Testronic has announced a series of high‑level appointments across its worldwide operations, underscoring the company’s commitment to expanding its leadership bench and enhancing service delivery for game developers and interactive media partners. Among the most notable additions is Mike Guttman, who has been named Vice President of Senior Partnerships. In this capacity, Guttman will oversee the cultivation of strategic relationships with key accounts, ensuring that Testronic’s testing and quality‑assurance solutions align closely with the evolving needs of its clients.
Guttman arrives with a solid background in the entertainment services sector. Prior to joining Testronic, he held the role of client partner at Keywords Studios, where he was responsible for managing large‑scale client portfolios and driving revenue growth through tailored service offerings. He also spent several years as a senior business development manager, honing his ability to identify market opportunities, negotiate complex contracts, and foster long‑term partnerships. His experience in both client‑facing and business‑development functions positions him well to lead Testronic’s senior partnership initiatives on a global scale.
Supporting Guttman’s mandate is Nicole Closson, who steps into the role of Business Development Manager. Closson’s appointment is intended to broaden Testronic’s commercial reach and provide additional support to partners both regionally and worldwide. She brings a wealth of experience from her previous tenure at Keywords Studios, where she served as an enterprise account executive, managing high‑value accounts and delivering customized solutions.
Before that, she worked at Unity, acting as a senior account executive for the Parsec and SyncSketch products, where she gained deep insight into real‑time collaboration tools and cloud‑based workflows. Together, Guttman and Closson will aim to strengthen Testronic’s market presence and deepen relationships with existing and prospective clients. In the European hub of Warsaw, Testronic has promoted Mateusz Kałuża to the position of QA Director. Kałuża’s promotion follows a distinguished career in quality assurance, most recently as a senior testing lead at Lionbridge Games.
He highlighted the strategic importance of Warsaw in a statement: "Warsaw brings together deep QA expertise, experience and a real understanding of what developers need 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." By anchoring a senior QA leadership role in Warsaw, Testronic aims to leverage the city’s strong technical talent pool and its proximity to a vibrant game development ecosystem.
Further bolstering the global partnership function, Lily Guerreiro has been appointed Global Partnerships Senior Manager. Guerreiro previously held the title of Global Business Development Manager at Keywords Studios, where she was responsible for expanding the firm’s international client base and orchestrating cross‑border service delivery. Her expertise in navigating multi‑regional business environments will be instrumental as Testronic seeks to harmonize its partnership strategies across continents. The Manila Centre of Excellence, a critical node in Testronic’s service network, also received senior leadership upgrades.
Daniel Bowie Soriano joins the team as Senior QA Manager, bringing a track record of leading large‑scale testing projects and mentoring junior QA staff. Alongside him, Ivan Balanay has been appointed QA Trainer, a role that directly supports the company’s investment in the Testronic Academy—a training initiative designed to cultivate the next generation of QA specialists.
The organization emphasized that Balanay’s addition "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 broader strategic picture: "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 highlight the company’s multi‑city approach, which is designed to provide clients with localized expertise while maintaining a cohesive, global service framework. In recent months, Testronic has also undergone a leadership transition at the very top.
Earlier this month, Sonia Kerr was appointed Chief Executive Officer, succeeding Sharon Baylay‑Bell, who transitioned to the role of company chair. This change marks a new chapter for the firm, with Kerr expected to steer Testronic through continued growth and diversification of its service portfolio. Alongside Kerr’s appointment, Michael Fitzgerald was formally announced as Chief Revenue Officer, while Samantha Williams took on the role of Chief Commercial Officer.
Fitzgerald’s background includes a stint as a client partner at Keywords Studios, where he cultivated deep relationships with major publishers and developers. Williams, meanwhile, previously served as Testronic’s global CRO and head of Europe, bringing a comprehensive understanding of the company’s commercial operations and market dynamics. Collectively, these appointments signal Testronic’s strategic emphasis on strengthening its leadership talent across key geographic locations and functional areas.
By integrating seasoned professionals from both within and outside the organization, Testronic aims to enhance its service quality, accelerate innovation in testing methodologies, and provide a more responsive, partner‑centric experience for its global client base. The expanded leadership team is expected to drive forward the company’s vision of delivering high‑quality, player‑focused outcomes that support developers throughout the entire lifecycle of their games and interactive experiences.
