Quattro co-founder launches mobile-app tool startup Session M

Lars Albright, the entrepreneur whose technology now powers Apple’s iAds, has a new startup, and it just raised a $6.5 million round led by famed venture capital firm Kleiner Perkins Caufield & Byers.

The Session M website is pretty bare right now, featuring a brief note from Albright that only hints at what the Boston-headquartered company will be up to:

Our team at session M loves how mobile apps are changing the way people interact with content. As the app ecosystem continues its explosive growth, developers are looking for new ways to achieve higher rates of engagement, and deliver even more rewarding experiences to their users. This is where session M steps in.

Albright previously co-founded Quattro Wireless, the mobile ad startup that was acquired by Apple for $275 million. Quattro formed the basis of the company’s iAd platform for high-quality, media-rich mobile ads, and Albright led business development on the iAd team. Albright now writes that he had “an incredible experience at Apple helping to launch and grow the iAd business.”

The startup was just written up in BusinessWeek as one in a wave of companies founded by entrepreneurs who left Apple — a wave that also includes mobile social app Color, iPad magazine Flipboard, and tablet textbook maker Inkling.

Session M’s funding comes from Kleiner’s iFund for iPhone and iPad startups, as well as Highland Capital Partners (which also invested in Quattro) and “notable mobile industry leaders” whose names are not disclosed.
