Startup Equity - Evaluating What Your Options Are Really Worth
Reading time: ~45 min | Interview relevance: High | Roles: MLE, AI Eng, Research Scientist, Founding Engineer, MLOps
The Real Interview Moment
You are sitting across from the CEO of a Series B AI startup. They have just made you an offer: 20K signing bonus, and 0.15% equity. "At our last valuation," the CEO says, "that equity is worth about 1.2 million on top of a solid base salary. Your big-tech offer from Google is $385K total comp. This startup offer seems to blow it away.
But then you start asking questions. The 0.15% is in stock options, not shares. The valuation is 180,000 in cash within three months, you lose everything. And the company has already raised four rounds of funding, so your 0.15% will likely be 0.08% by the time there is a liquidity event.
Your friend who joined a startup three years ago tells you: "My equity is worth $3 million on paper." What they do not tell you is that they cannot sell a single share, the company has not gone public, and the last tender offer valued shares at 40% of the last funding round price.
This chapter teaches you to see through the hype and evaluate startup equity with the rigor of an investor, not the optimism of a recruit.

Part 1 - Stock Options Fundamentals
What Are Stock Options?
A stock option gives you the right to buy company shares at a fixed price (the strike price) in the future. Unlike RSUs at public companies, options require you to pay money to "exercise" them, and they are only valuable if the company's share price rises above your strike price.
Key Stock Option Concepts
| Concept | Definition | Example |
|---|---|---|
| Grant | The total number of options in your offer | "10,000 stock options" |
| Strike price | The price you pay per share to exercise | $2.00 (set by the 409A valuation) |
| Vesting schedule | When options become exercisable | 4 years, 1-year cliff, monthly thereafter |
| Exercise | Buying shares at the strike price | Paying 20,000 |
| FMV (Fair Market Value) | Current assessed value of shares | $8.00 per share at time of exercise |
| Spread | FMV minus strike price at exercise | 2.00 = $6.00/share |
| Exercise window | Time after leaving to exercise vested options | 90 days (standard) to 10 years (generous) |
| Expiration | When unexercised options disappear | Typically 10 years from grant date |
Part 2 - ISO vs NSO: The Tax Divide
The difference between Incentive Stock Options (ISOs) and Non-Qualified Stock Options (NSOs) is one of the most consequential distinctions in startup compensation. It can mean a difference of 500,000+ in taxes on a successful exit.
Side-by-Side Comparison
| Feature | ISO (Incentive Stock Option) | NSO (Non-Qualified Stock Option) |
|---|---|---|
| Who gets them | Employees only | Employees, contractors, advisors |
| Annual limit | $100K in value vesting per year | No limit |
| Tax at exercise | No regular income tax (but AMT may apply) | Ordinary income tax on the spread |
| Tax at sale | Long-term capital gains (if holding period met) | Ordinary income on spread + capital gains on additional appreciation |
| Holding period for LTCG | 2 years from grant + 1 year from exercise | 1 year from exercise |
| Employer deduction | No | Yes (company gets deduction = your income) |
| Complexity | Higher (AMT, dual cost basis) | Lower |
Tax Calculation: ISO vs NSO on the Same Grant
Scenario: 10,000 options, strike price 10, sale price at IPO $30
| Step | ISO | NSO |
|---|---|---|
| Exercise cost | 2) | 2) |
| Spread at exercise | 8) | 8) |
| Regular income tax at exercise | $0 | 35,200 (37-44% on $80K) |
| AMT at exercise | 80K) - may be recoverable | N/A |
| Sale proceeds | 30) | 30) |
| Capital gain at sale | 300K - $20K cost basis) | 300K - $100K cost basis) |
| Tax on sale | 280K) | 200K) |
| Total tax | 89,040 | 82,800 |
| Net proceeds | 233,360 | 222,800 |
Many engineers assume ISOs are always better than NSOs. In reality, the AMT (Alternative Minimum Tax) triggered by exercising ISOs can create a large tax bill in the year of exercise - even before you can sell the shares. If you exercise ISOs in a year where the spread is large and you cannot sell (because the company is still private), you could owe tens of thousands in AMT with no cash to pay it. This is exactly what happened to thousands of employees during the 2000 dot-com bust. Always model AMT exposure before exercising ISOs.
