The primary community for ex-McKinsey founders, investors & operators

X26 is the definitive home for ex-McKinsey founders, investors, and operators.

We support ex-McKinsey founders from Day 0 — before the raise, before the launch — and stay with them through their second and third ventures. Our community of 2,500+ spans the full arc of the startup journey, from first-time founders to seasoned operators and investors.

Every two weeks, we're somewhere in the world. Between events, we support our members through fundraising, YC applications, founder retreats, co-founder matching, and partnership events with the likes of MIT and Google.
