Fintech Startup OneStack Secures New Capital to Accelerate Digital Transformation of Cooperative Banks Across India

OneStack, an Indian fintech startup focused on transforming the cooperative banking sector through digital solutions, has raised fresh funding in its ongoing Series A round. The investment was led by Samved VC and Silicon Road Ventures, with participation from existing investors including Pentathlon Ventures, 100Unicorns, and Venture Catalysts. The funding reflects strong investor confidence in OneStack’s mission to modernise one of India’s most critical yet underserved banking segments.

Founded in 2019 by Amit Kapoor and Vishal Gupta, OneStack was built with a clear objective — to enable cooperative banks and credit societies to adopt modern digital banking infrastructure without the complexity and cost associated with traditional systems. The startup operates on a SaaS-based model, offering technology solutions tailored to the operational and regulatory needs of cooperative banks.

Building Digital Infrastructure for Cooperative Banks

OneStack provides an integrated digital banking stack that includes mobile banking apps, UPI payments, QR-based transactions, BBPS services, SoundBox solutions, and core banking support. By bringing these offerings under a single platform, the startup helps cooperative banks streamline operations, enhance customer engagement, and meet evolving regulatory standards.

India’s cooperative banking sector plays a crucial role in providing financial access to semi-urban and rural populations. However, many cooperative banks still rely on outdated systems, limiting their ability to offer digital services that customers now expect. OneStack aims to bridge this technology gap by delivering scalable and affordable digital tools designed specifically for this segment.

Strong Growth and Expanding Footprint

Currently, OneStack works with more than 200 cooperative banks across multiple states. The company processes over ₹750 crore in annual UPI transaction value, showcasing strong adoption of its digital payment solutions. With the newly raised capital, OneStack plans to expand its network to around 500 cooperative banks over the next two years and cross ₹1,000 crore in UPI transaction volume in the near future.

The cooperative banking ecosystem in India includes over one lakh institutions managing assets worth several lakh crore rupees. As regulatory oversight increases and customer demand shifts toward digital banking, the need for technology-driven transformation has become unavoidable. OneStack positions itself as a long-term digital partner for these institutions.

Funding to Accelerate Product Development and Scale

The fresh funding will be used to strengthen OneStack’s technology platform, enhance core banking capabilities, and deepen payment and billing integrations. The startup also plans to expand into more states and invest in improving compliance, reporting, and security features.

According to the founders, cooperative banks today face increasing regulatory expectations while simultaneously needing to compete with commercial banks and fintech apps. OneStack’s modular and regulation-ready platform helps these banks remain compliant while offering modern digital services to their customers.

Investors backing the company believe OneStack’s deep understanding of cooperative banking workflows, combined with its focused product approach, gives it a strong edge in the fintech ecosystem.

With total funding estimated at over $4 million, OneStack continues to emerge as a key player driving digital transformation at the grassroots level, contributing to financial inclusion and strengthening India’s cooperative banking framework in the digital era.
