RentSpree Beat Rental Paperwork. Now It Wants to Run the Whole House.
A reusable application got RentSpree through the door. Four million users later, the company is turning tenant screening into a wider play for rent payments, landlord banking, and the rental layer inside America’s MLS systems.
RealPact
RealPact is a Y Combinator (S26) startup building an AI-native operating system for real estate brokerages. Its voice-powered AI agents take a single property address and automatically pull deeds, tax records, permits, parcel data and MLS listings, then draft and auto-fill contracts, organize documents and track deadlines. Founded by Dartmouth graduates Ranvir Deshmukh and Erik Peterson, the company aims to cut the roughly 165 hours a year agents spend on paperwork down to minutes, and is already live with brokerages including Four Seasons Sotheby's International Realty, Black House Real Estate and Next Homes.
Asteroom
Asteroom turns an ordinary smartphone into a professional 3D virtual tour and property data collection tool. Founded in 2018 by ex-Facebook and Microsoft engineers, the company sells an inexpensive Pano Kit tripod plus an app that lets real estate agents, appraisers, and property managers capture immersive 3D tours, floor plans, and measurements without a $3,000 camera. It has since become a property data collection provider integrated with Fannie Mae, Freddie Mac, Zillow, and Realtor.com, powering appraisal modernization workflows through a national network of trained data collectors.
Indigo
Indigo is an AI-powered home transaction platform that reworks the messiest part of buying and selling a house: the offer and the paperwork behind it. Built by the founding team behind Ribbon, the New York startup replaces the email-and-PDF scramble with real-time offer dashboards, AI-generated and compliant contracts, and shared deal rooms for agents, buyers and sellers. It raised an $8 million seed round in January 2025 and says it topped 20% of home offers in its first markets within three months of launch.
Michael Martin
Michael Martin is the Co-Founder and CEO of Sidekick, a generative AI assistant purpose-built for real estate agents and brokerages. A Dartmouth-educated executive with a career spanning investment banking at Deutsche Bank and Apollo Global Management, digital agency leadership at Code and Theory, and proptech entrepreneurship, Martin co-founded Avenue 8 in 2020 as a tech-enabled mobile-first brokerage. When Sidekick's AI tooling proved more compelling than the brokerage itself, he made the bold call to shut down the brokerage entirely and go all-in on the software platform. Sidekick has raised $18M in funding, won back-to-back Webby Awards in 2024, and secured MLS partnerships covering over 120,000 real estate agents across the US.
