London-based Simple Life raises over €33 million in a Series B round backed by Kevin Hart to scale its AI health coach
London-based AI health coaching app Simple Life has raised 33 million in a Series B round led by Hartbeat Ventures, founded by actor and entrepreneur Kevin Hart, with participation from Liquidity, an AI-driven private credit firm.
The new funding comes after a year of rapid growth for the startup. In 2024, Simple generated $100 million in revenue, marking a 64% year-over-year increase, and reached operating profitability. The app has now been downloaded more than 20 million times, with users collectively losing over 17.5 million pounds.
“I’m hyped to back Simple through my fund HartBeat Ventures. Simple is truly changing the game in health, and HBV wants to be front row for that,” said Kevin Hart.
Simple uses its AI-powered health coach, “Avo,” to deliver personalised plans, real-time nutritional analyses, and on-demand coaching. Recognised as MedTech Breakthrough’s 2025 “Best Virtual Health Coach,” Avo sent 19 million coaching messages in January alone. A peer-reviewed study of 50,000 users found that 42% achieved at least 5% weight loss at one year.
“Most weight-loss solutions fixate on the end goal. We focus on the journey, making it adaptive, rewarding, and sustainable. With our data and approach, there’s no need for obsessive calorie counting or extreme restrictions,” said Mike Prytkov, founder and CEO of Simple.
The company plans to use the Series B funding to expand its AI capabilities in hyper-personalisation, multimodal coaching, gamification, and AI-assisted content creation. A gamified companion app, currently in testing, has already shown positive results for retention and weight-loss outcomes.
Paul Brodie, Managing Director at Liquidity, added: “This financing reinforces our commitment to empowering growth-stage industry innovators with fast, flexible capital tailored to scale with their ambitions.”
Yuri Gurski, founder of Flo Health and Palta, an early investor in Simple, noted: “Simple brings the formula of scientific credibility paired with user experience to weight loss, with speed, scale, and results the market has never seen before.”
Founded in London, Simple Life now serves more than 800,000 active subscribers. Its approach combines evidence-based health strategies with scalable AI coaching, positioning it as one of the leading players in digital wellness.
