A capitalization table (cap table) is the record of who owns what in your company: founders, employees with options, and investors, plus the share counts, percentages, and terms. It is the source of truth for ownership and dilution at every financing round.

Should founders use a spreadsheet or a cap table tool?

A spreadsheet is fine pre-funding. Once you raise, issue options, or have a SAFE converting, use a dedicated tool (Carta, Pulley, AngelList) to avoid errors that compound across rounds. The relationships behind the cap table — your investors — are separate and need their own system.

Cap Table Management Guide for Founders

Last updated: June 9, 2026

Short answer: Your cap table is the source of truth for ownership. Use a spreadsheet pre-funding, a dedicated tool once you raise. But remember — the cap table tracks shares; it doesn't track the relationships with the investors behind them. You need both.

What a cap table actually is

A capitalization table lists every owner of your company and what they hold: founder common shares, employee options, investor preferred shares, SAFEs, and convertible notes. It shows ownership percentages and how they shift — your dilution — at each round. Get it wrong and you can mis-price a round, over-promise equity, or surprise yourself at exit.

Spreadsheet vs tool — when to switch

Spreadsheet is fine when: you're pre-funding, just founders, no options issued.

Switch to a tool (Carta, Pulley, AngelList) when: you take your first SAFE or priced round, issue an option pool, or have more than a couple of stakeholders. Tools give version history, scenario modeling, and 409A support that spreadsheets can't safely match.

The mistakes that cost founders equity

Untracked SAFEs — they convert later and dilute more than you modeled.
Ignoring option-pool dilution — VCs often want the pool topped up pre-money, diluting founders not investors.
Stale spreadsheets — no single source of truth across co-founders.
No scenario modeling — you sign terms without seeing post-round ownership.
Cold investors between rounds — the relationship debt that makes the next raise harder.

The part the cap table tool won't do

Carta tracks shares. It does not tell you that you haven't spoken to your lead investor in three months, or that the angel who wants to follow on is feeling ignored. That's relationship intelligence. Aparna AI watches your investor relationships from Gmail and Calendar and flags who's going cold — so the people behind your cap table stay warm between rounds, when it matters most for the next raise.
