## About

Based in Paris, France, and founded in 2022 by Matias Berny and Quentin Le Bras, Ding SAS, trading under the name Prelude operates as a software company that focuses on providing a verification API that supports user authentication through SMS messages. In May 2026, Prelude raised EUR 17.2 million in series A funding led by 20VC, with participation from Deel, Inc., La Française des Jeux (FDJ), Seedcamp, and Singular.

Prelude's core offering is an OTP (one-time password) and SMS verification API designed specifically for developers. This technology enables businesses to send verification messages at scale without incurring excessive costs or compromising on quality. Prelude's API integrates with over 20 global and local text-message providers. The service addresses critical use cases in user authentication and verification processes, enhancing security, reducing fraud, and improving user conversion rates. Notable clients leveraging Prelude's services include companies in various sectors such as tech, gaming, and social media, showcasing its versatility.

Prelude generates revenue primarily through a transaction-based model, where clients pay for SMS messages sent via its API. Clients access the service through subscription plans, with costs determined by the volume of messages and geographical routing options. For instance, pricing for SMS messages varies by country, with the US priced at EUR 0.0012 per message and Japan at EUR 0.0163, reflecting a tiered structure that incentivizes higher volumes.

The company will use the May 2026 17.2 million EUR funding to scale its trust infrastructure through deeper telecom partnerships, expand its API coverage across Europe, further invest in machine-learning-based fraud detection, and expand its team across engineering, partnerships, and customer success.
