Safi Shamsi built Graphify in a single weekend as an open-source tool that now powers major AI coding assistants, boasting millions of downloads and broad adoption.

Graphify Labs joined Y Combinator’s Summer 2026 cohort as a solo founder, drawing questions about scale, even as YC partners lauded the speed and execution.

The ecosystem around Graphify is vibrant, with more than 130 external contributors, over 150 releases since launch, and a waitlist exceeding 4,500 enterprise teams for Penpax.

Graphify delivers lightweight mapping infrastructure that creates detailed visual maps of software component connections, helping users navigate large codebases without reconstituting repository context during queries.

The company is expanding into Penpax, an enterprise-grade engine built on Rust designed for high-performance software environments, signaling a move toward enterprise-scale deployment.

Rapid scale is evident, with over 4 million cumulative downloads since April, peak daily downloads around 65,000 to 79,000, and integration with more than 15 AI coding platforms including Cursor and Claude Code.
