• Build financial models in hours, not weeks.

    Openbox is the missing financial modelling layer for Excel. Build better models, in less time, with zero coding error.

  • Openbox gives you financial modelling superpowers.

    Financial models are used to support business-critical decisions.

    Building and updating financial models in Excel is time-consuming, frustrating and fraught with error.

    Openbox transforms the process.

    Speed up model build

    You design the model, and specify the components to include. Openbox takes care of building the model in Excel.

    Focus on commercial logic, not model coding.

    Work in Openbox Or Excel

    Start in Openbox and built out to Excel when you're ready. Make changes in Excel if you want, and Openbox will read them back in.

    Quickly export to Power BI

    Openbox instantly creates a flat file of everything in your model. Instantly import your model into PowerBI or other visualisation tools.

  • How Openbox works.

    Transform your financial modelling workflow.


    Set up

    Focus on the business logic. Import frequently used components. Connect to external data sources. Preview in Excel at any time.



    When you're ready, Openbox builds out the full model in Excel. Share your model with anybody. Recipients of your model don't need Openbox to read or use your model.



    Make changes in Openbox or Excel. Openbox will read the changes you or others make in Excel. Update your components and use again next time.

  • Get Openbox.

    Openbox is currently in public beta. It is available for free until mid 2021.

  • Get A Professional Financial Model for Free

    What's on offer?

    A free, unrestricted, spreadsheet model

    You tell us a few details about the model you want. Then we build it in Openbox and send the resulting spreadsheet to you, for free.


    It's that simple.


    Once you have the spreadsheet, you can use it in any way you want.

    How do I get my free model?

    Just fill in this form.


    If the model you want is one that fits with our system, we'll respond with a completed model as soon as we can.


    Why are you doing this?

    It is sound business - really

    Because we think you'll like the model so much, you might come back to us for more (paid) work in future. Or tell your friends about us.


    Building financial models is what we do all day, every day. We have a team of professional modelers available to help with any more complex needs that a free model doesn't meet.


    And we want to show you what Openbox can do, and encourage you to try it for yourself. It's free too, for the next few months.
