Prelude in a snapshot
Solving real problems
We built Zenly from zero to tens of millions of users before Snap acquired it. Authentication was a nightmare for us and for our friends in other companies - we started Prelude to fix it.
Growing fast, moving fast
Our revenue and customer count grew 6x across 2025
Trusted by loved apps already
You might have already had a message from us. BeReal, Sunday, Suno and Voodoo all switched to Prelude because SMS was unpredictable and expensive.
$27M raised
Series A led by 20VC, with Singular, Seedcamp, Deel, and FDJ United Ventures.
International team
We’re 25+ nationalities and counting, bringing diverse experience from start-ups and scale-ups (Twilio, Pleo, Stripe, Afterpay, Okta). We work in English.
Paris office
Most of our roles work from our Paris HQ at least 3 days a week. We’re very central in the 10th arr.
How we work
Ownership
You own the problem, not just the task. If a customer has an issue at 2am, you want to know about it. You write the postmortem and ship the fix.
Care
A failed OTP blocks a real person from their account. We care about users we have never met. We fix things before customers notice.
Bias for action
Slow is expensive. We ship, learn, and fix. A working prototype beats a perfect proposal every time.
Impact-driven
We work on things that matter. Authentication is how hundreds of millions of people prove who they are every day. Getting it right is worth the effort.
