Testronic has recently undertaken a significant reshuffle of its senior leadership across a number of its worldwide offices, underscoring the company’s commitment to deepening its service capabilities and expanding its market reach. Among the most notable appointments is that of Mike Guttman, who has been promoted to the role of Vice President of Senior Partnerships. In this capacity, Guttman will be responsible for overseeing high‑level collaborations with key clients, steering strategic initiatives, and ensuring that Testronic’s partnership model continues to deliver measurable value.
Guttman arrives at Testronic with a solid background in the interactive entertainment sector. Prior to joining the firm, he held the position of client partner at Keywords Studios, where he managed a portfolio of large‑scale accounts and helped shape the studio’s business development strategy. He also previously served as a senior business development manager, gaining experience in negotiating complex contracts and fostering long‑term relationships with major publishers and developers.
This blend of client‑facing expertise and strategic insight makes him well‑suited to guide Testronic’s senior partnership agenda. Supporting Guttman’s efforts is Nicole Closson, who has been brought on board as 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 tenure at Keywords Studios, where she worked as an enterprise account executive, as well as from Unity, where she acted as senior account executive for the Parsec and SyncSketch products. Her deep understanding of enterprise‑level sales cycles and her proven track record in cultivating high‑value relationships will complement Guttman’s strategic vision. In the European hub of Warsaw, Testronic has named Mateusz Kałuża as its new QA Director.
Kałuża joins the company after a series of senior testing roles at Lionbridge Games, where he honed his expertise in quality assurance processes for interactive media. Speaking about his new role, Kałuża highlighted Warsaw’s reputation as a center of QA excellence, noting that the city combines a strong technical talent pool with a nuanced appreciation of developers’ needs from a testing partner.
He emphasized that Testronic’s ongoing investment in the local team will not only enhance regional expertise but also integrate that knowledge seamlessly with the firm’s broader global capabilities, ensuring consistent delivery standards for partners worldwide. Further strengthening the global partnership function is Lily Guerreiro, who steps into the position of Global Partnerships Senior Manager.
Guerreiro previously served as Global Business Development Manager at Keywords Studios, where she led cross‑border initiatives and helped expand the company’s footprint in emerging markets. Her experience in orchestrating large‑scale partnership programs will be instrumental in aligning Testronic’s global strategy with the specific demands of diverse client bases. The Manila Centre of Excellence has also seen senior leadership upgrades. Daniel Bowie Soriano has been appointed Senior QA Manager, bringing a hands‑on approach to overseeing testing operations and mentoring junior staff.
Alongside him, Ivan Balanay takes on the role of QA Trainer, a position that directly supports Testronic’s investment in the Testronic Academy—a training platform designed to cultivate the next generation of QA professionals. Balanay’s appointment is described by the company as a key element in strengthening the Academy’s curriculum and ensuring that trainees acquire the practical skills required to meet industry standards. Chief Revenue Officer Michael Fitzgerald commented on 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 strategic investments being made in locations such as New Orleans, Warsaw, and Manila, together with the established presence in London, are intended to broaden the depth and breadth of expertise available to Testronic’s partners. By continuing to attract and develop outstanding talent, the firm aims to deliver a service model that is player‑focused, partner‑first, and outcomes‑led.
These leadership changes come on the heels of a broader 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. In addition, Michael Fitzgerald was confirmed as CRO, while Samantha Williams took on the role of Chief Commercial Officer.
Fitzgerald’s background includes a stint as a client partner at Keywords Studios, whereas Williams previously served as Testronic’s global CRO and head of Europe, bringing extensive commercial experience to her new portfolio. Overall, the series of senior appointments reflects Testronic’s strategic emphasis on building a robust, globally integrated leadership team capable of driving growth, enhancing service quality, and fostering deeper collaborations with partners across the video game and interactive entertainment ecosystem. By aligning seasoned professionals with key regional hubs, the company positions itself to meet evolving industry demands, support innovative development cycles, and maintain a competitive edge in the rapidly changing landscape of quality assurance and player experience testing.
