Homes.com
The real estate portal game has always carried a quiet tension. Consumers believe they are searching for homes. Agents understand they are often the commodity being routed, resold, and repackaged. Trust erodes in the background. Homes.com, operating under CoStar Group, stepped into that gap with a different posture, one grounded in alignment rather than arbitrage. The thesis is clean and difficult at scale. Put the listing agent back at the center and let everything else orbit with intent.
That conviction traces directly to Andrew C. Florance, Founder and CEO of CoStar Group, who has spent decades turning real estate data into leverage that compounds. When CoStar acquired Homes.com in 2021, it was not opportunistic. It was deliberate. A capitalized, data-rich public company moving into residential with a clear critique of the status quo and the infrastructure to do something about it. No rerouting games. No hidden incentives. Just a tighter connection between buyer intent and agent expertise, executed with the discipline of a company that has built category leaders before.
The product mirrors that thinking with precision. Homes.com delivers millions of listings layered with neighborhood intelligence, school data, and high fidelity media, all powered by CoStar’s research engine. But the real shift is mechanical. The listing agent is visible. The lead is not diverted. It lands where it belongs. Andy Stearns, SVP of Homes.com Sales, is scaling that promise into a membership model where agents are not renting exposure but establishing durable presence. That subtle shift in economics carries weight across the startup ecosystem, where business model alignment often defines long term winners more than feature sets.
Then the tempo changes. February 2026 introduces Homes AI, and now the interface evolves from search bar to dialogue. Led by Livia Sponseller, SVP of Product, alongside Andy Ventura, VP of Enterprise Solution Architecture, the platform moves into real time guidance. Built on Microsoft Azure and trained on CoStar’s proprietary dataset, it listens, adapts, and responds with context. Not a static list. A dynamic exchange shaped by behavior, preference, and intent. This is where infrastructure meets experience, and where data density starts to feel like intuition.
Scale is already in motion. The Homes.com Network is drawing over 100M monthly visitors, and CoStar is explicit about its ambition to grow this into a $1B business line. The edge is not just reach. It is alignment at scale. When agents win more listings through the platform, the system reinforces itself. That feedback loop is the kind of signal operators across the startup ecosystem recognize immediately.
For builders, this is a rare configuration. A high velocity product inside a company that understands how to build, scale, and defend marketplaces. Engineers, product leaders, AI specialists, and operators are stepping into an environment where the inputs are real and the stakes are measurable. The door is open at their careers page.
Watch closely. When incentives realign and data compounds, categories do not just evolve. They reorganize in plain sight, and the startup ecosystem tends to follow the gravity.
