Justin Ross Hartfield, Entrepreneur

Hi, I'm Justin and thanks for learning more about me. I'm a 32 year old serial entrepreneur, which means I've lost a lot of money chasing zany business ideas since I was a tween with relatively little success.

Currently, I serve as Chief Executive Officer of Weedmaps.com, the largest online directory and social network for marijuana users and medical marijuana patients. I also serve as a Director of The Prometheus Institute, a 501(c)(3) non-profit think tank dedicated to utilizing technology to engage America's youth. Our current project right now is called SimpleGov.

I've been intimately involved in marijuana policy reform since 2008 and I serve as the Treasurer of the National Association for Reforming Marijuana Laws (NORML) and on the Board of Directors for the Marijuana Policy Project (MPP).

I'm also a General Partner at Ghost Group, a holding company for various marijuana assets like Marijuana.com, MMJ Menu and of course Weedmaps.com.

A 'webmaster' since my 12th birthday, I've held numerous positions in the internet technology field, concentrating on internet marketing. I have a BS from the UC Irvine in Information and Computer Science from 2005. I'm also a UCI Merage B-School graduate school dropout ;-) Zot zot!

A long-time resident of Orange County, CA, my other interests include golf, swimming (especially in Maui), philosophiszing, Eastern religion, fantasy football, design, playing pot-limit crazy pineapple with friends, dining with wife Melissa, fine automobiles, earthy pinot noirs, and spicy sativas.
