I ate a big breakfast. So if my scans are off, don’t sweat it, I tell myself. And this was immediately following a long, unhealthy weekend (a friend’s wedding). All of the excuses of the first world were available to me as I walked up the stairs in The Assembly, a women’s club in San Francisco, one that looks like it was once a place of worship but now hosts accomplished-looking laptop-clackers and has bottles of sweet-smelling face mist in the bathroom. This is where I would get my body shape and fat percentage measured by a company that has named itself Naked.

Naked Labs makes a full-length mirror lined with 3-D cameras that capture a 360-degree image of your body. There’s also a weight scale involved, something that the company’s cofounder and CEO, Farhad Farahbakhshian, calls the turntable (more on that later). Farahbakhshian, a former electrical engineer and certified Spin instructor, first introduced the Naked 3-D Fitness Tracker to the world two years ago and crowdfunded it through the company’s website. The initial launch was set for March 2017. Naked Labs missed that deadline by a great many months.

Now, several product iterations and more than $14 million in funding later, the Naked 3-D Fitness Tracker is shipping. The company’s funding round was led by Founders Fund, Peter Thiel’s firm, and included NEA and Lumia Capital. (Cyan Banister, another partner at Founders Fund, personally invested in Naked Labs.) “The product took much more capital, manpower, and time than we expected,” Farahbakhshian told me over the phone the day before I got my scans done. During that time, Intel’s RealSense cameras—which is what the Naked scanner relies on—were upgraded, which put the company in a holding pattern until it could build the product with the latest tech, he said.

The scanner now costs $1,395, a significant hike from the $499 the company listed it for at launch. But Naked Labs is wagering that (a) fitness freaks, (b) people looking for motivation to lose weight, and (c) customers who aren’t unnerved by daily 3-D scans of themselves will all pay to own the product. Its target customer has changed, Farahbakhshian said, from “people with a six-pack who want to get an eight-pack to people in the earlier stages of their fitness journey … Sure, there are power athletes who want to get that extra 1 percent, but we also see people who have felt powerless about their bodies for most of their lives.”

Farahbakhshian and Sam Winter, Naked Labs’ head research scientist, were waiting for me when I entered the room at the Assembly. Winter is a cognitive neuroscientist and sometimes triathlete who took the lead during the demo. She and Farahbakhshian suggested, both over the phone and in person, that the scan would work better if I stripped down to my underwear. I wore stretch pants and a long-sleeved shirt.

The mirror is nicely constructed—something I never thought I’d say about a mirror but feel obligated to note since it costs $1,395. It weighs 30 pounds, and with its frame measures 62.5 inches high and 12 inches wide. The back panel is plastic; its sides are powder-coated extruded aluminum. Three Intel RealSense 410 series cameras line the left side of the frame, along with a laser pointer (A laser pointer! In a mirror!) and a round indicator light.

Without warning, it began to spin me around, like a cat on a Roomba.

Winter fired up the 3-D Fitness Scanner, and the laser pointer shined a light onto the hardwood floor. She pulled the scale out from under the mirror and lined up the center of the scale with the laser's red dot. The scale, which charges via USB-C, is a disc of injection-molded plastic with a glass top. It wobbled slightly on the smooth hardwood when I stepped on it and widened my stance. The company says it also works well on carpet.
