Why now

Successful entrepreneurs and their families are usually well banked — but often badly advised or supported.

Successful entrepreneurs have easy access to a panel of consultants and advisors. What they often lack is someone who sees the whole picture, thinks like them and always works in their best interest – someone they can trust fully.

Wealth locked in operating businesses

First-generation families across Africa and the Gulf hold their wealth inside companies — with no consolidated view, weak governance and no succession plan.

Advice is fragmented

Consultants see the business, or part of it. Banks see the portfolio. Fiduciaries see the structure. Nobody sees the whole picture — or takes accountability for it.

The founder and the business are inseparable

Advising the company without advising its owner — and vice versa — leaves value on the table. Families feel this gap and ask their most trusted adviser to fill it.

Our market: families with USD 20–300m of business-centred wealth, across Dubai, Mauritius, East and West Africa.

Our model

One firm. Three pillars.

A client can enter through any door — advisory, family, or structure — and stay for all three.

1

Corporate Advisory

Transformation, re-engineering, governance, ESG, financial modelling, investment and scalability readiness, valuation and fundraising support — for SMEs and family businesses.

2

Private Clients & Family Office

The personal affairs of founders, directors and senior executives: trusts, wealth protection, succession, exits — with wealth management via vetted partners.

3

Structuring & Administration

The engine: structuring advice, company formation and ongoing administration and accounting across the UAE and Mauritius.

Advise the business. Protect the family. Administer the structure.

What each pillar covers

The full spectrum, under one roof.

Led jointly: strategic and financial advisory by partners business families already call for advice; transformation, governance and ESG delivery led by partners who have built 15+ businesses, chaired listed boards and driven transformation across African markets.

Why three pillars

Each pillar opens the door to the next.

A client can enter through any pillar. Advisory work surfaces the founder's personal needs; family mandates require structures; every structure needs administration, governance, risk management.

Our value proposition

Why families choose us.

01

Corridor fluency

Onaha partners are Mauritian, with careers spanning Mauritius, Dubai, Kenya, Tanzania, Rwanda, Côte d'Ivoire, Ghana and pan-African markets. We are at home in the boardroom in the DIFC/MIFC and in the family compound in Eastern or Western Africa.

02

Trust that travels

Clients repeatedly tell us they work with the person, not the firm. Onaha partners have built their 20+ year careers on that trust — and this firm is engineered so it scales beyond any one of us.

03

Whole-picture accountability

We advise the business, protect the family and run the structures. One relationship, one accountable partner — not three vendors pointing at each other.

04

Independence by design

No investment products to sell. Wealth managers are selected, benchmarked and monitored on the client's behalf, with every fee disclosed.

The people behind Onaha

A firm built on direct experience, not delegated advice.
