About Sebastiaan
I'm a Dutch serial entrepreneur and angel investor. Over the last 15+ years I've founded four companies — most recently building Gameye into multiplayer-gaming infrastructure trusted by studios like Bungie and Remedy.
I've exited three of my ventures — Tail (acquired by Quantum Group), Signkick (merged with LiveDOOH) and WEBIQ — so I know the full arc first-hand: starting from nothing, fighting through the hard middle, and reaching a successful exit.
As an angel I've backed 56 startups, getting in early on Revolut, Kraken, Monzo and Moonpay. I work with founders on what actually moves the needle — fundraising, growth, focus, and the board-level calls that make or break a company.
