About the Company

Level 12 is development firm that specializes in building custom software for our customers. We manage the entire process including planning, managing, and building software exactly as the customer needs it.

We serve customers in diverse industries including: railroad, automotive, manufacturing, and retail payments.

We set ourselves apart by digging into the customer’s problem until we can own it and then delivering highly functional software that brings significant value to the customer’s organization. That may not sound unique, but the longer we do this, the more we encounter people who have been burned by bad development experiences with other firms. We look for long-term relationships with our customers and have some that go back over 12 years.

Behind the scenes, we are using software development best practices (including agile principles and automated testing) to ensure that the code we deliver is flexible, maintainable, and works well for the user for years to come.
