Professional Journey

Fahey’s background is in building technology for financial institutions; MCO credits him with more than 30 years of experience delivering complex solutions to financial services firms worldwide. MyComplianceOffice took shape inside Fidelity Investments, within a division called TerraNua. The company’s own accounts date its origins differently: its timeline says the product was created there in 1998, while Fahey has described MCO as starting as a concept in 2006, when the core team was still part of Fidelity.

The two accounts agree that 2008 is the turning point. That year MCO left Fidelity under Fahey’s leadership, with the aim of building a single compliance platform in place of manual processes and siloed systems. For its first five years the company sold SaaS employee-compliance tools to small and mid-market firms in the United States from its Dublin headquarters, opening a New York office to support those customers. From 2013 it added third-party and transactional compliance and began selling to larger institutions.

MCO now sells what it describes as 30 products on a single system and lists offices in New York, Fort Worth, Chicago, London, Singapore and Hyderabad alongside Dublin. Fahey received two CEO awards in consecutive years: Large Business CEO of the Year at the Business Post Leadership Excellence Awards in November 2024, and Best FinTech Company CEO in the FinTech Breakthrough Awards in March 2025, where the citation said he had taken MCO from a small niche player to a global enterprise company.

In September 2026 MCO announced strategic growth financing of more than $100 million from Accel-KKR Credit Partners, to be used for product and AI development and market expansion. Fahey said the company would use the investment to change how client firms use technology to run their compliance programmes. The announcement describes financing, not a sale, and the company still calls itself privately held and founder-led.
