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 announcement is the elevation of Mike Guttman to the role of Vice President of Senior Partnerships, a position that will see him spearheading strategic relationships with the firm’s most important clients. Guttman arrives at Testronic with a robust background in the interactive entertainment services sector. He previously held the title of client partner at Keywords Studios, where he was responsible for nurturing large‑scale accounts and driving growth across multiple regions.
Prior to that, he worked as a senior business development manager, honing his ability to identify market opportunities and translate them into concrete revenue streams. At Testronic, Guttman will leverage this experience to deepen existing collaborations and forge new alliances that align with the company’s player‑focused, partner‑first philosophy.
Supporting Guttman’s efforts is Nicole Closson, who joins the team as Business Development Manager. Closson’s mandate is to broaden commercial coverage and provide additional support to partners both locally and globally.
Her career trajectory includes a stint as an enterprise account executive at Keywords Studios, where she managed high‑value client portfolios, and a senior account executive role at Unity, overseeing accounts for Parsec and SyncSketch. Together, Guttman and Closson are expected to enhance Testronic’s market reach and deliver a more integrated service offering. In the European hub of Warsaw, Testronic has appointed Mateusz Kałuża as QA Director. Kałuża brings a wealth of experience from his previous senior testing positions at Lionbridge Games, where he led quality assurance initiatives for numerous high‑profile titles.
Speaking about his new role, Kałuża highlighted Warsaw’s reputation as a centre of QA excellence, noting that the city combines deep technical expertise with a nuanced understanding of developers’ needs from a testing partner. He emphasized that continued investment in the local team will allow Testronic to fuse regional talent with its broader global capabilities, ensuring consistent delivery for partners regardless of geographic location. Adding to the leadership roster, Lily Guerreiro steps in as Global Partnerships Senior Manager. Guerreiro’s background includes serving as Global Business Development Manager at Keywords Studios, where she was instrumental in expanding the company’s international footprint.
Her appointment signals Testronic’s intent to strengthen cross‑border collaboration and streamline partnership processes on a worldwide scale. The Manila Centre of Excellence also sees new senior talent.
Daniel Bowie Soriano has been named Senior QA Manager, tasked with overseeing quality assurance operations and driving process improvements within the hub. Complementing Soriano’s role is Ivan Balanay, who joins as QA Trainer.
Balanay’s addition is part of Testronic’s broader strategy to invest in the Testronic Academy, a training initiative aimed at cultivating the next generation of QA professionals. The company’s Chief Revenue Officer, Michael Fitzgerald, highlighted that these appointments reinforce the Academy’s mission to build deep, sustainable expertise in the region. Fitzgerald, who also serves as the firm’s Chief Revenue Officer, articulated the strategic importance of these moves: "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." These leadership changes come on the heels of a broader executive reshuffle earlier in the month. Sonia Kerr was appointed Chief Executive Officer, taking the reins from Sharon Baylay‑Bell, who transitioned to the role of company chair. In addition, Michael Fitzgerald was confirmed as Chief Revenue Officer, while Samantha Williams stepped into the position of Chief Commercial Officer.
Fitzgerald’s background includes a client partner role at Keywords Studios, and Williams previously served as Testronic’s global CRO and head of Europe, bringing extensive commercial and operational experience to her new post. Collectively, the new appointments reflect Testronic’s strategic emphasis on scaling its leadership talent pool to meet growing client demands. By integrating seasoned professionals from leading industry players such as Keywords Studios and Unity, the company aims to enhance its service portfolio, accelerate innovation, and maintain a high standard of quality across all its Centres of Excellence. The expanded senior team is poised to drive forward Testronic’s mission of delivering reliable, player‑centric testing solutions while fostering strong, collaborative partnerships worldwide.
