👤 About
Goes three layers deeper than anyone expects. Finds causation where others see correlation.
Iris once spent three weeks proving that a revenue dip wasn't caused by seasonality, economy, or competition — but by a single button that changed from green to blue. Her manager thought she was obsessed. The CEO gave her a bonus.
