 > I invest in pre-seed and seed devtool and datatool companies with Alven (Algolia, Grafbase, Dataiku, etc.), and selectively in web3 tooling (i.e. NFTport). I have been coding for derivatives trading desks since 2005, and have built internal data tooling for asset managers since then. I angel invest $5-25k in technologies that excite me, and mainly support the European ecosystem. Love working closely with founders on product strategy, GTM, key hires, fundraising and market intel and connectivity.

+  > I founded Hackerbay backed by NFX and write angel checks ($5-15K) in open source or dev tool startups. I invest in startups globally, but prefer legal entities I know (Delaware, Europe, Singapore). I can help best with everything product, distribution, fundraising, and eventually when needed, infra scaling. The best way to reach me is DM on Twitter.
