The Methodology

Proprietary Business Safety Valves — Physics-grade rigor for business decisions

Mirror Analysis

A particle-physics approach to marketing attribution. Invented at eBay, this method collapsed last-click ROI myths and revealed true incremental value — saving over $100M.

Proven at eBay

Jackknife-Median Estimator

A robust statistical method for computing accurate medians over massive, partitioned datasets where traditional methods fail. Battle-tested at 500 petabyte scale.

Scalable SQL

Single Pane of Glass Blueprint

The executive command center design used at Optum during the Change Healthcare merger. Centralized Snowflake warehouse with unified AI/BI accountability.

Why Hire a Physicist for Business?

Business is noisy. Physics is precise.

I treat your marketing and operations like a high-energy physics experiment. Where others see chaos, I see signal buried in noise. Where others guess, I measure. Where others debate, I design experiments that prove causation.

The result? Decisions backed by the same rigor that discovered the Higgs boson — applied to your revenue, your customers, and your competitive advantage.

How Turning Off $100M of Ads Made Us Smarter

Internal models showed high ROI. The truth? A -63% return. We ran one of the largest marketing experiments in corporate history, turning off Google AdWords in 30% of U.S. markets to find the real answer.
