Testronic has announced 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 clients. Central to this wave of promotions is the elevation of Mike Guttman to the role of Vice President of Senior Partnerships. In this capacity, Guttman will oversee the cultivation of strategic relationships with key partners and drive growth initiatives across Testronic’s global network. Guttman arrives at Testronic with a robust background in the interactive entertainment services sector.
He previously held the position of client partner at Keywords Studios, where he was responsible for managing large‑scale accounts and aligning service offerings with the evolving needs of game developers. Prior to that, he served as a senior business development manager, gaining extensive experience in negotiating complex contracts and forging long‑term collaborations.
His deep industry knowledge and proven track record in partnership development make him a natural fit for steering Testronic’s senior partnership strategy. Supporting Guttman’s efforts is Nicole Closson, who joins the team as Business Development Manager.
Closson’s mandate is to broaden commercial coverage and provide dedicated support to partners both regionally and worldwide. She brings a wealth of experience from her previous roles at Keywords Studios, where she excelled as an enterprise account executive, and at Unity, where she acted as senior account executive for the Parsec and SyncSketch products. Her expertise in managing enterprise‑level accounts and her familiarity with cutting‑edge development tools will help Testronic deepen its engagement with existing clients while attracting new business. In the European hub of Warsaw, Testronic has appointed Mateusz Kałuża as QA Director.
Kałuża’s appointment follows a distinguished tenure in senior testing positions at Lionbridge Games, where he honed his skills in quality assurance leadership and process optimization. Speaking about his new role, Kałuża highlighted Warsaw’s reputation as a centre of QA excellence, noting that the city offers a blend of technical proficiency and an intuitive grasp of what developers require from a testing partner. He emphasized that continued investment in the local team will enable Testronic to merge regional expertise with its broader global capabilities, ensuring consistent, high‑quality outcomes for partners regardless of location. Adding to the senior leadership roster, Lily Guerreiro steps in 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 across multiple continents. Her global perspective and experience in scaling partnership programs will be valuable as Testronic seeks to deepen relationships with existing clients and explore new market opportunities.
The Manila Centre of Excellence also sees significant reinforcement. Daniel Bowie Soriano has been appointed Senior QA Manager, bringing a strategic vision for quality assurance that aligns with Testronic’s broader objectives.
Alongside him, Ivan Balanay joins as QA Trainer, a role that directly supports the development of the Testronic Academy and the cultivation of the next generation of QA talent. The company highlighted Balanay’s appointment as a key component of its investment in training and professional development, ensuring that the Manila team remains at the forefront of industry best practices. Chief Revenue Officer Michael Fitzgerald commented on the strategic importance 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 noted that the recent investments in New Orleans, Warsaw, and Manila, together with an established presence in London, significantly augment the pool of expertise available to Testronic’s partners. By continuing to attract and develop outstanding professionals, the company aims to deliver a service model that is player‑focused, partner‑first, and outcomes‑led.
These leadership changes come on the heels of a broader executive reshuffle earlier in the month. Sonia Kerr was appointed 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 role of Chief Commercial Officer. Fitzgerald previously served as a client partner at Keywords Studios, bringing valuable insight into client management and revenue growth, whereas Williams held the position of global CRO and head of Europe at Testronic, equipping her with a comprehensive understanding of the company’s commercial strategy.
Overall, Testronic’s recent appointments reflect a deliberate strategy to strengthen its leadership across key geographic locations, enhance its service capabilities, and reinforce its commitment to delivering high‑quality testing and development support to the gaming industry. By integrating seasoned professionals with diverse backgrounds in business development, quality assurance, and partnership management, Testronic positions itself to meet the evolving demands of developers and publishers worldwide, ensuring that its partners receive the expertise and support necessary to succeed in an increasingly competitive market.
