GrowthFactor AI

Website

Commercial real estate workflows are fragmented and broken. Teams make multi-million dollar decisions off of under-utilized data, and spend more time stitching patchwork data together than underwriting the deal. There’s little-to-no closed loop allowing teams to learn from their wins - and their misses. GrowthFactor was built by three MIT classmates to fix that.

GrowthFactor is building the Salesforce for Real Estate. The platform allows teams to collaborate on the data finding, tracking, and analysis process with each other and with our GrowthFactor Agent to move faster and win deals. We augment our customer’s teams with a best-in-class Forward-Deployed Data Scientist team, called our Labs team, which partners with our customers to build unbeatable data insights and forecasts.

There is no home for commercial real estate. When we win, GrowthFactor will be the place all commercial real estate happens.
