Physical AI personal trainer — a human-like, live-in coach for the whole family at 1/10th the cost.
Confirmed by founderWe help families put a world-class personal trainer in their home, a life-size, human-like AI coach named Emma, so elite health becomes a daily habit for the whole household instead of a luxury for one. A human trainer runs $175 an hour and serves one person. For $200 a month, Emma coaches the entire family, 24/7, across every discipline, and she improves at the speed of software. Fitness is the wedge. The prize is the AI companion that runs the family's health: training, recovery, sleep and nutrition. Today's AI has a mind and no body. We give it a body, a superhuman mind and bring it home.

Today's AI is trapped behind screens and text boxes. Reduced to a voice in your ear. Locked in a cage. For that intelligence to matter in fitness and wellness, it must take physical form. Meanwhile, the most powerful engagement medium ever invented, the human being, does not scale: a personal trainer costs $175 an hour, for one person, which is why most people who want one never get one. Two curves are converging: AI that can finally see, reason and converse like a human, and record willingness to pay for real coaching. What's missing is the body.
We give it one. Emma is a life-size, human-like coach who is physically present in your home: she sees you, hears you, talks with you, and reacts to every rep, every strike, every subtle shift in form, in real time. She knows each member of the family, and she gets better at the speed of software. For 60 years, at-home fitness has meant distributing the same pre-recorded class to five people or five million. GROWL replaces distributing content with distributing companionship: dynamic, 1-on-1 coaching for the whole family. Fitness is our wedge to bring Physical AI into the home. It is the one category that demands physical presence, creates daily engagement, and commands premium retention. Whoever owns that daily ritual owns the launchpad for everything else in wellness.
GROWL generated $570K in pre-orders within 30 days on Kickstarter, landing in the top 2% of campaigns ever, with 70% live-campaign conversion at 3x ROAS and no refund guarantees — achieved with only a prototype and a small team. The average pledge was $2,514, and 92% of backers were families averaging $200K+ in household income: exactly the target market. The company has raised $4.75M in Seed funding to date, led by Skip Capital. Product R&D is complete, industrialization is underway with Compal, a Tier-1 manufacturer, and the core system is protected by granted utility patents in the US and Europe. Emma, GROWL's generative AI coach, is running on-device today. GROWL is now raising an $8M Seed+, with $5.5M committed and ~$2.5M remaining to close.

We're raising an $8M Seed+ round with $5.5M committed to date, anchored by a large family office representing leading families across Korea, the US and the Middle East, with unique celebrity relationships, investing together with a partner from their network, alongside Skip Capital, our lead at Seed. Terms are set. Only ~$2.5M remains to close.
We didn’t just run a campaign; we passed a massive stress test.
The Result: We raised $560,786 in 31 days from 235 backers.
The Rank: This places GROWL in the top 2% of Kickstarter campaigns ever.
The Commitment: The average pledge was $2,514, proving high-ticket willingness to pay.
We sold half a million dollars of a product that did not exist, had zero brand awareness, and carried a 9 month delivery wait with no product or refund guarantees. We proved not only interest, but deep market resonance.
A few quotes from our backers:
Lauren: “We are so excited for Growl! The whole family is looking forward to the different features available! My husband is looking forward to the boxing, I am looking forward to the strength and yoga, and our kids are looking forward to the games. This will allow us to have fitness as a top priority for the entire family!”
Scott: “I waited for Fit-XR to become real and to push it. I wanted to sweat, box, and learn for real, and without a headset on. I wanted Growl.”
ATHLETECH: ”Connected fitness startup GROWL has emerged from stealth mode, raising $4.75 million in seed funding for an exciting new product: a wall-mounted, AI-powered punching bag that projects a life-sized virtual coach into people’s living rooms.”
TECHCRUNCH: ”GROWL is building the Peloton of boxing.”
THE VERGE: ”Unlike similar interactive trainers such as the Lululemon Mirror or Tonal, GROWL encourages physical interactivity with its screen that doubles as a punching bag you can actually hit.”
GAMESBEAT: ”The Austin, Texas and Paris-based connected fitness startup emerged from stealth to tout its fitness coach product for the whole family. It focuses on being a personal, at-home boxing and fitness coach, [] offering an immersive, gamified and AI-enabled experience designed for the whole family.”
FAST COMPANY: ”This AI-powered punching bag looks like the future of fitness. Growl uses sensors, cameras and AI to turn a boxing heavy bag into an augmented reality trainer.”
Austin: “I've been in the fitness industry for 20+ years and I've seen and used nearly every type of commercial and home equipment. Growl is the most innovative and game-changing device I've seen in years, and I can't wait to personally use this for my family and also recommend it to others!”
