Great news rolled in today. Leanplum, a Techstars Seattle alumni, just closed a series A round. Leanplum is out of the Techstars Seattle 2012 class. The two ex-Google founders Momchil and Andrew worked immensely hard during the three-months program, or as they call it “our ninety day week”. It initially paid off with a $825k seed-round raised upon Demo Day, and now an additional $4.8m from Shasta Ventures.
