Per Diem Plus, LLC

Per Diem Plus® is a mobile app that applies IRS-established Special Transportation Industry per diem rules for travel in the U.S and Canada. 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 Automotive, Logistics, Mobile and Mobile Apps. As a very small company team themselves (1 to 10 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.

Per Diem Plus, LLC is based in St Louis, Missouri. More on perdiemplus.com.