The $100K ISO Rule
Only $100,000 worth of ISOs (based on FMV at grant date) can vest in any calendar year. Options vesting above that threshold are automatically treated as NSOs.
Example: You receive 50,000 ISOs with a strike price of 37,500 in value per year. This is under the $100K limit, so all options remain ISOs.
But if you receive 200,000 ISOs at 150,000. Only 3.00 = 33,333 options per year qualify as ISOs. The remaining 16,667 are automatically NSOs.
"ISOs give you potential tax advantages \text{---} no regular income tax at exercise \text{---} but they trigger AMT and require a two-year holding period from grant plus one year from exercise for long-term capital gains. NSOs are taxed as ordinary income at exercise but are simpler and have no AMT risk. For most startup employees, the ISO vs NSO distinction matters most if the company succeeds and you hold shares through IPO. If you exercise and sell immediately at IPO, the tax difference is meaningful but not transformative. Where it becomes life-changing is if you exercise early and hold through a large appreciation."
Part 3 \text{---} Understanding Your Equity Percentage
What 0.15% Actually Means
When a startup offers you "0.15% equity," that number is almost meaningless without context. You need to know:
- 0.15% of what? \text{---} The current fully-diluted share count
- What is the share count? \text{---} Total outstanding shares + option pool + convertible instruments
- What happens at the next fundraise? \text{---} Your percentage shrinks (dilution)
- What are the liquidation preferences? \text{---} Investors may get paid before you
Fully-Diluted Share Count
| Component | Shares | % of Total |
|---|---|---|
| Founder shares | 6,000,000 | 40.0% |
| Seed investors | 1,500,000 | 10.0% |
| Series A investors | 2,250,000 | 15.0% |
| Series B investors | 3,000,000 | 20.0% |
| Employee option pool (allocated) | 1,500,000 | 10.0% |
| Employee option pool (unallocated) | 750,000 | 5.0% |
| Fully-diluted total | 15,000,000 | 100% |
Your 0.15% = 22,500 shares out of 15,000,000.
AI Startup Equity Benchmarks by Role and Stage
| Role | Seed (Pre-$10M) | Series A ($10-50M) | Series B ($50-200M) | Series C ($200M-1B) | Late Stage ($1B+) |
|---|---|---|---|---|---|
| Founding Engineer (#1-3) | 1.0-3.0% | N/A | N/A | N/A | N/A |
| Early Engineer (#4-10) | 0.25-1.0% | 0.10-0.50% | N/A | N/A | N/A |
| Senior MLE | 0.15-0.50% | 0.05-0.20% | 0.02-0.10% | 0.01-0.05% | 0.005-0.02% |
| Staff MLE | 0.25-0.75% | 0.10-0.30% | 0.05-0.15% | 0.02-0.08% | 0.01-0.04% |
| AI Research Scientist | 0.20-0.60% | 0.08-0.25% | 0.03-0.12% | 0.015-0.06% | 0.008-0.03% |
| VP/Head of AI | 0.50-2.0% | 0.25-1.0% | 0.10-0.50% | 0.05-0.25% | 0.02-0.10% |
| AI Eng Manager | 0.15-0.50% | 0.05-0.20% | 0.02-0.08% | 0.01-0.04% | 0.005-0.02% |
AI/ML specialists consistently command 1.5-2.5x the equity of equivalent-level software engineers at the same startup stage. This premium is most pronounced at Series A and B, where the company's core AI capabilities are being built and ML talent is directly tied to product differentiation. By Series C and beyond, equity packages start converging with standard software engineering levels, though research scientists often maintain the premium.
Part 4 - Dilution: How Your Percentage Shrinks
How Dilution Works
Every time a startup raises money, new shares are created and given to investors. This increases the total share count, reducing your percentage ownership - even though your number of shares stays the same.
