We just passed the 20 billion ads served mark. Along the way we’ve assembled a world class team, and we’ve built fantastic relationships and friendships with our amazing publisher and advertiser partners, who have really been the fundamental driver of our growth. We’re both excited and humbled by the progress that has been made thus far. I just took a look at the original business plan, and according to what at the time I thought were absurdly lofty projections, we should have served 3.5 billion impressions at this point.

Obviously 6x’ing your original plan is awesome for any startup, but even more so considering the progress we’ve seen in just the last twelve months.

In march of 2007 we had 1500 publishers, were serving about 500M impressions a month, didn’t have a graphical ad unit, and the company stood at 30 employees.

12 months later we have over 3900 publishers, are serving 2.5B impressions a month, serve millions of graphical ad impressions on any given day, and have over 60 employees diligently working on solving all the interesting problems mobile has to throw at us.

I’m most excited by the general feeling that we are really still just at the beginning. Without getting into details, after spending the bulk of our time on back end infrastructure for the first 18 months, we’ve now switched gears and have a pipeline of product enhancements and features that rivals anything we’ve ever done at the company. The next six months will see an amazing set of product releases that will really address many of the fundamental issues facing mobile advertising.

So 20 billion has come and gone, but we are just now getting started.
