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. Among the most notable additions is Mike Guttman, who has been named Vice President of Senior Partnerships. In this capacity, Guttman will oversee the cultivation and growth of strategic relationships with key clients, ensuring that Testronic’s portfolio of testing and quality assurance solutions continues to meet the evolving demands of the gaming and interactive entertainment sectors.
Before joining Testronic, Guttman accumulated extensive experience in the industry, most prominently as a client partner at Keywords Studios, where he was responsible for managing large‑scale accounts and driving revenue growth across multiple regions. He also held the role of Senior Business Development Manager, a position that sharpened his ability to identify market opportunities, negotiate complex contracts, and align service delivery with client expectations. His track record of delivering measurable results and building long‑lasting partnerships makes him a fitting choice to lead Testronic’s senior partnership initiatives. Supporting Guttman’s efforts is Nicole Closson, who steps into the role of Business Development Manager.
Closson’s mandate is to broaden commercial coverage and provide dedicated support to partners both within her regional focus and on a global scale. Her background includes a tenure at Keywords Studios as an Enterprise Account Executive, where she managed high‑value accounts and drove cross‑sell initiatives. She also spent time at Unity, serving as Senior Account Executive for the Parsec and SyncSketch products, giving her a deep understanding of the tools and workflows that modern developers rely on. Together, Guttman and Closson form a leadership duo aimed at delivering a seamless, partner‑centric experience.
In Europe, Testronic’s Warsaw office has seen a strategic promotion with Mateusz Kałuża taking on the role of QA Director. Kałuża brings a wealth of senior testing experience from his previous position at Lionbridge Games, where he led teams responsible for functional, regression, and performance testing across a variety of platforms.
Speaking about the appointment, Kałuża emphasized Warsaw’s growing reputation as a hub of QA expertise: "Warsaw brings together deep QA knowledge, hands‑on experience, and a genuine 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 leadership is expected to further integrate Warsaw’s talent pool with Testronic’s global network, enhancing service consistency and quality.
Adding to the European leadership roster, Lily Guerreiro joins as 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 in emerging markets and forging strategic alliances with major publishers.
Her experience in navigating complex, multi‑regional deals will be valuable as Testronic seeks to deepen its relationships with existing partners while attracting new business. The company’s Centre of Excellence in Manila also receives a boost in senior talent. Daniel Bowie Soriano has been appointed Senior QA Manager, a role that will see him oversee the day‑to‑day execution of testing projects, mentor junior staff, and ensure that the Manila hub adheres to Testronic’s rigorous quality standards.
Complementing Soriano’s appointment is Ivan Balanay, who steps into the position of QA Trainer. Balanay’s responsibilities include developing and delivering training curricula that upskill the Manila team, thereby supporting the broader objective of building the next generation of QA expertise.
The company highlighted that Balanay’s addition "further supports our investment in developing the Testronic Academy and building the next generation of QA expertise." Chief Revenue Officer Michael Fitzgerald commented on the strategic significance 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. 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 highlight the company’s philosophy of leveraging localized talent while maintaining a cohesive, global service model. Earlier in the month, Testronic announced a change at the very top of its hierarchy: Sonia Kerr was appointed Chief Executive Officer, succeeding Sharon Baylay‑Bell, who transitioned to the role of company chair.
This leadership transition marks a new chapter for the organization, with Kerr expected to steer the company through continued growth and diversification. In tandem with Kerr’s appointment, the executive team was further expanded.
Michael Fitzgerald, previously a client partner at Keywords Studios, was confirmed as Chief Revenue Officer, while Samantha Williams took on the role of Chief Commercial Officer. Williams, who previously served as Testronic’s global CRO and head of Europe, brings a deep understanding of market dynamics and commercial strategy to her new position. Collectively, these appointments reflect Testronic’s strategic emphasis on building a robust, experienced leadership cadre capable of delivering high‑quality QA services across multiple continents.
By investing in seasoned professionals with proven track records, the company aims to enhance its operational excellence, foster stronger client relationships, and sustain its reputation as a premier testing partner in the interactive entertainment industry.