Dilution Over Multiple Rounds
Starting with 0.15% at Series B:
| Event | New Shares | Total Shares | Your % | Dilution |
|---|---|---|---|---|
| Series B (start) | - | 15,000,000 | 0.150% | - |
| Series C ($100M) | 5,000,000 | 20,000,000 | 0.113% | -25% |
| Option pool expansion | 2,000,000 | 22,000,000 | 0.102% | -10% |
| Series D ($200M) | 4,000,000 | 26,000,000 | 0.087% | -15% |
| Pre-IPO round | 2,000,000 | 28,000,000 | 0.080% | -8% |
| At IPO | - | 28,000,000 | 0.080% | -47% total |
Your 0.15% became 0.08%. Nearly half your ownership was diluted away. This is typical - most startup employees experience 40-60% dilution between joining and a liquidity event.
Anti-Dilution Protection (You Do Not Have It)
Investors typically negotiate anti-dilution clauses (weighted average or full ratchet) that protect their ownership percentage when a down round occurs. As an employee, you have no anti-dilution protection. Your shares dilute in every round, up or down.
When a startup tells you "your equity is worth $1.2 million at our current valuation," ask: "What is my ownership percentage after the next two fundraising rounds?" If they say they do not plan to raise again, ask for their current burn rate and runway. Most AI startups at Series B have 18-24 months of runway and will need to raise again. Your equity will be diluted. Plan for it.
Part 5 \text{---} Liquidation Preferences: Who Gets Paid First
The Waterfall
Liquidation preferences determine the order in which proceeds from a sale or IPO are distributed. Investors almost always have a preference over common shareholders (which includes employees with stock options).
Types of Liquidation Preferences
| Type | How It Works | Impact on You |
|---|---|---|
| 1x Non-Participating | Investors get 1x their investment back OR convert to common (whichever is higher) | Best for employees - investors only benefit once |
| 1x Participating | Investors get 1x back AND share in remaining proceeds pro-rata | Worse - investors double-dip |
| 2x Non-Participating | Investors get 2x their investment back OR convert | Much worse at low exit values |
| 2x Participating | Investors get 2x back AND share pro-rata | Worst case - your equity is significantly devalued |
Liquidation Preference Scenario Analysis
Company raised $200M total, you own 0.08% at exit
| Exit Value | No Pref | 1x Non-Part | 1x Participating | 2x Non-Part |
|---|---|---|---|---|
| $100M | $80K | $0 | $0 | $0 |
| $200M | $160K | $0 | $0 | $0 |
| $300M | $240K | $80K | $56K | $0 |
| $500M | $400K | $240K | $216K | $80K |
| $1B | $800K | $640K | $576K | $480K |
| $3B | $2.4M | $2.24M | $2.02M | $2.08M |
| $10B | $8.0M | $7.84M | $7.06M | $7.68M |
At exit values below the total amount raised, your equity is worth exactly 200M and sells for $200M, every dollar goes to investors. The founders and employees get nothing. This happens more often than people think \text{---} acqui-hires and fire sales are common outcomes. When evaluating startup equity, your analysis should assume the exit must exceed the total capital raised before your shares have any value.
Part 6 \text{---} 409A Valuations and What They Mean
What Is a 409A Valuation?
A 409A valuation is an independent appraisal of a private company's common stock (the shares underlying your options). It is required by IRS Section 409A to set the strike price of stock options. The valuation is performed by a third-party firm (e.g., Carta, Aranca, Silicon Valley Bank) and is typically updated annually or after a significant event (fundraise, revenue milestone).
