Like the roads in Montreal this time of year, our new website is under construction

But don't worry - we're still open for business! We help startups increase their chances of success with scalable, high-quality apps, transparent pricing and a startup-friendly process.


A product you can build on.

We take ownership of the full tech stack, building you a high-quality product that's easy to scale and maintain.


Startup-friendly process.

Instead of locking you into a scoped agreement, we work with you month-to-month for as little or as long as you like.


Money-back guarantee.

Try us out risk-free for seven days. If you're unhappy with our work or process, we'll give you a full refund. Yep, really.

Loved by YC-backed startups

"At Expo we have worked with App & Flow to develop a number of features into our product and it was always a pleasure to collaborate with Charles and the rest of the team! We frequently recommend them to folks that come to us looking for help with their React or React Native apps."

— Brent Vatne, Software Developer at Expo
