Propane

The factory changed. The logistics system didn't. We're building it.

World map

Cursor, Claude Code, and Lovable changed how software gets built. The factory can produce more than ever. But the system that owns the entire process, from deciding what to build to getting that context to every team, has never been built. Engineering, marketing, sales, growth, customer success, all working from scattered tools and documents nobody reads. Productboard, Dovetail, Enterpret, Canny. All built for a world that no longer exists.

We are building what comes next. What Figma did for design, making it multiplayer and giving every team a seat at the table, we are doing for the entire product process. One system. Every team. All the context. The entire product process rebuilt for the agentic era.

How we work

Taste is a strategy

AI can build anything. Having a strong opinion about what good looks and feels like is the real differentiator.

Agency first

Anyone should be able to build, test, and iterate. We design for that, internally and in the product.

Knowledge compounds

Institutional knowledge is the moat of the next decade. We build systems that accumulate it over time.

Close to the customer

Behavior does not change without proximity. We go to where customers are, watch how they work, and build from there.

Lean is a philosophy

Not just headcount. The politics, the bloat, the operations. We keep it clean at every level.

Build for where it's going

We design for 2027, not today. AI is reshaping how work gets done. We want to be ahead of that, not catching up.
