This guide explains startup stock options for founders. To compete for talent, create a 10-20% employee option pool. Grants are based on role and stage, vest over 4 years with a 1-year cliff, and must use a 409A valuation to set the price. Understanding the tax differences between ISOs and NSOs is critical to avoiding major tax bills for your team.
Key takeaways
- Create a 10-20% employee stock option pool, ideally before your next financing round.
- Always grant a fixed number of shares, not a floating percentage.
- Use a standard 4-year vesting schedule with a 1-year cliff to align incentives.
- Get a 409A valuation every 12 months or after a fundraise to set the strike price.
- Clearly explain the grant details, vesting, and potential for dilution to every candidate.
- Consider extending the 90-day post-termination exercise window to be more employee-friendly.
In the early days, cash is your most precious resource. You can't outbid Google or Meta on salary to attract top-tier engineers, marketers, or product managers. This is not a battle you can win with cash.
Your competitive advantage is equity. A stock option is a contract that gives an employee the right , but not the obligation, to buy a set number of shares at a fixed price (the "strike price"). If your company grows, the value of those shares can dwarf the salary they might have earned at a big tech company. If you fail, they've lost nothing.
Getting your equity plan right is non-negotiable. A well-structured plan is a powerful tool for recruiting and retention. A poorly-structured one creates tax nightmares, cultural resentment, and legal messes. This guide provides the tactical foundation to do it right.
Before you can grant a single option, you need a pool of shares to draw from. This is your employee stock option pool (ESOP)—a specific block of common stock your board carves out for employees, advisors, and consultants. You and your co-founders should never grant shares from your personal holdings.
The standard size is 10% to 20% of your company's fully-diluted capitalization.
Pre-seed/Seed Stage: A 10-15% pool is typical. You might create this at incorporation or as part of your first priced round.
Series A: Your new lead investor will almost always require you to have a 15-20% pool.
This is a critical, non-obvious point: VC's will insist the option pool is expanded before their investment, diluting only the existing shareholders (you, your co-founders, and prior investors). They will not dilute their own new money.
Let's say you're raising a Series A at a $10M pre-money valuation with an 8M share cap table. The VCs want to invest $5M for a $15M post-money valuation and require a 20% option pool.
Your new cap table must have a 20% unallocated option pool. The VCs calculate this on the post-money capitalization.
So, $15M post-money implies the option pool needs to…

Frequently asked questions
- How big should my first option pool be?
- For a pre-seed or seed stage startup, a 10-15% option pool is standard. This is typically created when you incorporate or as part of your first financing.
- Do founders get stock options?
- No. Founders are granted founder stock (common stock) at incorporation, which is different. The option pool is exclusively for employees, advisors, and consultants.
- What's the difference between options and RSUs?
- Options give you the *right to buy* stock at a fixed price, while Restricted Stock Units (RSUs) are a *promise to grant* you stock when they vest. Startups use options; RSUs are common in liquid, public companies.
- How much equity should a startup advisor get?
- Advisor grants typically range from 0.1% to 0.5%, vested over 1-2 years. The amount depends entirely on their experience, expected time commitment, and strategic value.
- What happens to options in an acquisition?
- It depends on the deal terms. Often, unvested options are either 'accelerated' (vest immediately) or are converted into options of the acquiring company, continuing on their original vesting schedule.
