Making it easier to find an apartment is the goal of the Rentgrata app. It connects apartment hunters with their would-be neighbors, letting those on the housing hunt chat with tenants in the buildings they're considering. For people seeking an apartment the Rentgrata app lets them find answers to questions that might not be available online. For tenants the reason to use the app is to cash in on their building's referral bonus.
Referral bonuses vary by building, but most come out to a couple hundred dollars and are given to both the person moving in and the person who referred them. The Rentgrata app sets up the referral over the app making it easier to cash in. The Rentgrata app currently operates solely in Chicago but there are plans to launch more cities, and an Android app, down the road.
