Build optionality, maximise value, and reduce risk — before a deal forces your hand
“Without Mark leading the charge, I’m not convinced we would have got over the line”
Independent, founder-side support at every stage
Whether you’re actively considering a sale, planning to sell in the next 12 to 36 months, looking to de-risk your position, or building a more valuable, less founder-dependent business — we provide the strategic clarity and practical support you need.
From early exit planning to deal execution, we combine one-off diagnostics with ongoing founder-side support to make sure you pursue the right deal, on the right terms, at the right time for you
Strengthen the things that influence price, confidence, and negotiation leverage
Identify issues buyers will challenge before they become expensive problems
Make confident decisions with a clear process and the right support around you

Understand where the business stands today, what buyers will notice, and what needs attention first
Focus on changes that reduce risk, improve value, and make your business more sale-ready
Move into decision support, buyer conversations, diligence, and completion with clear founder-side advice
Most owners meet two separate worlds on the way to a sale: the adviser who helps them prepare, and the firm that runs the deal. The handover between the two is where preparation gets lost — the sell-side industry says so itself, and calls it the disconnect. The adviser who knew the business leaves the room just as the stakes rise.
We built our services so you never cross that seam alone. The same founder-side adviser who assessed your business and worked the preparation stays with you through the decision, the offer, the diligence and the completion — alongside your existing team. Nothing is re-learned at the moment you can least afford it.

Some firms make the opposite case: put corporate finance, tax and legal under one roof and alignment looks after itself. It’s a fair argument, and the convenience is real.
Here is ours. The specialists who serve your deal best are rarely all in one building — and a house that earns from every part of your transaction has one interest running through all of its advice. We keep the roles separate on purpose. Your tax adviser, your solicitor and (where appropriate) your corporate finance firm are chosen for your deal, each the right one for it, each under their own regulation. And beside you sits one adviser whose counsel on whether to sell — and whether to take the offer in front of you — is never paid on the deal happening: no mandate, no house to feed. Alignment, in our experience, comes from that seat being genuinely yours.
