Miles Grimshaw (X, LinkedIn) is an investor at Thrive Capital. He’s spent most of his career there, there, partnering with founders at the early stages of company building, including Cursor, Turbopuffer, Chai Discovery, Mesh Optical, Revel, XDOF, Socket, Benchling, GitHub, and many more. Miles was also briefly an investor at Benchmark before returning to Thrive in 2024.

The conversation focuses on Miles’ appetite for change and continuing to begin anew, again and again. That starts with “adventure racing” as a teenager, and continues through his career as an investor in search of world-changing companies.

We talk about how Miles proactively puts himself in position to work with great founders in a style that resembles courtship, his disposition of impatient patience, and why he loves change. The latter includes the dramatic shift in his primary domain: software. As the underlying assumptions for software businesses change due to AI, what traits will great companies have? And what moats if any will persist? Is software investing over?

Miles also talks through how great companies and founders go where they are looking, prioritizing customers that help you live in the future, the learned intuition of greatness, and joining the expedition squad alongside the founders Thrive partners with. Finally, we talk a bit about Thrive, his departure to and return from Benchmark, and endurance.

I hope you are inspired to find an infinite game where you are excited to see the stone roll back down the hill and begin to push again.
