Homesnap (a CoStar Group company)
2023 Rank: 119
Mazur runs Homesnap, the real estate agent productivity tool CoStar Group acquired for $250 million in 2020. In late 2022, CoStar merged Homesnap with Homes.com, which it has relaunched as its primary retail real estate marketplace. Homesnap’s long partnership with the Broker Public Portal ended in 2022 as CoStar looks to leverage the tool as it sees fit, unencumbered by any external agreements.
