Ramp

Finance automation platform for corporate cards, expenses, and payments.

Ramp built Ramp Inspect, a full-context background coding agent, on Modal — spinning up full development environments in seconds with Modal Sandboxes — and uses the Vercel AI SDK to build semantic search across internal assets. Engineering runs on Claude Code, including an On-call Assistant that root-causes every incident, and the team has put Claude Fable on large refactors of its Python monolith.
