TransBnk: 10 Key Things You Must Know

Overview

TransBnk is an innovative banking infrastructure startup based in Mumbai, India, revolutionizing the landscape of global transaction banking through its pioneering API-first platform. Founded in 2022 by industry veterans Vaibhav Tambe, Lavin Kotian, Pulak Jain, and Sachin Gupta, TransBnk provides a unified, secure, and scalable transaction banking ecosystem that caters primarily to corporate, commercial, and institutional clients. By integrating multiple banks under a single interface, the company empowers enterprises, fintechs, and non-banking financial companies (NBFCs) to conduct seamless transactions, escrow management, cash flow automation, and reconciliation. As India’s corporate banking sector lags behind retail banking in digitization, TransBnk is leading the charge to bridge this gap, modernizing how businesses handle financial processes across borders and ecosystems. The following sections uncover ten key facets that shed light on TransBnk’s origin, technology, market impact, and growth trajectory.

1. Founding and Leadership Expertise

TransBnk was founded in 2022 by four leading figures with extensive backgrounds in banking and financial technology: Vaibhav Tambe (CEO), Lavin Kotian (CTO), Pulak Jain (CBO), and Sachin Gupta (CPO). Collectively, the founders bring over 30 years of domain expertise specifically in corporate banking and transaction banking, allowing them to design solutions grounded in deep industry understanding. This strong leadership team underpins TransBnk’s rapid early success and innovative approach to reimagining banking infrastructure.

2. The Problem in Corporate Banking

While India’s retail banking sector has seen exponential digital growth, particularly due to innovations like the Unified Payments Interface (UPI), corporate banking remains fragmented and reliant on manual systems such as spreadsheets and relationship manager calls. Corporates face challenges navigating multiple banking interfaces and fragmented accounts, limiting efficiency and transparency. TransBnk addresses these pain points by offering a single-window programmable interface that consolidates banking operations across multiple institutions, dramatically simplifying transaction handling and reconciliation.

3. API-First Platform and Modular Architecture

Central to TransBnk’s solution is its API-led platform that enables businesses and financial firms to integrate seamlessly with over 40 partner banks, including private, public, multinational, and small finance banks. This modular Software-as-a-Service (SaaS) infrastructure allows clients to onboard quickly, manage payments, lending, escrow accounts, and other treasury services efficiently. This move away from legacy, capital-intensive, monolithic banking technology enables faster deployment, operational flexibility, and cost-effectiveness.

4. Comprehensive Transaction Banking Solutions

TransBnk offers a wide array of transaction banking products tailored to diverse needs: digital lending platforms, escrow management as a service, repayment hubs, supply chain finance solutions, and capital market services. Escrow-as-a-service is a critical capability, simplifying complex escrow processes and reducing onboarding turn-around-time for startups and lenders, thereby enhancing transparency and trust within the financial ecosystem.

5. Strategic Industry Partnerships

The company has forged strong collaborations with leading banks and financial institutions, including Federal Bank, Bajaj Finserv, and Aditya Birla Finance Ltd., to jointly improve transactional security and efficiency. These partnerships play a pivotal role in enhancing customer experience and building credibility through compliance and trust, critical components in regulated banking environments.

6. Rapid Growth and Funding Milestones

TransBnk has witnessed remarkable growth, scaling from a seed-funded startup to a major fintech infrastructure player within just a few years. The company secured a $4 million Series A round in 2024 led by 8i Ventures, followed by a $25 million Series B funding round in 2025 spearheaded by Bessemer Venture Partners, with participation from other prominent investors like Arkam Ventures, Fundamentum Partnership, Accion Venture Labs, and GMO Venture Partners. This influx of capital supports product innovation, geographical expansion, and talent acquisition.

7. Scalability and Transaction Volume

Currently, TransBnk serves over 220 clients including fintechs, NBFCs, and corporate entities, processing nearly 1,500 API interactions per month. Their infrastructure handles approximately 110 million transactions monthly across 11,000 bank accounts, demonstrating scalability and robustness. The platform is built to handle over 2,500 transactions per second, reflecting readiness for high-volume transaction environments.

8. Strategic Global Expansion Plans

Leveraging the recent funding rounds, TransBnk is preparing to expand beyond India’s borders to key financial hubs in Southeast Asia and the Middle East. This expansion aims to provide cutting-edge transaction banking infrastructure in markets with similar needs for modernization and digitization, extending TransBnk’s vision of delivering seamless and agile global banking services.

9. Focus on Compliance and Security

TransBnk’s platform is designed with a compliance-first mindset, adhering to the stringent requirements of regulated banking entities. By building a secure, transparent infrastructure that strengthens governance around escrow management, lending, and transaction processing, TransBnk ensures that financial institutions can confidently operate within evolving regulatory frameworks without sacrificing operational efficiency.

10. Profitable and Sustainable Business Model

Defying common fintech challenges, TransBnk achieved profitability within two years of its inception, underscoring the capital efficiency and scalability of its SaaS-based banking infrastructure model. With gross margins approaching 80%, the firm continues to attract industry attention for its unique approach to bridging fintech and traditional banking. The founders emphasize product-led growth with zero reliance on ads, setting a benchmark for sustainable startup innovation in financial services.

Conclusion

TransBnk exemplifies the transformative potential of fintech in reengineering the global transaction banking landscape. Backed by expert leadership, robust technology, and significant financial backing, the company is bridging the longstanding digital divide in corporate banking while securing a strong foothold in India and beyond. Its API-centric, modular infrastructure promises to usher in a new era of seamless, efficient, and secure transaction banking designed for the digital economy. As TransBnk scales new heights, it poses a compelling question for the future: how might these innovations reshape global banking norms and ultimately empower businesses worldwide?
