Cap Table

Your cap table and your books in the same system

Your cap table lives in Carta. Your books live in QuickBooks. Nobody can answer 'what does dilution look like after the next round?' without exporting data from both systems and running a spreadsheet model.

How it works

StartOS manages share classes, funding rounds, equity grants, and vesting schedules alongside your general ledger. Dilution modeling runs against real cap table data. Vesting alerts notify you before cliffs hit.

  • Share class management (Common, Preferred, Options, SAFEs)
  • Funding round tracking with pre/post-money valuation
  • Equity grant management with vesting schedules
  • Dilution modeling for equity rounds, convertible notes, and SAFEs
  • Runway impact analysis (current vs post-raise cash and runway)
  • Vesting milestone alerts (cliff approaching, pool utilization)
  • Investor visibility via portal (with founder-controlled gate)
  • 409A fair market value tracking
