Holly Hester-Reilly

Product Leader & Founder


Holly Hester-Reilly is the Founder of Product Science Group and the host of the Product Science Podcast. Holly is a former Columbia University research scientist and has spent the last 15 years leading product initiatives at startups, high-growth companies, and enterprises like FalconX, MediaMath, Shutterstock, GTreasury, The Lean Startup Co, Unilever, Capital One, and Weight Watchers. With those experiences she has developed the Product Science Method, a framework to discover the strongest product opportunities and lay the foundations for high-growth products, teams, and businesses. 

Her team at the Product Science Group partners with startup founders and product leaders to share this framework, helping them to figure out which product growth opportunities they should pursue and build the product management skill to deliver on their goals. 

Holly also teaches at NYU Stern School of Business as well as public and private workshops and has spoken about building high-growth products for events such as Lean Startup Summit Europe, Women in Product's Annual Conference, ProductTankNYC, Parsons School of Design, and INDUSTRY: The Product Conference.


I believe that we can use technology to solve real problems for real people, and I want to help create sustainable, enjoyable experiences for high-growth tech products, teams, and companies.
