I invest in and help early-stage startups at Matrix, where I focus on fintech, vertical software, and adjacent areas.
I previously led product at Afterpay (acquired by Square), as well as founded Bonsai (vertical software & payments) and Seiza (HR tech, acquired). And a long time ago I studied politics, economics, and philosophy at UC Berkeley and Oxford.
You can find me on Twitter, Linkedin, and Substack, and email me at mb at matrix.vc.
I write often to clarify my thoughts, learn more, and meet interesting people. Here are some popular recent notes:
