IT help desk, knowledge, ticket automation, QA), but the vendor never documents several agents coordinating on a single conversation.Evidence ↗
- +Open models · YesFine-tuned open-weight models handle the cheapest routing tier on IrisAgent's own infrastructure, and private deployments can run open models inside your boundary.Evidence ↗
- +Model choice · PartialOn the hosted product the vendor routes each query by intent and complexity and states the model choice is not the buyer's; only private deployments let you bring approved models.Evidence ↗
Trade-offs against Ada
- −Claude · NoThe security FAQ enumerates exactly two model options for the hosted product, in-house private models or OpenAI, and never names Anthropic as a model IrisAgent runs.Evidence ↗
- −Audit log · PartialA per-answer trail showing the response served and its source is claimed for enterprise deployments, but logging of administrative configuration changes is never asserted for IrisAgent itself.Evidence ↗
- −Single sign-on · PartialEvery account signs in through Google, Microsoft, Salesforce or Okta OIDC with no local passwords, but the plan comparison lists SSO / SAML as an Enterprise-only row, so SAML federation reads as gated.Evidence ↗
33/35 researched criteria · 2 not established - 05
Crescendo
AI-native CX platform whose agents resolve customer contacts across voice, chat, email and messaging.
From $2.99 per resolution / per resolutionWhere it improves on Ada
- +Done-for-you service · YesCrescendo deploys its own CX team alongside the software and takes escalations through a network of human specialists.Evidence ↗
- +Multi-agent · YesNamed specialised agents (Concierge, Quality, Applied Insights, Optimization, Integration, Simulation, Knowledge, Workforce) run one operation together.Evidence ↗
Trade-offs against Ada
- −Claude · NoThe sub-processor enumeration lists OpenAI, Google Gemini/Vertex AI, Groq and Azure as AI providers; Anthropic appears nowhere.Evidence ↗
- −MCP server · PartialCrescendo calls itself MCP-native for reading live backend systems; it never documents an MCP server another agent could query.Evidence ↗
- −Pooled budget · PartialBuyers hold one contracted conversation volume rather than per-seat balances, and low-CSAT conversations are excluded from it; no allocation or sub-budget controls are described.Evidence ↗
29/35 researched criteria · 6 not established - 06
Decagon
Enterprise AI support agents for chat, voice and email, built from natural-language Agent Operating Procedures.
CustomWhere it improves on Ada
- +Multi-agent · PartialA separate supervisor model reviews responses and Duet iterates on the agent, but the vendor describes a network of specialised models rather than agents coordinating on one task.Evidence ↗
- +In your pipeline · YesAgent versions can be tested inside existing CI/CD practices before release.Evidence ↗
- +Getting out · YesCustomer data can be retrieved or deleted via public APIs at any time, and is deleted irrecoverably after termination; no credit balances to expire.Evidence ↗
Trade-offs against Ada
- −Done-for-you service · NoSoftware the buyer's own CX team builds and iterates on; the vendor positions itself against professional-services delivery.Evidence ↗
- −Agent permissions · PartialGuardrails gate sensitive actions such as identity verification and refunds, and Duet's agent changes are staged for human review before release.Evidence ↗
- −Claude · PartialAnthropic is named as one of the AI providers behind the platform, but the vendor selects models and says most traffic runs on its own.Evidence ↗

How the shortlist is calculated
Comparable first. We consider listings in the same category as Ada and alternatives previously researched for this page.
Requirements first. We prioritise your selected needs, then shared strengths, fewer documented trade-offs, more complete research and finally alphabetical order.
Unknown remains unknown. Missing evidence is never converted into a benefit or a trade-off. Every improvement shown above comes from the same sourced criterion as the listing.
Independent order. Payment does not affect selection or ranking. Paid placements are labelled Advertisement.
