A year after raising a $5.5 million Series A and moving into ad tech for real estate, Placester announced it has closed $15 million in Series B funding led by New Enterprise Associates.

In a news release, the Boston startup said it plans to double its staff over the next year, to 100 employees from 50.

Placester, a Techstars Boston 2011 graduate, started out by offering software that helps real estate agents launch websites featuring their listings. A year ago, the company inked a deal to replace the digital real estate sections on local newspaper websites with a new Placester real estate portal.

In the release, Placester CEO/co-founder Matt Barba cited the shift in the way consumers are buying things—including homes—toward digital. “Searches begin online and people expect real estate agents and brokers to deliver a Facebook, Google or Amazon-like experience,” Barba said—which is what Placester is seeking to empower agents and brokers to do.

Placester has now raised $22 million in total. Previous investor Romulus Capital also took part in the new round.
