Testronic has announced a series of high‑level appointments across its worldwide operations, underscoring the company’s commitment to expanding its leadership bench and enhancing service delivery for clients in the gaming and interactive entertainment sectors. 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 strategic relationships with large‑scale partners, overseeing the development of collaborative initiatives, and ensuring that Testronic’s service portfolio aligns closely with the evolving needs of its clientele. Guttman arrives at Testronic with a robust background in client‑facing roles.
Prior to joining the firm, he spent several years as a client partner at Keywords Studios, where he managed a portfolio of high‑value accounts and helped drive revenue growth through tailored service offerings. He also held the position of senior business development manager, a role that sharpened his ability to identify market opportunities, negotiate complex contracts, and build long‑term partnerships.
His blend of strategic insight and hands‑on execution makes him well‑suited to steer Testronic’s senior partnership agenda. Supporting Guttman’s efforts is Nicole Closson, who steps into the role of Business Development Manager. Closson’s mandate is to broaden commercial coverage and provide dedicated support to partners both regionally and globally.
Her previous experience includes a stint as an enterprise account executive at Keywords Studios, where she managed large corporate accounts and delivered customized solutions that addressed client-specific challenges. She also served as a senior account executive for Parsec and SyncSketch at Unity, gaining valuable exposure to the broader ecosystem of interactive media tools and platforms.
Together, Guttman and Closson form a complementary duo focused on deepening client engagement and expanding Testronic’s market footprint. In the company’s Warsaw hub, Mateusz Kałuża has been promoted to QA Director after a distinguished tenure in senior testing positions at Lionbridge Games.
Kałuża highlighted the strategic importance of the Warsaw office, noting that the location "brings together deep QA expertise, experience and a real understanding of what developers need from a testing partner." He emphasized that continued investment in the local team will not only nurture home‑grown talent but also integrate Warsaw’s capabilities with Testronic’s global network, ensuring consistent delivery standards for partners worldwide. Further strengthening the global partnership function, Lily Guerreiro joins as Global Partnerships Senior Manager. Guerreiro previously held the title of Global Business Development Manager at Keywords Studios, where she was instrumental in forging cross‑border collaborations and scaling service offerings across multiple regions. Her expertise in navigating complex, multinational relationships will be pivotal as Testronic seeks to deepen its ties with existing partners and attract new ones.
The Manila Centre of Excellence also sees senior talent added to its ranks. Daniel Bowie Soriano has been appointed Senior QA Manager, bringing a wealth of experience in quality assurance leadership. Working alongside him is Ivan Balanay, who assumes the role of QA Trainer.
Balanay’s appointment is described as a move that "further supports [Testronic’s] investment in developing the Testronic Academy and building the next generation of QA expertise." The Academy aims to cultivate a pipeline of highly skilled testers, providing continuous learning opportunities and ensuring that the company remains at the forefront of industry best practices. Chief Revenue Officer Michael Fitzgerald commented on the strategic 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, together with 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 broader executive reshuffle earlier in the month.
Sonia Kerr was named Chief Executive Officer, succeeding Sharon Baylay‑Bell, who transitioned to the role of company chair. Additionally, Michael Fitzgerald was confirmed as Chief Revenue Officer, while Samantha Williams took on the duties of Chief Commercial Officer. Fitzgerald brings prior experience as a client partner at Keywords Studios, whereas Williams previously served as Testronic’s global CRO and head of Europe, positioning both executives to drive growth and commercial excellence. Overall, Testronic’s recent appointments reflect a deliberate strategy to reinforce its leadership talent pool across key geographic hubs.
By integrating seasoned professionals with deep industry knowledge and a track record of successful partnership management, the company aims to enhance its service quality, broaden its market reach, and deliver measurable outcomes for game developers and publishers worldwide. The expanded senior team is expected to accelerate the company’s growth trajectory, foster innovation in testing methodologies, and uphold Testronic’s reputation as a trusted partner in the interactive entertainment ecosystem.
