Mumbai, August 28, 2025: Banking infrastructure platform TransBnk today announced its $25 million Series B Fundraise led by Bessemer Venture Partners with participation from Arkam Ventures and Fundamentum Partnership, with participation from existing investors 8i Ventures, Accion Venture Labs, GMO Venture Partners. The funds will primarily be used for geographical expansion and bolstering tech & Product talent.
Founded in 2022 by Vaibhav Tambe, Lavin Kotian, Pulak Jain and Sachin Gupta, TransBnk is building a common operating system for fintechs and other institutions to access the banking ecosystem. Their ‘single-window’ offering allows clients to leverage API infrastructure from various banks for seamless onboarding, transactions and reconciliations.
Over the past decade, there has been much tech-first innovation on the retail banking side that has made consumer journeys nimble and seamless. Corporate & business banking, however, has long lagged behind the innovation seen in retail banking. There is a gaping void in how corporations and lenders manage their digital banking operations, especially when it comes to navigating a fragmented ecosystem of accounts, interfaces, and manual processes. While retail users enjoy seamless, mobile-first banking journeys, corporate customers often rely on spreadsheets, RM calls, and multiple portals just to get basic tasks done. This is the gap which TransBnk aims to plug, by embedding itself directly into the core infrastructure of banks, enabling companies to view, transact, and reconcile across their multiple banking relationships in one unified, programmable interface.
TransBnk aims to capitalise on a larger industry trend - banks are moving away from monolithic, capex-heavy software stacks. Legacy providers are costly and can take years to implement, often delivering clunky and fragmented solutions. TransBnk offers an opex-led, modular alternative, starting with payment and lending rails, and potentially evolving into a full customer engagement layer or even a next-gen core for corporate banking. TransBnk therefore delivers modern infrastructure that is highly technical and complex, while demonstrating strong capital efficiency and profitability at this early stage, aiming to be the backbone of India’s corporate banking future. This allows banks to also upgrade their tech-stack to remain relevant and competitive.
TransBnk’s unique value proposition has translated into robust business metrics. They have grown from seed to double digit million in annual dollar revenue in less than 24 months. They have also integrated with 40+ banks, which include leading private and public sector players, MNC Banks as well as Small Finance Banks. They have more than 220 clients accessing nearly 1500 APIs on a monthly basis.
What sets the founding team apart is their deep experience in the field of corporate banking as well as transaction banking - a niche, specialized, and highly relationship-driven space, and the founders bring over 7 decades of collective experience in this domain.
Vishal Gupta, Partner, Bessemer Venture Partners said “We are excited to partner with the Transbnk team. Their deep industry expertise makes them best placed to disrupt corporate banking and transaction banking in India, making it more seamless and reducing fragmentation. Corporate banking has lagged behind their retail counterparts, where over the past 10 years innovation in this space has allowed users to enjoy frictionless, mobile-first banking journeys. We are confident that Transbnk will bring the same transformative spirit and user delight to the corporate and transaction banking ecosystem”
Vikram Chachra of 8i ventures said “We’re thrilled to welcome Bessemer, Fundamentum, and Arkam to the TransBnk family. When we led the seed round, we believed TransBnk could become the new foundational layer for corporate banking in India. Just two years later, it has emerged as India’s fastest-growing fintech infrastructure platform, putting banks back at the centre of the fintech landscape and enabling them to serve a new generation of digital-first businesses.”
Vaibhav Tambe, CEO and co-founder, TransBnk commented that “Series B is a massive growth catalyst—fueling our roadmap to scale, innovate, and set new benchmarks in global transaction banking. Our proprietary tech Infra is already powering leading NBFCs, Fintech players, Banks, Corporates and we are now expanding this across BFSI, Mid-Corporate & SMEs. TransBnk is strategically placed to expand beyond India, with encouraging traction in SEA and Middle East markets, while at the same time focused on consolidating our strength in the domestic market as an emerging leader in banking infrastructure.”
