Mumbai | February 3, 2026: OneStack, a Gurugram-based fintech startup focused on digitising India’s cooperative banking ecosystem, has raised an undisclosed amount in its ongoing Series A funding round. The round is led by Samved VC and Silicon Road Ventures, with continued participation from existing investors Pentathlon Ventures, 100Unicorns, and Venture Catalysts. The company also noted interest from multiple global investors.
Founded in 2019 by Amit Kapoor and Vishal Gupta, OneStack offers a SaaS-based digital banking infrastructure platform tailored for cooperative banks and credit societies. The company currently serves over 200 cooperative institutions across India and aims to scale this network to 500 banks over the next two years.
OneStack processes more than ₹750 crore in annual UPI transaction value through its payments stack and is on track to cross ₹1,000 crore in UPI transactions by the end of the current financial year.
The fresh capital will be utilised to expand OneStack’s end-to-end digital banking offerings, which include mobile banking applications, UPI and QR-based payments, SoundBox integrations, Bharat Bill Payment System (BBPS) services, and cooperative-focused core banking solutions.
The startup had previously raised $2 million in March 2025 in a round led by Pentathlon Ventures, with participation from Yatra Angel Network, 100Unicorns, and Venture Catalysts. Including the latest round, OneStack has raised approximately $4.24 million to date.
India’s cooperative banking sector, comprising over 1.1 lakh institutions and managing consolidated assets of nearly ₹24.5 lakh crore, is undergoing a technology-led transformation. The Reserve Bank of India’s increased regulatory focus on governance, compliance, and core banking adoption has accelerated demand for cost-effective, regulator-aligned digital platforms, particularly among urban cooperative banks operating at sub-scale levels.
“OneStack has evolved from a mobile banking provider into a full-stack technology partner for cooperative banks,” said Amit Kapoor, Co-founder, OneStack. “Regulatory expectations around digital infrastructure and governance have risen sharply. This funding will help us scale our platform and support more cooperative institutions modernise efficiently.”
Amit Srivastava, Managing Partner at Samved VC, said OneStack has built a “compliant and scalable SaaS platform specifically designed for cooperative banks, a segment that remains under-digitised despite its systemic importance.”
Sid Mookerji, Managing Partner at Silicon Road Ventures, added that OneStack’s deep understanding of cooperative banking workflows and regulatory constraints positions it well for large-scale adoption.
