Rental search service Zumper has taken a healthy first institutional round of funding from a few well-known Valley firms.

Kleiner Perkins led the $6.5 million round with participation from previous investors NEA and Dawn Capital. The funding will be used for growth acceleration.

Kleiner Perkins’ Chi-Hua Chien will join the Zumper board.

Using Zumper, apartment hunters filter the listings based on location, rent, number of bedrooms, and pet-friendliness. Zumper then sorts the available listings and presents them as pins on a map, along with neighborhood info and pictures.

Zumper’s mobile B2B product, Zumper Pro, “has grown at a rate of over 25% month on month since the product launched in April 2013,” according to a statement on the news.

“Our Pro product is mobile first, and we’re betting big that this is the future of real estate,” founder Anth Georgiades told VentureBeat in a recent interview.

“Real estate is, after all, an industry that is often practiced in the field. Many landlords and brokers post directly to our site through Zumper Pro, so these are real listings posted in real-time, and we get many of these listings before any other search site because we power the software.”

Zumper was founded in 2012. This round brings the company’s funding to date to $8.2 million.
