Testronic has recently undertaken a series of high‑level appointments across its worldwide operations, underscoring the company’s commitment to expanding its leadership bench and enhancing service delivery for game developers and publishers. Central to this wave of senior hires is the promotion of Mike Guttman to the role of Vice President of Senior Partnerships, a position that places him at the forefront of cultivating strategic relationships with the firm’s most important clients.
Mike Guttman arrives at Testronic with a robust background in client partnership and business development. Prior to joining the company, he spent several years at Keywords Studios, where he acted as a client partner, helping to align the studio’s testing capabilities with the needs of large‑scale developers.
He also held a senior business development manager role, giving him a deep understanding of how to grow revenue streams while maintaining strong, collaborative ties with partners. In his new capacity, Guttman will be responsible for overseeing the senior partnership portfolio, ensuring that Testronic’s most valuable relationships receive the strategic attention and customized support required to thrive in an increasingly competitive market.
Supporting Guttman’s efforts is Nicole Closson, who has been brought on board as a Business Development Manager. Closson’s mandate is to broaden commercial coverage and provide additional support to partners both regionally and globally.
She brings a wealth of experience from her previous tenure at Keywords Studios, where she served as an enterprise account executive, and from her time at Unity, where she worked as a senior account executive handling key accounts such as Parsec and SyncSketch. Her expertise in managing enterprise‑level accounts and navigating complex sales cycles will be instrumental in extending Testronic’s reach and deepening its engagement with existing and prospective clients.
In the European hub of Warsaw, Testronic has appointed Mateusz Kałuża as the new QA Director. Kałuża’s career has been built on senior testing positions at Lionbridge Games, where he honed his skills in quality assurance leadership and built a reputation for delivering rigorous testing solutions. Speaking about his new role, Kałuża highlighted Warsaw’s strategic importance: "The city combines deep QA expertise, a strong understanding of developer needs, and a culture that values precision. Our ongoing investment in the local team will allow us to fuse this talent with Testronic’s global capabilities, ensuring consistent, high‑quality outcomes for partners wherever they operate." Adding to the senior leadership roster, Lily Guerreiro has been named Global Partnerships Senior Manager.
Guerreiro’s previous experience includes a stint as Global Business Development Manager at Keywords Studios, where she was responsible for driving growth across multiple international markets. Her appointment signals Testronic’s intent to strengthen its global partnership network and to provide a unified, strategic approach to client engagement across continents. The Manila Centre of Excellence, a critical node in Testronic’s global testing network, also received two senior appointments. Daniel Bowie Soriano joins as Senior QA Manager, bringing a track record of leading testing teams and implementing best‑practice processes that improve defect detection rates and accelerate release cycles.
Alongside him, Ivan Balanay steps into the role of QA Trainer, a position that directly supports the development of the Testronic Academy. Balanay’s focus will be on designing and delivering training programs that upskill QA professionals, ensuring the Academy continues to produce the next generation of testing talent equipped with the latest methodologies and tools. Chief Revenue Officer Michael Fitzgerald commented on the broader 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." Fitzgerald’s remarks reflect a strategic vision that goes beyond mere geographic expansion. By embedding senior talent in each key location, Testronic aims to create a seamless, end‑to‑end service model where local insights are amplified by global resources. This model is designed to address the nuanced demands of modern game development, from early‑stage concept testing to post‑launch live‑ops support.
Earlier in the month, the company announced a change at the very top of its leadership hierarchy. Sonia Kerr was appointed Chief Executive Officer, succeeding Sharon Baylay‑Bell, who transitioned to the role of company chair. This leadership shift is part of a broader realignment that also saw Michael Fitzgerald officially take on the CRO title, while Samantha Williams was promoted to Chief Commercial Officer. Fitzgerald previously served as a client partner at Keywords Studios, bringing a deep understanding of the outsourcing landscape, whereas Williams held the position of Global CRO and head of Europe for Testronic, giving her a comprehensive view of the company’s commercial operations worldwide.
Collectively, these appointments represent a concerted effort by Testronic to reinforce its leadership depth, broaden its geographic footprint, and enhance the quality of its service offerings. By aligning seasoned professionals with strategic regional hubs, the company is positioning itself to meet the evolving expectations of developers who demand rapid, reliable, and player‑centric testing solutions.
The expanded senior team is expected to drive further innovation, improve operational efficiency, and ultimately deliver greater value to Testronic’s growing roster of partners across the gaming industry.
