3rd Deviation Information

3rd Deviation is the advisory practice of Matt Klein. The name comes from statistics. The third standard deviation captures the rarest 0.3% of outcomes, the edge of the distribution where the compounding returns live and where most operators never reach. That is the work. Twenty years building, scaling, and fixing ecommerce businesses. Two of my own, sold and closed out clean. Hundreds of millions in cumulative revenue managed across every channel that matters. I have been the person in the seat when the warehouse misses its window, when the PO acceptance rate craters, when the agency is burning a million dollars a quarter and somebody finally has to say it out loud. Now I help leadership teams see what they are missing and build the systems to capture it. The work is whatever the work is. A twelve-week build of a profitability system that shows where margin is leaking across eight channels. A morning helping a founder decide whether to fire their agency. A million dollars of advertising spend redirected. A team rebuilt around the targets that matter. Sometimes it is AI. Often it is operational judgment, the kind that only comes from running the operation. When AI is the right tool, I ship AI. Forecasting that corrects for stockout distortion. Content engines that generate channel-ready copy from one source of truth. Custom models built around the operational problem, not the other way around. The systems learn. Every correction compounds. What starts as a tool becomes an intelligence layer that sharpens every quarter your team runs it. I am also Vice President of Ecommerce and AI Strategy at a multi-brand consumer goods company, running Amazon, marketplaces, DTC, and AI across six brands with a fraction of the team this kind of operation usually requires. 3rd Deviation works with companies doing $10M to $100M+ that need an operator, not an advisor. Founders who would rather hear the truth than a deck. The rarest results require the rarest perspective.
