Check reachability, line type, and portability before sending, so verification spend is not wasted on invalid or high-risk numbers.

Prelude positions itself as a trust layer between a product's signups and its business. At its core is an OTP verification API that developers call to send one-time codes across SMS, WhatsApp, RCS, Voice, and Email in more than 230 regions. A routing engine picks the cheapest and most reliable channel per attempt, and message costs are passed through at carrier rates without markup, with revenue coming from the verification fee instead.
The platform has since grown into a broader onboarding suite. Alongside Verify there is Auth for a full authentication stack, Watch for pre-KYC risk scoring that blocks fake accounts and card-testing before they cost money, Intel for number intelligence such as reachability and line type, and Notify for transactional messaging. Device, network, carrier, and behavioral signals feed a single onboarding decision, and the company reports figures such as 95% verification success, 99% fraud reduction, and roughly 30% lower costs than previous providers.
Prelude is aimed at engineering and risk teams in fintech, mobility, marketplaces, and other consumer apps. Integration is a few lines of code with SDKs for Node.js, Go, Python, Kotlin/Java, and Ruby, plus a dashboard for OTP routing, message templates, and delivery insights. Security and compliance include SOC 2 Type II, ISO 27001, and GDPR readiness, and the company notes that it is built in Europe and is a GSMA member.
Drop in a few lines of code to send and check OTPs across multiple channels without building carrier integrations yourself.
Use signal-based risk scoring to block abusive traffic and fraudulent registrations while legitimate users pass through untouched.
Combine OTP verification with pre-KYC scoring to keep onboarding friction low while meeting identity and compliance expectations.
Route each attempt through the cheapest reliable channel and monitor delivery insights to reduce spend without losing conversion.
