AI support agents that resolve tickets inside your own systems
Agents read from and write to Zendesk, Salesforce, Intercom, Stripe, Okta, Duo, Splunk and any other API-connected tool, so tickets that need an action can be closed without a human.
Describe a process conversationally and Brainfish builds, tests, and runs it as a repeatable workflow — reportedly from a draft in about ten minutes to a complex workflow in a couple of hours.
Refund caps, approval thresholds, and policy windows live in the workflow logic rather than the prompt, so the same request is handled identically on every run.
Every step, system touched, and source cited is logged, with SSO/SAML, regional data residency, and a no-training-on-your-data commitment.

AI-first help desk that resolves tickets, not just sorts them
Kay classifies, prioritises and routes incoming tickets, enriches them with customer context, and cuts the manual sorting that eats agent time.
The AI drafts accurate replies or asks follow-up questions, automatically handling repetitive cases and shortening average handle time.
Kay learns from human resolutions, expands its intent coverage and compounds deflection performance over time.
Email, live chat, social and voice land in one shared queue with full customer history, orders and data attached to every ticket.
