Bryson DeChambeau acquires Sportsbox AI and announces an artificial intelligence golf coach
Sportsbox AI just got a new owner, and he’s not exactly a tech entrepreneur 😄
Bryson DeChambeau, two-time US Open champion and one of the most tech-obsessed golfers on the world circuit, just led a group of investors in the full acquisition of the startup he personally used to win the 2024 US Open. The backstory is pretty fascinating: before hoisting the trophy at Pinehurst, DeChambeau used the Sportsbox AI app to identify a slight rightward drift in his shots and corrected the issue just in time. After the win, he mentioned the company during his press conference, became an investor, and has now taken it a step further by leading the purchase of the entire company.
The transaction was confirmed to Bloomberg and involves an eight-figure sum, putting this move well beyond a casual sports bet. Alongside the acquisition, the company also unveiled SAMI, a conversational artificial intelligence coach built on Google Cloud’s Gemini models, which promises to turn biomechanical swing data into personalized guidance for anyone with a smartphone. That might sound like a lot happening all at once, right? But it all makes perfect sense when you understand what Sportsbox AI does, where it’s heading, and why DeChambeau went all in on this technology. 🏌️
What is Sportsbox AI and why does it matter so much
Sportsbox AI is not just another generic sports analytics tool. The company was founded in 2020 as a spin-off from AI Thinktank, an incubator based in Bellevue, Washington, started by Mike and Rich Kennewick — the brothers behind Voicebox Technologies, a pioneering voice recognition company. From the very beginning, the goal was highly specific: use computer vision and artificial intelligence to turn any ordinary video of a golf swing into a complete three-dimensional biomechanical model. That means with nothing more than your phone camera, the platform can capture body movement, identify patterns, measure hundreds of data points, and detect flaws that even a trained human eye would struggle to catch in real time.
The company’s leadership is a big part of this story, too. CEO Jeehae Lee is a former LPGA Tour player who led strategy and business development at Topgolf before co-founding Sportsbox. CTO Samuel Menaker was VP of engineering at Voicebox. Both will remain at the helm after the acquisition, signaling continuity and stability in management. The team of roughly 30 employees is also staying on, and headquarters will remain in Bellevue, though much of the team works remotely.
The technical edge of Sportsbox AI lies in the depth of the swing analysis it delivers. Rather than simply recording and replaying movement, the system generates detailed metrics on hip rotation, torso tilt, center of gravity position, timing of each swing phase, and dozens of other biomechanical reference points. This information is presented in a visual and accessible way, making it useful for experienced coaches and amateurs trying to improve on their own alike. Democratizing an analysis that previously required high-performance labs or academies with expensive equipment is exactly what makes the proposition so powerful.

On the revenue side, Sportsbox operates on a subscription model. There are plans designed for coaches and a consumer option priced at $15.99 per month or $110 per year. The company had previously raised more than $9 million in funding and, according to PitchBook data, was valued at $41 million in a seed round completed in March 2023.
Who left and who came to the negotiating table
The acquisition marks the complete exit of 19 previous investors listed by PitchBook. Among the most recognizable names are Elysian Park Ventures, the PGA of America, professional golfer Michelle Wie West, renowned golf instructor David Leadbetter, Randi Zuckerberg, and Kevin Lin, co-founder of Twitch. It was quite an eclectic group, blending figures from the sports world, digital entertainment, and venture capital.
On the buyer’s side, the official announcement describes the group as investors led by DeChambeau but does not reveal the other participants. What we do know is that the transaction value is in the eight-figure range, as stated by DeChambeau himself to Bloomberg. Considering the company’s last valuation at $41 million, the scenario suggests a significant deal, although full financial details have not been publicly disclosed.
SAMI: when artificial intelligence becomes your personal coach
SAMI is, in practice, the natural evolution of everything Sportsbox AI has already built. The name stands for Sportsbox AI Motion Intelligence, and it functions as personalized coaching powered by agentic artificial intelligence. The core idea is simple, but the execution is pretty sophisticated: you record your swing, the system analyzes the movement in three dimensions, and SAMI transforms that biomechanical data into a conversation. You can ask what’s going wrong, request exercise suggestions, understand why your shot is losing distance or accuracy, and the virtual coach responds based on your actual data — not generic answers copied from a textbook.
Technically, SAMI is built on Google Cloud’s Gemini models, giving the platform access to extremely advanced natural language capabilities. This matters because the difference between a useful AI assistant and a useless one comes down to the quality of contextual interpretation. When SAMI receives your swing analysis data, it’s not just reading numbers — it’s interpreting the context of the movement, cross-referencing performance patterns, considering the user’s history, and delivering guidance that makes sense for that specific person at that specific moment. According to the press release, this marks Sportsbox’s transition from a passive measurement tool to a proactive AI agent.
