Get Started With Our Free Course: Essential Financial Modelling

Let’s be honest.

Financial modelling hasn’t changed much in the last 20 years.

Financial modelling remains a largely manual and therefore error-prone process. Achieving structural rigour and consistency requires modeller discipline. Under pressure, we can all fall short.

We are building a suite of software tools to support modellers.

Openbox is the missing financial modelling layer for Excel. We believe the Excel is here to stay and while its lack of inherent structure is its biggest asset, it is also its biggest drawback. Openbox adds a model structuring layer on top of Excel to transform the productivity of professional modelling.

Imagine being able to share and call up your frequently used revenue, cost, asset, debt and equity components, define your timeline and have the model assembled, to any commonly used modelling standard, in minutes. That’s our vision for Openbox.

Checkbox is our internal model review tool. It’s designed specifically for models built using the FAST modelling standard and tests for a range of common errors such as formula consistency, missing units, missing row totals, unused inputs, unused calculations etc.

We developed this for our own use and deploy it to check every client model that we build. As part of our mission to raise the bar in professional modelling Checkbox will always be free.
