Patrick Deglon — The Physicist Executive
Blue Fermion Advisory is currently not accepting new projects as I pursue an exciting new chapter.
I remain open to networking conversations and virtual coffee chats — feel free to reach out if you'd like to connect.
Proprietary Business Safety Valves — Physics-grade rigor for business decisions
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 eBayA robust statistical method for computing accurate medians over massive, partitioned datasets where traditional methods fail. Battle-tested at 500 petabyte scale.
Scalable SQLThe executive command center design used at Optum during the Change Healthcare merger. Centralized Snowflake warehouse with unified AI/BI accountability.
Fortune 50 ProvenBusiness 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.
6 years — Particle physics, petabyte-scale data, international collaboration
8 years — Customer analytics, marketing attribution, $100M+ savings
5 years — Analytics engineering, BigQuery at 500PB scale
VP of Data — 240-person global team, Fortune 50 merger analytics
Real outcomes from real enterprises — not consulting theater
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.
The Methodology: Mirror Analysis — treating marketing attribution like a particle physics experiment.
When Change Healthcare merged with Optum, executives needed real-time visibility across both organizations. We built the executive command center that let CEOs steer the merger in real time.
The Methodology: SPoG Blueprint — centralized Snowflake warehouse with unified AI/BI accountability.
"I like to remember Patrick as the Michael Jordan of analytics, because his talent is so unique that if you're lucky enough to meet this kind of people, your professional life changes forever."
Blue Fermion Advisory is currently not accepting new projects. Thank you for your interest — I look forward to reconnecting in the future.
How experimentation meets execution in AI. From n8n automations to enterprise-scale GenAI Ops, each episode unpacks how data, models, and human insight build intelligent systems that work in the real world.

The Physicist Executive — From discovering particles at CERN to leading 240-person analytics organizations at Fortune 50 companies.
Patrick brings a unique perspective: the rigor of experimental physics combined with 25 years of operating experience at eBay, Google, Optum, and Teradata. He invented methodologies still in use at eBay today, led the analytics integration for the Change Healthcare merger, and serves as an NACD Governance Fellow.
