Our clients need advice and solutions that help them make smarter risk management decisions, respond to regulatory expectations, and build long-term confidence. The new structure gives us the clarity and focus to continue delivering that support, while further deepening our advisory, delivery and RiskTech capabilities,” said Josh Nowak, Chief Executive Officer, Katalysys (UK).

I look forward to building a strong US presence and delivering exceptional outcomes for our clients,” said Scott Arden, Chief Executive Officer, Katalysys (US).
Alvin Abraham, co-founder of Katalysys, will continue to support the business under the new structure, providing continuity, strategic input and senior expertise across client delivery, product development and the firm’s long-term growth agenda.
