• Bitcoin biz: Last year we discussed Xapo, a bitcoin storage and digital wallet company that had raised $20 million in VC funding from top names like Benchmark, Ribbit Capital and Fortress Investment Group. It was founded by Wences Casares, who previously had founded a digital wallet company called Lemon, which was purchased by publicly-traded LifeLock for more than $40 million. Xapo would later raise another $20 million, and just weeks ago announced an advisory board that included former U.S. Treasury Secretary Larry Summers and former Citigroup CEO John Reed.

In short, it's one of Silicon Valley's hottest bitcoin startups.

But Casares and other members of Xapo's management team also are defendants in a fraud and breach of contract lawsuit brought by LifeLock which, if successful, could threaten Xapo's very existence. Moreover, we've learned that the new advisors were not apprised of the ongoing litigation prior to signing on.

LifeLock alleges that Xapo was created by “using a product developed by Lemon employees, in Lemon’s facilities, on Lemon’s computers, and on Lemon’s dime.” Casares hasn't filed a formal response yet, but court filings suggest that he will argue that he sought and was given permission to build Xapo while still a Lemon employee, and that LifeLock has no claim on any bitcoin-related IP. Yeah, it's messy.
