Calibre, a London-based HealthTech company, exits stealth mode after raising €2.8 million (£2.5 million) in pre-Seed funding to date. The company has also introduced a new category in proactive health called Causal Health Navigation.
The funding was led by Berlin-based Amino Collective, alongside Daybreak Ventures, Cocoa Ventures and a group of experienced founders, operators and medical experts. Prominent angels include Gousto founder Timo Boldt, and N26 co-founder Maximilian Tayenthal.
Alex Weber, co-founder and CEO of Calibre, said, “Over the last years, we have been witnessing a generational shift in how people think about health – from health being the absence of sickness to it being the foundation to live life fully. Left alone by the system, people are now in the era of health guesswork. Calibre is what comes next: a proactive health partner for life that deeply understands your full picture, tells you what’s actually driving your health, and guides you as your health evolves. Our vision is a world where everyone has the health to realise their potential.”
Calibre was founded in 2025 by Alexander Weber (CEO), former Chief Growth Officer at N26; Ben Levy (CTO), former CTO at the HealthTech companies Elvie and Manual; and Dr Reinhold Innerhofer (Chief Medical Officer), a physician and sports scientist.
The company’s proactive health membership combines diagnostics, clinical expertise, and causal AI to help people understand their health and exactly how to change it.
According to the company, despite rising life expectancy, people in the UK now spend around 25% of their lives in poor health. “74% of UK adults believe that establishing good health habits is key to preventing future illness, yet 37% still find it difficult to know what their body actually needs, and are left guessing. Many are turning to AI chatbots for answers, with 230 million people now asking health-related questions on ChatGPT each week,” Calibre mentioned in the press release.
The UK startup opines that general AI tools alone are insufficient to deliver health outcomes. Its approach involves identifying the underlying drivers of people’s health by connecting medical history, daily behaviours and environmental context with the right diagnostic tests.
The company states that it combines a clinician-led approach with causal AI to give members an evolving health picture and a personalised plan to boost daily energy and address long-term health risks. It claims to remove the need for guesswork, delivering a level of insight previously limited to elite athletes and the wealthy. Calibre is available from €79.3 (£69) a month.
It has applied to become a CQC-regulated provider in the UK, where all clinical care is currently delivered by its partner DocTap, a CQC-registered provider. The UK is Calibre’s initial launch market, with plans to expand internationally.
