Oliver Wenner has a new job title. On June 25, 2026, Premarket announced it had acquired Maklare AI, the New York artificial intelligence company he co-founded and ran as CEO, and that he would join Premarket as chief operating officer.
Premarket runs an agent-only platform that gathers private real estate listings from different brokerages into one searchable network. Maklare AI works on the other half of the market, structuring demand-side data in residential real estate.
The gap Maklare was built to close
Listings are visible. Demand is not. Premarket’s announcement says residential real estate has long worked with near-complete opacity on buyer demand, leaning on anecdotal agent intelligence and historical transaction data for pricing and timing decisions. Maklare was founded on the idea that this is not inevitable, and built its own AI infrastructure to turn siloed, unstructured demand data into signals about buyer behavior, preferences and intent. Those signals, the company says, usually vanish the moment a conversation ends.
Premarket describes the other side of the problem as fragmentation. As brokerages and portals move inventory out of shared listing layers and into closed networks, agents, buyers and sellers all lose part of the picture. Premarket was built as a shared layer that pulls siloed private inventory and buyer demand together, so agents can see the market before it goes public.
What the combined company claims
Put Maklare’s tools inside Premarket, and the company says the result is a forward-looking demand intelligence platform, the first of its kind in residential real estate. It would draw on $4 billion in active New York City private inventory and thousands of active buyers, using live, structured data from both sides of the private market.
“Real estate listing data is rapidly fragmenting,” said Brett Helberg, founder and CEO of Premarket. “Premarket exists to rebuild that shared infrastructure, but on better terms for every agent, brokerage, and their clients.” He called the deal “a meaningful acceleration of everything we’re building,” and said it lets the company work on supply and demand at once.
Wenner framed it as the same problem seen from two directions. “Real estate has always been a supply-side industry,” he said. “The demand side has operated in complete opacity. Agents know their own clients, but the market has no structured view of aggregate demand, directional intent, or forward-looking buyer signals.” Inside Premarket, with real inventory and real buyers at scale, he said, “we can build the demand intelligence layer this market has never had.”
Premarket is based in New York City and is expanding nationally. Agents who want access can apply at premarket.nyc. Financial terms of the acquisition were not given in the announcement.
