Mavani Solution engineers bank-grade financial applications for startups, lenders, and wealth management firms globally. We build digital wallets, BNPL platforms, peer-to-peer lending apps, and investment dashboards with end-to-end encryption, biometric authentication, and compliance-ready architecture. Our FinTech apps support KYC/AML automation, open banking API integration, and real-time transaction monitoring built to meet regulatory requirements across multiple jurisdictions including GDPR, PCI DSS, FCA, and ASIC. A typical FinTech MVP takes 12 to 16 weeks from kickoff to launch, priced on fixed milestones with no hourly billing.
