Prelude Tech Stack

SMS and OTP verification APIs for developers

Software Development Paris 11–50 employees Privately Held

Prelude operates an SMS and OTP verification infrastructure layer for developer-first onboarding and authentication. The company is sales-led—14 of 24 open roles are sales-focused—while simultaneously building out anti-fraud detection and a distributed system on AWS. The pain-point pattern (spam/fraud vulnerability, unreliable SMS delivery, cost management) suggests Prelude is competing on reliability and price rather than feature breadth, and the project list shows concurrent investment in GTM enablement and the next API version.
