Isaac Mavis
For more than fifteen years, Isaac Mavis has built the pricing, revenue management, and AI systems that decide whether commercial businesses actually make money. At Allegiant he built the data science function from nothing and the systems that priced more than a billion dollars in annual airfare. He owned revenue strategy at Avelo, helped shape commercial strategy at Priceline, and led revenue and commercial work at Sun Country. Across these roles he has taken more than one company from no AI capability to AI-driven decision systems in production. A Chicago Booth MBA with degrees in mechanical and aerospace engineering, he is the rare operator who can design the model, build the system, and sell the result to the board.
Margin.House is that work, now offered to a small number of clients at a time.
What we build
Commercial systems
Pricing engines, revenue management workflows, and network optimization fitted to a specific business. Not slideware. Working systems the commercial team can operate and trust.
AI and machine learning
Zero-to-one ML where there was none, forecasting and decision automation in production, and GenAI and LLM tools aimed at the few places they actually pay off. Built, deployed, and explained to the people who fund them.
Built to be run
Every engagement leaves something the client owns and can extend, with the founder personally accountable for the work. We will even price on results alone: no result, no fee. No layers, no surprise staffing, no extraction.
