"We needed to handle 500,000 OTPs in a single campaign window without a single failed delivery. Narvark handled it without breaking a sweat."

"PSD2 compliance was blocking our roadmap for months. Narvark gave us audit-ready SCA out of the box and we were live in under six weeks."

CTO · European Fintech Scale-up

"Switching from our legacy SMS provider saved us over £400K in year one. The WhatsApp fallback logic alone paid for itself within the first quarter."
