Zillow Group hackathon

Over 100 coders descended on Zillow Group's San Francisco offices in SOMA this weekend to build products based on the real estate tech giant's abundant data and the MLS data optimized for developers by the firm's Retsly subsidiary.

HageyMedia checked out the action on Saturday at about 6 p.m., roughly 10 hours into the hackathon. It ran all night and the winners will be announced today at the conclusion of the demos, which are happening now.