SAMI is currently in beta, and the company announced it will begin rolling out agentic AI features throughout the second quarter of 2026. The first features, including AI-generated highlights, are already being made available starting this week for subscribers on the 3D Player and 3D Player Plus plans on iOS.
The practical impact of this goes well beyond professional golf. Most people who play golf around the world don’t have regular access to a qualified coach, whether due to cost, availability, or geographic location. Personalized coaching available on a smartphone, capable of analyzing each shot with biomechanical precision and explaining necessary adjustments in natural language, solves a real problem for millions of players. And with Bryson DeChambeau as the company’s new leader, there’s now a massive incentive for this product to be continuously refined based on what works at the highest level of the sport. 🎯
Why DeChambeau is the ideal owner for this company
Bryson DeChambeau is not your average athlete when it comes to technology. Since the start of his career, he’s been known for applying physics, biomechanics, and engineering concepts to golf in a way few players before him had done so systematically. He studied physics in college, used clubs with identical shaft lengths across all his irons to standardize his swing, consulted fluid dynamics experts to understand ball behavior in the air, and transformed himself into a power athlete to gain distance off the tee. In other words, he was already living at the intersection of sports and technology long before any startup entered the picture.
When DeChambeau started using Sportsbox AI for preparation, it wasn’t a marketing endorsement — it was a technical decision based on results. The 2024 US Open episode made that crystal clear: he identified an inconsistency in his movement during the week leading up to the tournament, used the platform’s swing analysis to diagnose the problem with precision, made the adjustment, and won. That kind of use case is exactly what any sports tech company dreams of having as proof of concept. The fact that he went from the victory straight to the microphone and publicly mentioned the company showed the relationship was genuine, and the journey from user to investor to owner unfolded pretty organically from there.
In his official statement, DeChambeau summed up his motivation in a straightforward way: the goal is to make golf more accessible, especially when it comes to quality coaching. The idea is to build something that brings real training to anyone with a smartphone, not just elite players.
At the same time, he made a point of acknowledging the limits of the technology. In an interview with Bloomberg, DeChambeau said that the camera and phone can only tell you so much, and they don’t replace the physical feel that a coach can help develop. That balanced perspective reinforces that Sportsbox isn’t trying to eliminate the work of golf professionals but rather complement it in a smart way.
The Google Cloud partnership and what it represents
One detail that flew somewhat under the radar in the announcement, but carries significant strategic weight, is the partnership with Google Cloud. Beyond serving as the technological foundation for SAMI, the collaboration includes a visibility component that is unprecedented in golf: DeChambeau will carry the Google Cloud logo on his golf bag during the Masters and in future tournaments. According to the press release, this is the first time the Google Cloud brand has appeared on a professional golfer’s bag.
From a technological standpoint, building on Gemini’s infrastructure means having access to continuous language model updates, robust processing power to handle large volumes of video and biomechanical data, and a strategic partnership with one of the most relevant companies in the artificial intelligence ecosystem today. This kind of alliance puts Sportsbox AI in a very different position from a startup building everything from scratch and signals that the company has plans to grow consistently in the years ahead.
What this changes for the sports tech market
The Sportsbox AI move isn’t happening in a vacuum. The market for technology applied to sports is growing rapidly, and golf in particular has been fertile ground for innovation due to the demographic profile of its players and the sport’s historical willingness to adopt performance analysis tools. Club sensors, ball trackers, high-fidelity simulators, and video platforms are already part of many golfers’ everyday routines, and the arrival of conversational artificial intelligence in this context represents the next natural stage of that evolution. What SAMI proposes is essentially turning all of that data collection into dialogue, which dramatically lowers the barrier to entry for anyone who wants to use technology to improve their game.
Another important point is the business model this approach enables. When you have a product that delivers personalized coaching via artificial intelligence in a continuous and scalable way, the revenue logic changes completely compared to the traditional model of lessons with a pro. The platform can grow horizontally without the human bottleneck, making it far more attractive from a scalability standpoint. For investors and the market as a whole, that’s a pretty compelling proposition — especially with an internationally recognized name leading the company and a proven success story on the course. Literally.
DeChambeau told Bloomberg he has been using the technology during his preparation for the Masters this week and plans to continue using it during and after the tournament. The fact that the acquisition announcement was timed for Masters week — one of the most prestigious events in world golf — is no coincidence. The peak visibility the tournament provides should significantly amplify the reach of the news and put Sportsbox AI on the radar of millions of viewers around the world. ⛳
The combination of an elite athlete who deeply understands technology, a platform with real biomechanical analysis capability, and cutting-edge AI infrastructure provided by Google Cloud creates a scenario where Sportsbox AI has everything it needs to become a benchmark not just in golf but potentially in other sports where movement and biomechanics are central to performance. 🚀
