SquareOne Mail

SquareOne Mail is an email service assistant that builds a mobile application for presorting users' emails into a dashboard. In practice that means designing and building iOS and Android apps.

Who is it for? Mostly businesses launching or rebuilding an app. Alongside the main category they mention Email, iOS and Web Development. As a small company team themselves (11 to 50 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.

SquareOne Mail is based in San Francisco, California. You can read more at squareonemail.com.

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