London Startup Targets 200 Million Patients After $100M Raise

Jan de Vries · 2026-09-18

London-based Penelope Health just closed a $100 million funding commitment, and it's not just another healthcare AI story. The company is building something that could quietly reshape how insurance rules get applied in real time. ### What Penelope Health Actually Does If you've ever tried to figure out whether a procedure is covered by insurance, you know the pain. The rules are scattered, constantly changing, and written in a language that seems designed to confuse. Penelope Health takes that mess and turns it into a single, searchable layer that healthcare companies can plug into. Dr. Sohum Patel, CEO and co-founder, put it bluntly: "The rules that determine whether care is covered by insurance are foundational to the healthcare system, yet they remain opaque, fragmented, difficult to interpret, and are constantly changing." His team wants to turn that complexity into a dependable, up-to-date reference. Right now, Penelope's platform covers policies for over 200 million Americans, spanning more than 15,000 procedures and drug codes. That's a massive chunk of the insured population. ### The Money and the Partnership The $100 million commitment comes from Thoreau, a HealthTech infrastructure platform, along with existing backers Bertelsmann Healthcare Investments, Twine Ventures, and Seedcamp. But this isn't just a cash injection—it's a partnership. Penelope and Thoreau are teaming up to create a shared layer for real-time payments and clinical rules. Mattijs De Paepe, CTO and co-founder, explained the vision: "Realising our vision requires a deep technical understanding of constantly evolving payer rules. We are excited to build the infrastructure for AI to power a more efficient healthcare system." He added that the opportunity goes far beyond any single workflow. ### Why This Matters for European Startups Penelope's raise is part of a broader wave of investment in European healthcare infrastructure and AI tools aimed at cutting administrative workloads. This year alone, EU-Startups has tracked around $200 million across comparable rounds. - Stockholm-based Tandem Health raised $95 million. - Berlin-based Recare secured up to $40 million. - Barcelona-based Health Force brought in $4.6 million for AI agents that handle prior-authorisation checks and claims. - In the UK, London-based Semble raised $38 million to scale its healthcare management platform, while Flexzo AI secured $11.3 million for agentic healthcare workforce technology. These numbers suggest investors are betting big on tools that reduce the friction between payers and providers. ### The Founders Behind the Vision Penelope was co-founded in 2025 by Dr. Patel and De Paepe. Before starting the company, Dr. Patel worked in the UK's National Health Service at Royal Free London and University College London hospital systems. He saw firsthand how administrative complexity interferes with patient care. De Paepe spent nearly four years at Via Transportation, building machine-learning systems for transit products. Their combined experience—clinical and technical—gives them a unique angle on a problem that's plagued healthcare for decades. ### What's Next? The funds will be used to create new products that bring administrative efficiency to navigating payer requirements. Penelope's platform replaces custom, one-off connections and manual searches with a single connection any system can use. As De Paepe noted, "We believe that a shared infrastructure layer can remove administrative burden for both payers and providers." If they pull it off, it could be a game-changer for how healthcare gets paid for in America. For now, keep an eye on this London startup. With 200 million patients already covered and $100 million in fresh backing, they're just getting started.
