Key Takeaways
- 72% of VC-backed startups offer stock options to all full-time employees, rising to 89% at Series A and beyond (Carta State of Private Markets, 2025)
- The median employee option grant at Seed stage ranges from 0.1% to 0.5% for individual contributors and 0.25% to 1.5% for VP or C-level hires (AngelList Venture Data Report, 2024)
- Four-year vesting with a one-year cliff is used by 94% of VC-backed startups for employee grants, unchanged from 2023 (Carta, 2025)
- Only 38% of employees who hold vested options actually exercise them within the standard 90-day post-termination exercise window, leaving significant equity unclaimed (Pave Compensation Survey, 2025)
- The median 409A fair market value at Seed stage is roughly 10-20% of the most recent preferred share price, rising to 30-50% of preferred at Series B (Carta, 2025)
Stock options are the most common form of equity compensation at venture-backed startups, and also the most misunderstood. Employees conflate option grants with shares owned, miss the 90-day exercise deadline when they leave, and often have no idea what their strike price is or what exit scenario would make the grant worth exercising. The startup employee stock options statistics below, drawn from Carta, AngelList, Pave, PitchBook, and Index Ventures, map what the data shows in 2026 across equity prevalence, grant sizes by role and stage, vesting terms, 409A trends, and how many employees actually end up with money in their pockets.
How common are stock options at startups in 2026?
Equity compensation is close to universal at funded startups, but much rarer at bootstrapped or pre-revenue companies. Carta's State of Private Markets report (2025), drawing on cap table data from over 50,000 VC-backed companies, found that 72% of all VC-backed startups offer stock options to all full-time employees. That figure rises sharply with funding stage.
Share of startups offering equity to full-time employees by stage (Carta, 2025):
| Funding stage | % offering equity to all full-time employees | % offering equity to some employees |
|---|---|---|
| Pre-seed / bootstrapped | 31% | 19% |
| Seed | 61% | 18% |
| Series A | 89% | 8% |
| Series B | 94% | 5% |
| Series C+ | 97% | 2% |
The gap between pre-seed and Series A reflects both investor expectations and the legal overhead of setting up a formal equity plan. Seed-stage companies that have not yet done this often delay until the Series A, when investors and new hires start requiring it as a condition.
Index Ventures' 2024 Rewarding Talent report, covering 600+ European and US startups, found that 83% of US Series A companies offer equity to every full-time hire, compared to 54% of their European counterparts. US startup culture treats options as a standard component of total compensation rather than something reserved for senior hires or technical roles.
Pave's 2025 Compensation Survey, covering 8,200+ VC-backed companies, found that 68% of companies with 10-50 employees offer options to all employees, rising to 91% at 50-200 employees, where dedicated HR makes administration more tractable.
Option pool size statistics by funding stage
At incorporation, most startups reserve 10-15% of fully diluted shares as an option pool for future employee grants. That pool gets partially consumed with each new hire, then topped up - usually pre-money - at each financing round.
Typical option pool size by stage (Carta, 2025 / First Round Capital, 2024):
| Stage | Option pool as % of fully diluted shares | Shares typically unallocated |
|---|---|---|
| Incorporation | 10-15% | 100% of pool |
| Post-Seed | 10-15% | 60-75% of pool |
| Post-Series A | 10-15% (post-close, typically topped up pre-money) | 50-65% of pool |
| Post-Series B | 8-12% | 40-55% of pool |
| Post-Series C | 5-10% (targeted refresh) | 30-50% of pool |
AngelList's 2024 Venture Data Report, covering 8,000+ portfolio companies, found that the median option pool available for new grants at Series A is 12.4% of fully diluted shares. At Series B, 60-70% of the original option pool allocated at Seed has already been granted, leaving a smaller unallocated reserve.
Investors typically require the option pool to be set pre-money at Series A, not post-money. The dilution from the pool falls on founders and existing shareholders, not on incoming investors. First Round Capital's 2024 analysis shows this pre-money pool requirement adds an average of 4-7% of additional effective dilution beyond the headline percentage sold in the round.
