The Physics of ROI

Stop Guessing.
Start Measuring like a Physicist.

Why 90% of Enterprise Data is Noise—and How to Find the Signal that Drives Revenue.

"In high-energy physics, we smash particles together to find the truth hidden in billions of collision events. In business, you smash marketing dollars against customer behavior—but most executives are just staring at the 'background noise' of vanity metrics.

I spent 6 years at CERN measuring electron size and 20 years at eBay, Google, and Optum measuring business value. I found that the methods are the same, but the rigor in business is missing. This Manifesto is my playbook for bringing scientific truth to your P&L."

What's Inside

The 3 Core Pillars

Not theory. Battle-tested frameworks from CERN, eBay, Google, and Optum.

Part 1

The Mirror Analysis

Causality vs. Correlation

How I used particle physics signal extraction to solve the "Multi-Touch Attribution" crisis at eBay—and why your marketing dashboard is probably lying to you.

Attribution
Part 2

The Courage of Zero

Incrementality

The $100 Million "Google Experiment." How we turned off paid search for 30% of the U.S. to prove that our 'ROI' was an illusion—and how to run this test in your business without getting fired.

Incrementality
Part 3

The Single Pane of Glass

Governance

How to build an "Executive Cockpit" that forces accountability (like we did at Optum) and prevents "Data Hide-and-Seek" during board meetings.

Governance

This Is For You If...

  • You're a CEO, CDO, or CFO who suspects your data teams are generating "reports" instead of revenue.
  • You're a Private Equity Operating Partner tired of portfolio companies with impressive dashboards and disappointing EBITDA.
  • You want profitable truths over comfortable lies.

This Is Not For You If...

  • You're looking for "growth hacks" or quick fixes.
  • You prefer comfortable narratives over uncomfortable data.
  • You're not in a position to change how your organization measures success.

If you want to install this level of rigor in your organization before Q1, I have limited spots open for a "Data Governance Diagnostic" this quarter.
