Pengram

Pengram provides indoor navigation to guide anyone in large buildings. Put simply, it is about designing and building iOS and Android apps.

Who is it for? Mostly businesses launching or rebuilding an app. Related areas on their profile: Augmented Reality, Computer Vision and iOS. 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.

Pengram is based in Berkeley, California. Their site is pengramar.com.

Things worth asking about: portfolio quality, app store experience, and maintenance terms. A short pilot with your real data tells you more than any demo.

If you have worked with Pengram, tell the next buyer what you paid and what surprised you. That is the part of this page we cannot write.
