BIO_SOLE · OUR TEAM

The people who measure it.

Somebody has to answer for a claim about your body.

Bio_Sole makes an insole that fits inside an ordinary shoe. It recognizes you by the way you walk, and it measures how you move. That is a serious thing to build, and a serious thing to be trusted with. So this page is simply who builds it: name, role, and the whole career behind it. Press the plus on any name to read the long version.

WHERE THE WORK COMES FROM

So here is who builds it.

The mathematics comes out of Montreal. The centre of gravity is Ottawa, where the company is run, the communications are written, and the work itself is stored in a Canadian data centre we know personally. The Vice-Chairman works from the UK, and the rest of the team writes in from Texas, California, Connecticut, Pennsylvania and Michigan. Engineers with 30 years on hardware that has to be trusted, scientists who wrote the models before the sensors existed, an inventor who started in 2009 and still draws the next version himself, and advisors whose job is to tell us when we are wrong.

Leadership

The people who answer for the company, its money, and where it goes next.

  • Todd Gray, founder and CEO of Bio_Sole

    Todd Gray

    Founder and CEO

    Todd Gray invented the insole that knows who you are.

    Read the full biography of Todd Gray

    Ottawa, Ontario

    Todd Gray founded Bio_Sole, and he invented the thing it makes. He began the work in 2009. Almost twenty years later, he is still the person who draws the next version.

    The idea began with a simple observation. Your walk belongs to you alone. Todd set out to build a device that could read it. In 2014 he ran the first prototype program in New Brunswick, which is where the science of how the body carries weight stopped being a theory here and started being measured. He was also writing machine learning into the design years before that was a common thing to do. He is often the first to say he was early rather than right.

    Todd built the company structure as well as the product. Autonomous ID Corporation in Canada holds the inventions. Bio_Sole International Group runs the business. Atlantic Footcare, a manufacturer with forty years of history, makes the insoles in the United States. He still works in the hardware himself. When a sensor needed replacing, he designed, built and delivered a new one in thirty days.

    He is at his desk by five in the morning. He has a thirteen year old son, and he quietly pays for local hockey sponsorship out of his own pocket. Ask him what the company is for and the answer is short: autonomy in a connected world, one step at a time.

    He also has a sentence he returns to whenever the science gets complicated. The body doesn't lie.

    Autonomy in a connected world, one step at a time.

    Daniel Brown

    Chief Financial Officer

    Daniel Brown runs the money and the discipline.

    Read the full biography of Daniel Brown

    United States

    Daniel Brown is the Chief Financial Officer of Bio_Sole. He has been with the company through every stage of its growth, and he speaks with Todd Gray four or five times a day.

    Dan brought Bio_Sole its factory. He completed the acquisition of Atlantic Footcare, a Rhode Island manufacturer with forty years of history, which now makes the company's insoles in the United States. It moved Bio_Sole from a company with a design to a company that can build.

    He runs finance on his own. Banking, planning and investor relationships all sit with him. His working method is patient sequencing: he does not build something until somebody has asked for it, which is a useful counterweight in a company founded by an inventor. Todd calls the two of them yin and yang.

    He is also the clearest explainer in the building. No two people walk the same way, he says. I can't get in someone else's shoes and make them think I'm that person. It's a biometric signature, and that leads to all sorts of applications.

    He is careful about how the company gets there. We're not going to cut any corners in making sure we get to the point where we can show and tell and let the world know what we're doing.

    No two people walk the same way. It's a biometric signature, and that leads to all sorts of applications.
  • Todd Basche

    Todd Basche

    Chief Product Officer

    Todd Basche has taken seven startups from garage to market.

    Read the full biography of Todd Basche

    United States

    Todd Basche is the Chief Product Officer of Bio_Sole. He joined in 2025, and his job is to keep a company full of possibilities pointed at one market at a time.

    He has done this before, roughly seven times. He has worked in startups at every stage, from two people in a garage to taking a company public. Before that he was a vice president at Apple, where he worked directly with Steve Jobs. That mix of consumer product instinct and hard commercial sequencing is unusual, and Bio_Sole needs both.

    He also teaches. At the Stanford Graduate School of Business he runs sessions in the Lean LaunchPad program, which trains founders to test a business model before they build anything. His students hear the same thing his colleagues do: startups don't fail because they focused too tightly, they fail because they're all over the map.

    At Bio_Sole he owns product strategy, market selection and go to market planning, and he is hiring the company's first product manager. He wants plans written at what he calls the Goldilocks level - not ten miles up, and not down in the weeds.

    He is generous with structure, and modest about how much of it is needed. A teaspoon of structure helps enormously.

