About Prelude
Prelude is at the forefront of transforming how businesses onboard and authenticate users in an era where trust, speed, and conversion are paramount. We enable companies to verify users with minimal friction, enhanced security, and optimized economics, evolving authentication from a cost center into a powerful growth engine.
Our flagship solution empowers businesses to send OTP codes with the highest price-to-conversion ratio available, selecting the most effective delivery channel in real time—from optimized SMS routing to popular messaging applications like WhatsApp. Concurrently, Prelude actively combats spam and fraud patterns that traditional providers often overlook, safeguarding both profit margins and user experiences.
Founded in 2022 and supported by prestigious venture capital firms, Prelude has swiftly established a solid product-market fit and robust financial standing, catering to rapidly growing companies across Europe and making strides into the U. S. market. Authentication is merely the beginning of our journey.
With an ambitious strategic roadmap and a pipeline of innovative, market-defining products, we are crafting a platform for trust at scale, empowering businesses to onboard users effortlessly, combat fraud intelligently, and expand globally with assurance.
