Read the Cap Table Like a CFO: What Your Grant Owns
Treat a cap table as a list of claims, then check your grant after dilution before you sign.
The trap: your grant is a claim in the table
You are offered startup equity. The number sounds generous until you see the cap table. A cap table maps who owns what in a company. Your grant is a claim in the table, and later claims can shrink it.
Before you sign, read the table like a CFO. You need to see the total shares, the founder block, the investor block, the option pool, any future claims, and your grant after dilution.
The order matters. The total shares set the scale. The founder block shows who still has control. The investor block shows who already paid for a slice. The option pool shows how much room is left for people like you. The future claims show what can appear before your grant is fully measured.
The cap table is a stack of claims
Count the total shares first. Many startups issue 1,000,000 or 10,000,000 shares at the start to keep calculations simple. If the company has issued more shares since the start, use the current total, not the original number. Done means a denominator you can use to check every later percentage.
Locate the founder block. Founders usually hold the largest block, but the size matters more than the label. A large founder block can be a good sign of alignment. It can also mean less room for new grants. You can stop when you can say how much of the company the founders still control before new money arrives.
Identify the investor block. Existing investors own shares from earlier rounds. Look for the latest round, not just the first round. The step is complete when you can separate their current ownership from the people who may join later.
Measure the option pool. The pool is reserved for future employees, advisors, and contractors. Ask whether the pool will be expanded before your grant is issued. If it is, your percentage can shrink before you start. You have it when you can see how much unallocated equity is waiting to be granted.
Track the future claims. A SAFE note is a promise of future equity, usually triggered by a later round. The common mistake is treating those notes as optional. Ask when the notes convert and at what price. The step is complete when you can treat them as pending claims, not as decoration.
Calculate your grant after dilution. Your percentage is your grant divided by the post-dilution total, including the pool and future claims. If the company cannot show the post-dilution total, request the assumptions. You can stop when the number reflects the company after the next round, not the company before it.
The questions that protect your grant
Request the current cap table. A verbal summary is not the same as a table. You are ready when you have a document that lists the blocks you just read.
Check whether the 409A valuation is current. A 409A valuation for an early-stage company can cost $2,000 to $5,000. The date matters because it can affect the price of your option. You have the answer when you know the date of the last valuation and why it matters for your option price.
Review how the company tracks option grants. The IRS can hit employees with a 20% penalty tax, ordinary income tax, and interest when option-grant tracking is improper. You are ready when you know who maintains the records and what happens when a grant is amended.
Confirm who maintains the cap table. Carta, Capshare, and Pulley are cap table automation tools for growing startups. You can leave the call with a clear answer about whether the table is updated by a person, a tool, or both.
Turn the read into a decision
Write the read in plain English. Put the total shares, the founder block, the investor block, the option pool, the future claims, and your grant after dilution on a page. You have it when you can explain the table to a friend without using jargon.
Check the denominator again. If the company adds a new round, a new pool, or a new future claim, the percentage changes. You can move on when you know which claims would change your number and by how much.
Save the date of the table. The table is a dated record. You have the answer when you know when it was last updated and what event would make it stale.
