Exein is addressing this need at a very fundamental level, focusing on securing devices throughout their entire lifecycle. 

Product Description: Nyxoah is a medical technology company that has developed the Genio® system, a minimally invasive, lead-free neurostimulator for treating Obstructive Sleep Apnea (OSA). The system offers an alternative for patients who cannot tolerate CPAP therapy, using hypoglossal nerve stimulation to keep the airway open during sleep.

 

2025 Highlights: 2025 was a pivotal year for Nyxoah, with the company securing up to U.S. $77 million in financing in November to drive the U.S. commercialization of its Genio® system. A major milestone was the FDA approval for the Genio® system in August, followed by the first U.S. commercial patients being implanted in October. The company reported a 56% increase in revenue in Q3 2025 compared to Q3 2024. 

 

Why? 

We’re drawn to solutions that solve real human problems in straightforward ways. Sleep apnea is a widespread issue, and Genio® offers a genuinely different approach for patients who’ve exhausted other options. What we’re most curious about is how quickly this becomes part of everyday medical practice. That adoption story is what makes Nyxoah worth watching.

 

Product Description: Neko Health is a health-tech company focused on preventive healthcare. Their core product, the Neko Body Scan, is a non-invasive health check that uses over 70 sensors and AI to detect early signs of diseases like cardiovascular risks and skin cancer.

 

2025 Highlights: Neko Health’s 2025 was marked by a $260 million Series B funding round in January, valuing the company at $1.8 billion. This funding is fueling expansion into the US and broader European markets. The company has a waitlist of over 100,000 people and is accelerating its UK expansion with new locations planned in London and Birmingham.

 

Why? 

Neko Health feels genuinely exciting because it flips the way most of us interact with healthcare. Instead of waiting for something to go wrong, it encourages people to check in on their health early, in a way that feels accessible and modern. The fact that so many people are willing to wait for this experience says a lot. We’re really curious to see how easily this kind of preventive care becomes part of everyday life, beyond the early adopters who are already sold on the idea.

Product Description: Sateliot is the first LEO satellite operator to provide global NB-IoT connectivity using 5G standards. Their constellation of nanosatellites acts as cell towers in space, extending mobile network coverage to 100% of the Earth’s surface for standard cellular IoT devices.

In October, Sateliot achieved a world-first by connecting a standard 5G IoT device directly to a LEO satellite. The company has signed recurring contracts worth €250 million with over 450 customers in more than 50 countries.

 

Why? 

Coverage has always been IoT’s biggest constraint. Sateliot removes it. Once you can connect anything, anywhere on Earth, the real question becomes: what do we do with it? Agriculture, logistics, energy, infrastructure… the possibilities multiply. What impressed us most wasn’t the funding or the technical achievement. It was the €250M in recurring contracts already signed. That’s real demand, not speculation. We’re watching to see which use cases take off first.

Founder and CEO Raffaello D’Andrea, who was inducted into the National Inventors Hall of Fame in 2022 for his co-creation of the Kiva system, continues to lead the company’s innovation efforts.

 

Why did we choose them?

Most companies get locked into their lane. Verity could have just dominated warehouse automation, but instead they’re exploring sustainable agriculture. That willingness to ask “what else can this technology do?” feels like genuine curiosity, not just chasing trends. It suggests a team that’s thinking bigger than their current market.

Conclusion

 

 

The European IoT landscape this past year was
more vibrant and dynamic than ever.
But what struck us most wasn’t just the funding or the headlines, it was the diversity of problems these companies are solving.What these 10 companies have in common isn’t their size or their funding (though that matters). It’s their obsession with getting something right, whether that’s inventory accuracy, patient outcomes, secure device authentication, or sustainable agriculture. They’re the kind of companies that will define what IoT actually becomes, not just what it hypes itself to be.

 
The IoT revolution isn’t coming. For these companies, it’s already here.

 
 
 
And as we head into 2026, we’re genuinely excited to see where they take it next. Keep an eye on them… they’re just getting started.
