An AI toilet camera just raised $10M to track gut health

Wearables track your sleep stages, resting heart rate, and training strain with obsessive detail. Yet the moment you walk into the bathroom, the entire consumer health ecosystem goes blind.

Austin-based startup Throne Science is trying to fix that blind spot. Just four months after shipping its AI-powered toilet camera to consumers, the company has raised a $10 million Series A led by Will Ventures, with backing from Emerson Collective and a slate of other venture funds. The round pushes Throne's total funding to nearly $18 million since its 2023 founding.

Co-founder and Chief Product Officer John Capodilupo came from Whoop, where he served as co-founder and CTO. His interest here is personal: he was diagnosed with ulcerative colitis and spent years managing a chronic condition without continuous data tools. His core belief is that single checkups miss the big picture, and only dense longitudinal data can turn guesswork into actionable patterns.

Twelve models watching the bowl

The Throne One hardware costs $400, paired with an ongoing subscription of $5.99 per month or $69.99 per year to cover cloud inference. It clips directly onto the rim of standard toilets without tools or plumbing.

A downward-facing optical sensor captures images inside the bowl, which pass through a pipeline of around 12 computer vision models. Gastroenterologists helped train the system to evaluate stool using the Bristol Stool Form Scale, classifying output into seven standard clinical types alongside measurements of color, consistency, buoyancy, and frequency.

It does not stop at visual data. An integrated audio sensor monitors urinary flow rate, volume, and duration to calculate hydration levels, working even when users stand. To avoid mixing up household members without forcing everyone to scan a fingerprint before flushing, the device relies on passive Bluetooth proximity detection from paired smartphones. Data travels via TLS 1.2 encryption and rests under AES-256 encryption, with images anonymized before human review.

Earlier in July 2026, Throne rolled out a beta of its Gut Health AI coach. Powered by large language models, the coach asks conversational follow-up questions after unusual bowel events, connecting flare-ups with recent stress, sleep deprivation, or diet changes.

The emerging battle for the porcelain throne

The bathroom is rapidly turning into contested hardware territory. Legacy fixture maker Kohler launched its Dekoda sensor in October 2025 at $599 with an annual subscription up to $156, opting for active fingerprint scans. Meanwhile, Casana launched its $199 Smart Seat just days ago, tracking blood pressure and heart rate directly through the toilet seat without any cameras or microphones.

Throne CEO Scott Hickle framed their matchup against Kohler as David versus Goliath, betting that specialized computer vision and battery life will outweigh Kohler's massive distribution advantage.

On the clinical side, Throne recently submitted an academic abstract claiming its visual AI matches board-certified gastroenterologists at stool classification. Validation studies are currently underway with researchers at Harvard, Stanford, and the University of Chicago.

Still, readers should keep expectations grounded. The Throne One is legally categorized under the FDA General Wellness framework finalized on January 6, 2026. That means it cannot claim to diagnose or treat medical conditions. While leadership openly talks about becoming a smoke detector for colorectal cancer, that future requires formal 510(k) or PMA clearance as a medical device, which the current gadget simply does not have.

Why it matters

GI health has historically been one of the hardest categories to monitor because intermittent clinical visits offer zero insight into daily digestive fluctuations. Throne's approach is undeniably clever: transplanting the continuous biometric tracking model pioneered by Whoop and Oura into a neglected bodily function.

For people managing chronic conditions like irritable bowel syndrome or Crohn's disease, the device could offer genuine relief from tedious manual journaling if they can stomach the cost. But at $400 upfront plus recurring software fees, it is a hard sell for the casual wellness enthusiast.

The real elephant in the room remains the privacy hurdle. Even with robust cloud encryption and anonymization protocols, mounting a camera inside a family toilet is a heavy psychological lift. Hardware like Casana's sensor seat shows that consumers might prefer camera-free alternatives whenever possible.

In our view, Throne's long-term survival will not hinge on being a neat lifestyle gadget. If the company wants to prove its valuation, it will have to bridge the gap between wellness tracking and genuine clinical diagnosis, proving to both doctors and insurers that stool photos belong in standard medical charts.
