Vital in ensuring that the team behind this operation continue to work to the highest possible standards, CEO Oluseye Olusoga does more than simply oversee the firm’s direction, he also delivers strategic leadership and takes a very hands-on role when it comes to managing the many different facets of Parthian Partners. Understanding needs and traversing challenges, Oluseye is especially talented when it comes to balancing risks and opportunities, formulating effective strategies to empower his team at every turn.

Guided by the simple philosophy of doing whatever it takes to make the customer happy, the journey that Oluseye has been on throughout his professional career has proven invaluable in shaping this approach. A graduate of the UK’s Warwick Business School at the University of Warwick, Oluseye begin his career as an investment banker, before moving to Citi as a trader and finally to Parthian Partners in 2012. This experience, combined with his stellar academic credentials, makes Oluseye a tenacious and driven executive.

When it comes to his employees, Oluseye recognises the differences between leading a small team and a larger organisation. With Parthian Partners having undergone significant growth in the 13 years since Oluseye first ascended to the top of the company’s operational ladder, this is a CEO well versed in both of these areas. Be it effectively delegating responsibility amongst middle management or promoting a culture of accountability, Oluseye demonstrably has what it takes to keep his employees satisfied.

“I believe in a collaborative leadership style – one that encourages open dialogue, fosters a culture of continuous learning, and prioritises both individual and collective growth”, says Oluseye when asked about his approach to managing the firm. “Over the years, I have become more focused on developing future leaders within the organisation, ensuring that the company remains strong and adaptable regardless of external pressures.”

Our rapidly changing world is seeing these pressures mount significantly, especially when it comes to global politics and technological advancements. These changes are already starting to make themselves felt in this space, meaning that Oluseye and his team have to be prepared for anything. It is for this reason that this fintech innovator and economic thought leader has devised a future-proof strategy focusing on continuous learning, building strong alliances in the industry, and staying one step ahead of the curve.

Finally, when it comes to his own career, Oluseye signs off by telling us: “For me, success is not just personal – it’s about enabling others to succeed as well. My goal is to empower the people I work with, helping them to achieve their full potential. My greatest success lies in witnessing the growth and flourishing of those I’ve mentored and invested in.”

A selfless, talented, forward-looking financial services CEO, it is our pleasure to celebrate Oluseye Olusoga by naming him the Most Influential CEO 2025 – Capital Markets (Nigeria).
