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 euros from Lightspeed, EMBLEM, and 30+ top operators.
Our team is based in Paris, Buenos Aires, and soon Miami.
What will you do
End-to-end ownership: Lead UX/UI design from concept to production — flows, visuals, prototypes, and handoff.
Consumer-grade craft: Deliver beautiful, intuitive experiences that SMBs actually love to use.
Flow simplification: Turn complex workflows into simple, mobile-first journeys.
Cross-functional delivery: Work closely with product, engineering, and growth to ship fast and iterate.
What you’ll be working on
Running competitor research and user interviews to shape product direction.
Designing onboarding and retention flows, iterating based on data and feedback.
Building and evolving our design system across multiple apps.
Collaborating on branding and visual identity alongside growth and product.
Prototyping new features and validating them quickly with real users.
