Bengaluru-based B2B fintech SaaS startup FinBox has raised $40 Mn (around INR 350 Cr) in its Series B round led by WestBridge Capital to launch new products and enhance its current offerings.

Existing backers such as A91 Partners and Aditya Birla Ventures also doubled down on their investment in the round.

The startup said in a statement that the fresh capital will accelerate tech investments, international expansion, and product growth, with a focus on scaling FinBox's AI-native lending platforms (Sentinel BRE, Prism), enhancing its risk management APIs (BankConnect, DeviceConnect, KYC), and developing agentic AI workflows along with a fraud intelligence suite.

Of the $40 Mn, $35 Mn was raised as primary capital, while $5 Mn came from secondary share sale by early angel investors.

Founded in 2017 by Rajat Deshpande, Anant Deshpande, Nikhil Bhawsinka, and Srijan Nagar, FinBox offers B2B credit infrastructure and risk intelligence solutions for banks, NBFCs, and fintechs. Its offerings span the entire digital lending lifecycle, from powering digital loan origination and underwriting to fraud detection and embedded lending.

Its products cover multiple categories, including end-to-end infrastructure to build, launch, and scale digital credit products, identity verification, and risk management tools (AI-powered solutions to assess credit risk and enable smarter lending decisions).

The startup counts lenders such as HDFC Bank, Kotak Mahindra Bank, Poonawalla Fincorp, Aditya Birla Capital, Muthoot Fincorp, and Tata Capital among its customers.

Prior to this funding, FinBox raised $15 Mn (INR 115 Cr) in 2022, with participation from A91 Partners, Aditya Birla Ventures, Flipkart Ventures, and Arali Ventures.

While the startup is yet to file its financial statements for FY25, its revenue grew 47% to INR 53.24 Cr in FY24 from INR 36.20 Cr in the previous year. Net loss widened to INR 33.60 Cr from INR 23.09 Cr in FY23.
