What does CarSignal do?
The Smart Operating System for Auto Shops.
What problem does CarSignal solve?
Auto shops run intake, diagnostics, estimates, scheduling, and payments as disconnected steps, so information gets retyped at each handoff and quotes can take hours to reach customers.
What's CarSignal's solution?
CarSignal is an AI operating system for auto shops that keeps every car's record connected from check-in through diagnosis, quote, approval, repair, and payment, backed by an AI diagnostic copilot and customer-facing status updates.
What makes CarSignal different?
It pairs an OEM-data-grounded diagnostic copilot that scores repair recommendations with confidence percentages against unlimited users on a month-to-month plan, unlike competitors' per-seat monthly subscriptions.

Backed by Y Combinator (S26); founded by Michael Muzzin and Junaid Popalzai.
