Startups often can't compete with big companies on salary alone. So how do they attract top talent? One powerful tool is offering a piece of the company itself. This is done through an Employee Stock Ownership Plan, or ESOP.

At its core, an ESOP is a way to make employees part-owners. When you join a company with an ESOP, you're not just earning a paycheck. You're also gaining a stake in the company's future. If the company does well, the value of your stake can grow significantly. This aligns everyone's interests. When employees feel like owners, they're more motivated to help the business succeed.

A startup typically sets aside a percentage of its total shares into a special reserve called an option pool. This pool is reserved for current and future employees. When you're hired, you're not handed shares directly. Instead, you're granted options.

An option gives you the right, but not the obligation, to buy a certain number of company shares at a fixed price. This is called the "strike price" or "exercise price." It's usually set at the fair market value of the shares on the day your options are granted. The hope is that the company's value will increase over time, making your shares worth much more than the price you'll pay for them.

You don't get the right to buy all your shares at once. You earn them over a period of time, a process called vesting. A typical vesting schedule is four years with a one-year "cliff." The cliff means you don't receive any options until you've been with the company for a full year. After that first year, you get 25% of your options. The rest then vest gradually, usually on a monthly basis, over the next three years.
