About NorthArc

Most US structuring mistakes are not wrong decisions.
They are right decisions made in the wrong order.

When NorthArc Becomes Relevant

Advice at the moments when structure begins to matter.

The trigger differs from company to company. The underlying question is the same: does the existing structure still support what the business is about to do?

01

Raising US investment

Understand whether the existing UK structure works for US investors and whether a reorganisation is genuinely required.
02

Establishing US operations

Decide where and how to establish, employ, contract and manage activity across the two countries.
03

Restructuring the group

Compare a UK parent, US parent, subsidiary or alternative route before committing to a structure that may be hard to reverse.
04

Relocating founders or senior employees

Consider the interaction between company structure, residence, equity, personal assets and future transactions.
05

Preparing for investment, diligence or exit

Ensure the structure, analysis and decision history can withstand scrutiny from investors, buyers and their advisers.

How We Help

Support from the first question through to implementation.

NorthArc helps founders, boards and investors understand the available routes, decide what should happen now, and coordinate the work across their UK and US advisers.

The result is a structure that supports the commercial objective without unnecessarily compromising what has already been built.

One Decision Across Two Countries

Everyone can solve their piece. Someone still needs to own the decision.

A UK accountant considers the UK tax position. A US lawyer establishes the entity. A payroll provider handles the employee. An investor expresses a preference.

Each may answer its part correctly without anyone owning the overall structure or the order in which it is built. NorthArc works across that boundary.

One Decision Across Two Countries

Everyone can solve their piece. Someone still needs to own the decision.

Cross-border decisions are often divided between several providers, each answering its part correctly without anyone taking responsibility for the overall structure or the order in which it is built.

NorthArc works across that boundary. We consider the commercial objective, the UK starting position, the US consequences and the sequence in which each decision should be made.

NorthArc does not replace your accountant or lawyer. We help establish the right direction before the individual parts are implemented.

Why NorthArc

Technical expertise, viewed from the founder's side of the table.

Commercial judgement

The technically available answer is not always the commercially appropriate one. NorthArc begins with what the company is trying to achieve.

Independent recommendations

NorthArc does not sell incorporations or a predetermined route. The recommendation may be to act, wait or retain the existing structure.

UK and US coordination

The UK and US questions are brought into one decision, with specialist providers coordinated where implementation is required.

Clear, defensible work

Recommendations are presented in straightforward language, with the analysis and evidence required by boards, investors and future advisers.

Information is everywhere. Judgement isn't.

Proof

See what people have to say

We had the privilege of a US angel coming on board, and immediately came the question of what US investment would actually mean — for us and for our existing backers. Everyone’s first instinct is to jump on the AI tools and figure it out, but you quickly realise there’s a whole load of information out there and no knowledge or wisdom. Stephen gave us that in spades: every scenario mapped, in plain English, with the wins and losses for an investor laid out on a single page. My expectations weren’t just met, they were well surpassed. When you’re moving fast and you’re not a big company with huge pots to spend, I don’t see why you’d go anywhere else.

I’ve known and worked with Stephen for the best part of a decade, and in that time he’s been my trusted partner on anything commercial, tax or finance related. What sets him apart is judgement — when something’s genuinely complex, he cuts through it, tells you straight what matters and what doesn’t, and gives you a clear path forward. I’ve never had to second-guess his advice. He’s the person I call when the stakes are high and I need the right answer, not just an answer.

The magic was the human-led, tech-enabled approach. speed, efficiency and transparency, with the most important thing still in the room: real expertise and trust. Our US advisor came onto a call unsure whether this was a goer, and you could see the pressure lift off his face. His words were, ‘I’m now laser focused on getting you fundraising in the US.’ NorthArc has given us the capability and capacity to enter one of the two biggest markets in the world with confidence and clarity. My advice to any founder: if the US is part of your growth plan and you’re even thinking about it, get in touch ASAP.
