Invertical

Invertical is a software agency that builds private social networks, mobile apps, SaasS, and e-commerce sites. The job it does: 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 E-Commerce and Mobile Apps. They are a very small team, 1 to 10 people, which usually shapes who they work with. Small vendors mean quick answers and real influence on the roadmap, but check who covers support when someone is out.

Invertical is based in Denver, Colorado. More on invertical.com.
