Testronic has announced a series of high‑level appointments across its worldwide operations, underscoring the company’s commitment to expanding its leadership bench and deepening its service capabilities. Central to the rollout is the appointment of Mike Guttman as Vice President of Senior Partnerships, a role that places him at the forefront of cultivating strategic relationships with the firm’s most important clients.
Guttman arrives with a robust background in client partnership and business development. Prior to joining Testronic, he spent several years at Keywords Studios, where he was responsible for nurturing large‑scale client accounts and driving revenue growth. His earlier experience also includes a senior business development manager position, where he honed his skills in negotiating complex deals and aligning service offerings with the evolving needs of game developers and publishers.
In his new capacity, Guttman will oversee the senior partnership function, ensuring that Testronic’s most valuable customers receive a tailored, results‑oriented experience that reflects the company’s Player‑Focused, Partner‑First philosophy. 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 additional support to partners both regionally and globally. She brings a wealth of experience from her time at Keywords Studios, where she served as an enterprise account executive, and from Unity, where she acted as senior account executive for the Parsec and SyncSketch products.
Her expertise in managing enterprise‑level accounts and her deep understanding of the interactive entertainment ecosystem will be instrumental in expanding Testronic’s market reach and strengthening existing relationships. In the company’s European hub, Warsaw, Testronic has appointed Mateusz Kałuża as QA Director. Kałuża’s career has been built on senior testing roles at Lionbridge Games, where he gained a reputation for delivering rigorous quality assurance services and for fostering close collaboration between testing teams and development studios.
Speaking about his new position, Kałuża emphasized the strategic importance of Warsaw as a centre of QA excellence: "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." His leadership is expected to integrate Warsaw’s talent pool with Testronic’s broader network, creating a seamless service offering that can adapt to the fast‑paced demands of modern game development. Adding to the senior leadership roster, Lily Guerreiro has been named Global Partnerships Senior Manager. Guerreiro previously held the position of Global Business Development Manager at Keywords Studios, where she was responsible for scaling partnership initiatives across multiple continents.
Her appointment signals Testronic’s intention to deepen its global partnership strategy, leveraging her experience to identify new market opportunities and to cultivate long‑term collaborations with leading studios and technology providers. The Manila Centre of Excellence has also seen significant reinforcement. Daniel Bowie Soriano joins as Senior QA Manager, bringing a track record of overseeing large‑scale testing projects and implementing best‑practice QA methodologies.
Working alongside him is Ivan Balanay, who takes on the role of QA Trainer. Balanay’s appointment is described by the company as a move that "further supports [its] investment in developing the Testronic Academy and building the next generation of QA expertise." The Academy aims to provide continuous learning pathways for QA professionals, ensuring that the Manila team remains at the cutting edge of testing techniques, automation tools, and industry standards. Chief Revenue Officer Michael Fitzgerald highlighted 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.
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 comments reflect a broader corporate vision that blends geographic diversification with deep domain expertise, allowing Testronic to offer localized support while maintaining a unified global service model. The leadership reshuffle follows a recent change at the very top of the organization.
Earlier this month, Sonia Kerr was appointed Chief Executive Officer, succeeding Sharon Baylay‑Bell, who transitioned to the role of company chair. This change marks a new chapter for Testronic, positioning Kerr to steer the company through a period of rapid growth and industry transformation. Alongside Kerr’s appointment, Michael Fitzgerald was confirmed as CRO, and Samantha Williams took on the role of Chief Commercial Officer. Fitzgerald’s prior experience as a client partner at Keywords Studios and Williams’s background as Testronic’s global CRO and head of Europe further reinforce the depth of experience now embedded within the executive team.
Collectively, these senior appointments signal Testronic’s strategic emphasis on building a robust, globally integrated leadership structure. By bringing together seasoned professionals from leading industry players, the company aims to enhance its service delivery, expand its market footprint, and continue to provide high‑quality quality assurance and localization solutions to game developers worldwide.
The expanded leadership team is expected to drive innovation, foster stronger partner relationships, and ensure that Testronic remains a trusted ally in the ever‑evolving landscape of interactive entertainment.
