Cornerstone

Cornerstone is a software development firm that delivers secure software systems and components. Put simply, it is about building software for you when nothing off the shelf fits.

It makes the most sense for companies with a specific process to automate. Related areas on their profile: Hardware and Software Engineering. 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.

Cornerstone is based in Morgantown, Pennsylvania and around since 1989. Their site is csdisoftware.com.

Things worth asking about: portfolio relevance, who owns the code, and how they handle changes. Get the renewal terms in writing before the first invoice.
