Founder equity / co-founder equity is your ownership stake in your startup. Most startups are structured as companies, so this ownership is reflected in the shareholding of the company you’ve set up. When we talk about your “equity,” we mean your percentage ownership of that company.

Example: If your company has 1,000 shares and you own 750 of them, you hold 75% of the company - that’s your equity stake. Simple.

Founders usually don’t hold 100% of the equity forever. You lose your equity (% ownership) in one of two ways:
This dilution usually happens when:

Example: Following on from the above example, the company issues 150 new shares to an investor and a further 50 new shares to key employees. The company now has 1,200 shares and you own 750 of them. Meaning your equity has been diluted from 75% to 62.5%.
</aside>
While dilution might sound negative (you own a smaller percentage of the company), the key question is: does it help grow the value of the business overall?
Raising capital or granting equity to key hires will dilute your ownership, but if those moves help the company grow faster or stronger, your smaller slice could end up being worth a lot more.
Think of it like this: Would you rather own 100% of a company worth $1 million, or 5% of a company worth $1 billion? (5% of $1 billion is $50 million, btw)

When considering anything that causes dilution, think critically: Do I think this will this make the company more valuable in the long run?
