Built by Racers

For racers. That's the whole thing.

Who We Are

MZS was started by two dirt drivers. Zach Smith and Mike Chasteen got tired of managing sponsors on paper, losing race data, and having no way to track what was working. So they built the tool they needed.

Every feature in MZS exists because we needed it. No feature creep. No "enterprise" bloat. Just the stuff that keeps a race program running.

Why MZS Exists

Running a race program is not simple. You have sponsors to track, race results to log, setups to remember, and about a million other moving parts. Most of that lives in notebooks, spreadsheets, or nowhere at all.

We built MZS to be the operating system for race teams. One login. All your data. Works at the track with no WiFi. Syncs when you're back online.

That's the promise. That's the product.
