Testronic has announced a series of high‑level appointments across its worldwide operations, underscoring the company’s commitment to strengthening its leadership and expanding its service capabilities. Among the most prominent additions is Mike Guttman, who has been elevated to the role of Vice President of Senior Partnerships. In this capacity, Guttman will be responsible for cultivating and managing relationships with Testronic’s most strategic clients, ensuring that the company’s offerings remain aligned with the evolving needs of the gaming and interactive entertainment sectors. Guttman arrives at Testronic with a robust background in client partnership and business development.
Prior to joining the firm, he spent several years at Keywords Studios, where he served as a client partner, directly overseeing large‑scale accounts and driving growth initiatives. He also held the position of senior business development manager, a role that sharpened his ability to identify market opportunities, negotiate complex contracts, and deliver value‑added solutions to a diverse portfolio of developers and publishers. His experience in navigating the intricate dynamics of the global gaming ecosystem makes him a natural fit for overseeing senior partnerships at Testronic.
Working alongside Guttman is Nicole Closson, who has been appointed Business Development Manager. Closson’s mandate is to broaden commercial coverage and provide additional support to partners both regionally and worldwide. She brings a wealth of experience from her previous tenure at Keywords Studios, where she excelled as an enterprise account executive, managing high‑value relationships and orchestrating multi‑project collaborations.
Before that, she contributed to Unity’s growth as a senior account executive for Parsec and SyncSketch, gaining deep insight into real‑time collaboration tools and cloud‑based streaming technologies. Her combined expertise in enterprise sales and technical platforms equips her to drive new business opportunities and strengthen existing client ties.
In the European hub of Warsaw, Testronic has promoted Mateusz Kałuża to the position of QA Director. Kałuża’s career trajectory includes senior testing roles at Lionbridge Games, where he honed his skills in quality assurance, test automation, and process optimization. In his new role, he emphasizes the city’s strategic importance: "Warsaw brings together deep QA expertise, experience and a real understanding of what developers need from a testing partner.
Our continued investment in the team ensures we grow that expertise locally, fully connect it with Testronic's wider global capabilities and deliver consistently for partners wherever they are based." Kałuża’s leadership is expected to reinforce the company’s commitment to delivering reliable, high‑quality testing services that meet the rigorous standards of modern game development. Further bolstering the global partnership team, Lily Guerreiro joins as Global Partnerships Senior Manager. Guerreiro’s prior experience includes a tenure as Global Business Development Manager at Keywords Studios, where she managed cross‑border initiatives and forged strategic alliances with leading publishers.
Her global perspective and proven track record in scaling partnership programs will be instrumental in expanding Testronic’s reach and deepening its collaborative relationships across continents. The Manila Centre of Excellence also sees senior talent added to its ranks. Daniel Bowie Soriano steps into the role of Senior QA Manager, bringing extensive hands‑on testing experience and a keen eye for process improvement. Complementing him is Ivan Balanay, who assumes the position of QA Trainer.
Balanay’s appointment is described as a move to "further support our investment in developing the Testronic Academy and building the next generation of QA expertise." In this capacity, he will design and deliver training curricula, mentor junior testers, and ensure that the Manila team remains at the forefront of emerging testing methodologies and tools. Chief Revenue Officer Michael Fitzgerald highlighted the strategic importance of these appointments, stating, "Our Centres of Excellence bring together talented people, specialist expertise and leadership, and connect those capabilities across a genuinely global organisation. The investments we are making in New Orleans, Warsaw and Manila, alongside our presence in London, further strengthen the expertise available to our partners.
By continuing to invest in outstanding people, we can deliver an exceptional Player‑Focused, Partner‑First and Outcomes‑Led service to our clients." Fitzgerald’s remarks underscore a broader vision: Testronic aims to blend localized expertise with a cohesive global network, ensuring that partners receive consistent, high‑quality support regardless of geography. The leadership reshuffle follows a recent change at the helm of the company.
Earlier this month, Sonia Kerr was appointed Chief Executive Officer, succeeding Sharon Baylay‑Bell, who transitioned to the role of company chair. This transition marks a new chapter for Testronic, positioning Kerr to steer the organization through a period of rapid industry evolution and heightened demand for sophisticated QA solutions. In addition to Kerr’s appointment, Testronic announced that Michael Fitzgerald would also serve as Chief Revenue Officer, while Samantha Williams took on the role of Chief Commercial Officer.
Fitzgerald’s background includes a stint as a client partner at Keywords Studios, providing him with a nuanced understanding of client expectations and revenue generation strategies. Williams, previously Testronic’s global CRO and head of Europe, brings a wealth of commercial acumen and regional market insight, which will be vital in driving growth across existing and emerging markets. Collectively, these strategic hires and promotions signal Testronic’s dedication to nurturing talent, expanding its global footprint, and delivering best‑in‑class testing services.
By integrating seasoned professionals with deep industry knowledge, the company aims to enhance its service portfolio, accelerate innovation, and maintain a competitive edge in an increasingly complex gaming landscape. The expanded leadership team is poised to foster stronger collaborations with developers, publishers, and technology partners, ensuring that Testronic remains a trusted ally in delivering flawless, immersive player experiences worldwide.
