Realogy joins large real estate companies Keller Williams Realty, RE/MAX and Compass in providing custom, proprietary tech for agents in its network. It represents a slightly different approach to these companies, however; it has leveraged strategic partner OJO Labs to build the tech instead of building the technology in-house. Realogy participated in OJO Labs’ $75 million Series C round in March 2019 and its $20.5 million Series B round in May 2018.
