Fonoster

Fonoster is a mobile app development company. Unified Communication & Telephony API. The job it does: designing and building iOS and Android apps.

The natural audience is businesses launching or rebuilding an app. They also list Telecommunications, so expect those to show up in the feature set. 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.

Fonoster is based in Cameron, North Carolina and founded in 2015. Their site is fonoster.com.