409A vs Preferred Stock Price
The 409A valuation of common stock is almost always significantly lower than the price investors paid for preferred stock, because:
| Factor | Impact | Typical Discount |
|---|---|---|
| Lack of marketability | You cannot sell common shares | 15-35% discount |
| Lack of voting rights | Common stock has fewer rights | 5-15% discount |
| Liquidation preference | Preferred gets paid first | Varies |
| Total typical discount | 409A vs preferred price | 50-80% discount |
Example:
| Metric | Value |
|---|---|
| Last funding round price (preferred) | $20.00/share |
| 409A valuation (common) | $5.00/share |
| Discount | 75% |
| Your strike price | $5.00/share |
Why This Matters for Your Options
Your strike price is set at the 409A valuation, not the preferred stock price. This is good for you:
| Scenario | Preferred Price | 409A / Strike | Exit Price | Your Gain Per Share |
|---|---|---|---|---|
| Company does OK | $20 | $5 | $25 | $20/share (400% return) |
| Company does great | $20 | $5 | $100 | $95/share (1,900% return) |
| Company flat | $20 | $5 | $20 | $15/share (300% return) |
| Company declines | $20 | $5 | $4 | $0 (options underwater) |
"The 409A valuation sets my strike price for stock options - it is the IRS-mandated fair market value of common shares, which is typically 50-80% lower than what investors paid for preferred shares. This discount exists because common shares lack the protections that preferred shares have - liquidation preferences, anti-dilution rights, and board seats. A lower 409A means a lower exercise price for me, which is favorable. However, I should not confuse a low 409A with a low company value - they are different things."
Part 7 - Exercise Windows: The Hidden Cliff
The 90-Day Trap
The standard stock option agreement gives you 90 days after leaving a company to exercise your vested options. If you do not exercise within that window, your options expire - regardless of how much they are worth.
The Cash Trap: Exercise Costs at Scale
| Shares Vested | Strike Price | Exercise Cost | Tax on Exercise (NSO, ~40%) | Total Cash Needed |
|---|---|---|---|---|
| 10,000 | $2.00 | $20,000 | 60K spread) | $44,000 |
| 25,000 | $3.50 | $87,500 | 175K spread) | $157,500 |
| 50,000 | $5.00 | $250,000 | 400K spread) | $410,000 |
| 100,000 | $8.00 | $800,000 | 800K spread) | $1,120,000 |
For NSOs, you owe ordinary income tax on the spread (FMV minus strike) at exercise - even though you cannot sell the shares because the company is private. This means you need the exercise cost PLUS the tax bill in cash, within 90 days.
Extended Exercise Windows
Some employee-friendly companies offer extended exercise windows:
| Window | Companies That Offer This | Pros | Cons |
|---|---|---|---|
| 90 days (standard) | Most startups | Industry default | Forces expensive decision on departure |
| 1 year | Some growth-stage startups | More time to plan | ISOs convert to NSOs after 90 days |
| 5 years | Coinbase (historically), some AI startups | Much more flexibility | ISOs still convert after 90 days |
| 10 years (full term)** | Pinterest (historically), Quora | Maximum flexibility | ISOs convert; less common |
Before accepting any startup offer, ask: "What is the post-termination exercise window?" If the answer is 90 days, understand that you may need to come up with 500,000+ in cash within three months of leaving, or lose your equity entirely. This is the single most punishing clause in standard option agreements. If the company will not extend it, factor the exercise cost into your total compensation analysis as a real liability.
Negotiating Extended Exercise Windows
This is one of the most valuable things you can negotiate:
"I noticed the post-termination exercise window is 90 days. Given that the company is private and I would have no way to sell shares to cover the exercise cost and tax, could we extend the window to [5 years / 10 years / full option term]? This is increasingly standard at AI companies competing for top talent, and it would give me significantly more confidence in the equity component of the offer."
Part 8 - Early Exercise and 83(b) Elections
What Is Early Exercise?
Some companies allow you to exercise options before they vest. This sounds counterintuitive, but it has a powerful tax advantage when combined with an 83(b) election.
