Haniff Brown likes to say that some years feel slow, and others feel like they happen in a week. This has been one of those weeks-that-feel-like-years phases for FIT:MATCH.ai. When sat down for an interview with Refresh Miami, Brown joked about fighting off a cold amidst the Art Week madness, but his energy gave away what was really going on: the company has stepped into a faster phase of growth.

That shift arrived with QuadraScan, a technology Brown described as a clear turning point. With nothing more than four standard photos taken on any device, FIT:MATCH can now generate a hyperrealistic digital twin in seconds. The magic happens inside a giant neural network running on high-powered NVIDIA chips. It’s the kind of leap that once required expensive hardware and controlled environments. Now it works from a kid’s Android phone or a patient’s living room.

It also meant rebuilding FIT:MATCH from the inside out. The team had to rework their full infrastructure so this process could run fast enough for real clients in healthcare, sports, and retail. But the payoff has been immediate. Through computer vision landmarks, the system instantly extracts more than 40 body data points, then layers in estimates on lean mass, fat mass, and bone metrics.

The first time he explained it, Brown paused and summed it up in a single line: “Our goal is to generate what we call the ChatGPT of the human body.”

That idea helps explain why the company’s growth has jumped sharply. Brown said FIT:MATCH has expanded its client base by roughly 300% in the past year, driven almost entirely by this new model. Sports teams now use it to scout kids as young as 13. A baseball scout no longer has to guess whether a young pitcher will top out at five-nine or grow into a six-two frame. The tech gives them a projection backed by data. Major League Soccer is next in line, with Brown traveling to Atlanta and Arizona for upcoming work with youth development programs.

Retail buyers have also leaned in. Instead of asking whether someone should order a medium shirt online, FIT:MATCH helps designers understand what a medium should even be. Brands have long relied on rigid avatar libraries in their 3D design tools. FIT:MATCH now gives them flexible, population-level inputs in minutes, not weeks. Cost drops. Accuracy rises. And shoppers get clothing that actually fits.

Healthcare, though, might be where the biggest shift happens. FIT:MATCH is used by GLP-1 programs, bariatric groups, and plastic surgeons to monitor patients from home. One Miami surgeon, known for a large out-of-state clientele, now has a clear read on patients long after they’ve flown home. Brown pulled up before-and-after images of real cases. With four photos, the model measures changes with precision; every change in fat distribution or muscle tone is quantified.

The health side is also where Brown’s own vision seems to be headed. “I actually think this can help save lives,” he said. One hospital partner is using it to monitor certain neuro conditions from home, where early detection can change outcomes. What began as a tool aimed at improving shopping has turned into a platform with medical value.

All of this has pushed the team to around 30 employees, with a growing South Florida presence. FIT:MATCH also raised an extension to its Series A to support expansion into sports science and digital health. Brown expects another raise within the next year. To date, the company has secured $18 million.

“I like to tell people that the worst version of the model is the one being used today,” Brown asserted. If that’s true, the next versions could open a much bigger window into how our bodies work.
