About

Ops clarity at the moment
it matters most.

I'm a fractional operator and chief of staff working exclusively with early-stage healthtech companies. I partner with founding teams at the point where things are moving fast, the team is growing, and the operational foundation hasn't kept pace — typically from pre-seed through Series A.

My background spans [placeholder: prior roles or industries], which means I bring both the strategic perspective and the hands-on execution capability that small teams actually need. I don't just advise — I build. Hiring processes, operating cadences, vendor relationships, financial workflows: I put the scaffolding in place and make sure it holds.

I typically work with up to five companies at a time, which means the relationships are close and the work is genuinely embedded. If you're a healthtech founder who needs an operator in the room — not a consultant on the sideline — I'd like to hear from you.

Four ways I make
founding teams faster.

Building ops from scratch (0→1)

Most early healthtech teams reach a point where the informal ways of working that served them in the first year start to break. I design and implement the operating infrastructure — from tooling and process to team norms — that lets a company scale without losing its speed.

Chief of staff & founder leverage

I act as a strategic right hand to the CEO or founding team: preparing for board meetings, synthesising information across functions, owning cross-functional projects, and making sure the things that matter don't fall through the cracks.

People & talent infrastructure

Hiring well at speed is one of the hardest things an early company has to do. I build the processes, scorecards, and candidate experience that let teams grow deliberately — and I help founders think carefully about the roles they actually need next.

Regulated-sector navigation

Health is a complex, regulated environment with real operational consequences for getting things wrong. I help teams build processes that are both agile and compliant — whether that means clinical governance, data handling, or commissioner-facing reporting.

Selected work

A few engagements
in detail.

Clerkenwell Health

[Placeholder headline — e.g. "Standing up ops for a first-of-kind clinical trial network"]

[Placeholder: 2–3 sentences describing what was done. E.g. — Embedded as fractional COO during a period of rapid headcount growth. Designed and implemented the company's core operating processes across finance, HR, and clinical operations. Owned the board reporting cycle and built the internal infrastructure to support a Series A raise.]

Vital Clinical Solutions

[Placeholder headline — e.g. "Bringing operational discipline to a high-growth clinical staffing platform"]

[Placeholder: 2–3 sentences describing what was done. E.g. — Joined as fractional chief of staff at a moment of significant commercial traction but limited operational bandwidth. Rebuilt the hiring process, introduced a quarterly planning rhythm, and established the supplier and compliance frameworks needed for regulated-sector contracts.]

[Placeholder outcome — e.g. "Time-to-hire reduced by [X]%; first NHS framework contract secured within six months of engagement start."]

Let's talk about
your company.

I take on a small number of engagements at a time and am selective about fit. If you're building something in healthtech and need an operator, the best first step is a short conversation.
