Testronic has undertaken a broad series of senior‑level appointments across its worldwide operations, underscoring the company’s commitment to scaling both its leadership depth and its service capabilities. Central to this wave of changes is the appointment of Mike Guttman as Vice President of Senior Partnerships, a role that places him at the helm of the firm’s most strategic alliance initiatives. Guttman arrives at Testronic with a robust background in client‑facing and business‑development roles.
Prior to joining, he spent several years as a client partner at Keywords Studios, where he was responsible for nurturing high‑value relationships and driving growth across multiple market segments. He also held the position of senior business development manager, gaining hands‑on experience in identifying new revenue streams, negotiating complex contracts, and aligning service offerings with client objectives. This blend of partnership stewardship and commercial acumen makes him well‑suited to lead Testronic’s senior partnership program, which aims to deepen existing collaborations while forging new, mutually beneficial relationships. Complementing Guttman’s appointment, Nicole Closson has been brought on board as Business Development Manager.
In this capacity, Closson will expand commercial coverage and provide dedicated support to partners both regionally and on a global scale. Her prior experience includes a stint as an enterprise account executive at Keywords Studios, where she managed large‑scale accounts and delivered tailored solutions to meet diverse client needs. She also served as a senior account executive for Parsec and SyncSketch at Unity, further sharpening her ability to translate technical product knowledge into compelling business value propositions. Together, Guttman and Closson are expected to create a synergistic leadership duo that will enhance Testronic’s market reach and deepen partner trust.
In Europe, the Warsaw office has seen a notable leadership shift with the promotion of Mateusz Kałuża to QA Director. Kałuża’s career trajectory includes senior testing positions at Lionbridge Games, where he honed his expertise in quality assurance processes for interactive entertainment titles.
Speaking about his new role, Kałuża highlighted Warsaw’s strategic importance: "The city brings together deep QA expertise, experience, and a genuine understanding of what developers require 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 appointment signals Testronic’s intention to leverage Warsaw’s talent pool as a hub for high‑quality testing services, while also integrating those capabilities with the company’s broader global network. Further strengthening the global partnership function, Lily Guerreiro joins as Global Partnerships Senior Manager.
Guerreiro’s background includes serving as Global Business Development Manager at Keywords Studios, where she oversaw cross‑border partnership initiatives and cultivated relationships with major industry players. Her experience in navigating complex, multi‑regional deals will be instrumental as Testronic seeks to standardize its partnership approach across continents.
The Manila Centre of Excellence, a critical pillar of Testronic’s service delivery model, also welcomed senior talent. Daniel Bowie Soriano steps into the role of Senior QA Manager, bringing a wealth of experience in overseeing large‑scale testing operations and driving process improvements.
Alongside him, Ivan Balanay has been appointed QA Trainer, a position that directly supports the company’s investment in the Testronic Academy—a training platform designed to develop the next generation of QA specialists. The firm emphasized that Balanay’s addition “further supports our investment in developing the Testronic Academy and building the next generation of QA expertise,” underscoring the strategic focus on talent development and knowledge transfer. Chief Revenue Officer Michael Fitzgerald summed up the strategic rationale behind 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." This comment reflects a broader corporate philosophy that places people and partnership outcomes at the core of Testronic’s growth agenda.
These leadership changes come on the heels of a significant executive reshuffle earlier in the 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 announced as Chief Revenue Officer, while Samantha Williams took on the mantle of Chief Commercial Officer. Fitzgerald’s prior experience as a client partner at Keywords Studios and Williams’s tenure as Testronic’s global CRO and head of Europe further reinforce the company’s strategy of drawing talent from established industry leaders to drive its next phase of expansion.
Overall, Testronic’s series of senior appointments across its global footprint—spanning North America, Europe, and Asia—demonstrates a deliberate effort to align leadership talent with regional market dynamics and service excellence. By bolstering its executive bench with seasoned professionals who possess deep domain knowledge and proven partnership‑building skills, the company is positioning itself to meet the evolving demands of game developers, publishers, and interactive media creators worldwide. The combined expertise of these new leaders is expected to accelerate Testronic’s mission to deliver high‑quality, player‑centric testing solutions while maintaining a partner‑first ethos that drives long‑term success for both the firm and its clients.
