Testronic has undertaken a series of high‑level appointments across its worldwide operations, signaling a strategic push to deepen its leadership bench and broaden its service capabilities. Among the most notable moves is the elevation of Mike Guttman to the role of Vice President of Senior Partnerships. Guttman arrives with a robust background in client relationship management, having previously held the position of client partner at Keywords Studios, where he was responsible for nurturing large‑scale accounts and driving growth across multiple market segments.
Prior to that, he served as a senior business development manager, gaining extensive experience in forging new business opportunities and steering complex negotiations. In his new capacity at Testronic, Guttman will oversee the cultivation of senior‑level alliances, ensuring that the company’s partnership framework aligns with the evolving needs of game developers, publishers, and technology providers worldwide. Supporting Guttman’s mandate is the addition of Nicole Closson, who joins the firm as Business Development Manager.
Closson’s mandate is to "further enhance commercial coverage and support partners in the region and worldwide," a statement that underscores Testronic’s ambition to expand its market reach and provide more granular support to its client base. Closson brings a wealth of experience from her tenure at Keywords Studios, where she excelled as an enterprise account executive, managing high‑value contracts and delivering tailored solutions to a diverse portfolio of customers. She also spent time at Unity, where she acted as senior account executive for the Parsec and SyncSketch products, deepening her understanding of real‑time collaboration tools and interactive media workflows.
Her combined expertise in enterprise sales and technical account management positions her well to bridge the gap between Testronic’s service offerings and the specific demands of its partners. In the European hub of Warsaw, Testronic has appointed Mateusz Kałuża as QA Director. Kałuża’s career trajectory includes senior testing roles at Lionbridge Games, where he honed his skills in quality assurance for complex, multi‑platform titles. Speaking about his new role, Kałuża noted, "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 comment highlights the strategic importance of the Warsaw centre as a nexus of technical talent and regional market insight, enabling Testronic to deliver localized support while leveraging its global network. Further strengthening the partnership function is Lily Guerreiro, who steps into the position of Global Partnerships Senior Manager. Guerreiro previously served as Global Business Development Manager at Keywords Studios, where she was instrumental in expanding the company’s footprint across multiple continents.
Her experience in orchestrating cross‑border collaborations and her deep familiarity with the gaming ecosystem will be valuable assets as Testronic seeks to standardize its partnership processes and scale its service delivery. The Manila Centre of Excellence also sees senior talent added to its ranks. Daniel Bowie Soriano has been appointed Senior QA Manager, bringing a seasoned perspective on test strategy, automation, and team leadership.
Working alongside him is Ivan Balanay, who takes on the role of QA Trainer. Balanay’s appointment is described as a move that "further supports [Testronic's] investment in developing the Testronic Academy and building the next generation of QA expertise." The Academy initiative aims to cultivate a pipeline of highly skilled testers, offering structured training programs, mentorship, and continuous professional development. By reinforcing the instructional staff, Testronic ensures that its Manila hub remains a breeding ground for cutting‑edge quality assurance practices. Chief Revenue Officer Michael Fitzgerald summed up the broader vision 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.
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." This declaration underscores a multi‑city strategy that leverages regional strengths while maintaining a cohesive, global service model. In addition to the senior leadership changes, Testronic announced earlier this month that Sonia Kerr will assume the role of Chief Executive Officer, succeeding Sharon Baylay‑Bell, who transitions to the position of company chair. This leadership transition marks a new chapter for the firm, with Kerr expected to steer the organization through its next phase of growth and innovation.
Concurrently, Michael Fitzgerald was officially named CRO, and Samantha Williams was appointed Chief Commercial Officer. Fitzgerald’s background includes a stint as a client partner at Keywords Studios, providing him with a deep understanding of client dynamics and revenue generation. Williams, previously Testronic’s global CRO and head of Europe, brings a wealth of commercial acumen and regional insight to her new role.
Collectively, these appointments reflect Testronic’s commitment to building a robust, diversified leadership team capable of navigating the rapidly evolving landscape of game development and interactive media testing. By integrating seasoned professionals from both within and outside the company, Testronic aims to enhance its service portfolio, accelerate innovation, and maintain a competitive edge in delivering high‑quality, player‑centric solutions to its worldwide clientele.
