Charthop

ChartHop is an AI-powered people-analytics and workforce-planning platform that unifies HR, finance, and business data in a single system so HR and finance teams can run headcount planning, compensation cycles, performance and goals, engagement, and org reporting without spreadsheets. ChartHop exposes an extensible REST API (738 operations, Swagger 2.0) that reads and updates the entire org graph — people, jobs, groups, compensation, goals, forms, time off, approvals, and more — plus a webhook/event system and a first-party MCP server (JSON-RPC 2.0 over Streamable HTTP, OAuth 2.1 + PKCE) for AI agents. Added to the API Evangelist network as an a16z / Cowboy Ventures portfolio company and enriched from its live developer surface.

Charthop publishes 1 API on the APIs.io network: REST API. Tagged areas include Company, HR, People Analytics, HRIS, and Workforce Planning.

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

Charthop’s developer surface includes documentation, API reference, getting-started guide, authentication, changelog, support, engineering blog, and 25 more developer resources.
