About the founder

Harry Breach

Founder, Finewell Street Capital.

I've spent my career on the other side of the table from most acquirers — analysing, valuing and understanding businesses rather than simply buying them.

For over 20 years, I worked as an Aerospace & Defence equity research analyst across some of the City's leading investment banks, including JP Morgan, Bank of America, Barclays and others. In that time, I covered the sector's biggest names — Airbus, Boeing, Lockheed Martin, Northrop Grumman, General Dynamics, Raytheon, BAE Systems, Rolls-Royce, Thales, Safran, MTU Aero Engines, Dassault Aviation, Leonardo — and dozens of the specialist suppliers that sit beneath them in the supply chain. I've built financial models, sat in management meetings and Q&A sessions, and tracked what genuinely separates a resilient, well-run, long-term business from one that simply looks good on paper.

Alongside that, I co-founded and served as CFO of ChargeSync, a software technology business built from the ground up — which taught me, first-hand, what it actually takes to grow a company, manage cash, lead a team, and make the calls that analysts on the outside rarely have to make themselves.

I set up Finewell Street Capital to bring those two perspectives together — two decades studying what makes Aerospace & Defence businesses strong and valuable, and direct experience building a company of my own — and to put that experience into acquiring and growing businesses directly, working closely with the owners and teams who built them.

Why I do this

Many of the best businesses in this sector were built by engineers and entrepreneurs who never intended to be professional dealmakers. They built something excellent — one product, one service, one contract and one customer at a time. When the time comes to think about the future, they deserve a buyer who understands the industry, respects what's been built, and won't disappear the moment the deal closes.

That's the role I want to play: a single point of contact, a genuine sector specialist, and a long-term custodian — not a faceless fund.

I read Law at the University of Oxford before moving into financial services. I remain engaged with the UK Aerospace & Defence community, and I'm a firm believer that culture, leadership, far-sightedness and customer relationships matter every bit as much as the numbers on a P&L or a Balance Sheet — because in my experience, they're usually what the numbers are quietly telling you.

If you're an owner thinking about what comes next, I'd welcome a conversation with no obligation and no pressure — just an honest discussion from someone who properly knows this industry.
