A product you can build on
We’re more than developers. We’re Startup Architects. We take ownership of the full tech stack, building you a high-quality product that meets your needs now and can grow and scale with you in the future.
Instead of locking you into a scoped agreement, we work with you month-to-month for as little or as long as you like. Our process is fast, agile and ready to pivot as needed...just like your startup.
We don’t do SOWs and estimates. Instead, we charge a flat monthly rate, and we aren’t afraid to share it.See our pricing.
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.

"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
