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, Allo, 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.
