About

Mike Casas joined Greater SumVentures in 2019 and serves as Managing Director and General Counsel, overseeing legal strategy and M&A execution across the firm’s investments. A seasoned private equity attorney, Mike brings seven years of experience at large international law firms, where he advised sponsors and founders on leveraged buyouts, venture capital investments, and complex growth transactions.

Over the course of his career, Mike has consummated more than 250 private equity transactions, giving him deep insight into deal structuring, negotiation dynamics, and risk management. At GSV, he plays a central role in guiding transactions from diligence through close—working closely with founders to align expectations and navigate complexity with clarity and pragmatism.

Mike is particularly interested in partnering with early-stage companies that have strong products and market understanding but need support across go-to-market strategy, payments, and technology infrastructure. He believes successful partnerships begin with founders understanding the full spectrum of capital options—and appreciates GSV’s flexibility in tailoring structures that meet both business needs and long-term goals.

What Mike enjoys most about investing is the problem-solving inherent in dealmaking: understanding what each party needs, bridging gaps, and arriving at outcomes where everyone can win.

Q&A

What is your favorite book?

Brothers Karamazov. It’s a slog to get through, no doubt, but there’s bright hope and beauty amidst all the morality, tension, moodiness and contemplation. Life reminds me about it often.‍

What advice would you give your younger self?

Whatever you decide to do, follow through on the time and effort to become an expert at it. The 100-hour weeks are awful and you will have so much doubt, but it’s worth it in the end.‍

What do you wish more founders knew before taking on capital?

The differences between the banner investment strategies of debt financing, boot strapping, angel funding, true venture capital, growth equity, and traditional private equity. If there was a better understanding of what is best for them and what their company needs, then we can discuss what flexible groups like GSV can do within some or all of those strategies.
