Cast Corporation

Cast Corporation (Cast.app) is an AI-agent platform that automates customer success and post-sales revenue operations for B2B SaaS and technology companies. Its autonomous "digital CSM" agents deliver personalized business reviews, grounded answers, onboarding, usage adoption, churn reduction, renewal influence, and referral workflows across email, in-app, and chat in 17 languages. Cast positions itself as an autopilot layer over an existing stack, connecting natively to 60+ systems including Salesforce, HubSpot, Gainsight, Totango, and data warehouses, with customers such as Pure Storage, HPE, and Aruba Networks. Backed by Techstars, Array Ventures, Soma Capital, New York Venture Partners, Leonis Capital, and Comcast NBCUniversal LiftLabs. Cast publishes two documented REST surfaces: a Cast Analytics API for exporting campaign engagement events and summaries, and an In-app Delivery API plus embeddable loader for minting personalized presentation permalinks inside a customer's own web app. Both are documented in prose only — Cast publishes no OpenAPI, AsyncAPI, GraphQL SDL, or Postman collection.

Cast Corporation publishes 2 APIs on the APIs.io network. Tagged areas include Company, Customer Success, Artificial Intelligence, AI Agents, and Revenue Operations.

The Cast Corporation catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Cast Corporation’s developer surface includes documentation, API reference, getting-started guide, support, pricing, signup flow, engineering blog, and 22 more developer resources.
