Testronic has undertaken a sweeping series of senior‑level appointments across its worldwide operations, signaling a strategic push to deepen its leadership bench and broaden its service capabilities. At the forefront of this expansion is the promotion of Mike Guttman to the role of Vice President of Senior Partnerships. Guttman's new position places him at the helm of cultivating and managing high‑value relationships with Testronic’s most strategic clients, ensuring that the company’s partnership model remains both proactive and results‑driven.
Before joining Testronic, Guttman amassed extensive experience in the interactive entertainment services sector. He previously held the title of client partner at Keywords Studios, where he was responsible for overseeing a portfolio of major publishing accounts and driving revenue growth through tailored service offerings.
In addition, he served as a senior business development manager, a role that sharpened his ability to identify market opportunities, negotiate complex contracts, and align service delivery with client expectations. His track record of delivering measurable outcomes makes him a natural fit for steering Testronic’s senior partnership initiatives. Supporting Guttman in the expansion of commercial coverage is Nicole Closson, who steps into the role of Business Development Manager. Closson’s mandate is to broaden Testronic’s reach both regionally and globally, providing additional bandwidth for partner support and ensuring that the company’s sales engine remains robust.
Her background includes a tenure as an enterprise account executive at Keywords Studios, where she managed large‑scale accounts and cultivated long‑term client relationships. She also spent time at Unity, serving as a senior account executive for the Parsec and SyncSketch product lines, where she gained deep insight into the needs of developers using real‑time collaboration tools. Together, Guttman and Closson are expected to reinforce Testronic’s market presence and deliver a seamless experience for partners across multiple continents.
In Europe, the Warsaw office has welcomed a new leader in quality assurance: Mateusz Kałuża, who has been appointed QA Director. Kałuża arrives with a solid foundation in testing, having previously occupied senior testing positions at Lionbridge Games. He emphasizes that Warsaw serves as a hub of sophisticated QA talent, offering a nuanced understanding of what developers require from a testing partner.
"Warsaw brings together deep QA expertise, experience and a real understanding of what developers need from a testing partner," Kałuża explained. "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 underscores Testronic’s commitment to leveraging regional strengths while integrating them into a cohesive global service model.
Further bolstering the company’s partnership function is Lily Guerreiro, who joins as Global Partnerships Senior Manager. Guerreiro’s prior experience includes a role as Global Business Development Manager at Keywords Studios, where she honed her skills in scaling partnership programs across multiple markets.
In her new capacity, she will focus on aligning global partnership strategies with the company’s overarching objectives, ensuring consistency and excellence in partner interactions worldwide. The Manila Centre of Excellence has also seen senior leadership additions. Daniel Bowie Soriano steps into the role of Senior QA Manager, bringing a wealth of hands‑on testing expertise and a proven ability to lead cross‑functional QA teams.
Working alongside him is Ivan Balanay, appointed as QA Trainer. Balanay’s role is pivotal to Testronic’s investment in the Testronic Academy, an internal training initiative designed to cultivate the next generation of QA professionals.
"Ivan's appointment further supports our investment in developing the Testronic Academy and building the next generation of QA expertise," the company noted, highlighting its focus on talent development and continuous learning. Chief Revenue Officer Michael Fitzgerald articulated the strategic rationale behind these appointments, stating, "Our Centres of Excellence bring together talented people, specialist expertise and leadership, and connect those capabilities across a genuinely global organisation." He further emphasized the significance of geographic diversification: "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 named Chief Executive Officer, succeeding Sharon Baylay‑Bell, who transitioned to the role of company chair.
In addition, Michael Fitzgerald was confirmed as CRO, while Samantha Williams assumed the position of Chief Commercial Officer. Fitzgerald brings experience as a client partner from Keywords Studios, and Williams previously served as Testronic’s global CRO and head of Europe, equipping her with a comprehensive view of the company’s commercial landscape.
Collectively, these appointments reflect Testronic’s deliberate strategy to reinforce its leadership pipeline, deepen regional expertise, and enhance its ability to serve a global client base with consistency and high quality. By aligning senior talent with its Centres of Excellence in New Orleans, Warsaw, Manila, and London, Testronic aims to deliver a seamless, player‑centric experience that prioritizes partner success and measurable outcomes across the gaming and interactive entertainment industry.
