Q5 names Amanda Lewis as chief financial officer

Amanda Lewis has joined Q5 as the firm’s new chief financial officer. She will take on the role as the firm looks to push ahead with a global growth journey across four continents.

Olly Purnell, managing partner at Q5, commented, “It’s wonderful to have Amanda on board. She inherits an excellent Finance team, but will bring experience and commercial finance nous and leadership that will hopefully enable us to be more global in the way we approach things.”

Founded in 2009, Q5 is a consulting firm which helps clients develop strategy, and deliver organisational change. The firm has more than 300 specialists stationed across offices in London, Leeds, Cardiff, Sydney, Melbourne, Hong Kong, Houston, New York, and Riyadh.

According to the firm, Q5 has doubled in size between 2020 and 2025. Looking ahead, Lewis will work closely with the leadership team to build on that across Europe, the Middle East, North America, and Australia. As chief financial officer at Q5, she is responsible for shaping and executing the company’s strategy of doubling in size again by 2030, without losing sight of the firm’s sustainability goals.

She brings more than two decades of experience as a transformative finance leader, and was most recently the chief financial officer at The Chemistry Group. She helped the business through an M&A process, attracting top-tier talent to help move the company into its next phase of growth. She also played a key role in fostering a culture of data transparency, facilitating strategic insights, improving operational efficiency, and aligning cost structures with financial targets.

Speaking on her new role, Lewis added, “I am thrilled to join the Q5 team and be part of an award-winning firm that is helping to build better businesses across the world. I’m passionate about driving client and partner success, while also coaching and mentoring a team to create a high-performing environment. I look forward to the growth we can achieve together.”
