Testronic has announced a series of high‑level appointments across its worldwide operations, underscoring the company’s commitment to expanding its leadership bench and strengthening its service offering. Central to the announcement is the elevation of Mike Guttman to the role of Vice President of Senior Partnerships.
In this capacity, Guttman will be responsible for overseeing strategic relationships with key clients, driving growth initiatives, and ensuring that Testronic’s partnership model remains aligned with the evolving needs of the gaming and interactive entertainment industry. Before joining Testronic, Guttman built a solid reputation at Keywords Studios, where he worked as a client partner, cultivating long‑term accounts and delivering tailored solutions to a diverse portfolio of developers. He also held the position of senior business development manager, where he honed his skills in market analysis, deal structuring, and cross‑functional collaboration.
His blend of client‑facing experience and strategic insight makes him a natural fit for steering Testronic’s senior partnership agenda. Supporting Guttman in expanding the company’s commercial reach is Nicole Closson, who steps into the role of Business Development Manager. Closson’s mandate is to broaden Testronic’s market coverage and provide dedicated support to partners both regionally and globally.
Her background includes a stint as an enterprise account executive at Keywords Studios, where she managed large‑scale contracts and drove revenue growth. She also spent time at Unity, serving as senior account executive for the Parsec and SyncSketch products, gaining valuable exposure to cutting‑edge collaboration tools used by developers worldwide. Together, Guttman and Closson form a leadership duo aimed at deepening client engagement and delivering more nuanced, value‑added services.
In the company’s European hub, Warsaw, Testronic has appointed Mateusz Kałuża as QA Director. Kałuża arrives with a wealth of experience from senior testing positions at Lionbridge Games, where he oversaw quality assurance pipelines for numerous high‑profile titles. Speaking about his new role, Kałuża highlighted Warsaw’s unique position as a centre of QA excellence: "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." His appointment signals a strategic push to integrate local talent with the broader Testronic network, ensuring that clients receive consistent, high‑quality testing services regardless of geography. Further reinforcing the global partnership team, Lily Guerreiro joins as Global Partnerships Senior Manager. Guerreiro previously held the title of Global Business Development Manager at Keywords Studios, where she was instrumental in expanding the firm’s international client base and forging strategic alliances across multiple continents.
Her expertise in navigating cross‑border negotiations and her deep understanding of the gaming market will be pivotal as Testronic seeks to scale its partnership model. The Manila Centre of Excellence, a critical node in Testronic’s operational map, also sees two senior appointments. Daniel Bowie Soriano steps into the role of Senior QA Manager, bringing a robust background in quality assurance leadership and a track record of implementing rigorous testing standards. Alongside him, Ivan Balanay has been named QA Trainer, tasked with developing the next generation of testing professionals through the Testronic Academy.
The company emphasized that Balanay’s addition "further supports our investment in developing the Testronic Academy and building the next generation of QA expertise," reinforcing the firm’s dedication to talent development and continuous learning. Chief Revenue Officer Michael Fitzgerald commented on the broader significance 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." Fitzgerald’s remarks underscore the strategic intent behind the geographic diversification of talent and the emphasis on a partner‑centric service model.
These leadership changes come on the heels of a major executive reshuffle earlier in the month, when Testronic appointed Sonia Kerr as Chief Executive Officer, succeeding Sharon Baylay‑Bell, who transitioned to the role of company chair. In the same announcement, Michael Fitzgerald was confirmed as CRO, while Samantha Williams took on the position of Chief Commercial Officer. Fitzgerald’s prior experience includes a client‑partner role at Keywords Studios, and Williams previously served as Testronic’s global CRO and head of Europe, bringing deep operational insight to her new responsibilities.
Collectively, these appointments reflect Testronic’s strategic focus on scaling its leadership talent pool, deepening regional expertise, and reinforcing its commitment to delivering high‑quality QA and partnership services worldwide. By aligning seasoned professionals with key market hubs—New Orleans, Warsaw, Manila, and London—the company aims to provide a seamless, globally coordinated experience for developers seeking reliable testing solutions.
The expanded senior team is expected to drive innovation, foster stronger client relationships, and sustain Testronic’s reputation as a trusted partner in the fast‑moving world of interactive entertainment.
