Sketchbook

Sketchbook is a sketching, painting, and illustration software. The job it does: designing and building iOS and Android apps.

Who is it for? Mostly businesses launching or rebuilding an app. Related areas on their profile: Art. As a very small company team themselves (1 to 10 people), they tend to serve customers of a similar scale best. Small vendors mean quick answers and real influence on the roadmap, but check who covers support when someone is out.

Sketchbook is based in San Francisco, California. More on sketchbook.com.

Things worth asking about: portfolio quality, app store experience, and maintenance terms. A short pilot with your real data tells you more than any demo.
