Founder & General Partner
A technical investor who still builds.

Brennan is an engineer with a background in optics and hardware. He has founded more than six companies, with three exits across energy, manufacturing, logistics, and consumer — and still operates today as the CEO of a hardware company.
At Eigenstate he runs everything himself: sourcing, diligence, and the decision. Deals come directly through technical communities rather than syndicates, and he evaluates the engineering firsthand, from reactor physics to semiconductor architectures.
“Brennan has been instrumental in aiding our business development and contributing to the technical aspects of a demo satellite.”
