He merged a bank in Doha, then built homes in Portugal, then bought a coffee roaster. The thread is simple: capital that shows up and stays in the room.
In January 2025 a new company appeared on the UK register: Sovereign Stone Capital Partners Limited. The founding partner listed is Ateeq ur Rahman, British, born November 1970, resident in England. Six months later he added two more directorships - SSCP Roasting and Roasting Party Retail. A capital partnership and a coffee roaster, signed within half a year of each other. That pairing tells you most of what you need to know about how he works.
Sovereign Stone exists on a single conviction: mid-market businesses in the UK and Southern Europe are underserved by traditional capital providers. The firm sets out to bridge that gap - not as a passive backer, but as a partner who brings strategic rigour, operational muscle, and an international address book to every deal. He commits his own money to each transaction. The alignment is the point.
That instinct was earned. Before the firm, there were nearly three decades inside banking across the Middle East, Europe, and Asia. He worked the syndicated and structured finance desks, ran project finance, and stood up Islamic corporate banking divisions from a blank page. The deals were not small: energy, telecom, textiles, steel, the kind of multi-billion-dollar transactions that move a country's GDP figures a little.
The headline chapter is Qatar. As Country Head and Managing Director for Abu Dhabi Commercial Bank, he led the merger with Union National Bank - one of the more consequential consolidations in Gulf banking. Merging two banks is not a spreadsheet exercise. It is people, regulators, systems, and ego, all at once, and someone has to keep their hand steady. He did.
Then he changed seats. The man who had financed other people's projects started building his own. He founded the Venture 40 Fund, which was later spun off. He became CEO of Visao Unica, a prime residential real estate developer in Portugal, swapping term sheets for blueprints. He joined the board of RUI Holdings and the investment committee of the Serra Stone Portugal Fund. The Iberian pivot was deliberate - Southern Europe is exactly the underserved territory Sovereign Stone now targets.
And then, coffee. The 2025 director seats at SSCP Roasting and Roasting Party Retail moved the investment house straight into the cup. It is the least obvious line on his record and maybe the most revealing. He does not collect industries for the logos. He buys into businesses he intends to help run, whether they pour espresso or pour concrete.
The education reads like the rest: an MBA in Finance and the Harvard Business School Executive Development Program. Credentials that open doors he then walks through to do the unglamorous work on the other side.
What you are catching, mid-stride, is a financier who decided that writing the check was the easy part. The harder, better part is staying.
“Mid-market businesses deserve more than passive capital.”
