Quantrix

Quantrix is a spreadsheet program modeled after the pioneering Lotus Improv, and introduced by Lighthouse Design for NeXTSTEP and OPENSTEP in the early '90s when Lotus stopped selling Improv. Like Improv, Quantrix has been adopted primarily by the financial industry, where its ability to manipulate various “categories” or "dimensions" makes it easy to view forecasts, budgets, risk analysis, financial projections and all types of complex data modeling.
