Advisor Equity: Common Grant Sizes and Vesting Schedules Explained

Why Advisor Equity Differs From Employee Equity

Advisors operate in a different compensation model than employees. They're not drawing salary, aren't full-time, and their value is often asymmetric—a few hours monthly from the right industry veteran can be worth thousands in salary. Yet many founders either over-grant advisors (giving away 2-3% to someone who provides intermittent guidance) or under-grant (offering 0.1% and wondering why top talent declines).

The right advisor grant is a function of expected time commitment, domain expertise scarcity, and your company's current stage. The framework below helps you navigate this without leaving money on the table.

The Standard Advisor Grant: 0.25-1% Range

For a typical advisor relationship, the market standard is 0.25% to 1% of fully diluted shares. This range exists for a reason. Below 0.25%, most experienced advisors don't take it seriously—the expected upside at exit doesn't justify their engagement. Above 1%, you're treating an advisor like an operator, and they probably should be an employee.

How to interpret this range:

0.25% (Lower end): Board-level advisors (not board members, but advisors who may attend quarterly calls), passive domain expertise, or advisors in very late stage companies where their dilution is minimal. Example: You've raised $50M, your company is at $200M fully diluted, and you bring on a CMO advisor for monthly check-ins. 0.25% = 500K shares, worth roughly $3.75M at current valuation. They might spend 4-5 hours monthly. This makes sense.

0.5% (Middle range): Most strategic advisors. Expected 8-12 hours monthly, direct involvement in key decisions, warm introductions to customers/investors, or strategic guidance on market positioning. This is the default for your first 3-5 true advisors. Example: A former VP Sales joins a B2B SaaS company pre-Series A to help build the sales organization. They spend 10 hours monthly on planning, strategy, and introductions. 0.5% is appropriate here.

0.75-1% (Higher end): Reserved for founders or operators transitioning into advisory (post-departure), advisors in pre-seed/seed stage, or domain experts in especially scarce markets (AI, biotech). Example: Your first CTO is leaving to consult part-time to build a network around your series A fundraise. 1% is reasonable given their operational history with the company.

Vesting Schedules for Advisors: The Standard Model

Most advisor grants follow this structure:

Standard: 4-year vest with 6-month cliff (some use 1-year cliff)

What this means: Your advisor's grant vests 25% after 6 months, then 1/48th each month for the remaining 3.5 years. If they leave before month 6, they have zero vested shares. This aligns incentives—you want advisors who commit for a reasonable period.

Why 6 months vs. 1 year? With advisors, shorter cliffs are common because the engagement is less structured than employment. A 1-year cliff makes sense if you expect heavy involvement in the first year. A 6-month cliff is standard if you're looking for ongoing but flexible engagement.

Variations:

• 2-year vest with 6-month cliff: For advisors with lower time commitment or higher risk (early stage)
• 4-year vest with 1-year cliff: For more senior or founder-level advisors
• 3-year vest with no cliff: Rare, but used when bringing on short-term project advisors

Calculating Your Advisor Grant: Step by Step

Step 1: Determine your target percentage.

Ask yourself: How much time will this advisor realistically spend? What's their domain expertise premium? Are they giving warm intros or deep strategic input?

Time commitment guide:

• 2-4 hours/month → 0.25%
• 4-8 hours/month → 0.35-0.5%
• 8-15 hours/month → 0.5-0.75%
• 15+ hours/month or founder-level → 0.75-1.5%

Step 2: Calculate the share count.

Multiply your fully diluted shares by the percentage. If you're pre-Series A with 5M fully diluted shares and you grant 0.5%, that's 25K shares.

Step 3: Stress-test the value.

Use your 409A valuation or expected Series A valuation to estimate the grant's worth. 25K shares at $1.00/share (pre-Series A) = $25K spread across 4-year vesting = $6.25K per year. Is that reasonable for the expected time commitment? Most advisors aren't expecting six-figure annual compensation, but $5-25K in expected annual equity value feels right for meaningful advisory roles.

Common Advisor Tiers and Equity Allocation

Tier 1: Strategic domain advisors (0.5-1%)

These are industry veterans, former executives at category leaders, or deep domain experts. Example: You're building a logistics tech platform, and you bring on the former COO of a major 3PL. They spend 10-12 hours monthly on strategic guidance. 0.5% is the floor, 0.75-1% is fair market value depending on your stage.

Tier 2: Board/investor network advisors (0.25-0.5%)

These advisors provide less hands-on guidance but open doors. Example: A well-connected operator who'll introduce you to Series A VCs and join quarterly board meetings. 0.25-0.35% covers this tier.

