Overchain has expanded its senior team after reporting average monthly payment processing volume of more than $385 million.
The Toronto-based company has appointed Mansi Birla as Head of Licensing, John Grimsey as Chief Technology Officer, and David Benton as Head of Enterprise Sales.
The company launched in late 2025. Since then, its total payment volume has grown by an average of 38% quarter on quarter, according to Overchain. Stablecoins now account for 86% of the transactions processed through the platform.
The three hires cover areas the company will need as it takes on more clients and enters additional markets: regulatory approvals, technology development and sales to large businesses. Overchain describes its platform as an operating layer for digital money movement.
It combines stablecoin settlement, treasury operations, OTC trading and compliance tools in one place. Clients can send and receive stablecoins and convert funds into fiat for settlement through their existing banks.
Birla joins from Gemini, where she worked on licensing and international expansion across the U.S., the EU and offshore financial centers. She was responsible for both retail and institutional business lines and led the regulatory workstream for Gemini’s CFTC Designated Contract Market license. At Overchain she will focus on securing licenses in new jurisdictions to support growing international client demand.
Grimsey takes the CTO role. He specializes in designing and scaling trading and financial infrastructure, with a focus on post-trade settlement. In his previous role at BCB Group, his architectural work supported a doubling of daily trade settlement volume before the company introduced full Straight-Through Processing.
At Overchain he will oversee the continued development of the platform’s technology, including capacity, resilience, and the company’s AI strategy.
Benton will lead enterprise sales. He has worked at IBM and Accenture, where he dealt with large businesses and helped take IBM’s blockchain platform to market. His previous roles also include Currencycloud, which Visa later acquired, and Cashflows.
At Overchain he is responsible for enterprise sales and strategic client relationships as the company tries to expand adoption among international businesses.
CEO Sam Shields said stablecoins are becoming a more important part of how businesses move money globally. He said Overchain was built so companies can use that infrastructure at scale without having to handle the operational complexity themselves.
“The growth we’ve seen over the past 12 months shows real-world demand,” Shields said. “Mansi, John and David bring deep experience across regulation, financial infrastructure and enterprise technology. That strengthens the team as we scale the platform, expand internationally and support more businesses.”
Overchain says it has seen interest from companies that want to use stablecoins for international payments but do not want to manage the operational and compliance work themselves. Its clients include firms in financial services, luxury markets and digital platforms.
The platform is set up so businesses can receive and send value in stablecoins and automatically convert to or from fiat for settlement through their existing banking infrastructure. Overchain says compliance is built into the system, which it argues helps clients reduce the cost and friction of moving money across borders.
The new appointments come as the company looks to grow both its platform and its international footprint. Overchain has not said which new markets it plans to enter next, but the hiring of a dedicated licensing lead suggests regulatory approvals will be a priority as volume continues to rise.
For now, the three hires give Overchain more capacity in technology, regulation and enterprise sales as it tries to turn early growth into a larger international business.
