Mike Shaw - From Accidental Chemist to PFAS Destruction CEO

from The Fundamental Molecule

Taking the reins at a company is no small thing, especially when your predecessor in the CEO role was someone as exceptional as Julie Mullen. Julie had built the basis for Aclarity, and following her was not for the faint of heart.Mike Shaw is not faint of heart. He is an exceptional technical and product leader with fascinating experiences at Evoqua and Nanostone, and he has been leading the development of the Aclarity product up to its first commercial deployments late last year. Now officially in the CEO role - congratulations, Mike - I wanted to hear how he reflected on his journey, the transition from a technical leader to a company leader, and talk about the development of the PFAS market, among many other things, including a certain Manchester United manager.

Bias doesn't help anyone.""Having a product management function prevents silos and keeps the team aligned.""Surround yourself with diverse people. You need pessimists, optimists, detail-oriented, and big thinkers.""It's not about speed, it's about velocity. Direction of travel really matters.""Constantly second guess yourself.
