Prelude is a Paris-based onboarding and trust infrastructure platform that helps companies verify and protect users across their entire lifecycle by combining telecom data, behavioural signals, and machine learning. Founded in 2022 by former Zenly engineers Matias Berny and Quentin Le Bras, the company was born out of first-hand experience losing ~30% of SMS verification budgets to fraud. The platform unifies phone verification, fraud detection, device intelligence, and authentication into a single API, helping clients cut verification costs by 40% while improving conversion rates. Prelude has grown revenue and customers 6x year-over-year, serving companies like BeReal, Suno, Voodoo, and Sunday, and counts over 100 million protected user accounts. In May 2026, Prelude raised a $20M Series A led by 20VC, bringing total funding to $27M, and simultaneously launched two new products: Auth API and Intel API.