Kruze Consulting's 2025 Startup CEO Benchmarks report found that companies with more than 80% of their option pool allocated entering a new financing round negotiate from a weaker position. Investors typically require a pool top-up as a condition of the term sheet, and the size of that top-up is set by the investor's model of future hiring needs, not by the company's actual plan. Maintaining 20-30% unallocated buffer going into each raise is common guidance.
Employee equity grant statistics by role and seniority
Grant size varies by hire order, seniority, and funding stage. The most consequential variable is when someone joins relative to the company's valuation trajectory - an early employee taking 0.5% at a $10M Seed valuation and a later hire taking 0.1% at a $100M Series A can have similar expected dollar returns at a typical exit.
Median individual stock option grants by role level at Seed stage (AngelList, 2024 / Pave, 2025):
| Role level | Median grant (% fully diluted) | Range |
|---|---|---|
| Employee #1-5 (any function) | 0.50% | 0.25-2.0% |
| Employee #6-20 | 0.20% | 0.05-0.50% |
| Employee #21-50 | 0.10% | 0.01-0.25% |
| Individual contributor (post-Series A) | 0.05-0.15% | 0.01-0.30% |
| Manager / team lead | 0.10-0.25% | 0.05-0.50% |
| Director level | 0.20-0.50% | 0.10-1.00% |
| VP level | 0.40-1.00% | 0.25-1.50% |
| C-suite (non-founder, post-Series A) | 0.75-2.00% | 0.50-4.00% |
Pave's 2025 survey of 8,200+ companies adds role-specific benchmarks at Series A:
Median option grants by function at Series A (Pave, 2025):
| Function | Median grant (% fully diluted) |
|---|---|
| Software engineer (mid-level) | 0.08% |
| Senior software engineer | 0.15% |
| Staff / principal engineer | 0.25% |
| Engineering manager | 0.20% |
| Head of engineering | 0.40% |
| VP of Engineering | 0.75% |
| CTO (non-founder) | 1.25% |
| Head of sales / revenue | 0.30% |
| VP of Sales | 0.60% |
| Head of marketing | 0.25% |
| VP of Marketing | 0.50% |
| Head of product | 0.30% |
| VP of Product | 0.60% |
| CFO (first finance hire) | 0.75% |
Index Ventures' 2024 Rewarding Talent benchmarks define three tiers: Exceptional (top 25% of grants), Standard (median), and Baseline (bottom 25%). Their data for a Series A software engineer shows the Exceptional tier at 0.20% fully diluted, Standard at 0.10%, and Baseline at 0.05% - closely aligned with Pave's 2025 figures.
Vesting schedule statistics
The four-year vest with a one-year cliff is the near-universal standard. Carta's 2025 data shows it appears in 94% of VC-backed startup employee grants, unchanged from 2023. Alternatives exist but are uncommon enough that they merit an explanation when offered.
Vesting structure breakdown in VC-backed startups (Carta, 2025):
| Vesting structure | % of employee grants |
|---|---|
| 4-year vest, 1-year cliff, monthly thereafter | 71% |
| 4-year vest, 1-year cliff, quarterly thereafter | 23% |
| 3-year vest, 1-year cliff | 4% |
| 2-year vest, no cliff (typically advisors) | 1% |
| Other / custom | 1% |
The cliff - typically the 12-month mark - is the date that matters most. Employees who leave before it receive nothing. Carta's 2025 data shows that 22% of employees at VC-backed startups depart before the one-year cliff, forfeiting 100% of their option grants. An additional 31% leave between the one-year and two-year marks, retaining only 25-50% of their original grant.
Cumulative vesting percentage at departure (Carta, 2025):
| Tenure at departure | Vested portion (4-year schedule, 1-year cliff) |
|---|---|
| Under 12 months | 0% |
| 12 months | 25% |
| 18 months | 37.5% |
| 24 months | 50% |
| 36 months | 75% |
| 48 months | 100% |
Refresh grants - additional option grants given to employees who have significantly vested their initial grant - are common at Series B and beyond. Pave's 2025 data shows that 64% of companies with 50+ employees issue refresh grants annually or at performance review cycles. The median refresh for a senior engineer who has fully vested is 50-75% of their original grant size.
