HARRY BENDIX-LEWIS

About

Two-time founder. Full stack engineer. Currently building Lingly , an AI language learning platform for frontline workers. Previously co-founded a consultancy I exited via co-founder buyout.

I've done 0→1 twice. I've also shipped production code at a $13bn hedge fund and advised the UK government on supply chain security.

I like solving problems that actually need solving.

Based in London 🇬🇧
