Testronic has announced a series of high‑level appointments across its worldwide operations, underscoring the company’s commitment to bolstering its leadership bench and expanding its service capabilities. The most prominent addition is Mike Guttman, who has been named Vice President of Senior Partnerships. In this role, Guttman will oversee the cultivation of strategic relationships with key clients and help drive growth across Testronic’s diverse portfolio of testing and quality assurance services.
Guttman arrives at Testronic with a robust background in the interactive entertainment and outsourcing sectors. Prior to joining the firm, he spent several years as a client partner at Keywords Studios, where he was responsible for managing large‑scale accounts and delivering tailored solutions to some of the world’s leading game developers. Before that, he held the position of Senior Business Development Manager, a role that gave him deep insight into market dynamics, partnership negotiation, and revenue generation.
His track record of building long‑term client relationships and his strategic mindset make him an ideal fit for steering Testronic’s senior partnership initiatives. Supporting Guttman’s efforts is Nicole Closson, who has been appointed 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 previous tenure at Keywords Studios, where she excelled as an Enterprise Account Executive, and from her time at Unity, where she served as Senior Account Executive for the Parsec and SyncSketch product lines. Her expertise in enterprise sales and her familiarity with the gaming technology ecosystem will be instrumental in extending Testronic’s reach and deepening its engagement with existing and prospective clients.
In the European hub of Warsaw, Testronic has promoted Mateusz Kałuża to the position of QA Director. Kałuża’s career has been rooted in quality assurance, having held senior testing roles at Lionbridge Games before his current appointment.
He emphasized the strategic importance of the Warsaw office, noting that the city “brings together deep QA expertise, experience and a real understanding of what developers need from a testing partner.” Kałuża highlighted that continued investment in the local team will allow Testronic to fuse regional talent with its global capabilities, ensuring consistent, high‑quality delivery for partners regardless of their location. Another key addition to the leadership roster is Lily Guerreiro, who joins as Global Partnerships Senior Manager. Guerreiro previously served as Global Business Development Manager at Keywords Studios, where she was responsible for forging cross‑border alliances and expanding the company’s footprint in new markets.
Her global perspective and proven ability to manage complex partnership structures will be valuable assets as Testronic seeks to deepen its collaborations with major studios and technology providers worldwide. The company’s Centre of Excellence in Manila has also seen senior appointments aimed at strengthening its testing and training functions. Daniel Bowie Soriano has been brought on as Senior QA Manager, where he will oversee the execution of quality assurance projects and mentor junior staff. Alongside him, Ivan Balanay has taken on the role of QA Trainer, a position that aligns with Testronic’s broader ambition to develop the next generation of QA professionals through its Testronic Academy.
The firm highlighted that Balanay’s appointment “further supports our investment in developing the Testronic Academy and building the next generation of QA expertise.” Chief Revenue Officer Michael Fitzgerald commented on the overall strategy, stating, “Our Centres of Excellence bring together talented people, specialist expertise and leadership, and connect those capabilities across a genuinely global organisation.” He went on to explain that the recent investments in New Orleans, Warsaw, and Manila—complemented by an established presence in London—serve to “further strengthen the expertise available to our partners.” Fitzgerald emphasized that by continuing to invest in outstanding talent, Testronic 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, succeeding Sharon Baylay‑Bell, who transitioned to the role of company chair.
In addition, Michael Fitzgerald was confirmed as Chief Revenue Officer, while Samantha Williams took on the position 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 Europe, bringing a deep understanding of both the commercial and operational dimensions of the business.
Overall, Testronic’s strategic hiring and promotion agenda reflects a deliberate effort to align its leadership talent with the evolving needs of the gaming and interactive media industry. By reinforcing its senior ranks with individuals who possess extensive experience in client partnership, business development, and quality assurance, the company aims to enhance its service delivery, expand its market presence, and maintain a competitive edge in a rapidly changing landscape.
The combination of seasoned executives, regional expertise, and a commitment to continuous investment in people positions Testronic to meet the growing expectations of developers and publishers seeking reliable, player‑centric testing solutions.
