Customer Success Intern

Prelude is on a mission to transform how companies onboard and authenticate users. We help businesses verify their users with greater efficiency, less friction, and stronger security — ultimately increasing conversion rates and reducing costs.

Our flagship product focuses on authentication, enabling companies to send OTP codes with the best price-to-conversion ratio available. We do this by dynamically selecting the most effective delivery channel (e.g. SMS via the optimal carrier vs. WhatsApp), while actively blocking costly spam and fraud attempts that traditional providers often miss.

Founded just two years ago, Prelude has already achieved healthy financials and strong product-market fit. But authentication is only the beginning. With a pipeline of bold, market-defining ideas, we're building the platform for trust at scale — and we're excited to shape the future of onboarding and user verification with you.

The Prelude team started with four former Zenly team members, a social network acquired by Snapchat in 2017. We created Prelude in response to a problem we had there: the current SMS authentication offering is too expensive, of poor quality and offers little to no protection against spam. We believe that having a small team of committed and skilled people with a flat hierarchical organization is the best way to build a tech company. It forces us to focus on what matters and only on what matters: delivering value to our customers. We also believe that at our current stage, we need to be face-to-face in our offices in Opera, so that ideas can flow freely and collaboration is spontaneous.

As a Customer Success Intern, you'll play a key role in ensuring our customers have an exceptional experience from their very first interaction onward.
