Testronic appoints Sonia Kerr as CEO, Sharon Baylay-Bell becomes company chair

Testronic has appointed Sonia Kerr as CEO, succeeding Sharon Baylay-Bell, who moves into the role of company chair.

Kerr previously served as chief financial officer at XR Games and has experience in “leading high-growth digital businesses through transformation and expansion.”

During Baylay-Bell’s tenure as CEO, she led Testronic through a transition period that included expanding its global Centres of Excellence, introducing a new brand identity, and implementing its ‘Player-Focused, Partner-First, and Outcomes-Led’ strategy.

Testronic has also named Mike Fitzgerald as CRO and Samantha Williams as CCO.

Wallen was previously a client partner at Keywords Studios, joining as senior business development manager in 2018.

Williams joined Testronic in 2025 as a strategic advisor, becoming CRO then global CRO and head of Europe.

Earlier this year, Mike Wallen was appointed president and main board director of the company.

Testronic’s executive leadership will support its “long-term strategy of investing in specialist expertise across its Centres of Excellence in Warsaw, Manila, and New Orleans” to enable “consistent, scalable, and player-focused delivery for client partners.”

“Testronic has built an outstanding reputation as one of the most trusted QA partners in the global games industry,” said Kerr.

“What immediately stood out to me was not only the calibre of the business and its expertise, but also its culture, its people and its genuine passion for helping clients create incredible player experiences.

“The games industry is evolving rapidly, creating exciting opportunities for businesses that combine technical excellence with true partnership. Testronic is perfectly positioned to lead that evolution.”

Kerr continued: “I’m delighted to be joining the company and look forward to working alongside our talented teams, our clients and our partners as we continue to innovate, grow and help deliver outstanding games to players around the world.

“Together, we will continue empowering the next level in play and advancing on our vision to lead the world in making games incredible.”

Baylay-Bell added: “It has been an enormous privilege to lead Testronic through one of the most exciting periods in our history. Together, we have transformed the business, expanded our global capabilities, refreshed our brand and established a clear vision centred around care, expertise and delivering outstanding outcomes for our partners.

“As I move into the role of company chair, I do so with tremendous confidence in both Sonia and the executive leadership team we have assembled. Sonia is an exceptional leader with an outstanding track record of guiding ambitious businesses through growth and transformation. I know she will build on everything we’ve achieved and lead Testronic into an exciting new era.”
