The point behind the play

This started as a simple business idea.

Inventory. Pricing. Weather. Demand. Cash. We turned it into a stateful application with forecasting, simulation, analytics, local persistence and export. The same approach can turn a spreadsheet, workflow or expensive software problem into something focused and useful.
