Our story, our values.

Twelve years of captioning phone calls, so no conversation gets lost. This is who we are and why we build.

Rogervoice was founded in 2014 by Olivier Jeannel, soon joined by co-founder and CTO Bastien Le Rest.

Olivier was born in Los Angeles and has been deaf since age two. After graduating from UC Berkeley and Sciences Po Paris, he built a career in telecom. He was certain technology could give everyone the confidence to pick up the phone. So at 33, he built the app he needed himself and launched Rogervoice.

Twelve years later, Rogervoice is the global pioneer of real-time captioned calling, with more than 12 million calls captioned in 100+ languages. It’s an all-in-one, AI-powered, FCC-certified app. It turns phone calls and in-person conversations into secure, accurate captions and transcripts, in real time, on your terms. It’s free to eligible users and the #1-rated captioned calling app, averaged across iPhone and Android.* No human ever listens in. No ads. No data sold.

More than 100 people work to make this possible, bringing together vision, technology, design and execution. Our award-winning platform has set new standards and earned recognition from institutions worldwide.

* Highest average rating among FCC-certified captioned calling apps on the App Store and Google Play in the US as of October 2026

Our values

Trust

Gaining the trust of our customers and iterating on their feedback creates a reciprocal dynamic. We invest in a shared future built on collective capability.

Togetherness

We are united through a mission to reconnect and be better together, across skills, backgrounds and lived experiences.

Audacity

We ask what is possible instead of what is not. Because technology makes us bold and the human condition makes us humble, we question the status quo.

Our mission

Communication is a bedrock of humanity, uniting us through language and culture, across borders and generations.

Emails, chat, SMS and apps have revolutionised communication, yet phone calls remain an essential means of contact. For millions of people worldwide, understanding conversations on the phone isn’t easy, or even possible.

It’s why we’re proud of our mission to make phone calls possible according to each person’s needs. Wherever possible, we push the game to the next level, the level where society expects us to be, where our customers deserve us to be.
