Jon O’Donnell has been appointed chief executive of Acuity Analytics, two years after joining the financial services research and analytics business as chief operating officer.
Jon takes over from Rob King, who will become chairman at the end of 2026.
Before joining Acuity Analytics in 2024, Jon spent more than 20 years at IBM, holding senior leadership positions across its consulting operations.
His responsibilities included leading business and technology consulting divisions across Europe, the Middle East and Africa, overseeing operations employing up to 15,000 people and generating approximately $3 billion in annual revenue.
He also served on IBM Consulting’s global leadership team.
Since joining Acuity Analytics, Jon has worked alongside the executive team on business strategy, technology development and the expansion of its data and artificial intelligence capabilities.
His appointment comes as the company develops its international operations and builds on recent acquisitions, including US data consultancy Continuus in October 2026.
Rob King, who has led the business through its separation from Moody’s and subsequent growth, will take over as chairman from Philip Gore-Randall.
Philip is retiring on 31 December after seven years in the position.
Jon’s promotion forms part of the company’s leadership succession plans, with Rob remaining involved in selected investor and client relationships.
The appointment marks the next stage in Jon’s career following more than two decades at IBM and two years in Acuity Analytics’ senior management team.