How 83(b) Works with Early Exercise
83(b) Tax Comparison
Scenario: 10,000 options, strike 20, sale at IPO $50
| Event | Without 83(b) | With 83(b) Early Exercise |
|---|---|---|
| At exercise (vest date, FMV=$20) | Ordinary income tax on 74K tax) | N/A (already exercised at $1) |
| At grant (day 1, early exercise) | N/A | Tax on 0 |
| At sale ($50/share) | LTCG on 50-71,400 | LTCG on 50-116,620 |
| Total tax | ~$145,400 | ~$116,620 |
| Tax savings | - | $28,780 |
The savings come from converting ordinary income (190K at ~23.8%) \text{---} a 15%+ rate difference on the appreciation during the vesting period.
83(b) Election Checklist
| Step | Action | Deadline |
|---|---|---|
| 1 | Early-exercise your options (pay the exercise cost) | As soon as possible after grant |
| 2 | File 83(b) election with the IRS | Within 30 calendar days \text{---} NO EXCEPTIONS |
| 3 | Send copy to employer | Same deadline |
| 4 | Keep copy for your records | Permanent |
| 5 | Include with tax return | File year |
The 83(b) filing deadline is 30 calendar days from exercise. There are no extensions, no exceptions, no "I forgot." If you miss this deadline, the election is invalid and you lose the tax benefit permanently. Set a calendar reminder for the day you exercise. File the election the next business day. Send it via certified mail for proof of delivery.
When 83(b) Does NOT Make Sense
| Situation | Why It Is Risky |
|---|---|
| High spread at exercise | You pay tax on value you might lose if you leave |
| Company is risky / might fail | You paid cash to exercise shares that might be worth $0 |
| You might leave before full vesting | Unvested shares are repurchased - you lose the exercise cost |
| FMV is significantly above strike | Tax on the spread is real money, even with 83(b) |
Part 9 - Modeling Realistic Exit Scenarios
The Expected Value Framework
Do not evaluate startup equity at its "current valuation." Model multiple scenarios and probability-weight them.
AI Startup Exit Scenario Model
Assumptions: Series B AI startup, 200M, 1x participating preferred
| Scenario | Exit Value | Probability | Your Pre-Tax Payout | Probability-Weighted Value |
|---|---|---|---|---|
| Company fails | $0 | 25% | $0 | $0 |
| Acqui-hire ($50M) | $50M | 15% | $0 (below pref) | $0 |
| Small exit ($300M) | $300M | 15% | $56K | $8,400 |
| Good exit ($1B) | $1B | 20% | $576K | $115,200 |
| Great exit ($3B) | $3B | 15% | $2.02M | $303,000 |
| Unicorn exit ($10B) | $10B | 8% | $7.06M | $564,800 |
| Mega exit ($30B) | $30B | 2% | $21.4M | $428,000 |
| Expected value | 100% | $1,419,400 |
But this is the gross expected value. Now subtract:
| Deduction | Amount |
|---|---|
| Exercise cost (10K shares x $5 strike) | -$50,000 |
| Tax on exercise (NSO, ~40% on spread) | -$40,000 |
| Tax on sale (~25% on gain) | -1,419,400) |
| Time value of money (5 years at 7%) | -30% discount |
| Net present expected value | ~$680,000 |
Over 4-5 years, this works out to approximately 170,000 per year in expected equity value. Compare that to the 250,000 per year in RSU income you would receive at a FAANG company - and the RSUs are liquid and near-certain.
Startup equity is a high-variance lottery ticket, not a compensation guarantee. The expected value might be reasonable, but the distribution is bimodal: either it is worth nothing or it is worth a lot. There is very little middle ground. If you need the money to be real (mortgage, family, loans), FAANG RSUs are the safer bet. If you can afford the risk and are optimizing for upside, startup equity can be transformational - but only at the right company, the right stage, and the right terms.

| Potential upside (5yr) | Moderate (stock appreciation) | Very high or zero | High or moderate |
Part 11 \text{---} Negotiation Scripts for Startup Equity
Asking for More Equity
"I appreciate the equity grant of 0.15%. Based on my research into Series B AI company benchmarks, senior ML engineers typically receive 0.10-0.20% at this stage, with candidates who have [specific expertise] receiving grants toward the higher end. Given that I am taking a $150K+ annual cash compensation reduction compared to my FAANG offer, I would like to discuss bringing the equity to 0.25% to close the gap on expected value."
