Specialist corporate and commercial advisory, in one team

We have lived every side of the table

Selling, buying, raising or changing ownership? We start with the result you need, then bring the financial, legal and strategic work together to deliver it. The same senior team stays with you from the first decision through completion and the next stage.

Led by Matt Parry-Hann and Jamie Ritchie, who have been the owner, the investor, the adviser, the general counsel and the operator: lawyers at Jones Day, Addleshaw Goddard and Ashurst, a former Head of London at Wilsons, a former partner at IBIS Capital, and a chief executive who ran a business through its sale.

Why ON is different

We automate the grind, not the judgement.

Proprietary systems run the repetitive work, so senior time goes on the decisions. One team stays with you from start to finish. At scoping we tell you what it will do on your matter, and who is accountable for it.

Runs on our tooling

  • Data-room indexing and review lists
  • First-turn drafting from precedent
  • Disclosure and issue tracking
  • Model builds and version control
  • Buyer and investor long-lists
  • Status reporting and chasing

Stays with senior people

  • Structure and price
  • What to concede, what to hold
  • The call with the other side
  • The advice to the board

and deciding which is which

The seven seats

We have sat in each of them, which is why we know what the person opposite is about to say.

The same deal, seven seats. One team that has held every one.

Pay for our time, or pay for the result.

Hourly

Advice when you need it, at our standard rates. Partner rates are less than half those of a City firm.

Retainer

Time secured in advance, at a discount. Additional hours stay at the retainer rate until the work becomes its own project.

Success fee

A fee tied to the outcome, where aligning our interests with yours benefits everyone.

Practices

How we work with you

M&A advisory, corporate finance, shareholder and succession, strategic and operational, corporate and commercial legal, and AI and technology.

Call us before, not after.

Most clients call us when they have already begun their process, then tell us they wish they had called earlier.

A deal that starts without proper advice can leave money on the table, or need a structure unpicked before it can finish. Unpicking it costs more than the structure did.

The first conversation will add the most value.

Three ways from idea to living with it

Three ways to get there.

COSTTIMEsigningWhere you areThe dealWhere you are goingYou

Three ways from where you are to where you are going, against cost and time. ON from the start is the one line that carries on past signing.

Bring us the decision, even if the plan is unfinished.

A principal will help you work out what matters first. The earlier the call, the more we can add. The first conversation costs nothing.
