ABOUT OXYGEN
Built by senior practitioners. Backed by a production AI platform.
A Financial Services consultancy specialising in capital-markets Operations. We work with Operations leaders across the journey to an AI-First Operating Model — from understanding the implications, to finding where to start, to running it at scale.
OPERATIONS IS IN OUR DNA
Why we exist.
Oxygen was founded with a clear goal: provide the Financial Services industry with a centre of excellence specifically focussed on Operations. Operations practitioners, methodologies and frameworks that reduce cost & risk, and improve efficiency & quality.
Headcount-led operating models are unsustainable. The industry is moving to AI-enabled Operations — and the firms that get there first will run leaner, more reliable, more accurate operations than headcount-led competitors. Oxygen exists to help capital-markets Operations leaders make that transition.
We bring 25+ years of post-trade operating experience, industry-grade methodologies, and — through our partnership with Gentek.ai — a production agentic platform built specifically for capital markets.

Karl Wolohan
Managing Partner
Twenty-five years in Financial Services, the last sixteen at Markit / IHS Markit / S&P Global, where Karl was MD, Global Head of Operations and acting COO for the MarkitSERV business — board member and director of the FCA-regulated entity, leading global Operations across critical post-trade infrastructure.
Earlier career in Investment Banking (Citi, DRKW) covering core account management, transaction control and financial compliance. Chaired industry working groups on Credit market transformation. Founded Oxygen to champion Operations as a strategic function and an industry priority — and to help senior leaders navigate the move to AI-First Operating Models.

OUR PARTNER

Oxygen partners with Gentek.ai for production-grade agentic AI in capital markets.
The partnership splits the work along the line we believe matters: Oxygen provides the practitioners — the people who know capital-markets Operations, the regulatory taxonomy, and how programmes actually run under pressure. Gentek provides the platform — vertical agents trained on financial-services data, production-deployed, supplied through the partnership.
One contract. One accountable team. No vendor seam between strategy, build, and run.
HOW WE WORK
Four principles. Shared with every client.
How we do business is as important as the actions we take. These are the standards we hold ourselves to, on every engagement.
