Deloitte and Olympic Champion Daniel Wiffen join forces in game-changing four-year partnership
Deloitte Ireland has today announced a landmark four-year partnership with Olympic Champion and World Record Holder Daniel Wiffen, officially naming him the firm’s new lead brand ambassador.
The announcement was made during Wiffen’s visit to Deloitte’s Dublin headquarters on Global Olympics Day, and it marks the beginning of a high-performance collaboration designed to spotlight elite mindsets, data-led innovation, and an unrelenting pursuit of excellence, all values central to both Deloitte and Wiffen’s journeys.
This partnership brings together the world’s number one professional services firm and one of the world’s top-ranked athletes, united by a mindset that never stops challenging.
At just 23 years old, Wiffen has already carved out a place in history. A world champion and the first Irish male Olympic gold medalist in swimming, he recently clocked the second fastest 1500m freestyle time in the world this year at the Irish Open finishing more than thirty seconds ahead of the field. And he’s not slowing down.
Daniel brings an elite mindset to everything he does,
points out Harry Goddard, CEO of Deloitte Ireland.
It’s one driven by discipline, intelligence, and a constant search for improvement. What sets him apart is his approach: he uses data not just to understand performance, but to shape it.
His philosophy reflects ours here at Deloitte. Whether in the pool or in business, high performance is never accidental. It’s engineered through analysis, reflection, and action. We’re proud to support him as he builds toward LA 2028 and redefines what’s possible.
Metrics and Mindset
Wiffen’s training program integrates a suite of performance tools including 3D motion tracking, biometric analysis, velocity and acceleration data, and machine learning. It’s a feedback-driven system where nothing is left to chance, every decision is made based on measurable evidence and informed iteration.
Today’s announcement was marked by a virtual announcement to over 3,000 Deloitte staff across Ireland, a lunch session with Deloitte’s AI and Analytics leaders, and a roundtable interview with Irish and UK media outlets. Wiffen and some of the data team also discussed insights on how precision analysis can shape progress, from body position underwater to distance per stroke.
The partnership aligns with a pivotal moment in his career. With the World Championships in Singapore just weeks away, Wiffen is in peak preparation mode. That event will likely serve as a key platform for his next world record attempt.
His long-term goal is even more ambitious: to become a four-time world record holder and reach the pinnacle of the sport at the 2028 Olympic Games in Los Angeles.
Excellence is built.
explains Daniel Wiffen
Every training cycle, every split time, every recovery session is tracked, analysed, and improved. I use data to understand where I am and to see what I can be. It reveals things the stopwatch can’t, how fatigue shows up in my form, how I can gain efficiency on the turn, how small changes stack into real performance.
Working with Deloitte makes perfect sense. As the number one professional services firm globally, the team here understands that mindset of always challenging, always refining. Deloitte people are sharp, curious, and at the edge of what they do constantly. That energy drives me. I’m excited to take on this journey together toward more records, more growth, and a shot at LA 2028. This is just the beginning.
