STEM business-modelling software for industry

STEM enables a more productive way of working, a direct path to results and a modelling style which is adaptable by design.

Our STEM modelling software is a professional tool which generates rapid financial insights with integrity. The STEM modelling process imposes a discipline suitable to illuminate the revenue and cost dynamics of business situations in any industry.


STEM is designed specifically for the agile development of business models that must be regularly adapted to match the evolving shape of an operator’s revenues and costs. The established STEM modelling process lets you focus on the network configuration and business dynamics while STEM manages the integrity of the underlying calculations.


STEM automatically generates a demand and cost allocation framework, geographical variants and scenarios, and calculates consistent service revenues, equipment installation, utilisation and replacement, capex and opex. Hundreds of results are delivered through an integrated charting interface, which can drill down into individual elements, revenues and costs. STEM includes parameters for working capital, tax and interest, borrowing and equity, and provides full profit and loss, cashflow and balance sheet outputs.
