Key insight: Type safety in Python is a solved technical problem but an unsolved product problem — teams skip it because the friction of setup and CI integration exceeds the pain of occasional runtime errors, until they hit a costly production bug.

The Problem

Python developers constantly ship type errors to production because type checking (mypy, pyright) isn't enforced in CI pipelines, and existing tools require manual setup and don't aggregate findings across teams. Engineers waste hours debugging runtime TypeErrors that static analysis would've caught.

Target Audience

Mid-size engineering teams (10-50 devs) using Python with existing CI/CD pipelines who want type safety without full mypy/strict mode enforcement friction

Why Now?

AI-powered code analysis tools are commoditized now (making AST parsing easier), and Python adoption in startups has exploded without corresponding type safety practices.

What's Missing

Existing type checkers are developer tools requiring setup; there's no SaaS wrapper that installs in 2 minutes and reports type debt as a team metric like code coverage.
