Biography
"Jean-Francois “Jeff” Clavier is the Founder and Managing Partner of SoftTech VC, one of the most established seed VC firms in Silicon Valley, having closed 150 investments since 2004. An early angel investor in Web 2.0, Jeff and his team have backed successful startups like Mint (Intuit), Kongregate (GameStop), Brightroll, Milo (eBay), Wildfire (Google), Bleacher Report (Turner), Fitbit, about.me, Eventbrite, Sendgrid, Fab, Poshmark and Class Dojo. The portfolio has also seen acquisitions by Groupon, Twitter, Facebook, Yahoo and AOL. The firm is currently investing out of its $55M Fund III, making 20 commitments of $500K per year in mobile/cloud saas, monetization infrastructure, marketplaces and e-commerce.

Born, raised and educated in France, Jeff graduated with a MS in Computer Science and a degree in Distributed Computing. He joined Effix, a financial services startup, as one of the initial developers while still at school and eventually led it as CTO. After 5 years, Reuters acquired the company and Jeff expanded his remit to several product and development organizations in Europe and the USA. In 2000, he moved to Silicon Valley as General Partner for RVC, the $450M venture fund affiliated with Reuters.

In 2004, Jeff left RVC to start SoftTech VC and invest in the early pioneers of Consumer Internet. Within a couple of years, he was being recognized in the media as one of the “super angels”, and in 2007, he subsequently raised one of the first micro-VC funds, $15M Fund II. After three years, and 60+ investments closed on his own, Jeff built a team and raised a larger, $55M Fund III.

One of the early VC bloggers in 2004, Jeff is now a popular conference speaker and social media/TV commentator. When he is not spending time with SoftTech’s portfolio companies, Jeff enjoys traveling, skiing, scuba diving, collecting wine and hanging out with friends and family."
