About

Meet Ken. The Offline AI Expert.

Fifty years of building. Fifteen years in the Fortune 500.

"I never stopped working with the technology. While other executives moved into pure management, I kept coding, kept experimenting, and kept building."

A career that points in one direction: offline.

Ken Rheingans has been building technology since 1976. He has written real-time firmware at a major Los Angeles aerospace and defense contractor, co-founded technology startups, and led software teams of over 100 engineers. He rose to VP Global Information Services at a $20B Fortune 500 company operating in 70 countries.

Look closely at that career and a pattern emerges. Real-time firmware that had to run with zero network dependency. Defense systems where data could not leave the perimeter. Offline and locally controlled was never a niche for Ken. It was simply how serious systems were built.

When generative AI arrived, the rest of the industry rushed to the cloud. Ken did the opposite. He brought it home.

The four pillars, lived

What makes Burritt Center the Offline AI Experts is not a tagline. It's the work.

Offline AI

Every Burritt Center product runs without an internet connection. No cloud fallback, no "phone home," no degraded mode. Ken proves this on real hardware every day.

AI Privacy

Runs with no internet connection. No accounts, no tracking, no cloud transcripts. Ken spent years in IT consulting helping companies design and ship software that worked offline by default, and brings that same discipline to every Burritt Center product.

Local LLM Performance

Quantization, model selection, inference tuning, and hardware fit. Ken has personally benchmarked dozens of open-source models across CPU, consumer GPU, and edge silicon to find what actually works at each price point.

Custom Offline AI Builds

Under the Executive Retainer, Ken helps companies design and ship their own offline AI products, internal tools, and fully offline workflows. The same craftsmanship that built the Burritt Center product line, applied to your problem.

The Burritt Center

An AI lab above a garage. A 135-year-old barn. A pond. A name from a one-room schoolhouse.

How it started

The Burritt Center was founded in 2017 from a 42-acre former dairy farm in southeast Wisconsin, featuring a 135-year-old barn. It is named after Burritt Center School, the one-room schoolhouse Ken attended for first, second, and third grade in rural northern Illinois. It was one of the last operating one-room schoolhouses in the state. One teacher, no internet, and everything you needed to learn in a single room. The original offline classroom, and a fitting namesake for the Offline AI Experts.

The lab

During the COVID lockdown, Ken built an AI lab above his garage and started running AI on everything from low-power single-board computers to multi-GPU workstations. Every product ships only after it runs reliably across multiple classes of hardware.

What comes out of the lab

The lab is where every Burritt Center product is tested, broken, and rebuilt until it runs reliably offline. Each product pairs carefully chosen models with curated libraries, then gets stress-tested against the conditions it was built for: weeks without internet.

The philosophy

Be practical. Be honest. Prove it works without the cloud. Executives and product teams deserve an advisor who has actually built what they are being asked to advise on, not someone who presents about AI but never ships it.

Career timeline

Five decades of building. One thread running through it.

From assembly code in 1976 to running modern LLMs on his own hardware in 2026. The work has always been about owning what you build and running it on infrastructure you control.

Why this matters

Offline isn't a feature here. It's the entire thesis.

The lab proved that real, useful AI does not require an expensive cloud bill, a recurring subscription, or sending your data to someone else's servers. That conviction is now the entire focus of the company: offline products you can buy, and consulting engagements that help your team adopt AI offline or build their own offline AI products. Cloud AI is convenient. Offline AI is sovereign.
