Testronic has announced a series of high‑level appointments across its worldwide operations, underscoring the company’s commitment to strengthening its leadership and service capabilities. Among the most notable additions is Mike Guttman, who has been named Vice President of Senior Partnerships. Guttman arrives with a robust background in client relations and business development, having previously held the role of client partner at Keywords Studios and served as a senior business development manager in the interactive entertainment sector. In his new capacity, Guttman will be responsible for cultivating and expanding strategic relationships with Testronic’s most important partners, ensuring that the company’s service offerings remain aligned with the evolving needs of game developers and publishers.
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 regionally and globally.
She brings valuable experience from her tenure at Keywords Studios, where she worked as an enterprise account executive, and from Unity, where she held senior account executive positions for products such as Parsec and SyncSketch. Her deep understanding of enterprise sales cycles and her proven track record of managing large‑scale accounts will be instrumental in driving revenue growth and enhancing client satisfaction. In the European hub of Warsaw, Testronic has elevated Mateusz Kałuża to the role of QA Director.
Kałuża’s promotion follows a distinguished career in quality assurance, most recently as a senior tester at Lionbridge Games. He emphasized the strategic importance of the Warsaw office, stating, "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." Under his leadership, the Warsaw team will focus on integrating local talent with the broader Testronic network, delivering seamless testing solutions that meet the high standards expected by the industry. Further strengthening the company’s global partnership function, Lily Guerreiro has been appointed Global Partnerships Senior Manager. Guerreiro previously served as Global Business Development Manager at Keywords Studios, where she honed her skills in forging cross‑border collaborations and scaling business initiatives across multiple markets.
In her new role, she will oversee the coordination of partnership strategies on a worldwide scale, ensuring that Testronic’s services are consistently delivered with a player‑focused, partner‑first mindset. The Manila Centre of Excellence, a critical node in Testronic’s service delivery model, also received senior leadership upgrades. Daniel Bowie Soriano joins as Senior QA Manager, bringing extensive experience in quality assurance leadership and process optimization.
Working alongside him is Ivan Balanay, who takes on the position of QA Trainer. Balanay’s appointment is part of Testronic’s broader investment in the Testronic Academy, an internal training program designed to cultivate the next generation of QA professionals. The company highlighted that Balanay’s role will "further support our investment in developing the Testronic Academy and building the next generation of QA expertise," reinforcing the firm’s dedication to continuous learning and talent development.
Chief Revenue Officer Michael Fitzgerald commented on the strategic significance of these appointments, noting, "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 Testronic’s holistic approach: combining geographic expansion with deepening expertise to create a resilient, client‑centric service model. 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, and Samantha Williams was named Chief Commercial Officer. Fitzgerald previously served as a client partner at Keywords Studios, while Williams held the position of global CRO and head of Europe at Testronic, bringing internal continuity and industry insight to the senior management team.
Overall, Testronic’s series of senior appointments reflects a deliberate strategy to enhance its global footprint, deepen technical expertise, and reinforce its commitment to delivering high‑quality testing services. By positioning seasoned professionals in key markets such as New Orleans, Warsaw, Manila, and London, the company aims to provide a seamless, end‑to‑end experience for developers seeking reliable, player‑centric quality assurance solutions. The expanded leadership team is expected to drive further growth, foster innovation in testing methodologies, and maintain Testronic’s reputation as a trusted partner in the fast‑evolving gaming industry.
