The Indian fintech ecosystem continues to witness significant investments in infrastructure focused startups, with Zerodha’s investment arm Rainmatter recently backing Blostem, a B2B banking infrastructure platform. This pre-Series A funding round, while undisclosed in amount, underscores the growing recognition of banking infrastructure as a critical enabler for digital financial services in India.
Addressing a Critical Market Gap
Blostem was founded by Ravi Jain, Sandeep Garg, Uday Sharma, and Pankaj Pratap Singh with a clear mission: to simplify how fintech companies, brokers, payment platforms, and wealth tech firms integrate banking products into their offerings. Traditionally, companies seeking to offer banking services to their customers faced the arduous task of establishing separate integrations with each banking partner. This process was not only time consuming but also resource intensive, requiring significant technical expertise and ongoing maintenance.
The startup’s solution is elegantly straightforward – a single, unified API that provides plug and play access to multiple banking products. Through this infrastructure layer, partner platforms can launch fixed deposits, FD backed credit cards, and Credit on UPI without the complexity of managing multiple banking relationships and technical integrations. This approach dramatically reduces the time to market for financial products while minimizing operational overhead.
Building a Robust Banking Network
Blostem has made considerable progress in establishing its banking partner ecosystem. The company claims to have built connections with ten banks and non banking financial companies for its fixed deposit marketplace. Among these partners are several prominent institutions including Suryoday Small Finance Bank, Unity Small Finance Bank, Shivalik Small Finance Bank, Utkarsh Small Finance Bank, Bajaj Finance, Shriram Finance, and Mahindra Finance. This diverse network provides partner platforms with multiple options to offer competitive products to their end customers.
The startup’s client roster demonstrates strong market traction across various fintech segments. Blostem currently works with established platforms such as Mobikwik, Jupiter Money, Upstox, Aditya Birla Capital Digital, IRIS by KFin Technologies, Centricity Wealth, and GoldenPi. This diverse client base spanning digital payments, neobanking, stock broking, and wealth management validates the broad applicability of Blostem’s infrastructure solution.

Strategic Growth Plans
The fresh capital infusion will fuel Blostem’s expansion across multiple dimensions. Distribution expansion remains a key priority, with the company planning to launch its fixed deposit marketplace on Zerodha and other major platforms shortly. This integration with Zerodha, given its massive retail investor base, could significantly amplify Blostem’s reach and transaction volumes.
Beyond distribution, the startup intends to deepen its banking partnerships and broaden its product portfolio. The planned introduction of FD backed credit cards and Credit on UPI represents natural extensions of its current offerings, addressing evolving consumer credit needs. Additionally, Blostem will invest in building senior leadership capabilities across critical functions including technology, compliance, and partnerships areas essential for sustainable growth in the heavily regulated financial services sector.
The Broader Implications
Rainmatter’s investment in Blostem reflects a larger trend toward infrastructure consolidation in Indian fintech. As the market matures, there is increasing recognition that shared infrastructure solutions can drive efficiency and innovation across the ecosystem. By abstracting the complexity of banking integrations, platforms like Blostem enable fintech companies to focus on their core competencies whether that’s user experience, product innovation, or customer service, rather than backend infrastructure.
This investment also highlights the continued confidence in India’s digital banking transformation, where infrastructure providers play an increasingly vital role in democratizing access to financial services.
