Testronic has announced a series of high‑level appointments across its worldwide operations, underscoring the company’s commitment to deepening its service capabilities and expanding its leadership bench. Central to the announcement is the elevation of Mike Guttman to the role of Vice President of Senior Partnerships, a position that places him at the forefront of cultivating and managing the firm’s most strategic relationships.
Guttman arrives with a robust background in client‑facing roles within the interactive entertainment sector. Prior to joining Testronic, he held the title of client partner at Keywords Studios, where he was responsible for overseeing a portfolio of major accounts and driving growth through tailored service offerings. He also spent time as a senior business development manager, honing his ability to identify market opportunities, negotiate complex contracts, and align service delivery with client objectives. His blend of strategic insight and hands‑on experience makes him well suited to lead Testronic’s senior partnership initiatives.
Supporting Guttman in expanding the company’s commercial reach is Nicole Closson, who has been appointed Business Development Manager. Closson’s mandate is to broaden commercial coverage and provide dedicated support to partners both regionally and globally. She brings a wealth of experience from her previous roles at Keywords Studios, where she served as an enterprise account executive, and at Unity, where she worked as a senior account executive for the Parsec and SyncSketch platforms. In those capacities, she cultivated strong relationships with large‑scale developers and helped them integrate cutting‑edge tools into their production pipelines.
Her expertise in enterprise sales and account management will be instrumental in strengthening Testronic’s market position. In the European hub of Warsaw, Testronic has named Mateusz Kałuża as its new QA Director. Kałuża’s career has been rooted in quality assurance, most notably through senior testing positions at Lionbridge Games, where he led teams that delivered rigorous testing services for high‑profile gaming titles. Speaking about his new role, Kałuża highlighted Warsaw’s strategic importance: "The city combines deep QA expertise, seasoned experience, and a genuine understanding of what developers need from a testing partner.
Our ongoing investment in the local team will allow us to grow that expertise, integrate it fully with Testronic’s global capabilities, and consistently deliver value to partners wherever they are based." His appointment signals Testronic’s intention to leverage Warsaw as a central node for European QA operations, fostering closer collaboration between regional specialists and the broader corporate network. Further strengthening the company’s global partnership function, Lily Guerreiro has joined as Global Partnerships Senior Manager.
Guerreiro previously held the role of Global Business Development Manager at Keywords Studios, where she oversaw cross‑border initiatives and helped expand the firm’s footprint in emerging markets. Her experience in navigating complex international deals and her deep understanding of the gaming industry’s evolving needs position her to drive Testronic’s partnership strategy on a worldwide scale.
The Manila Centre of Excellence, a key pillar of Testronic’s service delivery model, also welcomed senior talent. Daniel Bowie Soriano has been appointed Senior QA Manager, bringing years of hands‑on testing leadership to the team. Alongside him, Ivan Balanay has taken on the role of QA Trainer, a position that directly supports the company’s investment in the Testronic Academy—a training program designed to cultivate the next generation of QA professionals.
The firm highlighted Balanay’s appointment as a critical component of its talent‑development strategy, emphasizing the importance of building a pipeline of skilled testers who can meet the increasingly sophisticated demands of modern game development. Chief Revenue Officer Michael Fitzgerald commented on the broader significance of these appointments: "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 reflect Testronic’s strategic vision of integrating regional strengths into a cohesive, client‑centric service model.
The leadership reshuffle follows a series of recent executive changes at the company. Earlier this month, Sonia Kerr was appointed Chief Executive Officer, succeeding Sharon Baylay‑Bell, who transitioned to the role of company chair. In addition, Michael Fitzgerald was officially announced as CRO, while Samantha Williams took on the responsibilities of Chief Commercial Officer. Fitzgerald’s background includes a stint as a client partner at Keywords Studios, and Williams previously served as Testronic’s global CRO and head of European operations, bringing continuity and deep institutional knowledge to the senior management team.
Collectively, these appointments signal Testronic’s aggressive push to scale its operations, deepen its expertise, and reinforce its commitment to delivering high‑quality testing and localization services. By bolstering leadership in key markets—New Orleans for North American outreach, Warsaw as a European QA hub, and Manila as an Asian centre of excellence—the company aims to provide seamless, end‑to‑end support for developers worldwide.
The strategic emphasis on talent development, through initiatives like the Testronic Academy, further ensures that the firm can meet the evolving technical and creative challenges that modern game development presents. In summary, Testronic’s expanded senior leadership team—featuring Mike Guttman, Nicole Closson, Mateusz Kałuża, Lily Guerreiro, Daniel Bowie Soriano, and Ivan Balanay—reflects a deliberate strategy to fuse regional expertise with a unified global vision. The company’s continued investment in people, processes, and geographic presence positions it to offer a player‑focused, partner‑first approach that promises consistent, high‑impact outcomes for its clients across the gaming ecosystem.
