The Logo
What do you see when you look at a question mark?
Four shapes from process engineering, arranged as a control loop that forms a question mark. Not decoration — a diagram compressed into a brand mark.
The P&ID Origin
P&IDs (Process & Instrumentation Diagrams) are how engineers draw factories. Every valve, sensor, pump, and feedback loop — made visible on paper before a single pipe gets welded. If you can picture the system, you can build it.
The logo uses four P&ID symbols:
| Shape | P&ID Element | Function | Tight Five |
|---|---|---|---|
| Trapezoid (top-left) | Hopper | Captures raw material | Why does this matter? |
| Triangle (bottom-left) | Pump | Drives flow through the system | What do you control? |
| Circle (bottom-right) | Gauge | Measures what's happening | How do you know it's working? |
| Curve (top-right) | Controller | Reads the gauge, adjusts the system | What do you see others don't? |
The filter is implied between hopper and pump — principles that determine what passes through. That's the fifth element: What truths guide you?
Why a Question Mark
The controller's job is to question. It reads the gauge, compares the measurement to a setpoint, and asks: is this where we should be? If not, it adjusts. Constantly. Automatically.
The four shapes form a question mark because the entire system IS a question. The loop never settles — it keeps asking, measuring, adjusting. That's what makes it a feedback loop rather than a one-shot process.
HOPPER → FILTER → PUMP → GAUGE → CONTROLLER

In a dairy factory, this loop controls everything — the flow of milk through pasteurization, the speed of the pump, the temperature at the heat exchanger. The gauge reads reality. The controller compares it to the target. The pump adjusts.
In a mind, the same architecture applies. The hopper captures intention. Principles filter noise. Action drives progress. Measurement shows what happened. And perspective — the controller — asks what to do differently.
Two Loops
The same four stations run at two scales:
| Station | Inner Loop (Mindset) | Outer Loop (Environment) |
|---|---|---|
| Hopper | What do I care about? | What opportunities exist? |
| Filter | What principles guide me? | What standards apply? |
| Pump | What will I do? | What will I build? |
| Gauge | Did it work? | What do the numbers say? |
| Controller | What am I not seeing? | What's changing? |
When both loops run clean, you experience flow. The logo is a picture of that architecture.
