Prelude: How This Startup Aims to Revolutionize SMS Verification

At the Web Summit, Prelude, a leader in SMS fraud prevention, announced an $8 million funding round backed by Singular and Seedcamp to boost its global expansion and mobile integration innovation.
The Next Step in SMS Verification
Prelude, heralded for crafting a fraud-resistant SMS verification API, announced at the Web Summit a successful $8 million funding round. Supported robustly by Singular and Seedcamp, these funds will fuel their global expansion and the development of new mobile-focused integration services.
Birth of an Innovative Solution
Founded in 2022 by Matias Berny and Quentin Le Bras, Prelude was inspired by their stint at Zenly, which Snap acquired in 2017. The founders realized the high cost and substantial budget losses due to SMS verification fraud. In response, Prelude engineered a solution providing cheaper messaging pathways between businesses and mobile network operators, significantly cutting down SMS fraud.
Transforming SMS Verification
“We are committed to combating SMS fraud at its root and to transcend traditional SMS verification.” stated Matias Berny, founder and CEO of Prelude. Their solution has slashed verification costs by 40% and achieved a 95% conversion rate on verification messages.
Henri Tilloy, a partner at Singular, praised their approach: “Prelude is revolutionizing the phone verification and authentication space. Their user-friendly solution delivers immediate and tangible value, significantly lowering costs, enhancing fraud protection, and boosting conversion rates—all with just a single line of code.“
Prelude: A Transformed User Experience
This French startup has safeguarded over 100 million user accounts, collaborating with major global companies such as BeReal, Locket, Alma, and Bitstack. Arnaud Lemaire, CTO of Sunday, a global payment service for restaurants, shared his positive experience: “With Prelude, we’ve completely transformed our messaging strategy. Now, we send OTPs worldwide effortlessly, with complete visibility on deliverability and conversion rates.“
Prelude plans to use this funding to innovate and expand their platform, aiming to become a pioneer in mobile integration with multiple APIs to help clients verify, onboard, and build trust with new users as they enter their mobile applications.
