Functum

Functum is a software consultancy firm that designs human‐centric and ergonomic applications. The job it does: designing and building iOS and Android apps.

Who is it for? Mostly businesses launching or rebuilding an app. Related areas on their profile: Consulting. As a very small company team themselves (1 to 10 people), they tend to serve customers of a similar scale best. Small vendors mean quick answers and real influence on the roadmap, but check who covers support when someone is out.

Functum is based in Detroit, Michigan. More on functum.com.
