About

justbuild is a design and build studio for founders. We take an idea or an early product and turn it into something people want to use and investors want to back. Design and engineering under one roof, shipped to production, built with you.

We work two ways. For a new idea, our fixed-price MVP sprint takes you from the first pixel to a running product with one or two core features in about four weeks, with scope and deadline locked before we start. For a product that already exists, our monthly Iterate retainer plugs in a senior product team that ships new features and refines the experience week after week, and redesigns vibe-coded products to a world-class standard.

So far we have worked on more than ten products, with a combined valuation above US$30M and 2.5 million users between them. We are based in Natal, Brazil, and work with founders anywhere.

If you are building something and want it designed and shipped properly, book a call and let's talk.
