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 is listed with 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.

Regulatory Posture applies to this provider. Its tags matched the
Horizontal (data, software, accessibility, platform) regime, so
Regulatory Posture carries 15 points of the composite.
If this regime is wrong for your business, say so on your
provider repo — the
applicability map is public and we will correct it.
Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for
this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero:
never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and
several others — scorable at all.
The six quality facets above are damped to 85 points between them,
because the conditional facet above carries the other
15. That is why each facet's contribution is shown against a damped
maximum: raising a quality facet moves the composite by 85% of its nominal
weight, not 100%. The full arithmetic is at apis.io/rating/.
