Calibre is available from £69 a month. Calibre has raised $3.3M in pre-seed funding to date, 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.

Despite rising life expectancy, people in the UK now spend around 25 per cent of their lives in poor health. 74 per cent of UK adults believe that establishing good health habits is key to preventing future illness, yet 37 per cent still find it difficult to know what their body actually needs, and are left guessing. Calibre’s approach identifies the underlying drivers of people’s health by connecting medical history, daily behaviours and environmental context with the right diagnostic tests. By combining a clinician-led approach with causal AI, Calibre provides members with a complete, evolving picture of their health and a personalised plan to improve their daily energy and take action on long-term health risks.

It removes the need for guesswork, delivering a level of insight previously limited to elite athletes and the wealthy. All clinical care is currently delivered by Calibre’s partner DocTap, a CQC-registered provider. Calibre has submitted its own CQC application, reflecting its commitment to delivering care to the highest clinical standards.

Calibre was founded by Alexander Weber, Founder and CEO, who spent the past decade building and scaling high-impact consumer companies. He joined N26 as one of its earliest team members, later becoming Chief Growth Officer as the business scaled beyond €200 million in revenue. Ben Levy, Founder and Chief Technology Officer, brings over 20 years of software engineering experience.

He previously built and scaled Healthtech companies such as Elvie and Manual beyond €100 million in revenue, and Dr Reinhold Innerhofer, Founder and Chief Medical Officer, who is a medical doctor and sports scientist who has worked with Olympic medallists, world champions and hundreds of ordinary people to improve their health. According to Alex Weber, Co-founder and CEO of Calibre, the last few years have seen 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.” Manuel Grossmann, General Partner at Amino Collective, commented. “Consumer health has been full of tools that track everything and change nothing.

Calibre is changing health outcomes by understanding what's actually driving them, and helping you to take action." Timo Boldt, Founder and CEO at Gousto, commented: “I built Gousto on the belief that food is medicine. But food is only a part of the picture, and the UK's health crisis makes that clear as people are spending decades of their lives in poor health.

What's missing is the full picture and the personalised insight to act on it. That’s where Calibre comes in.” Calibre has opened its waitlist ahead of its initial rollout:
