American Founder Builds Accessibility App Success in France

Olivier Jeannel knew exactly what problem needed solving because he lived it every day.

Diagnosed with severe hearing loss at age two, the French-American entrepreneur watched others struggle with something most people take for granted: making phone calls. In 2014, he launched Rogervoice, an app that provides real-time captioning and text-to-speech conversion for phone calls, turning an everyday challenge into a growing business.

Today, Rogervoice operates in 52 countries with 80 employees. The app has raised $2.5 million and built partnerships with major French carriers like Orange and SFR, plus government agencies.

What makes Jeannel's story remarkable isn't just the technology. It's where he chose to build it.

Despite America's reputation as startup paradise, Jeannel launched Rogervoice in France. The timing couldn't have been better: France's first accelerator programs were just starting, and the small circle of entrepreneurs welcomed him immediately.

France also had something America didn't: a massive gap in accessibility services. While US disability laws had already driven creation of similar tools, France desperately needed solutions. When France passed the Digital Republic Act requiring phone carriers to serve deaf and hard-of-hearing customers, Jeannel was already there with the answer.

The French system supported him in unexpected ways. Unemployment benefits gave him 18 months of financial runway after leaving his job at Orange. His first fundraising round took 12 months but landed 95 business angels who believed in the mission and kept investing year after year.

The Ripple Effect

Rogervoice now does far more than caption calls. Users can block unwanted callers, receive transcribed voicemails, and access sign language interpreting for video calls. Americans with disabilities get free calls through FCC certification, making international communication between the US and France truly accessible.

While many French startups relocate to chase American capital, Rogervoice stayed rooted in France. The company recently expanded US operations to meet growing demand, but its headquarters remains in Paris, where the social mission started.

Jeannel's choice to build in France instead of Silicon Valley shows how the right market timing and supportive infrastructure can trump traditional startup wisdom. France went from having almost nothing in telephone accessibility to becoming Rogervoice's biggest market, and the company helped fill that gap while growing into a global service.

For the millions who struggle with phone calls, Rogervoice proves that solving real problems creates lasting success.
