Co-founder / CEO of Atum Works Recovering Caltech physicist, Brains in Silicon Lab (Stanford) dropout. Previously built the world’s fastest‑burning hybrid rocket engine before serving as a civil servant at NASA in optics, electric propulsion, and attitude‑control systems, where I collaborated with Nobel laureates and NASA leadership on missions including Starshot, Starshade, and Europa Clipper—and won NASA’s “Most Visionary Concept” Award.

Matteo Kimura
Matteo KimuraFounder
Caltech

Cofounder at Atum Works. I'm a computational mathematician out of Caltech, applying math and algorithms to controls, tech, and tough engineering problems. I've worked on tools used by tens of thousands and robots flown in space, between rooftops, in the desert, and near-space. I've written lunar flight software, led multi-million dollar NASA proposals, and served as systems engineer and flight director on an active space mission steering real spacecraft with code, math, and too much caffeine.

Caltech

I co-founded Atum Works after completing my engineering thesis at Caltech on the multi-material additive manufacturing of hierarchical mechanisms. I worked on the Mars helicopter at the Jet Propulsion Laboratory. I co-founded Caltech Air and Outer Space, securing over $ 600,000 in research grants for advanced technology development, and led the development of electrodynamic dust-shielding hardware to receive NASA’s “Best Product Development Award.”
