Group 11468-2

A word from our developers.

Call upon over a decade of data and development

"Our asset model results from nearly 15 years of iteration, formed after our mathematical and financial experts first helped the FSA, now the FCA, introduce stochastic modelling for regulated products in 1999."

Predict probability, not just binary outcomes

"...Because our calculation engine can create stochastic forecasts, as well as deterministic, you can calculate probability – e.g. the likelihood of a financial plan’s success – giving you more nuanced financial insight."
