Momentum
Cekura is a San Francisco-based SaaS platform founded in 2024 and backed by Y Combinator for automated testing and monitoring of production Voice and Chat AI agents. The platform simulates thousands of conversation scenarios with different personas and accents before launch to identify weaknesses, then monitors real conversations in production for hallucinations, interruptions, latency, and failed Tool calls. Cekura offers native integrations with popular Voice AI stacks (Retell, Vapi, ElevenLabs, LiveKit, Pipecat) as well as an MCP server for Coding agents like Claude Code or Cursor. Billing is usage-based via Credits, with a free developer plan and custom Enterprise solutions available.
