Owen Brake
Founder/CEO
Multi-disciplinary engineer with a track record of building across industries—from high-performance brake systems to GHz FCC compliance and scaling production SQL databases with 10B+ records.
Previously developed motor controllers at Tesla. Held diverse engineering roles at Neuralink, Apple, Parallel Systems, and Ford.
Mechatronics Engineering graduate, University of Waterloo. Led the Formula Electric team, driving innovation in EV performance.
Ethan Childerhose
Founder
Co-founder and CTO at Steinmetz. Previously at Rocketlab, Nvidia, Tesla, and Neuralink. I've worked across the hardware stack from analog transistor level design to 100 lb mechanical fixtures for environmental testing. My work has reached the moon, been mass produced millions of times, and processed the faintest of signals from the human brain.

Is this you?
If you're behind Steinmetz: acceptance into a YC batch is one of the few weeks a young company gets looked up by people who matter — investors, other founders, press. FoxPlug turns the commits, deploys, and releases you're already making into that story automatically, so anyone who looks finds something current. GetFoxChat puts a guide on your own site so the people YC's own page just sent you don't read one line and leave.
