Online real estate firm Zillow Inc. (Z) finalized its $40 million-purchase of RentJuice Corp., a provider of rental relationship management software.

RentJuice announced the acquisition last month.

San Francisco-based RentJuice launched in 2009. With the merger now complete, RentJuice CEO and founder David Vivero will serve Zillow as vice president of rentals.

"Zillow is the unrivaled category leader and we’re excited to become part of the team that’s recognized as pioneering technology and innovation across the entire real estate industry," said Vivero.

RentJuice brings 31 employees to Zillow and a subscription-based suite of marketing and productivity tools.
