Equity
Also known as: stock ownership, shares
Definition
Ownership interest in a company, represented by shares or stock, which defines a person's share of control, risks, and financial returns.
The value of ownership in a business, calculated as total assets minus total liabilities, divided among shareholders.
Why it matters
Equity is the primary currency for attracting cofounders, key employees, and investors. Founders must balance giving up equity with the acceleration that capital or talent brings. Owning ten percent of a successful hundred-million-dollar company is far better than owning a hundred percent of a company that never reaches the market.
Improvement tips
- Evaluate what an investment makes possible, such as runway or market access, rather than focusing solely on ownership loss.
- Use equity strategically to align the incentives of founders, key employees, and early investors.
- Keep a clean record of all equity promises from day one to avoid legal disputes during future funding rounds.
Common mistakes
- Giving away large chunks of equity early to casual advisors or service providers who do not contribute long term.
- Viewing equity negotiations as a zero-sum game rather than a partnership to increase the success probability of the business.
- Failing to put vesting schedules on all founder and employee equity to protect the company if someone leaves early.
