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. At the forefront of these changes is the appointment of Mike Guttman as Vice President of Senior Partnerships, a role that will see him spearheading strategic relationships with the firm’s most significant clients.
Guttman arrives at Testronic after a distinguished tenure at Keywords Studios, where he served as a client partner, and after holding a senior business development manager position that gave him deep insight into the gaming and interactive media sectors. His experience in cultivating large‑scale partnerships and driving revenue growth makes him a natural fit for the senior‑partnerships portfolio, where he will be responsible for aligning Testronic’s testing capabilities with the evolving needs of top‑tier developers and publishers.
Joining Guttman in the business development arena is Nicole Closson, who steps into the role of Business Development Manager. Closson’s mandate is to broaden commercial coverage and provide additional support to partners both regionally and globally.
She previously worked at Keywords Studios as an enterprise account executive and spent time at Unity, where she served as senior account executive for the Parsec and SyncSketch products. Her background in enterprise sales and her familiarity with the tools that developers rely on position her to enhance Testronic’s market reach and deepen client engagement.
In the company’s European hub, Warsaw, Testronic has named Mateusz Kałuża as QA Director. Kałuża brings a wealth of experience from his previous senior testing roles at Lionbridge Games, where he oversaw complex quality‑assurance projects for high‑profile titles. Speaking about his new role, Kałuża highlighted Warsaw’s reputation as a centre of testing 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." The global partnerships function also receives a boost with the addition of Lily Guerreiro, who assumes the position of Global Partnerships Senior Manager. Guerreiro previously held the title of Global Business Development Manager at Keywords Studios, where she managed cross‑border relationships and helped shape the company’s international growth strategy.
Her global perspective and proven track record in partnership development will be instrumental in aligning Testronic’s services with the strategic goals of its worldwide client base. Testronic’s Centre of Excellence in Manila has similarly been reinforced with senior talent. Daniel Bowie Soriano joins as Senior QA Manager, bringing extensive experience in quality assurance leadership, while Ivan Balanay takes on the role of QA Trainer.
Balanay’s appointment is described as a move to "further support our investment in developing the Testronic Academy and building the next generation of QA expertise." The Academy aims to cultivate a pipeline of skilled testers, ensuring that the company can meet the increasing demand for high‑quality, rapid‑turnaround testing services. Chief Revenue Officer Michael Fitzgerald commented on the strategic significance of these appointments: "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." 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, and Samantha Williams was appointed 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 deep institutional knowledge to her new role.
Overall, Testronic’s recent appointments signal a deliberate strategy to deepen expertise across its geographic locations, enhance its leadership depth, and position the company as a premier testing partner for the gaming industry. By integrating seasoned professionals with proven track records in business development, quality assurance, and partnership management, Testronic aims to deliver a seamless, high‑quality testing experience that aligns with the fast‑moving demands of modern game development.
The expanded senior team is expected to drive further growth, foster stronger client relationships, and reinforce Testronic’s reputation as a global leader in QA services.
