About Prelude
Prelude is revolutionizing the way businesses onboard and authenticate users in a landscape where trust, speed, and conversion are paramount.
Our solutions enable organizations to verify users with minimal friction, enhanced security, and cost-effectiveness, transforming authentication from a mere expense into a powerful growth catalyst. Our flagship product offers the most competitive price-to-conversion ratio for OTP codes, dynamically choosing the most efficient delivery method in real-time, from optimized SMS routing to popular messaging apps such as WhatsApp.
Founded in 2022 and backed by premier venture capital firms, Prelude has swiftly established a solid product-market fit and robust financial standing, catering to rapidly growing companies across Europe while also penetrating the US market. Authentication is just the beginning.
With a bold roadmap and an array of market-defining products in the pipeline, we are crafting a scalable platform for trust, empowering businesses to onboard users effortlessly, combat fraud intelligently, and expand globally with assurance.

About the Team
Our founders, previous members of the Zenly team, encountered firsthand the challenges of existing authentication solutions. While developing products used by millions, we recognized the escalating costs, unreliability, and vulnerability to spam and fraud in SMS authentication, which ultimately led to the inception of Prelude.
Today, we are a dedicated team of 40 and counting, based in Paris, creating products that enable secure and efficient user onboarding for businesses across Europe and the US. We believe that small, highly skilled teams can outperform larger, disjointed organizations, and we are committed to focusing on impact, quality, and speed.
We maintain a flat organizational structure and prioritize in-person collaboration, which accelerates the flow of ideas, grounds decision-making, and ensures teams take full ownership of their creations.
