CarSignal on the record

What they shipped

  • From its YC profile: 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 admin, 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. (source)
  • Its own site describes it as: "The AI operating system for auto shops: intake, inspections, estimates, scheduling, messaging, parts, invoicing, and payments." (source)

Who is behind it

  • Michael Muzzin, Founder/CEO: Founder at CarSignal (YC S26). Previously electrical engineering at NVIDIA, he authored the Factory Failure Disposition Guide governing re-qualification of $300M in HGX and DGX datacenter hardware. BSEE, UCLA. (source)
  • Junaid Popalzai, Founder/CTO: founder at carsignal. prev netflix, notion, whatnot, tesla, amazon. eecs @ berkeley (source)
