Testronic has announced a series of high‑level appointments across its worldwide operations, signaling a strategic push to deepen its service capabilities and market reach. Central to this wave of leadership changes 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 instrumental in driving growth and nurturing key accounts.
Before that, he served as a senior business development manager, gaining valuable experience in forging strategic alliances and expanding service portfolios. Supporting Guttman's new remit, Nicole Closson has been brought on board as Business Development Manager.
Closson’s mandate is to broaden commercial coverage and provide dedicated support to partners both regionally and on a global scale. Her professional journey includes a stint as an enterprise account executive at Keywords Studios, where she managed large‑scale client engagements, and a role at Unity as senior account executive overseeing the Parsec and SyncSketch product lines. This blend of experience equips her to effectively bridge the gap between client needs and Testronic’s testing solutions.
In the European hub of Warsaw, the company has appointed Mateusz Kałuża as QA Director. Kałuża brings a wealth of senior testing experience from his previous tenure at Lionbridge Games, where he led quality assurance initiatives for multiple high‑profile gaming titles.
He emphasizes the strategic importance of Warsaw as a centre of deep QA expertise, noting, "Warsaw combines extensive testing knowledge, hands‑on experience, and a genuine understanding of what developers require from a testing partner." Kałuża added that ongoing investment in the local team will not only enhance regional capabilities but also integrate seamlessly with Testronic’s broader global network, ensuring consistent delivery standards for partners worldwide. Further strengthening the global partnership function, Lily Guerreiro joins the organization as Global Partnerships Senior Manager. Guerreiro previously served as Global Business Development Manager at Keywords Studios, where she oversaw cross‑border client acquisition and cultivated long‑term relationships with major industry players.
Her expertise in navigating complex international markets is expected to augment Testronic’s ability to secure and manage high‑value partnerships across multiple continents. The Manila Centre of Excellence, a cornerstone of Testronic’s offshore testing capacity, also sees senior talent added to its roster. Daniel Bowie Soriano steps into the role of Senior QA Manager, bringing a seasoned perspective on quality assurance processes and team leadership. Complementing him, Ivan Balanay has been appointed QA Trainer, a position that underscores Testronic’s commitment to developing its internal talent pipeline.
Balanay’s appointment is described as a key component of the company’s investment in the Testronic Academy, an initiative aimed at cultivating the next generation of QA specialists through structured training and mentorship programs. Chief Revenue Officer Michael Fitzgerald highlighted the strategic significance 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 further elaborated on the broader investment strategy, noting, "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 recent reshuffle at the highest level of the company. Earlier this month, Testronic announced the appointment of Sonia Kerr as Chief Executive Officer, succeeding Sharon Baylay‑Bell, who transitioned to the role of company chair. In addition, Michael Fitzgerald was confirmed as Chief Revenue Officer, while Samantha Williams took on the position of Chief Commercial Officer.
Fitzgerald’s background includes a client partnership role at Keywords Studios, where he honed his skills in revenue generation and client strategy. Williams, previously serving as Testronic’s global CRO and head of Europe, brings extensive experience in commercial operations and market expansion. Collectively, these appointments reflect Testronic’s deliberate focus on strengthening its leadership bench across key geographic locations and functional areas. By integrating seasoned professionals with proven track records in client partnership, business development, quality assurance, and commercial strategy, the company aims to enhance its service delivery model, accelerate growth, and reinforce its reputation as a trusted testing partner for the gaming and interactive entertainment industries.
The expanded leadership team is poised to drive forward Testronic’s mission of delivering player‑centric, partner‑first solutions that consistently meet the evolving demands of developers and publishers worldwide.