Negotiating Exercise Terms
"I would like to discuss two modifications to the stock option agreement. First, extending the post-termination exercise window from 90 days to at least 5 years - this is becoming standard at AI companies competing for top talent, and it significantly changes my risk calculation. Second, enabling early exercise with 83(b) election capability, which benefits both of us by allowing me to start the capital gains holding period clock earlier."
Asking About Liquidation Preferences
"Could you walk me through the liquidation preference stack? Specifically: What is the total participating preferred? Are there any participation caps? What does the waterfall look like at a 3x and a 5x multiple of the last round valuation? This helps me model the realistic value of my equity at different exit scenarios."
Requesting a Secondary Sale
"Given that the company is private and my equity is illiquid, has the company considered allowing employees to participate in secondary sales or tender offers? Even a small liquidity window would materially change how I value the equity component."

Part 13 \text{---} Common Startup Equity Mistakes
| Mistake | Consequence | How to Avoid |
|---|---|---|
| Valuing equity at "current valuation" | Overestimating by 2-10x | Model multiple exit scenarios with probabilities |
| Not accounting for dilution | Thinking you own 0.15% when you will own 0.08% | Model 2-3 more funding rounds |
| Ignoring liquidation preferences | Thinking you get paid in proportion to ownership | Map the preference stack before accepting |
| Missing the 83(b) deadline | Losing $20-100K+ in tax savings | File within 30 days, no exceptions |
| Not negotiating the exercise window | Forced to come up with $100K+ cash in 90 days | Ask for 5-10 year window |
| Treating paper value as real compensation | Making financial commitments based on illiquid equity | Only count cash comp for budgeting |
| Not asking about secondary sale policies | Holding illiquid equity for 5-10 years | Ask during negotiation |
| Joining post-Series C for equity upside | Limited upside with high dilution already in place | Early-stage offers more equity leverage |
Part 14 \text{---} Secondary Markets and Tender Offers
What Are Secondary Sales?
Secondary sales allow employees to sell some of their vested shares to external buyers before an IPO. This provides liquidity for shares that would otherwise be locked up for years.
| Method | How It Works | Who Participates |
|---|---|---|
| Company-organized tender offer | Company invites shareholders to sell at a set price | All eligible shareholders |
| Secondary marketplace (Forge, EquityZen, Hiive) | Third-party platforms match buyers and sellers | Must check company's ROFR (right of first refusal) policy |
| Direct private sale | Negotiate directly with an interested buyer | Requires company approval in almost all cases |
Tender Offer Pricing
Tender offers typically price shares at a discount to the last preferred round:
| Company Stage | Typical Tender Discount to Last Round | Rationale |
|---|---|---|
| Series B | 30-50% discount | High risk, limited revenue traction |
| Series C | 20-40% discount | Growing but still pre-profitability |
| Series D+ | 10-30% discount | More mature, closer to IPO |
| Pre-IPO (1-2 years out) | 5-20% discount | Reasonable visibility to liquidity |
How Tender Offers Affect Your Decision
When evaluating a startup offer, ask: "Has the company done tender offers in the past? Do they plan to?"
| Tender Offer Policy | Impact on Your Equity Value |
|---|---|
| Regular tender offers (annually or bi-annually) | Significant \text{---} you can get partial liquidity every 1-2 years |
| One-time tender (in response to employee demand) | Moderate \text{---} some liquidity, but unpredictable |
| No tender offers | Equity is fully illiquid until IPO or acquisition |
| Explicit prohibition on secondary sales | Maximum illiquidity \text{---} your equity is locked until exit |
A startup offer with 0.15% equity and regular tender offers is fundamentally different from the same offer with no liquidity path. If you can sell 25% of your vested shares at a tender offer each year, your equity becomes partially liquid \text{---} more like RSUs with a discount. Ask about liquidity policy before you accept. It should be a top-3 question in your equity evaluation.
