The City of London · Est. 2023
Where value can be unlocked.
A London advisory house. Consulting and family office work across the UK, South Africa, Jersey, Mauritius and Switzerland. Private capital and a startup incubator through our sister company. AI last — after we have established what should not be done at all.
A London advisory house
A distinct note, on purpose.
A cowbell exists to be heard through weather, distance and the movement of the herd. The firm is built on the same idea: be distinct, and be useful — not fashionable.
Most of the value in a business is already there — in the books, the process, the people, the deal that has not been looked at hard enough. We unlock it. Twenty-five years in retail and investment banking is the instrument, not the brochure.
Cross-border

The London house. Advisory, family office and the City conversation.
South Africa
Banking, private capital, operating businesses and cross-border flows.
Jersey
Trusts, holding structures, capital that needs a Channel Island seat.
Mauritius
Africa-facing structures and the movement of capital.
Switzerland
Private-client, banking and family-office planning.
Four practices
What we do
I · Twenty-five years in the room
Advisory
Consulting that comes from retail and investment banking — due diligence, operating models, credit, the conversation after the slides.
ReadII · When the mandate is the whole house
Family office
Entities, trusts, succession and the operating businesses underneath — including for a large high-net-worth family. One practice, not the whole firm.
ReadIII · Not only a cheque
Private capital
Through sister house Exalt Capital we fund, incubate and build — including businesses started inside Exalt, not only ones we back.
ReadIV · Do not automate what you can remove
AI transition
Last, on purpose. For small and medium service firms that want the work redesigned — not a chatbot bolted onto a bad process.

The work
Banking judgement. Applied where it pays.
That includes financial due diligence — including for some of South Africa’s largest institutions. On other days it is a family office across Jersey and Mauritius, or a board that wants a number they can defend.
When a business also needs capital — or a place to be built — we do not pretend Cowbell is a fund. We take that work to Exalt Capital, our sister house: private equity, and a startup incubator with businesses started inside it.
About Jaco
Sister house
Exalt Capital builds, incubates and backs ambitious businesses.
Not only a cheque. Companies are started inside Exalt — venture studio, capital, and hands-on partnership. Jaco sits as a director of both houses.