    Startups don't fail because they focused too tightly. They fail because they're all over the map.
  • Dr. Bernard Grisoni

    Dr. Bernard Grisoni

    Chief Product Design and Manufacturing Officer

    Dr. Bernard Grisoni has decades in foot care and materials science behind him.

    Read the full biography of Dr. Bernard Grisoni

    Memphis, Tennessee

    Dr. Bernard Grisoni is Chief Product Design and Manufacturing Officer at Bio_Sole. He has held the role since 2014. His job is to turn a good idea into something a factory can make.

    He has done that for forty years, in hard categories. He began at Dow Corning in France, working on silicone gels and foams. He moved to Allergan, where he developed a new silicone for lenses, and then to Wright Medical. In every one of those roles the same discipline applied: a material has to behave the same way on the ten thousandth unit as it did on the first.

    Then came sixteen years at Merck, as a principal scientist on Dr. Scholl's. He led the development of sixteen new products. The work was human testing, measuring feet, and modelling how they carry load. It is hard to imagine a better preparation for this company.

    He founded his own product development firm, BioGeneration, in 1997. He holds a PhD in industrial engineering, an MBA from Pepperdine University, a master's in polymer engineering and a bachelor's in materials science.

    He teaches as well. Since 2019 he has been an adjunct professor at the University of Memphis, covering biomaterials and design. He speaks French and English as a native. And he writes mystery novels. There are three so far.

Technology and Science

They build the device and the mathematics behind it. Their work has to prove itself, every time.

  • Tony Robinson

    Tony Robinson

    Chief Technology Officer

    Tony Robinson has spent thirty years building hardware that has to be trusted.

    Read the full biography of Tony Robinson

    United States

    Tony Robinson leads technology at Bio_Sole. He has been with the company for more than twelve years, which makes him one of the few people who has seen every version of the idea.

    His career is thirty years of hardware that has to be trusted. He has worked in cybersecurity since 1990. He has been a chief technology officer before, in Reston, Virginia. He has worked with General Motors and OnStar on vehicle security, and he built biometric hardware for use in the field. Early on, he helped port a six and a half million line engineering codebase onto the IBM PC. He once managed a thirty six million dollar security budget and landed within half a percent of the estimate.

    At Bio_Sole he owns the electronics, the security strategy and the engineering side of manufacturing. The current board program began about three years ago and has been through seven generations. Version 7.6 is the one going to the factory floor.

    He is clear about what the company actually is. We are not really an insole company, he says. We are a data company, and data is king. And he is clear about why security comes first: he wants Bio_Sole in the news for being the most innovative and most secure product in its field, and for nothing else.

    He half jokes that he is only thirty eight, despite a full head of grey hair. He keeps three rescue dogs, maintains his own land, and is half Italian. His father was an American serviceman who met his mother near Venice in the 1940s.

    We are not really an insole company. We are a data company, and data is king.
  • Thomas Elliott

    Thomas Elliott

    Head of Data and AI

    Thomas Elliott makes the platform answerable.

    Read the full biography of Thomas Elliott

    Philadelphia, Pennsylvania

    Thomas Elliott leads data and artificial intelligence at Bio_Sole. He joined near the end of 2025, and he owns the part of the company that has to be able to prove itself.

    His work is the path a step takes. Movement is measured, classified, and turned into something the platform can act on. What makes it unusual is the record kept alongside it. Every model is versioned. Every result is logged. Years later the company can still show which version of which model read a person's walk, and on which day.

    That matters more than it sounds. The entire structure of replayability, of explainability, of interpretability, of what it is that we built, it all comes from a very sound, versioned, explainable infrastructure, he says. Without it, an insight is an opinion. With it, an insight is a record.

    He is careful about the language too. When the platform reports that a walk has changed, he wants that treated as an observation supported by evidence, and never as a diagnosis. He is equally candid about scope. It is a novel biometric. It doesn't mean that it's not a usable biometric. It just means it has a defined place.

    He works from Philadelphia, with a stretch of interstate outside the window and Toronto somewhere in his past. He has spent two years in an AI practitioners' circle, joins a quarterly roundtable in New York, and speaks publicly on AI governance. He is a generous introducer, and drier than he lets on.

    It all comes from a very sound, versioned, explainable infrastructure.

    Dr. Vladimir Polotski

    Principal Scientist, Algorithms

    Dr. Vladimir Polotski wrote the mathematics under the product.

    Read the full biography of Dr. Vladimir Polotski

    Ottawa and Montreal

    Dr. Vladimir Polotski leads algorithm development at Bio_Sole. Apart from the founder, he has been here the longest.

