Schwyz-based Liom, an innovator in non-invasive biomarker monitoring and the developer of a non-invasive glucose-monitoring wearable, introduced a €13.9 million (CHF 13 million) extension of its Collection A financing spherical.
The spherical was led by earlier lead buyers, with new participation from Crimson Bull Ventures, Marc Maurer (former co-CEO of On Operating), Melih Odemis (former co-founder and CTO of Yemeksepeti), Alejo Costa Ribalta, associate of enterprise capital agency CRB Well being Tech and former senior govt of Philips and GE Healthcare – bringing its complete Collection A to €40.8 million (CHF 38 million) and its complete funding thus far to €67.6 million (CHF 63 million).
“Now, we will additionally ensure that we’ve not solely confirmed the tactic, however we had the proper crew and the correct amount of luck to generate the required breakthrough improvements in an effort to carry our platform right into a wearable-fitting form-factor,” says Leo Grünstein, founder and CEO of Liom.
In 2025, European HealthTech startups specializing in wearables, biosensing, and preventive care have attracted notable enterprise capital, reflecting investor confidence in applied sciences that ship steady well being insights past conventional scientific settings.
For instance, Sava Technologies Ltd., a London-based MedTech innovator in real-time molecular wearable sensors, raised €16.6 million in Collection A to advance regulatory approval and commercialisation of its next-generation gadget, bringing its complete funding to almost €28 million. In adjoining preventive care domains, Lucis secured €7.2 million in Seed funding to broaden its biomarker-based well being analytics platform throughout Europe, and GlycanAge raised €7.4 million to scale its glycan-based diagnostics for preventive ageing care.
Collectively, these 2025 rounds illustrate a funding local weather the place roughly €31 million is being allotted towards startups creating steady monitoring, personalised metabolic perception instruments, and preventive diagnostics that sit alongside Liom’s non-invasive glucose wearable innovation.
“Our miniaturisation breakthrough considerably will increase gentle throughput versus present state-of-the-art options – even outperforming table-sized lab-scale units by 12x – and with that unlocks prior unseen efficiency, a >24h battery life, smartwatch sizing and manufacturability at scale” Grünstein provides.
Based in 2017 by Leo Grünstein, Liom Well being (previously Spiden) is a Swiss HealthTech startup innovating preventive and personalised well being monitoring by a novel wearable that enlightens customers with real-time biophysical suggestions.
Liom’s first product, anticipated to launch in 2028, is a non-invasive glucose-monitoring wearable that provides a complete view of metabolic well being.
The brand new capital follows Liom’s current breakthrough in miniaturising its proprietary Raman spectroscopy platform, having confirmed its capability to measure glucose non-invasively and because the world’s solely firm calibration-free, i.e. requiring no needles to calibrate in any respect, on over 130 topics in the midst of the previous years.
Liom can also be welcoming Marc Maurer, former co-CEO of On Operating – a Swiss success story valued at greater than €11.8 billion (CHF 11 billion) – as each investor and Board member. Marc brings experience in product, client worth creation, in addition to branding and advertising, particularly on the intersection of well being, health and client merchandise.
His experience will help Liom because it shifts from R&D into product growth and commercialisation.
Maurer states: “Diet and motion are completely key to a top quality of life. Accessing glucose measurements by a wearable in your wrist, with out the necessity for a needle, will permit all of us to know the impression of diet and motion on our physique a lot better and due to this fact dwell a more healthy life. Liom unlocks mass-adoption by shoppers & athletes vs present microneedle CGM units.
“I imagine Liom has the potential to disrupt and considerably broaden the wearable market that has been created by Apple Watch, Samsung Galaxy Watch, Fitbit, Garmin, Whoop, Oura, and so forth – but hasn’t seen sensor-level innovation over the previous decade.”
