Ada vs Fin (2026)

Ada and Fin both sell AI agents that resolve customer service conversations end to end, but they answer "how should a team buy this?" with opposite assumptions. The differences are not feature parity. Both run across chat, email, voice and the major messaging channels, both expose APIs and an MCP server, both ship a Playbook/Operator-style improvement loop, and both cite large customer books. The differences sit at the procurement desk and the helpdesk desk, and they decide which team each product is right for.

Pricing is the cleanest place to start. Every Ada engagement begins with a sales call: there is no self-serve signup, no public price list and no free trial, and Vendr's tracked purchase data puts the median contract at $72,000 per year, with annual platform fees typically running from around $100,000 for mid-size deployments to north of $300,000 for the largest, plus separate implementation fees. Fin publishes pricing on the page: $0.99 per resolution, a 50-outcome monthly minimum, and a 14-day free trial with no credit card and unlimited outcomes during the trial. That $0.99 figure is the rate for resolutions and Procedure handoffs; Qualifications are billed at $9.99 each, which is roughly ten times the headline number, and "resolution" includes cases where the customer simply stops replying, so spend can grow with traffic in ways the headline does not predict.

Architecture is the second axis. Ada's ACX Platform is a single-vendor stack that owns the agent definition across chat, voice, email, messaging, in-app and custom channels, with the Reasoning Engine, Conversation Hub, Playbooks and Performance Center bundled under one contract. Fin is built to sit on top of a helpdesk the team already runs (Intercom, Salesforce, HubSpot, Freshworks, Dixa, Front, Zoho, Sprinklr or Gorgias) and resolves the front line while the existing ticketing stays put. If your helpdesk decision is already made, Fin usually wins on switch cost; if it isn't, Ada is the whole stack and the bill is one line instead of three.

Reliability and independence are the third axis. Ada is a 2016 Toronto company with $200M+ raised and a $1.2B Series C in 2021, and named case studies from IPSY, Loop Earplugs, Cebu Pacific and Life360. Its admin-side G2 score sits at 4.6 out of five, but the Trustpilot end-user score on the Ada.support profile is 1.8 out of five, a real gap between the polish of the operator console and what the customer actually experiences in chat. Fin reports a 76% average resolution rate across 12,000+ customers with the top 10% above 85%, but Salesforce signed a definitive agreement on 2026-06-15 to acquire Fin for roughly $3.6 billion, expected to close around Salesforce's fiscal Q4 2027, and neither company has published what changes for teams running Fin on a non-Salesforce helpdesk once the deal closes.
