Cardinal is an AI platform for precision outbound sales — it markets itself as "revenue agents for high-growth companies" — built for go-to-market teams that want outbound to run as one engine instead of a stack of disconnected tools. Its agents build and refresh account lists from signals, monitor what prospects post and engage with, generate personalized snippets, and orchestrate end-to-end email and LinkedIn plays, while capturing inbound from website visitors, product signups and ad impressions. The company is a Y Combinator Winter 2026 company founded by Devishi Jha and Jianna Liu, based in San Francisco, and names Mintlify, Deepgram, Greptile, Giga and Luminai among its customers. Cardinal moved its primary web presence from trycardinal.ai to trycardinal.com during 2026: https://trycardinal.ai/ now HTTP 301s to https://www.trycardinal.com/ and the former deep pages on the .ai domain (/company, /product) return 404, though the company still runs its customer application, its email and its analytics identity on trycardinal.ai. The product is sold as half-software and half-service ("we wire into your existing stack and build agents around plays that already work for you"), delivered through a customer app at app.trycardinal.ai behind a Stytch login, with a Calendly GTM chat as the only publicly reachable entry point. It reads from and writes back to customer CRMs and says it adds a new integration every two weeks, but names none of them publicly and publishes no outbound API of its own: across four hosts on two domains this pass found no OpenAPI, GraphQL SDL, AsyncAPI, MCP server, agent card, webhook catalog, SDK, CLI, developer portal or documentation site. docs.trycardinal.ai does not resolve in DNS, api.trycardinal.ai is a dangling custom domain whose Render origin answers x-render-routing: no-server, and every /api/* path on the customer app returns HTTP 401 {"error":"Unauthorized"}.
