“Building relationships to solve complex problems and drive growth.”

Based at our AAB Dublin office, Director Jack O’Donnell has valuable experience in supporting businesses across a wide range of industries with complex commercial and financial challenges. 

After gaining experience in a healthcare SaaS environment, where he developed an understanding of high-growth, data-driven decision-making, Jack now works closely with businesses across a range of sectors to help them make better decisions and achieve successful outcomes. 

With an analytical, positive approach to problem-solving, commercial awareness and strong communication skills, Jack sees beyond the number. This has helped him build strong client relationships based on trust, transparency and clear communication.

Not for Profit & Education. 

A Desire to Help Businesses Succeed

“I was inspired to pursue a career at AAB after working in a fast-paced healthcare SaaS environment, where I was exposed to high-growth, data-driven decision-making. 

I can apply the skills I have developed to businesses across different sectors and industries, helping them scale, adapt and succeed with confidence.”

Understanding Client Goals, Challenges & Progress

“My day-to-day role is varied. It includes supporting CFO engagements across a range of clients and helping solve complex commercial and financial challenges. 

I also collaborate with internal teams across tax, audit and consulting to deliver integrated solutions, while attending regular client meetings to better understand their goals, challenges and progress. 

By staying close to my clients, I can identify client needs, anticipate potential issues and ensure we continue to deliver value while supporting their wider objectives.”

Strong Relationships Built on Trust & Transparency

“Trust and transparency are key to building a strong relationship. I invest time upfront to get to know clients, understand their businesses and gain insight into their goals, challenges and priorities. 

As a Director, the most satisfying part of working with clients is developing long-term relationships and becoming their trusted advisor. I also enjoy supporting clients through challenges and seeing the results of effective collaboration. It is especially rewarding to see clients achieve successful outcomes and grow their businesses.” 

Navigating Challenges & Complex Problem Solving

“One of the most valuable lessons I’ve learnt is how to navigate rapid change in a growth SaaS environment. 

Through that experience, I learned that strong relationships and clear communication are essential during times of uncertainty. 

Challenges in my specialist area often involve problem-solving and simplifying complex financial information for clients in a way that is clear, relevant and actionable. Doing this well helps build trust quickly, especially with new clients, and supports successful, long-lasting relationships.” 

Finance Goes Beyond Numbers  

“A common misconception about my profession is that finance is only about numbers. I believe finance is just as much about the people behind the business. By building strong human relationships with clients, I can help businesses make better decisions.”

ADDING VALUE THROUGH COLLABORATION  

“The most rewarding aspect of being part of my team and the wider AAB organisation is the strong team culture, which values collaboration and relationships. I also value the opportunity to build and maintain strong client relationships across a wide range of industries. 

Relationship building, stakeholder management and strong analytical thinking are key strengths I bring to my role, enabling me to work closely with clients and colleagues to deliver meaningful outcomes. 

As I continue to develop my career, I’m looking forward to building on these strengths through further specialisation in advanced data analytics, visualisation, CFO advisory and strategic partnering, ensuring I can continue to make a positive impact for clients.”
