Peter Brooks - Building an Infinite Compounding Machine

Out of 910 graduating students in the Class of 2014 from HBS, three went into water. Of those three, only Peter Brooks and I remain. And, meaning no offense to all our wonderful classmates, I'm glad it's him. Peter is just a really great guy. A former Marine, he worked across a variety of fascinating opportunities before setting up Sylmar Group. He and his partner Michael have been hard at work creating a compounding machine in water, building with an infinite holding period. And, as you will hear, it has developed exceptionally in the six years since it was founded. I have been looking forward to this for a long time because there are few people as thoughtful, practical, wise, self-effacing and talented as Peter. I was also amazed to find out that this is the first time he has talked about the Sylmar story on a podcast. So you're literally hearing it here first. Please enjoy my conversation with Peter Brooks.
