Your cap table is one of the most important documents in your company. Get it wrong, and it can delay fundraises, kill acquisitions, and create legal liability. Here are five mistakes we see founders make, and how to avoid them.
1. Running Your Cap Table in a Spreadsheet
Spreadsheets are the default for early-stage companies, and they work until they don't. The problems compound over time:
- Multiple versions floating around with conflicting data
- Formula errors that go undetected for months
- No audit trail for changes
- Manual calculations for dilution, vesting, and conversions
During due diligence, investors will scrutinize your cap table line by line. Errors erode trust and can delay or kill deals.
2. Informal Equity Promises
Telling an early employee "we'll give you 2%" without documenting it creates phantom equity. These are promises that aren't reflected on the cap table. When it's time to formalize, the terms get disputed, and relationships break down.
Every equity commitment should be documented, board-approved, and recorded on your cap table immediately.
3. Skipping Founder Vesting
If a co-founder with 40% equity leaves after six months, you have a serious problem. Without vesting, they walk away with their full stake. A standard 4-year vesting schedule with a 1-year cliff protects everyone.
4. Ignoring Convertible Notes and SAFEs
Many founders track their priced rounds but forget to model the impact of outstanding convertible notes, SAFEs, and warrants. These instruments convert into equity at future rounds and can change ownership percentages in a big way.
Your cap table should always reflect the fully diluted picture, including all instruments that may convert.
5. Waiting Until Due Diligence to Clean Up
The worst time to fix your cap table is when an investor is waiting on it. Scrambling to reconcile records, track down signatures, and correct errors under deadline pressure leads to mistakes and lost leverage.
Maintaining a clean, real-time cap table from day one means you're always ready for fundraising, acquisitions, or any equity event.
