Grey Baker is a Cambridge-educated mathematician turned software entrepreneur best known for bootstrapping Dependabot to $14k MRR before selling it to GitHub in 2019, then growing GitHub Advanced Security to $140M ARR. A former McKinsey consultant who taught himself to code in six months, cycled 30,000km around the world between startups, and co-founded YC S23 company Pincites (AI contract negotiation, acquired by Filevine in 2025), he now serves as a Visiting Partner at Y Combinator.
Tom Blomfield OBE is a British serial entrepreneur best known as co-founder and former CEO of Monzo, the UK's most-loved challenger bank that grew to serve 15% of the UK population.
