We're here because you deserve more than a quick prescription

At Genwell, we believe weight and metabolic health care should be comprehensive, compassionate, and built around you – not just medication.

That’s why we've built a new standard of doctor-led support: personalised, high-touch, and deeply human.

Our story

Genwell began with a simple realisation: too many people seeking support with weight and metabolic health were being offered medication, but not the wider care needed to make change last.

Jason Keane and Dr Kartik “Tiko” Modha – long-time collaborators who have built and scaled health-tech ventures together before – saw this gap firsthand. Many people weren’t just looking for a prescription. They wanted to be listened to, understood, and supported. They wanted guidance, clinical continuity, and a team that could address the full picture: habits, hormones, wellbeing, and long-term health.

So we created Genwell to raise the standard.

From day one, our mission has been to build an outstanding multidisciplinary team – bringing together dedicated doctors, wellbeing coaches, and specialist expertise to deliver safer, more complete, and more human support.

Working at Genwell

Our culture is grounded in clinical excellence, empathy, and teamwork. We take the time to listen, to do things properly, and to support one another as we support our clients.

We welcome doctors from one of the UK’s largest GP-only online communities (TGG) and from across the profession, who want to practise in a modern, supportive environment, alongside wellbeing coaches and specialist colleagues, with a shared focus on outstanding patient care and long-term outcomes.

If you believe in personalised multidisciplinary care – and want to shape the future of weight and metabolic health in the UK – you’ll feel at home at Genwell.

Jason Keane

Jason Keane

Co-founder and Chief Executive Officer

My work is shaped by 25+ years building patient-centric health businesses in the UK. I’ve scaled platforms from early traction to national impact, including leading the growth of Patient Access for over ten million UK patients. At Genwell, we’re building a doctor-led metabolic health service combining clinician signposting and multidisciplinary care for lasting patient outcomes.

Dr Kartik Modha

Dr Kartik Modha

Co-Founder and Chief Medical Officer

My work is shaped by over two decades of clinical experience and by seeing the limits of fragmented care. I don’t believe metabolic health is about willpower alone. Hormones, sleep, stress, insulin resistance, and daily pressures all matter. My focus is personalised, evidence-based care that addresses root causes and supports long-term health.

Dr Caroline Butler

Dr Caroline Butler

GP and Chief Clinical Officer

I work with people facing complex health challenges. Hormones, insulin resistance, stress, and long-term dieting often make progress feel difficult. I believe sustainable change comes from combining medicine, lifestyle, and behaviour change techniques. My approach is safety-first, evidence-based, and focused on lasting wellbeing.
