Prelude helps gambling and betting operators verify players and stop fraud at signup. Our phone verification and fraud prevention APIs catch fake accounts, bonus abuse, and multi-accounting before they cost you money, without adding friction to onboarding. Operators use Prelude to confirm a real phone number sits behind every new account, flag high-risk signups in real time, and cut SMS costs by routing OTP messages through the most reliable carrier for each country. The result is fewer fraudulent accounts, lower KYC and messaging costs, and a faster path from signup to first deposit. Prelude is used by consumer platforms across Europe that need to move fast without opening the door to fraud. We're based in Paris and built for teams shipping global products.
