The E2E testing layer for AI-driven development
Lark is a San Francisco, California-based software company that provides an end-to-end testing layer specifically designed for artificial intelligence-driven development workflows. The business-to-business platform enables engineering, product, and design teams to write automated software tests using plain English instead of maintaining complex test code scripts. Through this natural language approach, developers can continuously validate user interface dashboards, application programming interfaces, software development kits, and standard product flows. The system is built to execute these automated checks directly across feature branches, continuous integration pipelines, and live production environments to ensure software reliability. Operating with a core team of two employees, the early-stage developer tools startup is backed by Y Combinator as a participant in the accelerator program's Summer 2025 batch. To address quality assurance challenges in modern DevOps and artificial intelligence automation, Lark was officially founded in 2024.
Lark has raised $255.6M across 9 funding rounds.
