Mindeo Turns Brain Fitness Into a Green Lake Workout

A 2016 fall led to this Green Lake studio

Xenia Kachur was rock climbing in 2016 when a fall left her with a concussion that would not clear.

For months she could not run, think clearly, sleep through a night, or hold a conversation with the people closest to her. "It flipped my life upside down," she says of that stretch. Kachur, a biomedical engineer, wanted something else.

"I wanted to treat the root issue," she says, and that search became Mindeo, the brain fitness studio she now runs out of 7301 5th Ave NE in Green Lake. Her training was in engineering, not medicine, and the studio she built reflects it: hardware and repetition rather than a pill or a worksheet.

Mindeo used to be called REWIRE

The studio did not start as Mindeo.

Kachur and a clinician identified in early coverage only as Doctor West, who had treated her own injury, opened a company called REWIRE in Green Lake in July 2020, four years after her accident. "My goal is to show people that they can have a higher baseline in their quality of life," the founder told Business Impact NW. According to a Yelp listing, REWIRE's original address on Woodlawn Ave NE is now marked closed.

REWIRE is now REWIRE Labs Inc, doing business as Mindeo in the United States, and Rewire Labs Canada Inc, doing business as Mindeo north of the border. The name changed. The legal entity and the underlying program did not. Luke Starbuck, co-founder, carried over as Mindeo's chief operating officer. In May 2024, he and Kachur published "Mindfire: The Surprising Science of How Brain Inflammation Impacts Mental Health and What You Can Do About It." Mindeo today operates two locations in total, this one in Green Lake and a second studio in North Vancouver, British Columbia.

Inside a session at the studio

This is not a gym workout.

A client pedals a recumbent stepper with compression cuffs on both arms and legs, spends time under a red and near-infrared light bed, and plays a Tetris-style game through handle-based controls while a heart rate monitor tracks the load and the seat and palms cool. "Our approach magnifies natural processes," Kachur says of the combination, branded BIITT, short for Brain-Integrated Interval Training Technology, and delivered in what the studio calls SynapFit sessions.

Clients come in two or three times a week, for roughly 40 to 45 minutes at a stretch, depending on which of the studio's own pages is doing the describing. Seattle Met's own walkthrough matched the studio's description device for device, down to the music chosen to fit the session.

Who actually walks in the door

Most of the people walking into Mindeo are not gym members looking for a new machine.

By the studio's own count, 68 percent of clients are not exercisers at all. Ages run from 25 to 85. The studio's own pitch draws the line explicitly. It describes itself as brain fitness "without joining a gym." That line does the real work of positioning. Mindeo is not competing with the gym down the street.

It is arguing that brain fitness is its own category, one a person can walk into without ever setting foot on a gym floor. For a Seattle office worker weighing a lunchtime workout against a lunchtime nap, the actual pitch is neither: a stationary bike playing a video game.

How to start

Programs at Mindeo start at $150 a week.

Prospective clients get a free 15-minute phone consultation and a free, in-person Brain Fitness Orientation visit, then a phone number: (360) 670-0248, the Green Lake studio, for everything else.

A four-week guarantee

Mindeo offers what it calls a Cognitive Confidence Guarantee.

The homepage and the Get Started page put it the same way: "Attend all your SynapFit sessions in the first 4 weeks and if you decide it's not for you, let us know. We'll cancel the rest of your program commitment and we will give you 2 extra weeks of maintenance sessions on us." Widen the search past Green Lake and the closest match to Mindeo in Seattle is not a gym at all.

The Psy Center runs Cogmed Working Memory Training in the city, but it is built and marketed as clinical cognitive rehabilitation, not a paid session a person walks in and books. Consumer brain-training apps like Lumosity and BrainHQ, and wearables like Muse and Mendi, put the training in a person's own hands, with no staff and no studio involved. A search across Seattle's fitness and wellness listings did not turn up another in-person, coach-led studio pairing a cardio machine with a video game and calling the result brain fitness. Kachur went looking for a treatment like this in 2016 and did not find one. Ten years later, in Green Lake, the search still comes up empty.
