create. capture. compose.
Technology should help creative people create AND capture what they do. That vision is 25 years old.
why "muselab"?
25 years ago, Muselab was going to be a rehearsal space. Every room wired to a central recording studio - so bands could rehearse AND record in the same session.
The insight: creative work happens in the moment. If you don't capture it as it happens, you lose it. Technology should serve that capture, not interrupt it.
That rehearsal space never got built. But the vision evolved. Today, a "Lab" is still that creative space - where builders create and their context gets captured. Different medium, same principle.

From captured context, synthesize new forms
context determines meaning
"The meaning of context depends on the context. It's turtles all the way down."
We believe in argucoding, not vibe coding. Real debate. Real arguments. Decisions captured with their reasoning. When you understand WHY something was built a certain way, you can evolve it intelligently - or know when to tear it down.

13 years building composable delivery. 11 years of CumulusCI. A rehearsal space that never got built. All pointing at the same insight.
Before founding Muselab, I spent 13 years at Salesforce.org building the systems that power composable delivery for the nonprofit and education sectors. I built and led the Release Engineering team responsible for shipping over 50 managed packages to hundreds of thousands of orgs.
The tools my team created — CumulusCI, Snowfakery, MetaCI, MetaDeploy, and Metecho — are still used across Salesforce and the broader ecosystem. They represent a decade of learning about what it takes to deliver software at scale on the platform.
