Tessl

Tessl helps AI agents stay reliable and aligned by grounding their work in specs. Agents are powerful, but they can drift — misinterpreting requests, hallucinating APIs, or breaking existing features when adding new ones. Tessl integrates with most agents and uses spec-driven development to give agents (and you) a structured way to capture intent, run tests, and evolve codebases with fewer mistakes.

Every fact above is shown only where it could be checked against a source: funding against a primary source, backers against the investor’s own directory, and a location only where the company names that city on its own site. A row that is absent is one we could not source, not a zero. The summary is a written description of the company. Category is our own classification. Spotted something wrong? Tell us.
