How much equity to give an advisor: grants by stage

Carta medians: 0.21% at pre-seed, 0.12% at seed, 0.05% at Series A. FAST tops out at 1%. Vest monthly over two years with no cliff or a 3-month cliff.

A typical seed advisor gets about 0.12% of the company. Carta's median advisor grant in the first half of 2024 was 0.21% at pre-seed, 0.12% at seed, and 0.05% at Series A. The Founder Institute's FAST template sits above that: 0.25% for a standard seed advisor and 0.75% for an expert one, with 1% as its ceiling at pre-seed. Vest it monthly over two years, with no cliff or a three-month cliff. Grant NSOs or restricted stock from the option pool, with board approval. Not legal or tax advice.

This page covers outside advisors. For a VP or other hire, use executive equity grants by stage. For an independent board seat, use when to add an independent director.

Three more data points narrow the range:

Cooley GOA 24-month option normally covers 0.15–0.75% of fully diluted stockDepends on activity, importance, and company maturity

Walker adds that biotech, hardware, and medical devices run higher, and that many companies have one or two advisors. There is no reliable public benchmark yet for 2025 seed and Series A advisor grants, or for grants split by advisor type. Treat the Carta H1 2024 seed and Series A medians as the latest published figures.

Labeled example

Editorial arithmetic. Not a company and not a market rate.

Your seed company has 10,000,000 fully diluted shares. You use Cooley GO's method: pick a monthly rate, then grant 24 months of it. You pick 1 basis point a month.

TermResult
Grant24 × 0.01% = 0.24%, or 24,000 shares
Monthly vesting1,000 shares
Vested at a 3-month cliff3,000 shares
Vested if the advisor stops at month 99,000 shares

That grant sits at Walker's 2025 pre-seed median and above Carta's seed median. At seed, you would need a reason, such as an advisor who will open customer doors you cannot open yourself.

Standard vs strategic advisors

FAST prices the grant on two inputs: company stage and how involved the advisor is. Its page names standard, strategic, and expert levels and publishes the standard and expert rows.

Advisor typeWhat they doWhere to landSource
StandardMonthly meetingsNear the Carta medianFAST; Carta
ExpertAdds contacts and hands-on projectsToward the FAST expert cellFAST
Brand-name or deep domainCredibility or expertise you cannot get elsewhereTop of the rangeWalker
Strategic angelAdvises and also invests, even $2,000Grant plus their own checkWalker; Carta

Cooley GO's three tests for size are how active the advisor will be, how critical they are to the company, and how mature the company is. If an advisor scores high on only one, stay near the median.

Tie part of a strategic grant to outcomes. Carta's milestone examples: help close a priced seed round, make three strategic partnership introductions, or help recruit a key executive. Walker saw grants with terms like a set percentage for introducing two new hires.

Vesting and cliff choices

TermCommon defaultSource
Length24 months; Cooley GO grants 12–24 monthsCarta; Cooley GO; FAST
ScheduleMonthlyCarta; Cooley GO
CliffNone, or 3 monthsCooley GO and Carta (none); FAST and some Carta agreements (3 months)
Acceleration on a saleMany advisors negotiate single triggerCarta; Cooley GO
Exercise window after the role endsMost plans give 3 months; advisors can negotiate longer on NSOsCooley GO

Keep it at two years. Cooley GO says most advisors have a shelf life of less than 2 years. A longer schedule means you must end the relationship to stop the vesting. A three-month cliff lets you end a weak fit at no cost. FAST builds one in.

Say yes to acceleration on a sale if you value the advisor. Cooley GO calls it reasonable and would rather accelerate 24 months of options than 36 or 48.

NSOs vs restricted stock and 83(b)

FeatureRestricted stock (RSA)Non-qualified stock option (NSO)
What the advisor getsShares now, subject to vestingThe right to buy shares later at the strike price
When it fitsVery early, before a funding round, while FMV is lowAfter the company has a valuation
Tax timingOrdinary income on the value of the sharesOrdinary income at exercise on the spread over strike, then capital gains on sale
Your protectionCompany can repurchase unvested sharesMost plans give 3 months to exercise vested options after the role ends (Cooley GO)

Sources: Carta advisory shares guide; IRS Form 15620 for the 83(b) timing.

Advisors are not employees, so they get NSOs, not ISOs (Cooley GO; Carta). If you grant restricted stock subject to vesting, the advisor can file an 83(b) election. The deadline is 30 days after the transfer, with no extension (IRS Form 15620). Tell them the date. Do not advise them on the tax. Carta warns founders against giving tax advice to advisors or employees.

Grant from the option pool. Signing the advisor agreement is not enough: Carta says to follow the issuance process and document board approval. FAST notes a 5% pool for a group of advisors is not uncommon. Check that number against your hiring plan before you set one aside.

When not to give equity

Project work. FAST is not built for consulting or work-for-hire. Pay a consultant cash for a defined deliverable.

Someone you have not tested. The Founder Institute recommends at least one month and 8 hours together before you discuss the agreement.

Light time demands. Carta quotes Amit Bhatti of 500 Global: equity makes sense if you will be demanding on the advisor's time.

A cut of money raised. The VEN (Venture Executive Network) session judgment: do not pay anyone a share of the capital they help you raise. Attorneys in the room treat that as broker-dealer pay, with the company exposed. Grant time-based equity or ask the advisor to invest.

An oversized ask. The same VEN sessions read a large ask as a sign the advisor does not know early-stage equity. Walk away or counter at the median.

A crowded advisory table. Walker: many companies have one or two advisors, and very few have a much larger table. Add up your current grants before you add another.

Advisor grant before you sign

  1. Test the fit first. One month and a small request before any equity talk (FAST).
  2. Write the role. Expertise, time commitment, and what they will do each month (Carta).
  3. Pick the stage row. Start at the Carta median for your stage.
  4. Move up only for named work. Expert help, hard-to-get intros, or a specialized field.
  5. Set a monthly rate and grant 24 months of it (Cooley GO).
  6. Choose the cliff. None, or three months for an untested advisor.
  7. Pick the instrument. Restricted stock while FMV is low, NSOs after a valuation (Carta).
  8. Decide on acceleration and the exercise window.
  9. Get board approval and sign the grant from the pool (Carta).
  10. Ask if they will invest too. A small check makes the advisor a strategic angel (Walker; Carta).
