Cast Corporation

Market position

Cast operates in the digital customer success and post-sales automation segment, presenting itself as complementary to, rather than competitive with, CRM and customer success platforms such as Salesforce, HubSpot, Gainsight and Totango. It reports deployments at large enterprise technology vendors and describes delivering more than 200,000 business review presentations per month.

Cast positions itself as distinct from CRMs, customer success platforms and CSM copilots: where copilots assist the internal CSM, Cast's agents face the customer directly, presenting reviews and answering questions for users, decision-makers and accounts that cannot be staffed. It emphasizes day-1 readiness on top of existing systems, per-contact and per-account grounding at runtime across CRM, customer success, support and product data, multilingual presentation, and embedding into a vendor's own application with minimal integration effort.

Technology

AI agents that generate and present business reviews and answer questions using grounded retrieval across CRM, customer success, support and product data, with grounding applied per contact and per account at runtime. The platform integrates with Salesforce, HubSpot, Gainsight and Totango, supports 17 spoken languages, and offers embeddable presentations via a two-line code snippet in web, mobile, portal or dashboard contexts. Two REST surfaces are publicly documented: a read-only Analytics API for campaign engagement summaries, paged engagement events, campaign lists and cross-campaign rollups, and an In-app Delivery API that mints personalized presentation permalinks, accompanied by a cast-inapp-loader.js embeddable launcher and a first-party React example. The company states customer data is not used to train its models, and publishes a first-party llms.txt file (13KB, self-dated 2026-08-11).

Go-to-market

Cast markets directly to customer success, customer experience and post-sales operations leaders at enterprise technology vendors, using a book-a-demo motion on its website supported by named customer testimonials, case studies and interviews. Referenced users include leaders at Ruckus, Everpure (formerly Pure Storage), CDK Global, Cloudera, HPE GreenLake, Intelex, Portworx, Aruba, Source1 Purchasing, Dining Alliance, Buyers Edge Platform, vCom Solutions and Plansight. Adoption is also described as following individuals across employers, with one customer reporting use of Cast at Aruba, HPE and CDK.

Geography

The company is associated with the San Francisco Bay Area, with a Techstars profile listing Berkeley, San Francisco, Burlingame, Sunnyvale, San Carlos, Vallejo, Albany and Oakland, California, and a business listing placing it in San Carlos, CA 94070. Language support spanning 17 spoken languages and references to global customer books indicate international customer deployments.

History

Cast Corporation published its Terms of Use with a last-updated date of October 1, 2020. A Techstars company profile lists the company at cast.app with a founding year of 2019 and a size band of 1-10 employees, and locations across the San Francisco Bay Area including Berkeley, San Francisco, Burlingame, Sunnyvale, San Carlos, Vallejo, Albany and Oakland. An independent third-party API profile published in 2026 lists Cast as backed by Techstars, Array Ventures, Soma Capital, New York Venture Partners and Leonis Capital.

Risks & controversies

The company publishes no machine-readable API specification (no OpenAPI, Swagger, GraphQL SDL, AsyncAPI, JSON Schema or Postman collection on its API host, docs host or GitHub organization), and both documented APIs exist only as HTML prose. As probed on 2026-08-13, cast.app and school.cast.app return 404 for /.well-known/ resources including security.txt, openid-configuration, oauth-authorization-server, oauth-protected-resource, api-catalog, ai-plugin.json, agent-card.json and agent.json, and there is no reachable MCP server or A2A agent card, no status page, deprecation policy, changelog, published rate limits, or SDK on a package registry. The company's own llms.txt states the platform supports open agent protocols including MCP, A2A and ACP, which the third-party profile characterizes as protocols Cast's agents consume rather than endpoints a client can reach. The site's terms state it is not tailored to industry-specific regulations such as HIPAA, FISMA or GLBA.
