For thirty years, Mike Simon watched the real estate services industry buy data platforms, load them with historical MLS transactions, and then mostly ignore them. The problem was not the data. It was that data, on its own, does not tell a professional what to do next.
“Data is the raw information,” says Simon, CEO of AgentBrief, a real-time MLS intelligence platform. “A signal is the specific thing that tells you to act right now.” That distinction is at the heart of what Simon argues the industry has missed since the first dot-com boom made data accessible.
The earlier platforms were built around a workflow that rarely exists in practice: a professional sitting down with a dashboard, reviewing a week's activity, and executing outreach. Simon has spent enough time with actual title reps and loan officers to know that does not happen. “People buy technology thinking it will solve all their problems,” he says. “Then it becomes too cumbersome to use. They get discouraged. And the problem it was supposed to solve does not go away.”
Timing is central to Simon's argument. A notification about a new listing delivered four days after it goes live is nearly worthless. “If you don’t find out about things first, you really are last,” he says. Real estate agents make referral decisions in motion, while transactions are moving. By the time most professionals have that information, the agent has already heard from someone else.
AgentBrief monitors MLS activity every hour. When an agent lists a property, changes a price, or schedules an open house, the professional gets a push notification on their phone at the exact moment the opportunity opens. The platform also solves a related problem: knowing whether an agent is worth pursuing. Simon describes professionals spending months cultivating a relationship with an agent who claims a high transaction volume, only to find out later it is not supported. “You can literally turn your back, type in an agent’s name on your phone, and see whether they’re actually doing business,” he says.
AgentBrief is organized around five functions: find, follow, monitor, alert, and engage. Most data platforms stop at the first one, leaving the user to figure out the rest. That creates friction points where professionals drop off. “We made data accessible, gave it good timing, and gave people a tool they could actually use,” Simon says. “If you go in with something so convoluted that people get discouraged, they stop using it.”
The professionals who have moved earliest on real-time MLS signal are building referral relationships with the most active agents before those agents have a preferred vendor. That structural advantage compounds, and it is not available to those who wait.
