About

Hi, I’m Tom Tholen — a Dutchman in my thirties and the voice behind this publication. Core9 is where I publish my thoughts, lessons learned, and insights as product management professional with a decade of experience ranging from small bootstrapped teams to enterprise orgs.

While I can say that I've learned a thing or two about building products and creating a product culture, I also know that learning will never stop.

So what is Core9...
Core9 represents the opportunity to create something remarkable by bringing together people, insights, and resources — making the whole greater than the sum of its parts.

I’m not entirely sure where this project will go, but I hope you’ll find it both useful and enjoyable to follow.
