Offerpal Media Acquires Ad Net Mediator Tapjoy

Looking expand its virtual payments operator more deeply into mobile apps, Offerpal Media is buying ad net mediator Tapjoy. Terms of the deal weren’t disclosed. Last summer, Palo Alto-based Tapjoy, along with other mobile ad net optimizers like AdWhirl, found itself threatened with being cut off from AdMob’s network, after the mobile ad net cited “glitches” related to ads served by companies that had been handling unsold inventory across its system. Aside from working with mobile ad nets, Tapjoy has also been venturing into the virtual goods business that Fremont, CA.-based Offerpal is focused on. Offerpal has raised $19.6 million since its founding three years ago from D.E. Shaw Ventures, which led its $15 million second round in December, as well as InterWest Partners and North Bridge Venture Partners. Release
