Telerain

Telerain provides cloud call center software. Put simply, it is about designing and building iOS and Android apps.

Who is it for? Mostly businesses launching or rebuilding an app. Alongside the main category they mention Mobile Apps and Telecommunications. They are a small team, 11 to 50 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.

Telerain is based in Simi Valley, California. More on telerain.com.

Before you commit, look at portfolio quality, app store experience, and maintenance terms. A short pilot with your real data tells you more than any demo.
