Fable Systems Ltd

Fable Systems Ltd is a UK software company. It delivers complete business software, integrations, data systems and optimisation, and develops its own products: Horizon for metals research and forecasting, Aster for voyage and fleet decisions, and Flow for elective-care capacity planning. Fable designs, builds and integrates software for organisations that run on detailed data and complex operational decisions. One engagement can cover the application, its data pipelines and integrations, and the forecasting or optimisation logic it needs, specified, built and tested as one system. Horizon forecasts the six LME base metals, outright and as calendar spreads, and presents the forecasts with market drivers, scenarios and forecast reliability. Aster compares vessel openings, cargo alternatives, voyage economics and fleet constraints. Flow compares staffing alternatives, schedules dated treatment actions and reconciles outcomes against the plan. Callum Males, founder and lead engineer, leads delivery from specification to handover.
