Health and wellness technology startup Keyto (San Francisco, CA) has announced that it has raised $2.5 million in its effort to bring what it says is the world's smartest breath analyzer and personalized ketogenic diet program to market.

The company’s health program consists of a $100 smart breath sensor that can detect when the body is in ketosis – a state in which it burns fats rather than sugars and carbohydrates for fuel – and a scientific smartphone app that provides personalized food and lifestyle recommendations based on an individual’s physiology. The ketogenic diet – often called a “low-carb” diet – and its possible health benefits has seen increasing interest among health-conscious consumers, but traditional methods for detecting when one is in a state of ketosis have been inconvenient or expensive.

Such methods include detecting ketones using urine strips, which are messy and inaccurate, or with blood tests, which can be painful and expensive. Keyto takes a different approach by detecting a byproduct of ketone production – acetone – in the breath.

“Over the past year, the ketogenic diet has become one of the most popular diets in the United States,” says David Sacks, co-founder and general partner of Craft Ventures, which led the funding round. “We believe the market is ripe for a device like Keyto, which can help people reach their goals more effectively. The Keyto team’s proven track record combined with the unique form factor of its product make it a very compelling investment.”

To use the Keyto breath sensor, users simply breathe into the cylindrical device and view the result on the Keyto app, which is presented as an easy-to-understand “Keyto Level” – the higher the level, the greater the state of ketosis and the more efficient the fat burn. The iOS and Android app, says the company, uses machine learning algorithms to deliver the right information at the right time to individuals based on their Keyto Level, body measurements, age, and goals.

The app includes personalized meal plans and lifestyle recommendations, a comprehensive library of ketogenic recipes, as well as educational and inspirational videos. In addition, the app features a built-in social community with other users, while also providing a color-coded guide of over 10,000 items (the Keyto Code) showing which foods to eat while on the ketogenic diet.

In addition to Craft Ventures, other investors participating in the funding round include Floodgate Fund, Abstract Ventures, and Hydra Ventures as well as leading entrepreneurs Julia Hartz (Eventbrite co-founder and CEO) and Kevin Hartz (Eventbrite co-founder and early investor in Pinterest, PayPal, and Airbnb).

“The caliber of our investment partners is a testament to the strong product we have built over the past year,” says Dr. Ethan Weiss, associate professor and preventative cardiologist at UCSF and co-founder of Keyto, Inc. “We can now bring one of the most promising and sophisticated health programs to market. We have made the science behind the ketogenic diet simple with a device that can track metabolism in real-time paired with an app that provides actionable recommendations to help people lose weight fast while maintaining healthy lifestyles.”

The funding, says the company, will allow it to expand research and development of its proprietary gas nanosensor as well as manufacturing capabilities, and coincides with the launch of the company’s presale campaign on Indiegogo. Keyto will ship in early Q1 2019.
