I’ve built AI products inside hospitals, startups, and venture funds.

Most people building healthcare AI have never worked a night shift. I spent three years in the NHS across 10+ specialities before crossing over to build at a Khosla-backed startup, advise a $200M+ venture fund, and lead product at an AI company used by thousands of clinicians. I write about what I’m seeing — and I take a handful of advisory calls each week for founders and clinicians navigating this space.

The Path From Clinician to Builder

Four roles in four years. Each one taught me something the last one couldn’t.

England, UK

NHS Doctor

Practised across 10+ specialities — Cardiology, Acute Medicine, Trauma, Orthopaedics. Managed wards at 3am, led emergency responses, and learned firsthand where the systems clinicians depend on consistently fail them.

San Francisco, CA

Employee #1 · AI Health Startup

First hire at a Khosla-backed startup at $18M valuation. Led product for an AI cancer second-opinion platform. Directed ML models trained on 10M+ patient records. Built the patient site that ranked top 5 in ChatGPT search for cancer second opinions.

London, UK

VC Advisor · Global VC Fund

Clinical and technical advisor to a global fund with $200M+ deployed. Led due diligence on seed-stage AI companies. Flagged a critical clinical flaw that changed the fund's view on a $1B+ market claim.

Doha, Qatar

Chief of Operations · Rhazes AI

Leading ops, product, and commercial strategy for an AI copilot that thinks with doctors, not instead of them. Thousands of daily active clinicians, seed fundraising underway, and building the European regulatory pathway via SaMD.
