I build products, companies, and occasionally ridiculous machines.

Klein Labs is the workshop and running record of Kit Klein—useful software, ambitious ventures, and physical things made to solve a problem or satisfy a curiosity.

Selected work

Things that made it out of my head.

Not a portfolio of perfect outcomes. A record of useful products, hard problems, and things worth making.

Monster Machine

A Power Wheels Jeep body, a shortened 1993 Polaris frame, an electric drivetrain, and Toyota power steering. Built for grass. Kept because every kid loves it.

Twin-Turbo GT350

A 2016 Shelby GT350 converted with a Hellion top-mount twin-turbo system. Built over one winter, tuned for a little over 700 wheel horsepower, and kept as a usable street machine until it was sold in 2025.

About the builder

Klein Labs is the workshop.
I’m Kit Klein.

I work across products, companies, software, systems, and physical builds. The medium changes. The instinct is usually the same: understand the real problem, remove what does not belong, and make something that works in the world.

Now / August 2026

Building a better home for the work.

The current job is this archive: gathering the projects, documenting the decisions, and giving Klein Labs a site that can grow with whatever gets built next.
