At PropellerHeads, we’re building foundational infrastructure for decentralized finance (DeFi) on Ethereum. Our mission is to eliminate middlemen and technical barriers so that anyone with an internet connection can trade any asset on equal terms with the largest and most sophisticated participants.

After eight years of building in AI and biotech, we transitioned to crypto, and now with the backing of over 80 VCs and angel investors—including General Catalyst and Delphi Digital—we're scaling fast.

We’re a small, tightly-knit, and collaborative team with a strong track record of mentoring junior engineers and providing real opportunities for growth and ownership.
