History main

You deserve a better spreadsheet.

Your calculations determine structural integrity. Your models drive business decisions. Your data gets published in research papers.

But you're still:

  • Emailing spreadsheets back and forth
  • budget_v3_FINAL_real_USE_THIS.xlsx
  • Afraid to make changes because something might break
  • "What version did we use for that deliverable?" (nobody knows)

A spreadsheet built for serious work.