    He builds the mathematics that turns a sensor reading into a measurement of how somebody walks. He started before the sensors existed. We started at the time when inertial sensors were not there yet, he says, which is a quiet way of describing a very long run at a hard problem. He holds a PhD in mechanics and control, a distinct discipline in the Russian academic system. He calls his working life applied mathematics, never pure.

    He works with Dr. Vaibhav Shah on how prototypes are validated and calibrated before they are made at scale. He is also the most careful voice in the building on the limits of artificial intelligence, and he happily defers on it to colleagues who know it better.

    What he worries about is memory. The expertise is sitting in the person's mind, he says, and when that person is gone the knowledge goes too. His conclusion is short, and it has shaped how Bio_Sole documents its science. It has to be system, not people.

    He splits his time between Ottawa and Montreal, with a chalet near Lachute. He grew up around Côte Saint-Luc and Notre-Dame-de-Grâce. He is self deprecating about his English, which is unnecessary, and he believes in the old scientific habit of meeting regularly and in person. Nobody in the tradition he came from thought that was a waste of time.

    It has to be system, not people.
  • Dr. Vaibhav Shah, who leads biomechanics and research at Bio_Sole

    Dr. Vaibhav Shah

    Biomechanics and Research

    Dr. Vaibhav Shah holds the doctorate in biomechanics that the science rests on.

    Read the full biography of Dr. Vaibhav Shah

    Montreal, Quebec

    Dr. Vaibhav Shah leads biomechanics and research at Bio_Sole. He holds a PhD in biomechanics, and he is affiliated with the Université de Montréal.

    His subject is the one the whole company depends on. Bio_Sole measures how a person moves, and those measurements have to be sound. They only hold up if they line up with what published research already knows about human movement. That work is his.

    He works closely with Dr. Vladimir Polotski on how prototypes are validated and calibrated, and with the data team on how models are built and checked. Colleagues describe him as the most formally credentialled scientist in the company, and as somebody currently asked to cover a great deal of ground at once.

    He also owns the rules the research runs by. When a volunteer walks for Bio_Sole, the session is non invasive. Names are replaced with codes. Nothing biological is collected. That framework is his, and it is why the company can say its science respects the people it measures. He carries the company's research ties with universities, and his view of credibility is patient: it is earned by contribution, not by introduction.

  • Ali Rizavi

    Ali Rizavi has forty years in power design.

    Read the full biography of Ali Rizavi

    Chicago, Illinois

    Ali Rizavi is the electrical engineer behind the electronics inside the Bio_Sole insole. He is an embedded systems specialist. He has forty years of experience in power supply and power plant design.

    He came to Bio_Sole through Tony Robinson, who leads technology here. The two first worked together about eighteen years ago. Ali was the junior engineer then, and Tony helped him. Years later, Ali came back to help in return. That is the kind of loyalty you cannot hire for. Tony calls him the greatest asset the company has ever had.

    He works from the Chicago area. He also leads electrical engineering teams for an international manufacturer with plants around the world. That is the environment Bio_Sole is moving toward, and it is why his judgment carries weight on hardware.

Commercial and Communications

They take it to market. They also decide how the company speaks, and what it will not say.

    Boston, Massachusetts

    Chuck Deem leads sales for Bio_Sole. He is also the bridge between Atlantic Footcare and the rest of the company, carrying the product from the factory floor out to the market.

    He lives minutes from the Atlantic Footcare plant in Rhode Island, which is the whole point. He is the connective tissue between the people who make the product and the people who will wear it, and manufacturing readiness, retail strategy and distribution all run through him as Bio_Sole moves toward launch.

    He grew up on a farm outside Philadelphia, and his working life began on the manufacturing lines of Johnson & Johnson's McNeil Consumer Products, the home of TYLENOL, during his summers off. He came back after a marketing degree from West Virginia University, and over more than forty years he has led national sales and marketing organizations for some of North America's most trusted consumer health brands.

    He is not precious about the work either. When a major footwear brand was coming to see the plant, he rolled up his sleeves and helped clean it himself. You want to put your best foot forward.

    He has called the Boston area home for thirty-five years, where he and his wife Stacey raised their two children. Away from work he is happiest with family and friends, on the golf course, or on the ski hill.

    You just got to know your target audience, and what they want.
  • Sophie Hargest, Head of Communications Strategy and Media at Bio_Sole

    Sophie Hargest

    Head of Communications Strategy and Media

    Sophie Hargest translates the work of engineers, scientists and inventors for the people it is meant to serve.

