AN UNLIKELY ORIGIN
PRIMAE is a Brazilian early-stage startup — though it has been nearly a decade in the making.

TEAM
WHAT UNITES US IS A GENUINE DESIRE TO LEAVE A BETTER WORLD FOR FUTURE GENERATION
Our senior team brings together researchers and professionals from government, academia, and both small and large companies, with backgrounds spanning aerospace, Formula 1 racing, defense, power generation, semiconductors, IT, and early AI research.


We also share a lifelong passion for engines.
Many of us have worked with nearly every type — piston, rotary, turbine, ramjet — and across fuels including hydrogen, ethanol, methane, gasoline, diesel, and jet fuel.
​
The result is an evolutionary synthesis of 150 years of engine development: a new kind of engine, more efficient and capable than anything before it.
​
Building on fundamental research from Stanford University, we have completed laboratory prototype testing and are now moving toward MVP development and field deployment.
