About deita

deita is the practice of Dei Martinez Elurbe: decision science for food and hospitality.

I turn messy hospitality data into decisions: what to charge, what to prep, when to staff. The methods are research-grade, the tools ship, and the conclusions come with an honest account of what the data can and cannot support.

What I do: • Pricing and market analysis: hedonic pricing, market structure, where the margin actually lives. • Demand forecasting: models that take weather, season, and events seriously. • Decision tools: reports, dashboards, and alerts that answer a question instead of decorating it.

I also build and run deitalite, weather-smart demand forecasting for independent restaurants (deitalite.eu), and I publish research like the Amsterdam menu-price study: a hedonic model of about 900 menus and 33,000 dishes, measuring who really overcharges in the city and for what (deita.eu/amsterdam-menus).

I grew up in my family's cafeterías and spent seven summers in my aunt's restaurant; then ten years as a research scientist at universities in Barcelona and Nijmegen. deita is where the two meet: decision science for an industry I know from the inside.
