Testronic has announced a series of high‑level appointments across its worldwide operations, most notably naming Mike Guttman as Vice President of Senior Partnerships. Guttman arrives with a robust background in client relations, having previously held the role of client partner at Keywords Studios and serving as a senior business development manager. His experience in nurturing strategic relationships and driving growth is expected to enhance Testronic’s ability to deliver tailored solutions for its diverse client base.
Supporting Guttman in expanding the company’s commercial reach is Nicole Closson, who joins as Business Development Manager. Closson’s mandate is to broaden commercial coverage and provide additional support to partners both regionally and globally. Prior to this appointment, she built a solid track record at Keywords Studios as an enterprise account executive and later at Unity, where she acted as senior account executive for the Parsec and SyncSketch products. Her deep understanding of enterprise sales cycles and her familiarity with the gaming and interactive media sectors position her to effectively bridge gaps between Testronic’s service offerings and client needs.
In the European hub of Warsaw, Testronic has promoted Mateusz Kałuża to the role of QA Director. Kałuża brings extensive experience from senior testing positions at Lionbridge Games, where he honed his expertise in quality assurance processes for complex, large‑scale projects. Speaking about the strategic importance of the Warsaw office, Kałuża noted, "Warsaw combines profound QA know‑how, practical experience, and a genuine grasp of what developers expect from a testing partner. Our ongoing investment in the team allows us to deepen that expertise locally, integrate it seamlessly with Testronic’s global capabilities, and consistently deliver value to partners wherever they operate." Further strengthening the global partnership team, Lily Guerreiro has been appointed Global Partnerships Senior Manager.
Guerreiro previously served as Global Business Development Manager at Keywords Studios, where she oversaw cross‑border initiatives and cultivated relationships with major publishers and developers. Her global perspective and proven ability to manage multi‑regional accounts will be instrumental in aligning Testronic’s services with the evolving demands of the worldwide gaming market. The Manila Centre of Excellence has also seen senior talent added to its ranks. Daniel Bowie Soriano steps in as Senior QA Manager, bringing a wealth of technical expertise and leadership experience to the team.
Alongside him, Ivan Balanay has been named QA Trainer, a role that underscores Testronic’s commitment to nurturing the next generation of quality assurance professionals. The company highlighted that Balanay’s appointment "further supports our investment in developing the Testronic Academy and building the next generation of QA expertise," emphasizing the strategic focus on education and skill development within the organization. Chief Revenue Officer Michael Fitzgerald emphasized the broader significance 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." He added that the recent investments in New Orleans, Warsaw, and Manila, in addition to the established 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." These leadership changes come on the heels of a major executive reshuffle earlier in the month, when Testronic announced the appointment of Sonia Kerr as Chief Executive Officer, succeeding Sharon Baylay‑Bell, who transitioned to the role of company chair.
Alongside Kerr’s promotion, Michael Fitzgerald was confirmed as Chief Revenue Officer, and Samantha Williams was named Chief Commercial Officer. Fitzgerald previously worked as a client partner at Keywords Studios, while Williams held the position of Global CRO and head of Europe at Testronic, bringing deep institutional knowledge to her new role. Collectively, these strategic hires and promotions signal Testronic’s intent to reinforce its global footprint and enhance its service delivery model. By integrating seasoned professionals with proven track records in business development, quality assurance, and partnership management, the company aims to provide a more cohesive, responsive, and high‑quality experience for its clients.
The focus on developing talent through initiatives like the Testronic Academy also demonstrates a long‑term commitment to building internal capabilities that can adapt to the rapidly changing landscape of game development and interactive media. In summary, Testronic’s recent senior appointments across its New Orleans, Warsaw, Manila, and London locations reflect a concerted effort to deepen expertise, expand commercial reach, and foster a culture of continuous improvement. With leaders like Mike Guttman, Nicole Closson, Mateusz Kałuża, Lily Guerreiro, Daniel Bowie Soriano, and Ivan Balanay now steering key functions, the company is well positioned to meet the growing and diverse needs of its partners worldwide, delivering on its promise of player‑centric, partner‑first, and outcomes‑driven services.
