Infra Cost
India's first API-first Lending Against Securities platform
The Challenge

Lark Finserv needed India's first API-first LAS infrastructure to let wealth-tech platforms embed credit directly into their apps — with real-time loan processing, multi-lender integration, and full compliance, all without a large in-house engineering team.

Business Impact
  • Platform live in 12 weeks — enabled September 2025 public launch
  • Multiple lending partners onboarded within 30 days
  • API response under 200ms — tier-1 fintech competitive
  • Zero compliance incidents since launch
What Vikgol Built
  • Full-stack LAS platform — borrower portal, partner dashboard, admin panel
  • Multi-lender API gateway with real-time underwriting & disbursement
  • RuPay & mutual fund integration for securities verification
  • Compliance module — KYC, e-NACH, e-sign workflow automation
Client Testimonial

Vikgol understood the complexity of fintech infrastructure from day one. They didn't just write code — they thought through compliance, partner integrations, and scale before writing a single line.

  • Transaction time reduced by 2× vs previous system
