About Prelude
Prelude is redefining how companies onboard and authenticate users in a world where trust, speed, and conversion matter more than ever.
We help businesses verify users with less friction, higher security, and better economics, turning authentication from a cost center into a growth lever. Our flagship product enables companies to send OTP codes with the best price to conversion ratio on the market, dynamically selecting the most effective delivery channel in real time, from optimized SMS routing to messaging apps like WhatsApp. At the same time, Prelude actively blocks spam and fraud patterns that legacy providers routinely miss, protecting margins and user experience.
Founded in 2022 and backed by leading venture capital firms, Prelude has quickly reached strong product market fit and healthy financials, serving fast growing companies across Europe and expanding into the US market. Authentication is only the starting point.
With an ambitious roadmap and a pipeline of market defining products, we are building the platform for trust at scale, empowering companies to onboard users seamlessly, fight fraud intelligently, and grow globally with confidence.
Our team
Prelude was founded by former Zenly team members who experienced firsthand the limitations of existing authentication solutions. While building products used by millions, we saw how SMS authentication had become expensive, unreliable, and vulnerable to spam and fraud, ultimately leading to the creation of Prelude.
Today, we are a team of 40 and growing, based in Paris, building products that power secure and high-performance user onboarding for companies across Europe and the US. We believe small, highly skilled teams outperform large, fragmented organizations, and we are intentional about staying focused on impact, quality, and speed.
We operate with a flat organizational structure and value in-person collaboration, which helps ideas move faster, decisions stay grounded, and teams take full ownership of what they build.
Our values shape how we work every day:
Care
We care deeply about our customers, our teammates, and the quality and reliability of what we ship.
Bias for Action
We move fast, test in the real world, and iterate quickly rather than over-optimizing in theory.
Ownership
We take responsibility end to end, from identifying problems to delivering outcomes and learning from results.
These values underpin the company we are today and the team we are building for the future.
