Hi there, I'm Dannie.

I'm a seasoned leader, entrepreneur and growth advisor living in San Francisco, California.

I'm an early engineer and senior leader at Pinterest. Over the last 6 years I helped grow Pinterest's engaged user base from 20M users to over 200M users, leading the growth engineering team.

I also advise early to late stage companies on their user growth. I specifically help scale their growth strategy, tools, processes and team.


Previously, I was a co-founder of Foodoro, a YCombinator & angel-funded startup lab responsible for products such as: - an online marketplace for artisan food - yelp for b2b products and services (currently in private beta) - daily deal discover engine (now defunct)

In an earlier part of my life I studied mathematics & computer science at the University of Waterloo in Canada. During that period I worked at companies such as Microsoft, Sybase and BMO Financial Group.
