X26 is launching a fund!
Since 2021, we've invested over $1M via SPVs into ex-McKinsey founders, with strong performance (4.5x+ net TVPI). Our portfolio has gone on to be backed by the best in the world – YC, A16Z, Sequoia, Benchmark, and General Catalyst. The main constraint hasn't been access to great companies, it's been the speed at which we can execute deals.
That's why we're formalising this into a dedicated fund – built to back McKinsey founders from the outset. We had over $5M in inbound interest for our inaugural fund!
We're aiming for our first close to take place over the summer. For those of you that have registered your interest, you should have received a commitment letter to sign.
For others, if you would like to learn more, reach out to [email protected] or book a call here. If you would like to commit to the fund, you can sign a non-binding commitment letter here.
Before then, we have some amazing founders in our network that are currently raising.
