Welcome Ali Rosenthal

I’m very happy to announce that Ali Rosenthal has joined Greylock as an Executive-in-Residence. Ali joins us from Facebook where she was most recently the head of Mobile BD and the Global Mobile Operator Team.  Ali will work with the consumer team at Greylock leveraging her wealth of experience in consumer Internet and mobile companies, as well her background in finance to evaluate opportunities and aid the portfolio.

Like all of us at Greylock, Ali has been an operator. During her five years at Facebook, Ali led business and corporate development efforts in core social, growth, international and mobile products.  As one of the first business development executives at Facebook, Ali was a driving force within the company – especially within its mobile team – early in its game changing trajectory; she joined Facebook in 2006 when there were fewer than 5M active users and no mobile users.

From early on, Ali worked on mobile initiatives at Facebook and in 2008, helped form the original mobile team to formalize and grow Facebook’s mobile presence through key strategic distribution and product partnerships.  Ali and the mobile team developed, launched, and distributed Facebook mobile products with over 350 mobile operators, OEMs and developers worldwide.  During this time, facebook’s mobile user base grew from ~100k users to over 250 million active mobile users.

We firmly believe that all successful consumer companies require both strong social and mobile platforms for distribution and monetization. Ali was a leader in both areas for the preeminent social network of our time. I’m really looking forward to learning from Ali’s expertise in mobile and social. I know our portfolio companies will benefit from it as well.

Maybe even more importantly, Ali has developed lasting relationships and respect based on values we hold near and dear – integrity, drive, teamwork, and leadership.

In addition to her achievements in the business world, Ali is also an accomplished athlete.  For two+ years while at Facebook, Ali raced as a CAT 1 pro cyclist for the TIBCO Women’s Professional Cycling Team. She’s run 4 marathons, her fastest (NYC) was under 3:00. And you might ask her about a 5 to 1 ratio of dishing out stitches to enduring them during her four years on the Brown University women’s lacrosse team.
Welcome Ali!
