When former Facebook CTO and VP of Engineering Adam D’Angelo left the company last May, it wasn’t clear what he would do next. Now, D’Angelo and Charlie Cheever, the former head of engineering for Facebook Platform and Facebook Connect, who also recently left the company, have founded a new startup called Alma Networks. The company is based in Palo Alto and has raised a round of seed financing.

While the two aren’t ready to talk much about what they’re doing publicly, a recent job listing from the company describes it as “a community-generated database of the trusted information that interests people most.” It goes on to say:

Some of the challenges are highly algorithmic, such as coming up with ways to organize and categorize the information effectively so that users can efficiently find what they need; others are very technical, such as working to make a web application that is complex while still being very fast; and many of the challenges are in product design, such as figuring out a way to set up and grow a healthy community and constructing intuitive interfaces for users.

D’Angelo and Cheever aren’t the only former Facebook exec-lead engineer pair to go into business together in recent months. Last October, Facebook co-founder Dustin Moskovitz and lead engineer Justin Rosenstein left to start an enterprise productivity software company that’s still operating quietly.

Back in January, Facebook CEO Mark Zuckerberg announced leadership changes on the Facebook Platform team that included Mike Vernal taking over for Cheever as head of Facebook Platform and Connect engineering. At the time, Zuckerberg said Cheever would be moving over to work on “more new initiatives.” Vernal was a core member of the team that built and launched Facebook Connect last year.
