The real problem

Car ownership is rigged
to keep you guessing.

~$1,200

Average overspend on repairs. Every single year.

Not because they're careless—because they walked in without data. Byouma shows you the fair price before you nod at any estimate.

Industry repair pricing data
68%

Of breakdowns were predictable. Weeks earlier.

Brakes wear on a schedule. Batteries fail inside a mileage window. Most apps alert you after the tow truck. Byouma tells you before the first symptom.

NHTSA data analysis
Millions

Of safety recalls. Completely ignored.

Manufacturers issue the recall. Owners never hear about it. Byouma checks your exact spec against every open recall and fires a hard-to-ignore red alert.

Our story

Built by people
who got burned first.

"We got quoted €1,800 for a job that should have cost €600. The worst part wasn't the money, it was knowing we had absolutely nothing to push back with."

That conversation is what started Byouma. We spent months reverse-engineering how repair pricing actually works, what dealers charge and why, what real labor times look like, how parts markup functions in the real world. The data exists. It just lives in manuals and trade databases most people will never see.

Byouma puts it in your pocket, for free. Everything we build next comes directly from what you tell us matters most.

Real
We launched with the things that matter pricing intelligence and failure forecasting.
More features shipping every week based on real feedback
Open
We're honest about what Byouma can and can't do right now. No marketing speak.
