Teleparty

Teleparty is a free Microsoft Edge and Google Chrome Extension. In practice that means designing and building iOS and Android apps.

It makes the most sense for businesses launching or rebuilding an app. Alongside the main category they mention Media and Entertainment and Video Streaming. As a mid-sized company team themselves (51 to 200 people), they tend to serve customers of a similar scale best.

Teleparty is based in San Francisco, California. Their site is teleparty.com.

Things worth asking about: portfolio quality, app store experience, and maintenance terms. Ask for a trial on your own data, not a canned demo.
