BuildKeeper

BuildKeeper is the easiest way to run the contractor business. In practice that means designing and building iOS and Android apps.

It makes the most sense for businesses launching or rebuilding an app. Alongside the main category they mention Cloud Data Services, Mobile Apps and Real Time. They are a very small team, 1 to 10 people, which usually shapes who they work with. You will probably talk to the people who build it, which is great until you need 24/7 support.

BuildKeeper is based in Santa Barbara, California. More on buildkeeper.com.

Things worth asking about: portfolio quality, app store experience, and maintenance terms. Get the renewal terms in writing before the first invoice.

If you have worked with BuildKeeper, tell the next buyer what you paid and what surprised you. That is the part of this page we cannot write.
