Facebook Co-Founder Dustin Moskovitz founded workplace collaboration company Asana in 2009, but the Silicon Valley startup is in the news again, having received a sizable payment from PayPal and others.

PayPal Co-Founder Peter Thiel led a group of investors who recently gave Asana $28 million. Moskovitz, who also took several Facebook employees with him when he started the company, was a Harvard roommate with Facebook Co-Founder and CEO Mark Zuckerberg. Asana isn’t a Facebook knockoff, though. It describes itself more as an alternative to email for the workplace.

Asana’s goal is to get away from email and whiteboards and build toward a more cohesive workplace. The company originally offered its software for free, but recently rolled out a premium service with more features.

Altogether, the company’s worth is pegged at about $280 million.

Asana Co-Founder Justin Rosenstein, another former Facebook employee, talked with Reuters about what the investment means to the company:

This investment allows us to attract the best and brightest designers and engineers.
