Testronic has announced a series of high‑level appointments across its worldwide operations, signaling a strategic push to deepen its service capabilities and broaden its 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's new position places him at the forefront of cultivating and managing relationships with the company’s most important clients and strategic allies. Before joining Testronic, Guttman amassed extensive experience in the interactive entertainment and outsourcing sectors.
He spent several years as a client partner at Keywords Studios, where he was responsible for overseeing major accounts and driving growth through tailored service offerings. Prior to that, he held a senior business development manager role, sharpening his skills in market analysis, partnership negotiations, and revenue generation.
His track record of building robust client pipelines and delivering measurable results makes him a natural fit for steering Testronic’s senior partnership initiatives. Complementing Guttman's appointment is the addition of 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 the region and on a global scale. She brings a wealth of experience from her previous positions at Keywords Studios, where she served as an enterprise account executive, and at Unity, where she was a senior account executive handling high‑profile accounts such as Parsec and SyncSketch.
Her deep understanding of enterprise‑level negotiations and her proven ability to nurture long‑term client relationships are expected to reinforce Testronic’s market penetration and service delivery. In the European hub of Warsaw, Testronic has promoted Mateusz Kałuża to the position of QA Director. Kałuża arrives with a solid background in quality assurance, having held senior testing roles at Lionbridge Games. He emphasizes the strategic importance of Warsaw as a centre of QA 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." His leadership is expected to harmonize local talent with the company’s broader global QA framework, ensuring consistent, high‑quality testing outcomes for clients worldwide. Further strengthening the global partnership team, Lily Guerreiro joins as Global Partnerships Senior Manager.
Guerreiro previously held the title of Global Business Development Manager at Keywords Studios, where she managed cross‑border client engagements and contributed to the expansion of the firm’s international footprint. Her expertise in aligning business development strategies with operational execution will be instrumental in fostering collaborative ventures and driving growth across Testronic’s worldwide network. The Manila Centre of Excellence, a critical node in Testronic’s service delivery model, also welcomes two senior figures. Daniel Bowie Soriano steps in as Senior QA Manager, bringing a robust background in quality assurance leadership.
Alongside him, Ivan Balanay takes on the role of QA Trainer, a position that underscores Testronic’s commitment to nurturing the next generation of testing professionals. The company highlighted that Balanay’s appointment "further supports our investment in developing the Testronic Academy and building the next generation of QA expertise," reflecting an ongoing dedication to skill development and knowledge transfer within the organization. Chief Revenue Officer Michael Fitzgerald articulated the broader strategic vision behind 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 comments highlight a multi‑regional approach that leverages localized expertise while maintaining a cohesive global service standard. Earlier in the month, Testronic also announced a change at the helm of the company. Sonia Kerr was appointed Chief Executive Officer, succeeding Sharon Baylay‑Bell, who transitioned to the role of company chair.
This leadership transition is part of a broader restructuring that includes the appointment of Michael Fitzgerald as Chief Revenue Officer and Samantha Williams as 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 industry insight to their new roles. Collectively, these appointments illustrate Testronic’s deliberate strategy to reinforce its leadership bench, expand its geographic reach, and deepen its expertise across key markets.
By integrating seasoned professionals with proven track records in client partnership, business development, and quality assurance, the company aims to deliver a more cohesive, responsive, and high‑quality service experience for its partners. The emphasis on regional Centres of Excellence—particularly in New Orleans, Warsaw, and Manila—signals a commitment to localized talent development while maintaining a unified global operational framework.
As Testronic continues to invest in both people and processes, it positions itself to meet the evolving demands of the gaming and interactive entertainment industries, ensuring that partners receive a player‑focused, outcomes‑driven approach that aligns with the fast‑changing market dynamics.
