He has just left that firm and joined another, Charles River Ventures, as a general partner.

Amp’d Mobile is one of the most catastrophic investments in VC history, and Auerbach was on its board. While it’s not clear if the fiasco is the reason for Auerbach’s departure from Highland, he is landing on his feet. At Charles River Ventures, a respectable firm which already has around fifteen investments in mobile companies, Auerbach joins the company’s East Coast office to explore and expand investments in the mobile market.

We asked Auerbach about his role in the Amp’d fiasco, and he said he preferred not to comment. He said he likes to take “big swings on capitally intensive businesses going after big markets with monolithic carriers and companies that could change the world.” He said the investment in Amp’d was one of those swings that “just didn’t work out.” He also says he is glad to be involved in the project but said, “I’m focused on the future, and not the past.”

We asked Charles River’s partners about their decision to bring Auerbach on board. Bruce Sacks, a parter at the company, pointed out that that he “can’t name a successful venture capitalist that doesn’t have a huge crater” and that Auerbach has led a number of successful investments since 2000 — the year he made the switch from Wall Street Journal writer to venture capitalist.

Most notably, he co-led an early-stage investment in Starent Networks (STAR), which makes software and hardware for the distribution of multimedia to mobile phones. Starent had a $115 milion IPO in June. Auerbach also took the reins on an investment in Optasite, which has grown into the fifth largest wireless tower company in the States.

When it comes to the future, he is “cautiously optimistic” about the mobile space, and that there are significant opportunities in the spectrum and in mobile services.