Tier 3: Specialist advisors (0.1-0.25%)

Narrow expertise for specific projects. Example: A patent attorney helps you navigate IP strategy for 4-6 hours. 0.1% (5K shares at 5M fully diluted) might be appropriate for time-bound engagements. Some founders offer 0.1% with the understanding that the advisor may not take the engagement—and that's okay.

Tier 4: Operator advisors moving to part-time (0.5-2%)

These are founders or operators who've left your company or another company to advise/support yours. They have institutional knowledge or deep operational context. Example: Your co-founder who stepped back to focus on fundraising and advises on product direction. 0.5-1% is standard; 1-2% if they had significant equity at departure.

The Negotiation: Common Pushback and How to Respond

Advisor says: "I want 1%, I'm taking a lot of risk."

Response: "I understand advisor equity is meaningful to you. If you're expecting 1%, that suggests 15+ hours monthly commitment. Let's define that explicitly. If it's structured that way, we can discuss 0.75-1%. If it's more flexible, 0.5% is our standard for strategic advisors at this stage."

Advisor says: "What's this worth?"

Response: "0.5% on our fully diluted means about $X at our current 409A valuation. If we hit Series A at $YM, it could be worth 2-3x that. But there's risk—early equity is leveraged on execution." Don't project exit values.

You're tempted to offer 1-2% to every good advisor.

Resist this. After 5-6 advisors at 1%, you've given away 5-6% of your company to part-time roles. That's equity that should have gone to employees or retained for founder/investor alignment. Your first 3 advisors should be your best—0.5-1% is appropriate. Subsequent advisors at 0.25-0.35%.

Special Cases and Variations

Founder-to-advisor transitions: If your co-founder steps back but remains engaged, they might retain their equity and receive additional options for ongoing advisory. Example: Co-founder had 10%, transitions to 50% time, receives 0.5% more in advisor options. This avoids a second vesting cliff for existing equity.

Investor-advisors: VCs and angels sometimes advise. If they're board observers, they rarely get additional equity (their ownership stake aligns them). If they're non-investor advisors bringing specific expertise, standard rates apply.

Extended vesting for early stage: Pre-seed or seed advisors sometimes negotiate 2-year vests instead of 4-year if you expect higher turnover risk. This can work, but set a clear cliff (6 months) to ensure minimal commitment.

Key Takeaways

• Standard advisor grant: 0.25-1% of fully diluted, with 0.5% as the default for strategic advisors
• Vesting: 4-year vest with 6-month cliff is market standard; 1-year cliff for more senior roles
• Time commitment should drive your grant size: 4-8 hrs/month = 0.35-0.5%
• Grant fewer advisors at higher percentages rather than many advisors at low percentages
• Calculate grant value in today's dollars to stress-test reasonableness
• Founder-to-advisor transitions should be negotiated explicitly to avoid double-dipping
• Resist the urge to overgrant early; your best advisors will take 0.5% if the opportunity is compelling

Frequently Asked Questions

Can advisor equity be ISOs (incentive stock options) or must they be NSOs (non-qualified stock options)?

Advisors almost always receive NSOs, not ISOs. ISOs have strict IRS rules about time and price. As an advisor, you're not an employee, so NSOs are the default. This is cleaner tax-wise for both parties and standard in the market.

What if an advisor wants a higher percentage but we can't afford it?

Be explicit: "We can offer X%, and that reflects our belief in your value. We need advisors who see the upside potential in early equity rather than immediate cash compensation. If our current offer doesn't work, let's explore a smaller engagement or revisit this after our Series A." This filters for advisors who genuinely believe in your company.

Should we accelerate vesting for advisors who leave?

Generally no, unless there's a special circumstance (they're moving to an investor or customer and there's a conflict). Acceleration often signals you were overgenerous in the grant size. Stick to the vesting schedule you agreed to.

Do advisors need board consent to exercise options after vesting?

No, advisors can exercise vested options without board approval. You should have standard documentation (options agreement, stock option plan) that spells out exercise terms. Advisors should know upfront whether they need to exercise within a window after departure or if they have extended exercise windows.

Can we change an advisor's vesting if they've moved to a core role?

Yes, but handle it delicately. If an advisor becomes an employee, you might cancel their advisor options and grant them employee options with a fresh vesting schedule. This requires their consent and should be documented. Avoid the appearance of a do-over if their advisor grant is underwater.
