One platform to run all your team’s numbers
Quickly and easily build your own data models, run the numbers, and take action with your team.


A powerful platform with a familiar face
Like a spreadsheet, but rather than connecting data cell to cell, relationships in Arithmix are built between entire dimensions (rows/columns).


Changes in one place ripple through your entire model


Write 10x-100x fewer formulas; formulas won’t break when your data changes


Easily create and compare different versions of the same model


Collaborate with your entire team in the platform

Every team is a data-driven team when given the tools and opportunity.
Millions of spreadsheet users write software to work with numbers every day, but it’s time to grow into a new solution.
