Core banking APIs, KYC/AML compliance, payment rails, card network integration — one unified infrastructure layer that replaces seven vendors and gets you to production in 10–12 weeks.
Building core banking, compliance, and payment rails from scratch costs millions. Average time-to-market: 1.5–2 years. Opportunity loss exceeds $2M in missed revenue.
KYC/AML, PCI, data residency — one misstep triggers fines averaging $5M+ and license revocation. 73% of fintechs face compliance delays that kill fundraising momentum.
Managing 7+ separate vendors (processor, KYC provider, card network, FX, etc.) creates integration nightmares and hidden costs averaging $120K per year.
Nesvra replaces seven vendors with a single API-first backend — from core ledger to card network, compliance to settlement.
