Zolve is a Bangalore-headquartered neobanking startup focused on helping immigrants gain access to U.S. financial services. Its core product is a credit card, complemented by a local bank account and debit card, with Zolve underwriting risk so partner banks can offer services without security deposits. The startup rolled out its credit card to 2,000 customers and has a waiting list exceeding 70,000, with customers widely using the product and paying on time. Customers have deposited about $2 million into Zolve accounts and are often using them as primary bank accounts.

The startup underwrites the risk for partner banks, enabling customers to open accounts and obtain services as if they were banking with a national institution. Beyond basic banking, Zolve lets customers in India buy U.S.-listed shares and purchase cryptocurrency from exchanges based in the U.S. or Europe. The company is headquartered in San Francisco and Bangalore and was founded by Raghunandan G, who previously started TaxiForSure. Zolve has amassed more than 5,000 customers and has revenue-sharing arrangements with its banking partners. Because it onboards customers in India while generating much of its revenue from U.S. partners, the company says it is already operating on a profitable model.

The award is intended to enable further development and clinical advancement of Neural Ice across additional indications. Sameer Sabir, CEO and co-founder, characterized the grant as a significant step toward bringing safer, non-addictive pain options to a broad array of patients.

Its lead therapeutic approach, Neural Ice™, is a single, safe, drug-free injectable designed to provide locally targeted, non-addictive, and comparatively long-lasting pain relief. The company plans to use new capital to initiate pivotal clinical studies in both chronic and acute pain indications.

Management says the firm intends to expand the Neural Ice platform beyond the knee to multiple pain indications with an ultra-long acting injectable nerve block. The company recently added Dr. Michael Fishman as Chief Medical Officer and appointed Reggie Groves to its board to support clinical and commercial efforts.
