Pre-IPO Growth Gap Calculator
Check a real company's actual private-years timeline against Buffett's era and today's typical company — see roughly how much growth was likely captured before public investors could buy in.

How to use it:
Enter a company's founding year and IPO year (or mark it still private).
See where its timeline lands against the Buffett Era and AI Era baselines.
Adjust the growth rate assumption to see how the implied pre-IPO multiple changes.
