About the company

Prelude is redefining how companies authenticate and onboard users: its flagship product sends OTP codes with the best price-to-conversion ratio on the market, dynamically selecting the best channel in real time (SMS, WhatsApp and more) while blocking spam and fraud that legacy providers miss. Founded in 2022 by former Zenly team members, the Paris-based team of about 60 already serves fast-growing companies across Europe and is expanding into the US.
