Giving surgeons a real-time sense of where they are - the way the body already knows.
Gabriel Jones runs a company named after a sense most people never think about. Proprioception is the body's quiet talent for knowing where its own limbs are without looking - the reason you can touch your nose with your eyes closed. Jones, the co-founder and chief executive of Proprio, spends his days trying to give surgeons a version of that same instinct, built from cameras, artificial intelligence, and a great deal of math.
Proprio, based in Seattle, builds surgical navigation technology. Its flagship platform, Paradigm, received FDA 510(k) clearance in April 2023 for use in spine procedures. The system uses light-field imaging - arrays of cameras capturing an operating field from many angles at once - combined with real-time AI to reconstruct a live, three-dimensional model of a patient's anatomy. Instead of pausing to interpret a static X-ray printout, a surgeon can work against a moving, updating picture of what is actually in front of them.
Jones likes to reach for a familiar comparison. Traditional guidance, he says, is like navigating with a printed map. Paradigm is meant to feel like live GPS. The difference is not cosmetic. In spine surgery, alignment matters at the level of millimeters, and Jones has pointed out that spinal corrections currently succeed only around a third of the time. He co-founded the company to move that number.
That question is not marketing gloss. It is the thread that runs through an unusually winding career. Jones studied engineering at the University of Washington through a Japan-based program taught by Japanese professors, covering mechanical and electrical engineering alongside computer science. He then went to work at Taisei, one of Asia's largest civil engineering firms, where he was the only non-Japanese employee - an early lesson in operating far outside a comfort zone.
From construction he moved to governance, studying legal systems in Washington, DC, and then to Wall Street, where he worked on large-scale mergers and acquisitions for clients that included AT&T and Google. It was lucrative, high-stakes work. It was also, by his own telling, not quite enough. He wanted the ledger to balance on both sides - financial and human.
So he came back to Seattle and joined the orbit of the Bill & Melinda Gates Foundation, working on global health initiatives and, at times, directly with Bill Gates on special projects evaluating emerging technology. That period seems to have crystallized the ambition that became Proprio: take the frontier tools he had been assessing for others and point them at a problem where the stakes are measured in patient outcomes.
Jones did not do it alone. In 2016 he co-founded Proprio with three people who supplied the domains he lacked: Dr. Samuel Browd, a neurosurgeon at Seattle Children's Hospital who understood the operating room from the inside; Joshua Smith, a University of Washington professor working at the edge of sensing and robotics; and James Youngquist, a computer vision specialist. The name came later, but it fit - a company trying to give machines a spatial sense that the body performs effortlessly.
The early money was scarce and personal. Jones has said he self-funded with his own savings before a $50,000 grant unlocked a $1.6 million pre-seed round. The Series A landed during the first wave of the COVID-19 pandemic, which he now describes, half-joking, as raising money from his kitchen. A Series B of $43 million followed in 2023, bringing Proprio's reported total funding to roughly $78 million and its headcount to around 70.
Jones is candid about the shape of the market he is building into. The Pacific Northwest, he notes, has no anchor medtech company on the scale of an Intuitive Surgical or a Medtronic. Rather than treat that as a reason to relocate, he has decided to be part of the fix - to seed a regional ecosystem himself, betting that small, distributed teams with access to global talent can produce outsized results. It is a founder's version of the do-well-and-do-good question applied to a whole city.
He is also unusually direct about fundraising, a subject where founders often trade in euphemism. His advice tends toward the blunt. Add fifty percent to any timeline you believe: if you think six months, plan for nine at minimum. Be selective about who you pitch - do not, he says, spend time with investors who have not written a check in your space in more than two years. And understand the person across the table, because venture capitalists answer to their own investors and are rarely as secure as they appear.
Inside the company, Jones leans on what he calls a 10-second rule. A win gets ten seconds of acknowledgment; so does a failure. Then the team refocuses on the larger objective. The point is not to suppress emotion but to keep a small organization moving at speed, unwilling to be either intoxicated by good news or paralyzed by bad. He treats communication and public relations as part of leadership rather than an afterthought, arguing that clear messaging attracts strong talent and sharpens the feedback the market sends back.
People who have interviewed him describe someone captivating and, at the same time, remarkably down-to-earth - driven by what one profile called an unquenchable curiosity. He casts himself as an active player rather than a spectator, someone who wants to stay at the front edge of what technology can do. The advisory bench he has assembled reflects that pull toward depth: it includes former Globus Medical chief executive Dave Demski and Takeo Kanade, one of the most cited computer vision researchers alive.
What Jones is chasing next is conversion - turning years of market-building and technical progress into measurable improvements in surgery itself. The platform is cleared. The team is in place. The metaphor at the heart of the company still holds: the body knows where it is without being told, and Jones wants the operating room to work the same way. If Proprio succeeds, the surgeons using it may stop noticing the technology at all, the way you never think about how you find your own nose in the dark.
That would suit him. For a founder who keeps asking whether it is possible to do well and do good, the best outcome is not a product people marvel at. It is one that quietly makes the work safer and then gets out of the way.
Just like navigating with real-time GPS rather than a printed map.
Is it possible to do well and do good?
Your products have to make other products sing.
If you're doing interesting, challenging things, then you're not fully prepared for the next job. The same is true for financing.
He is the co-founder and CEO of Proprio, a Seattle medtech company building AI-powered surgical navigation technology.
Proprio is a medtech company whose FDA-cleared Paradigm platform combines light-field imaging, real-time AI, and 3D visualization to guide spine surgery.
Proprio was founded in 2016 by Gabriel Jones, neurosurgeon Dr. Samuel Browd, University of Washington professor Joshua Smith, and computer vision specialist James Youngquist.
He studied engineering in a Japan-based program, worked at the civil engineering firm Taisei, ran Wall Street M&A, and worked with the Bill & Melinda Gates Foundation on global health.
Yes. Proprio raised a $43M Series B in 2023, bringing reported total funding to roughly $78M.
