Understanding Equity and Stock Options in a Remote Startup Offer

Equity compensation is one of the more genuinely confusing parts of evaluating a startup offer, and the headline number of shares or the percentage ownership figure alone tells you very little about actual real-world value without understanding several other factors. This guide covers what actually matters when evaluating an equity offer and the specific questions worth asking before accepting.

The Main Types of Equity Compensation

Stock options (most commonly ISOs — Incentive Stock Options, or NSOs — Non-Qualified Stock Options) give you the right, not the obligation, to purchase shares at a fixed strike price, and are the most common form of equity at early-stage startups. RSUs (Restricted Stock Units) are outright grants of actual shares (not requiring purchase) that vest over time, and are more common at later-stage private companies or public companies. The distinction matters for both the mechanics of realizing value and for tax treatment, which differs meaningfully between the types and is genuinely worth understanding, or getting professional tax advice on, before making decisions about exercising options specifically.

Strike Price and Why It Determines Real Value

The strike price is the fixed price at which you can purchase your options, set based on the company's valuation at the time the options were granted (specifically, the 409A valuation, a formal independent appraisal). The actual value of an option comes entirely from the gap between this strike price and the real share value at a later point — if the company's valuation never rises meaningfully above the strike price, the options carry no real value regardless of how many were granted, which is why understanding a company's current valuation and growth trajectory matters more to evaluating an equity offer than the raw number of options alone.

Vesting Schedules and Cliffs, Explained

A four-year vesting schedule with a one-year cliff is the standard, most common structure: no equity vests at all if you leave before the one-year mark, a substantial chunk (typically 25%) vests at exactly one year, and the remainder vests incrementally (monthly or quarterly) over the following three years. This structure means the actual, realized value of an equity grant depends heavily on how long you actually stay — an offer that looks attractive based on total granted shares is meaningfully less valuable if you're likely to leave before a significant portion has vested, which is worth factoring honestly into how much weight to place on equity when comparing offers.

Dilution: Why Your Percentage Ownership Shrinks Over Time

As a startup raises additional funding rounds, it issues new shares to new investors, which mathematically reduces (dilutes) the percentage ownership represented by existing shares, including employee equity, unless additional shares are granted to offset it (which doesn't happen automatically or universally). This is a normal, expected part of startup fundraising, not necessarily a red flag on its own, but it does mean a percentage ownership figure quoted at the time of an offer will very likely be smaller by the time of any eventual liquidity event, which is worth understanding as a normal dynamic rather than a surprise.

The Real, Underappreciated Risk: Equity Can Be Worth Nothing

This is genuinely the most important and most commonly underweighted fact about startup equity: the substantial majority of startups, even well-funded ones with credible teams and products, do not reach an outcome that makes employee equity meaningfully valuable — many are acquired for modest sums that don't clear preferred-investor liquidation preferences before common shareholders (including most employees) see anything, many simply shut down, and even successful companies can take a decade or more to reach a liquidity event. Equity should be evaluated honestly as a real but genuinely high-variance, uncertain component of compensation, not treated as guaranteed additional value equivalent to its theoretical paper worth at grant.

Questions Worth Asking Before Accepting an Equity Offer

• What is the company's most recent 409A valuation, and what's my strike price relative to it?
• What's the total number of fully diluted shares outstanding, so I can understand what my grant actually represents as a percentage?
• What is the vesting schedule, and is there a cliff?
• How much runway does the company currently have, and when do you expect to raise again?
• What happens to unvested and vested-but-unexercised options if I leave the company?

FAQs

What's the difference between ISOs, NSOs, and RSUs?

ISOs and NSOs are both options with different tax treatment; RSUs are outright share grants that vest over time, more common at later-stage or public companies.

What does 'strike price' actually mean and why does it matter?

It's the fixed price you'd pay to exercise your options. The option's value comes from the gap between strike price and actual share value if the company's valuation rises.

How many years does equity typically vest over, and what does 'cliff' mean?

A four-year schedule with a one-year cliff is standard — zero equity if you leave before one year, then a chunk vests, with the rest vesting incrementally afterward.

Is it possible for equity to be worth genuinely nothing even at a well-funded company?

Yes — most startups, even well-funded ones, don't reach an outcome that makes employee equity meaningfully valuable. It should be evaluated as high-variance, not guaranteed value.
