YC Summer 2026 (S26) founder

Michael Muzzin

Founder of CarSignal, The AI Operating System for Auto Shops.

Company

Michael Muzzin is listed as a founder of CarSignal. CarSignal is the AI-native operating system for independent auto repair shops. Most shops still run each repair across disconnected management software, scan tools, parts catalogs, service information, texts, spreadsheets, and knowledge kept in technicians’ heads. That fragmentation slows diagnosis, creates duplicate processes, and leaves customers waiting. CarSignal connects the full repair process in one system. AI agents research vehicle-specific failure patterns and surface the tests that confirm or rule out each cause. The same system carries each job from booking and intake through inspections, estimates, parts, approvals, payment, and follow-up, so technicians spend less time searching and updating systems and more time fixing cars.

    Just like the gt2rs, @trycarsignal is fast. We’ve grown from 2 shops to over 40 across the span of 2 months. 🚀🚀 We’ve got more exciting tech to share, but that’s all coming later:). Stay tuned!

    This was me replacing my clutch on my 06 Mini Cooper S. I do not miss working on it, but it did help me hone my skills to make @trycarsignal possible. Thank you @MINI for making a blast of a little car.
