FullStack Modular began with a 32-story experiment that ran late, went to court, and still changed what a factory-built building could be. Now the company is betting that the lesson was never “build boxes faster” - it was “redesign the whole sequence.”
Conrad Prebys built a San Diego rental business whose wealth reached classrooms, concert halls and medical research. The sale of his apartment portfolio exposed a harder question: what happens to the people still living inside it?
A Santa Monica design workshop moves between apartment buildings, rain barrels, and homes for living alone together. The common question: what should we share, and what should we keep to ourselves?
Alex Rodriguez built his investment business around apartment buildings, then added startups, sports teams and a media operation. Its most revealing deals show both the value of a famous name and the limits of one.
The eight-person Miami operator did not invent roommates. It made the arrangement feel less like a compromise - then built the economics around the parking spaces it never had to pour.
Sustainable Living Innovations spent 16 years turning apartment towers into a kit of parts. Its Seattle buildings prove the hardware works - and its bruising flagship reveals why fixing construction takes more than a factory.
The Nashville firm turned recession-era opportunism into a vertically integrated housing business. Its next test is harder: making public-private affordability work at city-shaping scale.
From a Logan headquarters, Wasatch Group buys, builds, finances and manages housing across the West. Its advantage is less a single breakthrough than control of nearly every handoff.
IMT Residential grew from 62 apartments and one employee into a nine-state operator by treating the unglamorous details - maintenance calls, team training and online reviews - as the product. Its new Citrus Commons development shows what happens when that operating discipline meets architecture.
RealPage began by putting apartment ledgers online. Now its software reaches from the first leasing inquiry to the final rent payment - and its next act is an AI workforce built for the unglamorous machinery of rental housing.
Most steel companies stop at the loading dock. Zekelman follows the material into warehouses, job sites and even finished apartments - a 149-year industrial lineage betting that control of the chain can make American construction faster and more predictable.
EliseAI is a New York-based artificial intelligence company that builds conversational and agentic AI to automate the routine, high-volume communication work of two administratively heavy industries: rental housing and healthcare. Its assistants answer calls, emails, texts and chats around the clock - scheduling tours, handling maintenance and renewals, collecting rent, and booking patient appointments - so property and clinic teams can focus on people rather than paperwork. Founded in 2017 as MeetElise, the company crossed $100M in annual recurring revenue, serves roughly 70% of the 50 largest U.S. rental housing operators, and reached a $2.2 billion valuation with its 2025 Series E led by Andreessen Horowitz.
Grotto AI builds an AI coaching platform for multifamily leasing teams, listening in on calls and tours and nudging agents in real time toward the behaviors - curiosity, rapport, a well-timed laugh - that its data shows actually close leases. Founded in 2025 by Nick Deveau and Ben Epstein, veterans of the AI-in-insurance startup EvolutionIQ, the company raised a $10 million seed round led by ICONIQ Capital in February 2026 and already runs on portfolios for operators like Weidner Apartment Homes.
Tailos (formerly Maidbot) is an Austin, Texas robotics company building AI-powered autonomous cleaning robots for commercial spaces. Its flagship product, Rosie, is a self-navigating commercial robot vacuum that uses self-driving-car technology - LiDAR, 3D depth cameras, and proprietary SLAM - to clean hotels, multifamily buildings, and senior-living facilities with no pre-mapping or setup. The company's pitch is plain: automate the most repetitive, physically punishing parts of cleaning so housekeepers can do higher-value work, with operators saving roughly 54 minutes per labor hour.
Factory OS is a Vallejo, California modular-housing manufacturer that builds wood-frame multifamily apartments inside a former Mare Island Navy shipyard. Co-founded in 2017 by affordable-housing veteran Rick Holliday and contractor Larry Pace, the company treats apartments like cars: rolling them down an assembly line with union labor, cutting build times by ~40% and costs by 20–40% compared with conventional construction.
