Show Notes 182: Cambridge's Next Generation of Deep Tech Innovators: Meet the 2026 #21toWatch

Cambridge's Next Generation of Deep Tech Innovators: Meet the 2026 #21toWatch

Episode 182 features five of this year's #21toWatch winners—and if you're in the startup ecosystem, this one's unmissable.

For those unfamiliar, #21toWatch is the region's flagship innovation showcase, and the numbers speak for themselves. Over eight cohorts, 168 companies have landed on the list and collectively raised a staggering £721 million. This year marks a particularly poignant milestone: it's Faye Holland's final year running the programme after eight years at the helm. But she's gone out with a bang.

What Makes Cambridge the Region's Innovation Capital?

Here's the thing that keeps coming up in every conversation: Cambridge's ecosystem is genuinely different. As Sam from Myonerv puts it:

"You've got a city dedicated to research and you've got the university here and you've got industry closely tied with it. In such a small space, the concentration of talent and great minds really must be number one in the world."

It's not just the brilliant people cycling past you on the street—though there's plenty of that. It's the culture of collaboration and support that makes the difference."

Five Companies Worth Your Attention

• Cyclana Bio is tackling drug discovery from first principles, focusing on the extracellular matrix (the "biological dark matter" comprising 90% of your tissue). Their multidisciplinary approach spanning Cambridge and Manchester is already attracting serious attention, with £50 million raised.

• Obasense is developing ultra-sensitive gas sensors for indoor air quality monitoring—particularly timely given the UK's new mould regulations. The founder, Osarenkhoe Ogbeide, is also building African mythology comics on the side. Yes, really.

• Myonerv is creating wearable neurostimulators for stroke rehabilitation. Sam's personal story—inspired by his cousin's stroke—drives a compelling business model targeting the US market's $60 billion opportunity.

• NANOPLUME just announced £2.2 million in funding for their bio-based aerogel thermal insulation. Three times more insulating than conventional materials, 60% lighter, and fully circular. They're eyeing product launch within 18 months.

• Polytecks is mapping bioelectricity through flexible electrode arrays—starting with veterinary cardiology (dog heart disease affects over 80% of dogs) before moving to human diagnostics.

Key Takeaways for Founders

The judges highlighted something crucial: these winners aren't solving single problems. They're building enabling technologies that transform across multiple sectors simultaneously. That's resilience. That's intelligence.

And here's the uncomfortable truth about getting head-down with your technology: it's not enough. As Reuben from Polytex emphasises:

"A company is way more than just the technology. That's something one has to understand from the very beginning."

Competitions like 21 to Watch force you to articulate your vision, crystallise your pitch, and—crucially—build the networks that actually move the needle.

What They Need (And How You Can Help)

This is where it gets interesting. The winners have put out specific calls:

• Sam is actively building US partnerships (Boston, San Diego, Chicago, Houston)

• Reuben needs veterinary distribution expertise and investors

• Tara is hunting cold chain pilot opportunities

• Lea is literally asking for menstrual fluid donations for research assays

If any of these resonate with your network or expertise, the podcast provides direct pathways to connect.

The Bottom Line

This episode captures something essential about where UK deep tech innovation is heading. These aren't incremental improvements—they're fundamental reimaginings of how we solve problems in healthcare, climate tech, and industrial systems.
