Modelling Innovation

We build financial models for effective decision making.
We can train your team to do the same.

Build

We use the FAST modelling standard to build flexible, transparent financial models for effective decision making.

Training

We can transform the way you and your team build models.

Software

We’re building the next generation of model build tools.

All modellers make mistakes. It’s an unavoidable fact of life. Like taxes, and reality TV. You might not expect a modelling firm to lead with this on our home page. But just wishing for something not to be true never made it so.

Although all modellers make mistakes, not all models have mistakes in them. We developed a software tool to check for common errors. We use it on all our models. And we want to share it with you. For Free. All we ask is that you give us your feedback to help us keep making it better.

Checkbox, our free Excel Add-in will check for:

+ formula inconsistency
+ hard coded inputs
+ unused calculations
+ FAST modelling standard compliance
+ unused range names

And a whole bunch of other stuff you may never have considered testing for.
