OneStack, a fintech platform for cooperative banks, has raised $2 million in Series A funding led by Pentathlon Ventures, with participation from Yatra Angel Network and from existing investors 100Unicorns and Venture Catalysts.

The startup is expected to secure an additional $1 million as a part of the same round soon. 

OneStack, founded by Amit Kapoor and Vishal Gupta, operates as a Technical Service Provider (TSP) and Application Service Provider (ASP), offering a unified technology stack to digitize India’s cooperative banking ecosystem.

The platform offers end-to-end solutions like core banking, mobile banking, NPCI UPI Switch, and BBPS switch, allowing regional and rural banks to modernize operations and enhance services to compete with larger institutions.

Amit Kapoor, co-founder of OneStack, said, “Our mission is to make every Bharat bank a neo-bank. With this funding, we aim to extend our footprint into South and East India, targeting an additional 200+ banks to achieve a pan-India market share of 20%. Simultaneously, we will deploy our CBS across 50+ institutions and onboard 100+ banks onto our NPCI UPI & BBPS Switch, enabling them to offer UPI services under their own branding. This expansion will directly impact financial inclusion for 5 crore Indians over the next 18 months.”

With over 200 cooperative banks already onboarded, OneStack said it supports seven out of 34 state cooperative banks. OneStack offers solutions to increase CASA deposits, offer credit facilities, and deliver insurance products through a SaaS-based model.

Since its last funding round, the company has deployed over 6,000 soundboxes in 14 regional languages, improving payment connectivity in rural markets.

 Dr Apoorva Ranjan Sharma, Managing Director, Venture Catalysts, said, “OneStack’s unique positioning as a full-stack enabler for cooperative banks aligns with our vision of backing platforms that democratize access to critical infrastructure. Their ability to penetrate Tier II/III markets and deliver ROI-driven solutions positions them as a catalyst for India’s next wave of banking digitization. Our investment in OneStack resonates with our goal of backing founders who solve complex, large-scale challenges.”

 "India’s cooperative banking sector, serving over 230 million people, has long been underserved in digitization. OneStack is bridging this gap by empowering these banks with cutting-edge financial technology," Sandeep Chawda, managing partner, Pentathlon Ventures, said.
