What Is Equity in a Startup? Shares, Ownership and Dilution Explained
By The PeepStart Team ·
Equity means ownership. If you own equity in a startup, you own a slice of the company. Understanding how that slice is measured — and how it shrinks as the company raises money — is essential for founders, employees and anyone curious about investing.
Shares and ownership percentage
A company divides its ownership into shares. Your ownership percentage is simply your shares divided by the total shares issued. Owning 1,000 shares means little until you know the total.
What dilution means
When a startup raises money by issuing new shares, the total number of shares grows. You keep the same number of shares, but your percentage goes down. That's dilution.
A simple worked example (illustrative numbers)
- Two founders own 5,000 shares each — 10,000 total, 50% each.
- An angel invests and receives 2,500 new shares. Total is now 12,500.
- Each founder still has 5,000 shares, but now owns 40%. The angel owns 20%.
Dilution isn't automatically bad: if the money helps the company become much more valuable, a smaller slice can be worth far more.
Valuation: pre-money and post-money
Pre-money valuation is what the company is valued at before new money comes in. Post-money is pre-money plus the new investment. The investor's percentage is roughly their investment divided by the post-money valuation.
ESOP pools
Startups often set aside shares for employee stock options. Creating or expanding an ESOP pool also dilutes existing shareholders, and investors sometimes ask for it to be created before their investment.
Not all shares are equal
Investors frequently receive preference shares (in India, often compulsorily convertible preference shares) that can carry extra rights, such as getting paid first in a sale. Read the terms, not just the percentage.
Frequently asked questions
Is dilution always bad?
No. It's a trade-off: a smaller share of a more valuable company can be worth more than a bigger share of a struggling one.
What is a cap table?
A capitalisation table lists who owns which shares and options in a company. Founders should keep it accurate from day one.
