About The Mobile-First Company
Most tools for small businesses weren't built for real operators.
They were built for employees in offices, not people running a business from their phone.
We're changing that.
We build mobile-first business software that feels like a consumer app, runs on AI, and spreads like a creator brand.
Our first product, Allô, gives you a second number on your phone, answers missed calls with AI, transcribes everything, and syncs it to your CRM.
Over 20,000 businesses use it every day.
Next up: expenses, invoicing, and more.
We've raised +5 million dollars from Lightspeed, EMBLEM, and 30+ top operators.
Our team is based in Paris, Buenos Aires, Miami.
Seniority level Mid-Senior level
Employment type Full-time
