Keto-Mojo unveiled a photoacoustic breathalyzer that measures acetone in the breath to assess ketosis without fingerpricks or disposable test strips, and opened preorders for a limited Founders' First Reserve. The [FinancialContent Business Page](https://www.financialcontent.com/article/gnwcq-2026-11-14-keto-mojo-unveils-worlds-first-photoacoustic-breathalyzer-advancing-non-invasive-ketone-monitoring) said the device was introduced at Hack Your Health 2026.

## How the UV-C Photoacoustic Breathalyzer Works

The [Keto-Mojo](https://akta.pro/company-profiles/0006l61/keto-mojo) device uses UV-C photoacoustic spectroscopy, a technique built on principles first discovered by Alexander Graham Bell in 1880. Ultraviolet light targets acetone molecules in a breath sample; when those molecules absorb light, they generate tiny measurable pressure waves that determine acetone concentration. The company said the approach is designed to overcome sensor degradation and interference from other gases that have limited existing breath ketone monitors.

Keto-Mojo presented the device at Hack Your Health 2026, an event it said has brought together researchers, practitioners and innovators since 2017, alongside founder Robin Switzer's work in metabolic health education. The announcement coincided with Greenow's main-stage presentation, "Ketones on Demand: The Missing Control Lever in Human Optimization."

"We've always believed that you can only improve what you measure," said Dorian Greenow, Founder and CEO of Keto-Mojo. "For too long, people have had to choose between the accuracy of invasive blood testing vs. the convenience of unreliable breath or urine testing. We developed UV-C photoacoustic technology so that people don't have to compromise."

Greenow described the device as part of a shift from standalone readings toward connected measurement. "Measurement gives us data. Context gives it meaning. And understanding our individual patterns gives us the opportunity to make productive changes," he said. Keto-Mojo said the breathalyzer will expand its monitoring portfolio beyond the FDA-cleared GK+ Blood Glucose & Ketone Meter it has sold since 2017, with measurements connected through its MyMojoHealth digital platform.

## Keto-Mojo's Earlier Product Releases

According to akta.pro [company records](https://akta.pro/company-data), Keto-Mojo launched the GK+ dual glucose and ketone blood meter in 2020 with Bluetooth connectivity, patented Super Sip strip technology and a lifetime warranty. The same records show the company launched the MyMojoHealth mobile app and desktop dashboard in 2023 for logging readings, calculating GKI, trend analytics and provider data sharing, and in 2024 extended MyMojoHealth with CGM data ingestion through Apple Health integration and EHR system integration for clinical workflows and remote patient monitoring. The records list Netguru as the software development firm that built connected health IoT technology for Keto-Mojo.

## Founders' First Reserve Timeline

Preorders for the Founders' First Reserve are open, and Keto-Mojo said limited production is expected to begin in January 2027. Devices will be delivered on a first-come, first-served basis as units become available. A broader commercial launch is planned for 2027, when the company said it will share additional details about the product and its expanding metabolic health ecosystem.
