Finn Stevenson & Flok’s Disruptive Digital Physiotherapy
Listen to this deep-dive interview with Finn Stevenson, who brings a unique combination of medical expertise, startup experience, and relentless ambition to solve one of healthcare’s biggest headaches: scalable, accessible physiotherapy.
Key Takeaways:
Direct Problem, Clever Solution
Drawing on his experiences as an Olympic-level rower and healthtech professional, Finn noticed a gap:
“For most people, access to high-quality, frequent physio is nearly impossible.” Enter Flok: an AI-powered physiotherapist offering on-demand, regulation-compliant digital care.
AI Meets NHS Service Models
Rather than building another SaaS product, Flok became a licensed healthcare provider.
“We are a CQC-approved provider, treating NHS patients directly using our technology and clinicians.” This makes procurement smoother and delivers real outcomes for both patients and the NHS.
Technology Built for Safety & Scalability
Flok’s approach shuns off-the-shelf LLMs in favour of a domain-specific language for clinical reasoning, ensuring safe, explainable decision-making at every step. The system combines real-time video assembly (with a real physiotherapist, Kirsty, as the face of the AI) and robust guardrails against clinical risk.
Adoption and Impact
The results speak for themselves: 68% of patients offered Flok’s service choose it over traditional care, covering ages 18 to 75, and less than 2% need traditional escalation. “Positive patient feedback is central. If people aren’t happy, we don’t have a business.”
“If you offer people same day access to care, no waiting list, 24/7 appointments, no travel… a very large number of people find that is very compelling.”
Startup Journey & Scale
Investment Ready: Raised £3.2M pre-product, pre-team. Investors love the addressable market: 80% of healthcare spend is on the delivery of services, not just tools.
Built in Cambridge: Access to deep tech talent, regulatory expertise, and Europe’s largest bio campus makes Cambridge a “no-brainer” HQ.
Actively Hiring: From engineering to clinical and commercial roles—Flok is scaling rapidly, innovating across new therapy areas.
