TerraStride

TerraStride designs and produces mapping software for high-value niche markets. 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 Mapping Services and Mobile Apps. They are a small team, 11 to 50 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.

TerraStride is based in Columbia, South Carolina and around since 2012. More on terrastride.com.
