Testronic has announced a series of high‑level appointments across its worldwide operations, signaling a strategic push to deepen its service capabilities and broaden its market reach. Central to this wave of leadership changes is the elevation of Mike Guttman to the role of Vice President of Senior Partnerships.
In this capacity, Guttman will be responsible for nurturing and expanding relationships with the company’s most significant clients, leveraging his extensive background in business development and client partnership management. Before joining Testronic, Guttman built a solid reputation at Keywords Studios, where he served as a client partner, and earlier he held a senior business development manager position.
His experience spans negotiating complex contracts, aligning service delivery with client objectives, and driving revenue growth in the interactive entertainment sector. At Testronic, he will apply these skills to strengthen the firm’s senior‑level collaborations and to spearhead new initiatives that align with the company’s player‑focused, partner‑first philosophy. Complementing Guttman’s appointment is the addition of Nicole Closson as Business Development Manager. Closson’s mandate is to broaden commercial coverage and provide dedicated support to partners both regionally and globally.
She brings a rich portfolio of experience, having previously worked at Keywords Studios as an enterprise account executive, where she managed large‑scale accounts, and at Unity, where she served as a senior account executive for the Parsec and SyncSketch products. Her deep understanding of the gaming and technology ecosystems equips her to identify growth opportunities and to craft tailored solutions for Testronic’s diverse clientele.
In the European hub of Warsaw, the company has promoted Mateusz Kałuża to the position of QA Director. Kałuża arrives with a robust background in quality assurance, having held senior testing roles at Lionbridge Games.
He highlighted the strategic importance of Warsaw, stating, "The city combines deep QA expertise, extensive experience, and a genuine grasp of what developers require from a testing partner. Our ongoing investment in the team will nurture this expertise locally, integrate it fully with Testronic’s global capabilities, and ensure consistent delivery for partners wherever they operate." Under his leadership, the Warsaw office is expected to serve as a critical node for delivering high‑quality testing services across Europe and beyond.
Further reinforcing the company’s global partnership strategy, Lily Guerreiro has been appointed Global Partnerships Senior Manager. Guerreiro’s prior role as Global Business Development Manager at Keywords Studios gave her a panoramic view of international client needs and the ability to coordinate cross‑border initiatives. In her new capacity, she will oversee the coordination of partnership activities across multiple regions, ensuring alignment with Testronic’s broader strategic objectives. The Manila Centre of Excellence, a cornerstone of Testronic’s operational model, also welcomed senior talent.
Daniel Bowie Soriano has joined as Senior QA Manager, bringing a wealth of experience in quality assurance leadership. Alongside him, Ivan Balanay has taken on the role of QA Trainer, a position that underscores the company’s commitment to cultivating the next generation of QA professionals.
Balanay’s appointment was described as a reinforcement of the investment in the Testronic Academy, an internal training program designed to elevate technical skills and industry knowledge among staff. Michael Fitzgerald, the company’s Chief Revenue Officer, emphasized the strategic importance 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." He further elaborated on the geographic diversification of the firm’s talent pool, stating, "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 appointed Chief Executive Officer, taking over from 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’s background includes a tenure as a client partner at Keywords Studios, while Williams previously served as Testronic’s global CRO and head of Europe, bringing a deep understanding of both commercial strategy and regional market dynamics. Collectively, these appointments reflect Testronic’s deliberate strategy to enhance its leadership depth, broaden its geographic footprint, and reinforce its commitment to delivering high‑quality testing and localization services.
By integrating seasoned professionals with proven track records in client partnership, business development, and quality assurance, the company aims to provide a seamless, end‑to‑end experience for game developers and publishers worldwide. The expanded senior team is expected to drive innovation, improve service delivery, and solidify Testronic’s position as a trusted partner in the highly competitive gaming industry.
