2018 Awards

RESO  honored more than two dozen of its members and leaders in Denver at its sold-out 2018 Spring Tech summit held April 24–26. The conference attracted more than 275 real estate technology leaders from real estate brokerages, MLSs and technology firms. Honored volunteers received personally engraved wooden cases with classic games (pictured) in tribute to the tech summit’s theme: “It’s ‘Game On’ for Data.”

Innovation Winners
Predicted Property, founded by Robert Humphreys, collects insights from predictive speech analytics enhanced by artificial intelligence to give agents intelligence on properties and improve their ability to close sales. Tapping into a RESO-provided data feed, Humphreys discovered that standardized data can be used to surface actionable data points about properties that match clients’ interests. The result is a more efficient and cost-effective lead-generation tool for agents.

MLS Data Tools, created by Shawn Whitaker, is software that solves for the tremendous amount of technical labor that is required to aggregate MLS data nationwide using automation. This white label software can significantly decrease the amount of time startups, brokers and agents spend aggregating RESO standardized data that powers industry solutions.
