Who We Are

A global financial &
business advisory
firm.

The Arc is a global financial and business advisory firm founded by three Chartered Accountants who share one conviction: the best advisory work lives at the intersection of deep technical expertise and genuine intellectual curiosity.

All three founding directors hold the Chartered Accountant designation in Ghana. Two are also Chartered Tax Practitioners. All three are current doctoral researchers at leading universities in the United States — bringing the discipline of academic rigour to every client engagement.

We are not a large firm trying to be boutique. We are a focused practice that delivers work of exceptional quality, on every engagement, for every client.

01
Precision
Every number, recommendation, and word is exact. We do not approximate when accuracy is available.
02
Integrity
We advise honestly, even when the truth is difficult. Our value lies in what we say, not only how we say it.
03
Impact
We measure success by what changes — for our clients and the institutions they lead.
04
Ambition
We operate with a global mindset while remaining deeply connected to the contexts we serve.

How We Work

Our methodology is
deliberately sequential.

Every engagement moves through three stages. They are not interchangeable. The sequence matters — because the quality of what comes later depends entirely on the rigour of what came before.

01
Analyze

We start by examining everything — data, structure, opportunity, risk, and context. With the discipline of doctoral researchers and the sharpness of Chartered practitioners, we leave no assumption untested. The analysis we produce is the foundation on which everything else is built.

02
Advise

We interpret the findings and translate complex insight into clear, prioritised, actionable guidance. Our advice is direct, honest, and always grounded in evidence — never in what you want to hear. We say what others are reluctant to say, because that is where the real value lies.

03
Accelerate

We stay with you through execution — tracking outcomes until the change is real and the results are verifiable. Acceleration is not speed for its own sake. It is purposeful momentum: the right moves, in the right order, at the right pace. That is The Arc difference.

FAQ

Questions we
get asked often.

What types of clients does The Arc work with? +
The Arc works with a broad range of clients — from growing small and medium-sized enterprises seeking financial clarity, to large corporations requiring strategic advisory, to government institutions and non-profits needing rigorous analysis and compliance support. We serve clients globally, with particular depth of experience across Africa and North America.
How does The Arc approach a new client engagement? +
Every engagement begins with a discovery conversation — we listen first. We then apply our three-stage methodology: Analyze, Advise, Accelerate. We examine your situation with rigour, deliver honest and precise recommendations, and stay engaged through implementation to ensure the results are real and measurable.
Are your directors qualified to handle international engagements? +
Yes. All three founding directors are Chartered Accountants registered in Ghana and are currently pursuing doctoral research at leading universities in the United States — Texas Tech University and The University of Alabama. This positions The Arc uniquely to deliver advisory work that is locally grounded and globally benchmarked, drawing on both professional practice and academic rigour.
How long does a typical advisory engagement take? +
Engagements vary depending on scope and complexity. A focused tax advisory or financial review may take two to four weeks. A full business strategy or restructuring engagement typically runs between one and six months. We discuss timelines openly at the outset and structure our work to deliver value at every stage — not just at the end.
Does The Arc offer ongoing retainer arrangements? +
Yes. Many of our clients choose to retain The Arc on an ongoing basis for continuous financial oversight, monthly bookkeeping and management accounts, tax compliance, and strategic advisory. Retainer arrangements give clients direct access to our expertise without the cost of a full-time executive team — a highly efficient model for growing organisations.
How do I get started with The Arc? +
Simply reach out via the contact form on this page or email us directly at info@thearc.global. We will schedule an initial consultation — at no cost — to understand your needs, discuss how we can help, and outline a proposed approach. From there, we move as quickly as you need us to.
