Clozd

Clozd is a Lehi, Utah based decision-intelligence and win-loss analysis platform that collects structured buyer feedback — through human-led live interviews, AI-assisted Flex interviews, and autonomous Flow interviews — and turns it into decision drivers, competitor sentiment, win rates, and verbatim buyer quotes for sales, marketing, product, and customer-success teams. The platform integrates with Salesforce, HubSpot, Microsoft Dynamics, Gong, Slack, Calendly, Outlook, and Gmail, and exposes two public programmatic surfaces: the versioned Clozd Data API (v1/v2/v3) documented with OpenAPI 3.0.3 and Swagger UI at app.clozd.com for importing deals and participants and exporting programs, deals, touchpoints, responses, transcripts, and competitors; and a hosted, OAuth 2.0 protected Model Context Protocol server at mcp.clozd.com that gives Claude, ChatGPT, Cursor, Copilot, Windsurf, Antigravity, and Gemini CLI direct tool access to the same win-loss data.

Clozd publishes 3 APIs on the APIs.io network: Data API v3.0, Data API v2.0, and Data API v1.0. Tagged areas include win-loss-analysis, customer-feedback, decision-intelligence, sales-intelligence, and market-research.

Clozd’s developer surface includes documentation, API reference, getting-started guide, support, engineering blog, signup flow, authentication, and 23 more developer resources.
