About Mark

I'm an old school serial entrepreneur, having founded and/or run five important tech startups since 1994. At my core I'm a product guy; the essential passion I have is for seeing the possibilities that platform changes will enable -- e.g. I was the first person in the world to bring fantasy sports (and hence social gaming) to the internet in 1994, as I saw the possibilities that networked technologies would provide for entertainment. I love building great, fun, cohesive teams as well.