    Read the full biography of Sophie Hargest

    Ottawa, Ontario

    Sophie Hargest is Head of Communications Strategy and Media at Bio_Sole, a company working at the frontier of identity and artificial intelligence. Her role is translation: taking the work of engineers, scientists, inventors, and financiers and carrying it, intact and honest, to the people that work is meant to serve.

    She is not a technologist, and that is precisely the point. Technology built for humanity needs someone in the room who thinks first about the humans, and Sophie has spent her career among them: in law, in government, in politics, and in humanitarian response. At Gowling in her early twenties she worked on the NAFTA side accords, the files behind the creation of Nunavut, and the Meech Lake and Charlottetown constitutional rounds. She spent 2 years in provincial affairs at Innovative Medicines Canada, managed a 2025 federal election campaign in a Quebec riding with generations of Bloc Québécois loyalty, and co-founded Ukrainian Settlement Helpers Ottawa, which housed hundreds of displaced families. She ran her own communications firm for 24 years alongside all of it. A background that broad leaves no room for siloed thinking, and she would not have it any other way.

    At Bio_Sole she keeps the company's evidence charter, the rule that no public claim outruns its proof, produces the interview series Ground_Truth™, our micro pods Ground(ed)_Truth and First Person, and leads brand, media, and events, including as Bio_Sole's lead for Identity Week America 2026. She studied sociology at Carleton University, Film and TV Production at Humber College, is a trained mediator, works in English, French and Spanish.

    Her role is translation: taking the work of engineers, scientists, inventors and financiers, and carrying it, intact and honest, to the people that work is meant to serve.

    Philadelphia, Pennsylvania

    Jim Pennewill carries marketing for Bio_Sole. He works on how the company presents itself, which in this business is unusually hard. The product measures your body and proves who you are. Explaining that plainly, without overclaiming, is the whole job.

    He came to Bio_Sole through Bill Tyson, who advises the company on insurance. The two of them go back about twenty-five years. Both grew up around Philadelphia, and both went to Temple University, Bill in insurance, risk and business law, Jim in marketing. Bill introduced him to Todd Gray, and the work has run through the website, the brand and the visual direction since.

    Read the full biography of Daniel Allard

    Dartmouth, Nova Scotia

    Daniel Allard is Director of Creative Content at Bio_Sole. He makes everything the company shows you, and he has been doing this kind of work since 1990.

    His career runs through Canadian broadcasting. He started at Rogers Television in Ottawa, where he did every part of the job, including hosting and, briefly, puppeteering. Then came eight years at CPAC as an editor, cutting the evening news for Prime Time Politics, to a deadline, every night. After CTV Ottawa he spent four years running the studio at The Conference Board of Canada, directing from the control room and setting up live segments with networks here and abroad. Earlier he shot video for the Canadian Real Estate Association for five years.

    Most recently he spent seven years as senior video producer at Vanillasoft, where the work won things. He made the top webinar of 2020. In 2021 his work took five nominations and three wins for video and webinars. In 2022 he was named Production Manager of the Year at the Faces Magazine Ottawa Awards.

    At Bio_Sole he directs and cuts Ground_Truth™, the company's interview series. Sophie Hargest produces it and asks the questions; he brings it to the screen. He also films the real work. The production week footage is his, and so is the line at Atlantic Footcare where the insoles are made. Because he holds that material, this website can show the real thing instead of stock photographs. He carries the continuity too: the booth, the site, the series and the social posts all have to look like one hand made them. That is why Bio_Sole has a house style at all.

    He holds a BA in communication and media studies from Athabasca University. He works from Dartmouth, Nova Scotia. And once, memorably, he got to be Polkaroo.

Coordination and support

Two more people keep the commercial side running, and they are named here because the work is real even when it is not a portrait on a wall. Tess Alikhan is Communications Coordinator. Kristie Marr is Business Analyst.

    Vice Chairman

    Fred Vail has advised Bio_Sole for more than ten years.

    Read the full biography of Fred Vail

    Cotswolds, United Kingdom

    Fred Vail is the Vice Chairman of Bio_Sole. He has been involved for more than ten years, which means he has watched the company through every version of itself.

    He came to it by way of an unusual career. He spent about five years in London building technology startups with Price Waterhouse, including one he took to roughly eighty percent complete before it was acquired. He taught at Harvard for eight years as a senior lecturer. He has worked internationally, including a period in Saudi Arabia, which is where Todd Gray found him. Fred's first question was how on earth Todd had got hold of his phone number.

    He completed a degree at Henley, the business school in Oxfordshire, and he cheerfully admits to having collected more degrees than strictly necessary. He grew up in a military family, went to military school, and lived in a good many countries before settling in the Cotswolds. He still skis the French Alps every winter.

