FinBox, a credit infrastructure startup, has raised $40 million in its Series B funding round led by WestBridge Capital. 

The funding round also saw participation from existing investors A91 Partners and Aditya Birla Ventures. The investment deal also included $5 million in secondary transactions to provide partial exits to early investors. Flipkart was among the company's early backers.

The Bengaluru-based startup will use the fresh capital to accelerate product innovation, fuel international expansion, and deepen its AI-driven credit intelligence stack. The company plans to focus on strengthening its Sentinel BRE platform, Partnership Lending Stack (Prism), and fraud intelligence products.

The startup was founded by Rajat Deshpande, Anant Deshpande, Nikhil Bhawsinka, and Srijan Nagar in 2017. FinBox builds B2B credit infrastructure for banks, NBFCs, and fintechs through its modular platform that powers digital loan origination, underwriting, fraud detection, and embedded lending solutions.

The company currently serves over 130 large clients including HDFC Bank, Kotak Mahindra Bank, and Tata Capital, and has processed more than $9 billion in loan applications since inception.

Earlier in June 2022, the company raised $15 million in its Series A round which was led by A91 Partners.

The funding comes amid growing investor interest in credit infrastructure startups. FinBox competes with players like Perfios, Signzy, and Fibe in the B2B fintech space.
