Use Cases

Who This Is For

Real scenarios from NBFC and fintech teams we work with.

NBFC Lending App

You are building an NBFC lending app and need PAN verification and Aadhaar eKYC before onboarding borrowers. Viantha integrates Karza or Signzy into your existing Spring Boot backend — typically in 5–7 working days. You get working API endpoints, documentation, and test cases.

B2B Lending & GST Underwriting

You have a B2B lending product and need GST verification to assess business health before sanctioning a loan. Viantha wires up GSTIN lookup, return filing history, and turnover estimation — so your underwriting engine has the data it needs automatically.

RBI NBFC Licence — Compliant LOS

You are applying for an RBI NBFC licence and your technology stack needs a compliant Loan Origination System. Viantha builds or integrates a full LOS — application capture, KYC, credit bureau pull, rule-based decisioning, e-sign, and disbursal. Delivered in 6–10 weeks.