Acceleration provisions in employee grants are less common than in founder agreements. Carta's 2025 analysis finds that only 12% of standard employee option grants include any acceleration provisions, versus 38% of founder grants. When acceleration is included in employee agreements, 87% of cases use double trigger (change of control plus involuntary termination), not single trigger.
409A valuation statistics and trends
The 409A valuation sets the fair market value (FMV) of common stock, which determines the strike price for new option grants. A lower 409A means a lower strike price and more potential upside for employees. The ratio between the 409A FMV and the most recent preferred share price is one of the most practically useful numbers in a startup equity negotiation, because it tells employees how far the company needs to grow before their options are in the money relative to what investors paid.
Median 409A FMV as % of most recent preferred share price by stage (Carta, 2025):
| Funding stage | Median 409A FMV / preferred price | Range |
|---|---|---|
| Pre-seed | 8-15% | 5-25% |
| Seed | 10-20% | 8-35% |
| Series A | 20-35% | 15-50% |
| Series B | 30-50% | 25-60% |
| Series C | 40-60% | 35-70% |
| Series D+ / pre-IPO | 50-80% | 45-90% |
The discount between common (employee) stock FMV and preferred (investor) stock price reflects structural differences: preferred stock carries liquidation preferences, anti-dilution rights, and other economic protections that common stock lacks. Earlier-stage companies show larger discounts because the outcome uncertainty is higher and the liquidation preference stack matters more in proportion to total value.
IRS Section 409A requires that the strike price of incentive stock options (ISOs) be set at or above FMV at the time of grant. Granting options below FMV creates significant tax liability for the employee and penalties for the company. Compliance requires an independent 409A appraisal from a qualified valuation provider.
409A valuation frequency and cost benchmarks (Kruze Consulting, 2025):
| Triggering event | Typical timing |
|---|---|
| New funding round | Within 90 days post-close |
| Annual requirement | Every 12 months if no funding event |
| Material change in business | Within 90 days |
| Pre-IPO / M&A process | Typically every 6 months |
| Company stage | Median 409A appraisal cost |
|---|---|
| Pre-seed / Seed | $1,200-$3,500 |
| Series A | $2,500-$6,000 |
| Series B+ | $5,000-$15,000 |
Carta's 2025 data shows that the lag between a new funding round and the first post-round option grants has shortened. In 2022, the median lag between a Seed close and new grants was 47 days. By 2024 it had dropped to 28 days, reflecting faster turnarounds from software-based 409A providers and better founder awareness that delayed grants cost employees the benefit of the lower pre-round strike price.
Employee exercise rate statistics
Option exercise is voluntary. Employees pay the strike price to convert options into shares, which requires personal capital and confidence that the shares will be worth more than the exercise cost. Many don't.
Employee stock option exercise rates (Pave, 2025 / Carta, 2025):
| Scenario | Exercise rate |
|---|---|
| Employees who exercise at departure (within 90-day window) | 38% |
| Employees who exercise during secondary market opportunity | 51% |
| Employees who exercise pre-IPO tender offer | 74% |
| Employees who let options expire at termination | 62% |
| Employees who exercise all available options at IPO | 81% |
The 90-day post-termination exercise (PTE) window is where most equity disappears. Standard option agreements give departing employees 90 days to exercise their vested options or lose them permanently. Pave's 2025 data found that the median strike price for an employee who joined at Seed stage and departed after three years of vesting is $0.42 per share. Exercising 100,000 options at that strike costs $42,000 in personal capital, with no guaranteed path to liquidity. Of employees who forfeit options at departure, 62% cite the upfront cost as the reason.
Extended PTE windows address this directly. Carta's 2025 data shows that 24% of VC-backed companies now offer PTE windows longer than 90 days, up from 11% in 2021. Of those, the most common extension is 5 years (61% of companies that extend the window), followed by 10 years (31%) and the full option term (8%).
Early exercise - exercising options immediately after grant, before vesting, by filing an 83(b) election - is a separate tax-minimization strategy that lets employees lock in a low FMV for capital gains purposes. Carta's 2025 data shows 29% of employees at early-stage startups who are offered early exercise rights use them, up from 18% in 2022. Early exercisers who leave before full vesting may request a refund of the exercise price for unvested shares under the company's repurchase right.
