Katerina Hayes brings a background most investors don't have: she came up servicing oil rigs for Maersk, TAQA, and Shell and worked on major projects like Sakhalin-1 and Sakhalin-2 before moving into venture investing, which gives her real credibility with industrial and Gulf operators, including contacts at Shell Energy Iraq, Aramco/WA'ED, Mubadala Energy, and QFCRA. Beyond her fund Scaler, she's built a wider group of ventures around one idea—that infrastructure and real relationships matter more than product alone—and she funds SettleX, a social enterprise helping displaced people rebuild their lives through entrepreneurship, a cause shaped by her own family's displacement and move to Scotland in 2022.

Scaler Capital is a venture fund focused specifically on post-MVP deeptech, applied AI, and data infrastructure for energy and industrial operations in the UAE, Saudi Arabia, Oman, Qatar, and the wider MENA region, led by Managing Partner Katerina Hayes, who spent 17 years in offshore oil and gas operations, and partner Olga Bertosh, an ACCA accountant with CFO and board-level governance experience.
