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

+15 million dolars

from Base10, Lightspeed, EMBLEM, and 30+ top operators.

Our team is based in

Paris, Buenos Aires

,

Miami