Part 15 \text{---} Startup Equity Tax Planning
Tax Planning Timeline
Annual Exercise Strategy
If you cannot early-exercise but want to manage your tax exposure, consider exercising a portion of your vested options each year:
| Year | Vested Options | Exercise This Year | Cumulative Exercised | Benefit |
|---|---|---|---|---|
| Year 1 | 2,500 | 2,500 | 2,500 | Start LTCG clock; small spread = low tax |
| Year 2 | 5,000 | 2,500 | 5,000 | Spread tax across years; Year 1 shares approach LTCG |
| Year 3 | 7,500 | 2,500 | 7,500 | Year 1 shares now qualify for LTCG if sold |
| Year 4 | 10,000 | 2,500 | 10,000 | Fully exercised; all shares on LTCG clock |
This strategy spreads the AMT/ordinary income impact across multiple tax years instead of concentrating it all at a liquidity event.
Qualified Small Business Stock (QSBS) Exclusion
If the startup meets certain criteria, you may qualify for the QSBS exclusion under IRC Section 1202:
| Requirement | Detail |
|---|---|
| Company is a C-corporation | Most VC-backed startups are |
| Gross assets under $50M at time of issuance | Must be under threshold when shares are issued |
| Stock held for 5+ years | From exercise date (or 83(b) date) |
| Active business requirement | Must be a qualifying trade or business |
| Benefit | Exclude up to $10M or 10x cost basis from federal capital gains tax |
Example: You exercise 10,000 shares at 20K cost basis). After 5 years, you sell at 500K. If QSBS applies, the entire 114,000 (at 23.8% LTCG).
QSBS eligibility has many requirements and exceptions. Not all startups qualify. State treatment varies (California does not conform to QSBS). This can be worth $100K+ in tax savings, so it is absolutely worth investigating, but you need a tax professional to confirm eligibility. Do not assume you qualify.
Part 16 - Startup Equity FAQ
"Is startup equity even worth taking seriously?"
Yes, but with realistic expectations. Startup equity is not free money - it is a high-risk, high-reward component of compensation. For every engineer whose startup equity made them a millionaire, there are dozens whose equity was worth zero. The key is to evaluate it like an investment: probability-weighted expected value, not best-case fantasy.
"What if the company offers me a choice between more cash or more equity?"
This depends on your financial situation and risk tolerance. If you can comfortably cover your expenses on the lower cash option, taking more equity gives you greater upside. If you need the cash to pay bills, take the cash - equity you cannot afford to hold is equity you will be forced to give up during an exercise window crunch.
"Should I negotiate equity or cash?"
At early-stage startups (seed to Series A), equity negotiation has the most leverage - the company is cash-constrained and equity is cheap. At later stages (Series C+), the company has more cash but equity is expensive (higher 409A, more dilution). Negotiate both, but know which lever has more room at each stage.
"What is the difference between shares and options?"
Shares are ownership. You own them outright. Options are the right to buy shares at a specific price. Most startup employees receive options, not shares. Founders typically receive shares (via restricted stock), and investors receive preferred shares. Your options convert to common shares when you exercise them.
"My offer says the equity is worth $X based on the last round valuation. Is that real?"
No. That is the maximum theoretical value assuming: (1) the stock price does not change, (2) there is no further dilution, (3) there are no liquidation preferences, and (4) there is a liquidity event at exactly that price. After accounting for all four factors, the realistic value is typically 20-50% of the "headline" number.
"How do I find out the fully-diluted share count?"
Ask directly: "What is the current fully-diluted share count, including the unallocated option pool?" The company is not legally required to tell you, but reputable startups will share this. If they refuse, that is a red flag - they may be hiding heavy dilution.

Next Steps
Now that you understand how to evaluate startup equity, the next chapter covers a different challenge - what happens when you have multiple offers on the table simultaneously. Move to Chapter 5: Managing Multiple Offers to learn how to time your interview process, use competing offers ethically, and make the right choice under pressure.
If you need to compare your startup equity against RSU packages at public companies, refer back to Chapter 3: RSUs and Equity for the public company framework.
