Testronic has announced a series of high‑level appointments across its worldwide operations, underscoring the company’s commitment to strengthening its leadership pipeline and expanding its service capabilities. Among the most notable additions is Mike Guttman, who has been promoted to Vice President of Senior Partnerships.
In this role, Guttman will be responsible for cultivating and overseeing strategic relationships with the firm’s most important clients, ensuring that Testronic’s testing and quality‑assurance solutions remain closely aligned with partner needs. Guttman arrives at Testronic with a robust background in client management and business development.
Prior to joining the company, he held the position of client partner at Keywords Studios, where he was instrumental in driving growth across multiple entertainment and technology accounts. He also served as a senior business development manager, gaining extensive experience in negotiating complex contracts and delivering tailored service offerings. This blend of strategic insight and hands‑on execution makes him a natural fit for steering senior partnerships at a firm that prides itself on a player‑focused, partner‑first philosophy.
Supporting Guttman’s efforts is Nicole Closson, who has been hired as a Business Development Manager. Closson’s mandate is to broaden commercial coverage and provide additional support to partners both regionally and on a global scale.
She brings a wealth of experience from her previous tenure at Keywords Studios, where she excelled as an enterprise account executive, as well as from Unity, where she acted as a senior account executive for the Parsec and SyncSketch products. Her deep understanding of the gaming and interactive media landscape will help Testronic extend its reach into new markets and deepen existing relationships.
In Europe, the company’s Warsaw office has seen a key leadership change with the appointment of Mateusz Kałuża as QA Director. Kałuża’s career has been anchored in senior testing positions at Lionbridge Games, where he honed his expertise in quality assurance processes for high‑profile game releases. Speaking about his new role, Kałuża highlighted Warsaw’s reputation as a hub of QA talent, noting that the city “brings together deep QA expertise, experience and a real understanding of what developers need from a testing partner.” He added that Testronic’s ongoing investment in the local team will enable the office to integrate more fully with the organization’s global capabilities, delivering consistent, high‑quality outcomes for partners regardless of their geographic location. Further strengthening the global partnership function, Lily Guerreiro has joined the firm as Global Partnerships Senior Manager.
Guerreiro previously served as Global Business Development Manager at Keywords Studios, where she was responsible for scaling the company’s international client base. Her experience in navigating cross‑border business development will be valuable as Testronic seeks to deepen its relationships with multinational publishers and developers. The Manila Centre of Excellence, a critical node in Testronic’s service network, has also welcomed senior talent. Daniel Bowie Soriano has been appointed Senior QA Manager, bringing a seasoned perspective on testing workflows and team leadership.
Alongside him, Ivan Balanay has taken on the role of QA Trainer, a position that supports the company’s investment in the Testronic Academy—a training initiative designed to cultivate the next generation of QA specialists. Balanay’s appointment is described as a move that “further supports [the] investment in developing the Testronic Academy and building the next generation of QA expertise,” emphasizing the firm’s focus on continuous skill development.
Chief Revenue Officer Michael Fitzgerald commented on the broader strategic implications of 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 went on to explain that the recent investments in New Orleans, Warsaw, and Manila, in addition to the established presence in London, “further strengthen the expertise available to our partners.” Fitzgerald believes that by continuing to invest in top‑tier talent, Testronic can deliver an “exceptional Player‑Focused, Partner‑First and Outcomes‑Led service” to its clients. These leadership changes come on the heels of a significant reshuffle at the executive level earlier in the month.
Sonia Kerr was named Chief Executive Officer, succeeding Sharon Baylay‑Bell, who transitioned to the role of company chair. In tandem with Kerr’s appointment, Michael Fitzgerald was confirmed as Chief Revenue Officer, while Samantha Williams took on the position of Chief Commercial Officer. Fitzgerald’s background includes a stint as a client partner at Keywords Studios, whereas Williams previously served as Testronic’s global CRO and head of Europe, bringing internal continuity to the commercial strategy.
Overall, Testronic’s recent hiring spree signals a deliberate effort to reinforce its global footprint, deepen its expertise in quality assurance, and enhance the strategic alignment between its service offerings and partner expectations. By placing seasoned professionals in key regional hubs and central leadership positions, the company is positioning itself to meet the evolving demands of the gaming and interactive media sectors, ensuring that developers receive reliable, high‑quality testing support throughout the product lifecycle.
The expanded leadership team is expected to drive further growth, foster innovation in testing methodologies, and maintain the high standards that Testronic’s partners have come to rely upon.
