Leave a Startup Before a Year Is Up and Your Stock Options Are Worth Zero
After a year, some options vest at once, then more month by month, usually over four years.

CareerZ Cast · Watch this Before a High-Risk Startup JourneyJoin a tech startup with stock options in your offer letter, and none of those options are yours to use for the first year.
That is the one-year cliff. As Marcio Saito, a veteran of building tech startups, puts it: "You must survive on the ship for a period, usually 12 months, before a single option becomes exercisable. If you leave or get laid off at month 11, you walk away with nothing."
Cross that cliff and the math changes. Part of your options vest at once, meaning they become effective, and then more vest a little at a time each month, usually over four years.
In other words, the offer letter is a promise that only starts paying after a year of survival. Leave early, for any reason, and the equity part of your pay is zero.
Questions people ask
Why do startups have a one-year cliff at all?
It protects the company from giving equity to people who do not stay. Startups invest heavily in hiring and training, and equity is meant to reward lasting contribution, not a few months of work. The cliff also encourages employees to think carefully before joining.
What happens to my options if I stay past the cliff and then leave?
The options that have already vested do not turn into cash on their own. You generally have a limited window, often 90 days, to exercise them, which means paying the preset strike price to buy the shares. If you do not exercise in time, you lose them.
Is the 12-month cliff negotiable?
At early-stage startups, it is usually standard and hard to move. Very senior hires sometimes negotiate a shorter cliff, early vesting, or a signing grant of actual shares. Most rank-and-file employees should assume the 12-month rule applies.
