Silverthorne brings more than three decades of experience spanning operational tax, regulatory frameworks, and financial services. His career includes senior roles across both the public and private sectors, having worked with leading institutions such as NatWest Group, HSBC, PwC, and the UK’s tax authority, HMRC. This cross-sector experience positions him uniquely to navigate the complexities of global tax compliance and regulatory requirements.
In his new role, Silverthorne will lead GTN’s tax services strategy, with a focus on enabling clients to expand into new jurisdictions without the burden of building and maintaining their own automated tax and regulatory infrastructure. His mandate reflects a growing demand among financial institutions and fintech firms for integrated, scalable solutions that reduce operational friction while ensuring compliance across multiple markets.
GTN emphasized that the appointment aligns with its broader vision of transforming tax infrastructure from a traditional back-office function into a strategic driver of competitive advantage. By embedding tax and regulatory capabilities into its platform, the company aims to help clients accelerate market entry, streamline operations, and enhance overall efficiency.
Silverthorne’s expertise is expected to play a critical role in advancing this vision. Having operated “on both sides of the table” — within regulatory bodies and global financial institutions — he brings a comprehensive understanding of compliance expectations, risk management, and the operational challenges faced by firms expanding internationally.
The move comes at a time when financial services providers are increasingly prioritizing automation and regulatory technology (RegTech) to manage complex cross-border requirements. As firms scale globally, the ability to seamlessly handle tax obligations and reporting standards has become a key differentiator, particularly in highly regulated markets.
By strengthening its leadership team with seasoned professionals like Silverthorne, GTN continues to position itself as a partner of choice for institutions seeking to navigate the evolving global financial landscape. The company’s focus on integrating tax services into its broader infrastructure offering underscores a shift in how financial firms approach compliance — not merely as a necessity, but as an enabler of growth.
Silverthorne’s appointment marks another step in GTN’s ongoing efforts to expand its global capabilities and deliver end-to-end solutions that support clients at every stage of their international expansion journey.