    His role is deliberately strategic rather than operational. He told Todd early on that the last thing he wanted was to run around day to day, and that he would be an advisor instead. He counsels focus, and he is direct about where the company should prove itself first.

    He is also plain about what wins. Everything else, in his view, follows from a demonstration.

    The most important thing that we can do is demonstrate what the company can do and the technology can do.

    William Tyson

    Insurance and InsurTech Advisor

    Bill Tyson has been a chief marketing officer in insurance for about thirty years.

    Read the full biography of William Tyson

    Philadelphia, Pennsylvania

    William Tyson, who goes by Bill, advises Bio_Sole on insurance and InsurTech. He has been involved since 2017, coming up on ten years.

    He has been a chief marketing officer in insurance for around thirty years, including ten years at the insurer level and a stretch working globally. He served two overseas postings, with AIG in Kenya and Cigna International in Hong Kong. Earlier in his career he ran a large professional liability practice for lawyers in New York State. He holds a degree in insurance, risk and business law from Temple University in Philadelphia.

    He is also a founder. In 2018 he built his own firm, fully remote from the first day, now fourteen people, with a software subsidiary that automates insurance work. He is a subject matter expert on insurance for an AI safety venture, and connected to a bar association working group on risk and technology.

    What he gave Bio_Sole early was a way to explain itself to an industry that does not take claims on trust. He sees a fairer future in it, where a person's own measurements could shape their own premium rather than the average of a group they happen to belong to.

    He grew up around Philadelphia and remains loyal to Temple. He is the kind of advisor who tells younger colleagues to reach out any time, and means it. On how to sell any of this, he is blunt.

    A demo is worth 1000 PowerPoint pages.

About the people.

Who founded Bio_Sole?

Todd Gray founded Bio_Sole. He began the work in 2009, and he still leads the company from Ottawa, Ontario.

Who invented the Bio_Sole insole?

Todd Gray designed it. He built the first prototype program in New Brunswick in 2014, and he still designs hardware himself today.

Where are Bio_Sole insoles made?

At Atlantic Footcare in Rhode Island, a manufacturer with forty years of history that is now part of Bio_Sole. Daniel Brown, the company's Chief Financial Officer, led the acquisition.

Has anyone at Bio_Sole worked in foot care before?

Yes. Dr. Bernard Grisoni, who designs the insole, spent sixteen years at Merck as a principal scientist on Dr. Scholl's, where he led the development of sixteen new products.

Who leads engineering at Bio_Sole?

Tony Robinson is Chief Technology Officer. He has thirty years in hardware and has worked in cybersecurity since 1990. The current sensor board has been through seven generations.

Can Bio_Sole explain how its AI reached a result?

Yes. Every model is versioned and every result is logged, so the company can show which version of which model produced a given reading, and on which day. Thomas Elliott, who leads data and AI, owns that infrastructure.

Do qualified researchers check Bio_Sole's science?

Yes. Dr. Vaibhav Shah holds a PhD in biomechanics and is affiliated with the Université de Montréal. Dr. Vladimir Polotski, who holds a PhD in mechanics and control, writes the algorithms. The two of them validate and calibrate prototypes together.

How does Bio_Sole study volunteers?

Sessions are non invasive: a person walks. Names are replaced with codes, and nothing biological is collected. Dr. Vaibhav Shah owns that framework.

Does Bio_Sole have rules about the claims it makes?

Yes. The company works to a written charter, kept by Sophie Hargest, Head of Communications Strategy and Media. Its core rule is simple: no claim goes beyond the evidence for it, and every public page is checked against it.

Who makes the Ground_Truth™ interview series?

Sophie Hargest produces it and asks the questions. Daniel Allard, Director of Creative Content, directs and edits it. He also films the work on the line at Atlantic Footcare, which is why this site can show the real thing rather than stock photography.

We are careful with claims, on purpose.

The Ground_Truth™ platform is designed to produce identity validated observations, not diagnoses. It supplies its measurements to licensed providers, who interpret them. No claim exceeds its evidence basis. Bio_Sole is a companion to professional care, never a replacement for it.

Four of the bios above are still incomplete, and they say so where the gap is. We would rather publish a marked gap than a plausible sentence nobody said.

Ask who's answering.

If you want to know who specifically stands behind a claim on this page, ask. We would rather give you a name than a department.

Ask any of us.

If a bio raises a question, or you think one of these sentences claims more than it should, tell us. A person will answer, and if we got it wrong we will correct it in the open.
