GRND
Started: Mar 25, 2026
A browser roguelike that turns startup business models into gameplay, pick a class, set your assumptions, watch the simulated market punish them.
GRND ("shell of a building") was built for Module 2 of the EDIH Elevator Ignite Accelerator. The thesis: a business model is a spreadsheet, and you only really understand it once you live inside it. Players pick an archetype (SaaS, marketplace, ...), set their assumptions and make monthly decisions. Quarterly board meetings force a forecast-vs-actual reckoning. Cash to zero means game over.
React + Zustand + Vite + Recharts. Deterministic engine: 62 events, 25 of them with `dynamicFeedback` (right answer depends on state, product quality, pipeline, churn, LTV:CAC). Balance tuning live: burn rate, conversion corridor, PMF threshold, pipeline decay. Excel export via SheetJS in-browser, no backend.
