PROTOIO Inc

PROTOIO INC is the software company behind Proto.io and Overflow, the productivity tools that help teams build better products. The job it does: designing and building iOS and Android apps.

Who is it for? Mostly businesses launching or rebuilding an app. Alongside the main category they mention Android, iOS and Mobile. As a small company team themselves (11 to 50 people), they tend to serve customers of a similar scale best. You will probably talk to the people who build it, which is great until you need 24/7 support.

PROTOIO Inc is based in San Francisco, California and founded in 2011. Their site is protoioinc.com.
