Vyng

Vyng has built a next-generation phone call platform to start better conversations with friends and better interactions with businesses. In practice that means designing and building iOS and Android apps.

The natural audience is businesses launching or rebuilding an app. Related areas on their profile: Digital Entertainment and Video. 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.

Vyng is based in Venice, California. More on vyng.me.

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.