Employee participation statistics
Not every eligible employee receives a grant, and not every grant is on equal terms.
Option grant participation rates at VC-backed startups (Carta, 2025):
| Company size | % of employees holding active option grants |
|---|---|
| 1-10 employees | 89% |
| 11-50 employees | 76% |
| 51-200 employees | 62% |
| 201-500 employees | 48% |
| 500+ employees | 37% |
Participation rates drop at larger companies because hourly, contract, and part-time workers are typically ineligible, and because later hires at scaling companies are more likely to receive cash compensation increases rather than equity. Pave's 2025 survey found that 71% of companies with 200+ employees have two-tier offer structures: equity for full-time salaried employees, none for contractors and hourly staff.
Index Ventures' 2024 Rewarding Talent report found that US startups grant options to a broader employee base than their European counterparts: 89% of US Series A companies offer options to all full-time hires, versus 54% in Europe. The difference traces to cultural norms and less favorable tax treatment for options in several European jurisdictions.
The more sobering data is on comprehension. Pave's 2025 survey found that 54% of employees who hold option grants cannot accurately state their strike price, 67% do not know their company's most recent 409A valuation, and 71% have not modeled what their options would be worth at various exit scenarios. Holding equity and understanding it are two different things, and the gap is wide.
Dilution impact on employee grants
Dilution affects every existing shareholder at each new funding round, including option holders. Early employees hold a larger percentage of a smaller company; later hires hold a smaller percentage of a larger company. Which position is better depends entirely on the exit.
Dilution effect on an early employee's grant across funding rounds:
| Round | Company valuation (post-money) | Employee's original 0.5% grant (fully diluted %) | Implied value of grant |
|---|---|---|---|
| Grant date (Seed) | $10M | 0.50% | $50,000 |
| Series A | $50M | 0.38% (after ~25% dilution) | $190,000 |
| Series B | $150M | 0.30% (after further ~20% dilution) | $450,000 |
| Series C | $400M | 0.24% (after ~18% dilution) | $960,000 |
| Exit at $500M | $500M | 0.24% | $1,200,000 (before preferences) |
The implied values above do not account for liquidation preferences, which reduce employee proceeds in lower-valuation exits. Carta's 2025 analysis of 600+ acquisitions found that in exits below 1.5x the most recent round's post-money valuation, employees with common stock received 20-40% less than their ownership percentage implied, after preferred liquidation preferences were satisfied.
AngelList's 2024 data shows that cumulative dilution from Seed through Series C typically runs 50-65% for employees who held grants from the Seed stage. A 0.5% Seed-stage grant is most commonly worth 0.18-0.25% on a fully diluted basis by the time the company reaches Series C, assuming standard option pool refreshes and three rounds of financing.
PitchBook's 2024 US Venture Ecosystem Report found that the median pre-money valuation at each stage has risen 22% since 2021 for companies that reached Series B, which has partially offset the dilution impact for early employees in successful companies. In absolute terms, a Seed-stage individual contributor grant at a company that reaches a $400M Series C exit is worth roughly $800,000-$1.2M before preferences, based on median grant sizes and dilution paths.
What the data means for employees and founders
A grant expressed as a percentage is not a fixed value - it is a claim on whatever common shares are worth at exit, after liquidation preferences are applied and after dilution has run its course. Employees who receive 0.1% of a company at a $20M valuation should track both the percentage and the exit scenario math, not just accept the headline number.
The 90-day exercise window is also a retention mechanism that founders often overlook. Employees who have accumulated significant vested equity but cannot afford to exercise are effectively locked in by unvested shares. Extending the PTE window to five or ten years removes that particular trap and, according to Pave's 2025 retention data, correlates with higher satisfaction scores and lower involuntary-exit-driven forfeitures. The trade-off is a longer tail of outstanding options on the cap table - worth modeling before doing it, but generally a favorable exchange for companies with strong employee retention goals.
The 409A strike price at grant is the most consequential number in an offer letter that most candidates never ask about. A company that just closed a funding round and has not yet completed its post-round 409A appraisal is in a window where the FMV may still reflect the pre-round valuation. Employees who join immediately post-round before the new 409A is complete can receive grants at the pre-round strike price, which offers more upside. It is worth asking.
