ABOUT THE MOBILE-FIRST COMPANY https://www.themobilefirstcompany.com
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 https://www.withallo.com/, 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 dolars from Lightspeed, EMBLEM, and 30+ top operators. Our team is based in Paris, Buenos Aires, Miami.
Drive the evolution of our backend technology, infrastructure, and AI capabilities to ensure high performance, scalability, and seamless integration for our mobile applications.
