Mark Choey is a co-founder, partner and agent of Climb Real Estate in San Francisco. Choey’s brokerage is considered one of the most forward-thinking in an already creative real estate region. It launched an innovation division, Climb Labs, labeled as Climb’s “playground” for technology. Realogy subsidiary NRT bought Climb in August, but Choey and his leadership were left untouched to continue the firm’s brand. He is also one of the top-producing condo sellers in the Bay Area and a member of Zillow’s and Sindeo’s advisory boards.
