We raised $8 million to transform mobile onboarding experiences

Big news: We just closed an $8 million seed funding round led by Singular and Seedcamp!

With this support, we’re ready to introduce new mobile-first onboarding tools that make signing up (and staying secure) even smoother for users everywhere.

Why we started Prelude

Prelude was born in 2022 from our founders Matias and Quentin’s experience at Zenly. Back then, SMS verification was one of Zenly’s biggest expenses—and there was almost no transparency around costs. Even worse, about 30% of the budget was being lost to fraud! Existing providers just weren’t set up to protect against this, so Matias and Quentin thought, why not build something better?

That’s how Prelude came to be! Think of us as a “Skyscanner” for SMS verification: we route messages along the most efficient, cost-effective paths, keeping verification costs low and transparency high. Our clients save about 40% on their messaging costs, while boosting conversion rates on verification messages to 95%.

SMS verification is just the beginning

We know one of the toughest parts of growth is turning new users into loyal ones—and we’re tackling that problem head-on.

“We’re committed to tackling SMS fraud at its core and using our experience to go beyond just SMS verification,” says our CEO, Matias. “Our goal is to help customers master user onboarding, trust, and retention with a suite of mobile-first services designed for seamless user experiences.”

So, in addition to SMS verification, we’re building new tools to make the whole onboarding experience better, helping businesses retain trust with their users from that first “Welcome!” message onward.

Our investors get our mission, and we’re stoked to have Singular backing us. Henri Tilloy, Partner at Singular, put it perfectly: “Prelude is transforming phone verification and authentication. With just a single line of code, businesses can cut costs, improve fraud protection, and increase conversion rates.”

With this fresh funding, we’re going to continue streamlining and scaling our API to bring tangible results to our clients—all while keeping it simple and efficient for developers.

What’s next?

This funding isn’t just helping us grow our SMS verification solutions; we’re building out a full suite of APIs to make user onboarding as seamless, trustworthy, and efficient as possible.

From verifying users to onboarding them smoothly, our mission is to bring next-gen onboarding tools to every business looking to grow their user base securely and transparently. We’re committed to continually enhancing the quality of our service and customer support, while expanding our offerings to meet even more of our customers’ needs.

So stay tune for what’s ahead!
