About Clotfelter Data & Design

A Chicago-area software practice focused on system architecture.

The firm was founded on a recurring observation: good ideas fail quietly when the underlying structure isn't sound. Rushed implementations, unnecessary tooling, and unclear data models create systems that work briefly and then resist change.

The work traces back to a personal project called ShuffleArchive, an experiment driven by curiosity. A system to simulate a deck of cards being shuffled once per second, every second of the day. 86,400 shuffles, built to explore probability, randomness, and long-term distribution patterns. It wasn't built for a client. It was built to understand something deeply.

After sharing it with a colleague, the response wasn't theoretical. It was practical. That conversation led to spatial database queries, which led to GIS systems, structured data workflows, document automation, AI-assisted processing, and eventually custom application builds and API integrations across industries.

The throughline has never been trend-chasing. It's been structure.

The Approach

Every engagement begins the same way: start with the data model, define the constraints, and design the system so it can withstand change.

A Message from
Keith Clotfelter
Founder

Clotfelter Data & Design grew out of a simple belief I've held for most of my career. When someone asked if something could be built, reported on, or understood in a new way, my answer was almost always the same: “If we have the data, we can build the insight.”

More often than not, the real challenge in software isn't the interface or the tooling, it's the structure of the data underneath. When the data model is sound, systems become flexible, reports become possible, and good ideas can actually work in practice.

That belief is how I genuinely plan and approach every project. I don't take shortcuts with systems that people will rely on. At Clotfelter Data and Design, we stand behind our product and Integrity is the backbone behind our work.

Because of that, I take on a limited number of projects at a time. Good systems require attention, not volume. When we work together, you are getting careful thinking, honest communication, and work that is built to last.

“If we have the data, we can build the insight.”
