Paperplane

Paperplane is an AI sales-productivity tool (Y Combinator W23, backed by Bloomberg Beta) that automatically takes notes on sales calls and keeps a rep's CRM up to date. It connects to a team's calendar and to conversational intelligence and call-recording tools such as Gong and Chorus, transcribes and analyzes each call, then writes the results back to Salesforce — updating opportunity fields, notes, and action items so sales teams spend less time on manual CRM data entry and stay on top of their deals. The product is organized around opportunities, calls, and notes, with integrations for Google Calendar, Gong, Chorus, and Salesforce. Paperplane appears to have wound down: Y Combinator lists the company as Inactive (and now describes it as a credit risk management platform for builders' merchants, so it pivoted at least once before stopping), its marketing site presents no TLS certificate, its application host returns a Vercel 402 DEPLOYMENT_DISABLED, and its API host is an Envoy ingress that 404s every path with an empty body. Two surfaces remain live: a GitBook documentation site — which is an unfilled starter template carrying GitBook's own placeholder copy, last updated three years ago — with an llms.txt index, and a Clerk-hosted OpenID Connect identity instance at clerk.paperplane.ai that still serves real OIDC and RFC 8414 discovery documents. There is no public developer API, OpenAPI definition, SDK, MCP server, or agent card.

Paperplane is profiled on the APIs.io network. Tagged areas include Company, Sales, CRM, Salesforce, and Sales Automation.

Paperplane’s developer surface includes documentation, getting-started guide, authentication, and 7 more developer resources.

  detail: Paperplane has wound down — Y Combinator lists the W23 company as Inactive, app.paperplane.ai returns Vercel 402
    DEPLOYMENT_DISABLED, api.paperplane.ai is an Envoy ingress that 404s every path with an empty body, and www.paperplane.ai
    presents no TLS certificate at all; the only live surfaces are a never-completed GitBook template (still carrying GitBook's
    own placeholder copy) and a Clerk OIDC instance at clerk.paperplane.ai.
