Our Story

Four Decades of Building

We've spent over 40 years building software systems—from early enterprise applications to modern cloud-native architectures. We've seen technologies come and go, and we've learned what lasts.

When autonomous AI agents emerged as a viable technology, we saw an opportunity to apply decades of engineering discipline to a new frontier. Not to chase hype, but to build systems that actually work in production environments.

StencilWash exists because we believe autonomous systems should be built by people who understand security, reliability, and operations. Not by those who see AI as magic, but by engineers who know that every system eventually fails—and design for it.

Values

How We Work

Build to Last

We don't build disposable software. Every system is designed to be maintained, extended, and operated for years.

No Shortcuts

Security isn't optional. Testing isn't skipped. Documentation isn't deferred. We do the work right the first time.

Honest Assessment

We'll tell you if a project isn't a good fit. We'd rather lose a deal than deliver something that doesn't work.

Ownership

We build systems you can own. Documented, maintainable, and transferable. No vendor lock-in. No black boxes.

Philosophy

What We Believe

AI is a tool, not magic. It excels at specific tasks and fails at others. We use it where it creates value, not where it creates demos.

Security is foundational. It's not something you add later. It's how you design systems from the first line of code.

Complexity is the enemy. Simple systems are reliable systems. We fight complexity at every decision point.

Trust is earned. Through working software, clear communication, and honest assessment. Not through sales decks.
