Advisory Shares: Definition, Vesting, and How VCs Read Them
Advisory shares compensate external advisors with equity. What they are, typical FAST ranges, vesting, NSO tax shape, and how VCs read them on a cap table.
Advisory shares are equity compensation granted to external advisors, usually non-qualified stock options or restricted stock, in exchange for strategic help, introductions, or specialized judgment. The phrase is startup slang, not a separate legal class of stock.
Founders use them when cash is scarce and the advice is worth more than a retainer. Advisors take them for upside that only pays if the company works. On a cap table, those grants still dilute everyone else, so the diligence question is whether the paper matches the work.
What are advisory shares?
Advisory shares are equity issued to people who are not full-time employees: former founders, operators, domain experts, or sometimes investors acting in an advisor seat. The company is buying judgment, network access, or a defined project, not a forty-hour week.
The instrument is almost always one of two things:
- Non-qualified stock options (NSOs). The advisor gets the right to buy common stock at a strike set by a 409A valuation. Most post-formation grants look like this.
- Restricted stock awards (RSAs). Actual shares issued early, when fair market value is low, subject to vesting and repurchase. More common at idea-stage companies before a formal option plan is heavy.
RSUs show up later and are uncommon for true advisors. Incentive stock options (ISOs) are reserved for employees under US tax rules, so advisors do not get them.
Advisory equity is not preferred stock from a priced round, not a SAFE, and not a convertible note. Those are financing instruments. Advisory shares sit in the common / option-pool stack unless the documents say otherwise.
Advisory shares vs equity and employee stock options
"Equity" is the broad ownership category. Advisory shares are one way to grant it. The useful contrasts are role, instrument, and rights.
| Advisory shares | Employee stock options | Investor preferred | |
|---|---|---|---|
| Who | External advisors | Employees | Funds / angels in a round |
| Typical instrument | NSOs or early RSAs | ISOs and/or NSOs | Preferred stock |
| Vesting | Often ~2 years, monthly; short or no cliff | Often 4 years with a 1-year cliff | Usually none |
| Day-to-day role | Part-time advice | Operating job | Governance via board / protective provisions |
| Voting / control | Often limited until exercised; not board authority by default | Common after exercise | Preferred rights in the certificate |
Board director equity is a different job. Directors owe fiduciary duties and usually take a board grant with its own vesting. An advisor grant does not make someone a director. Do not mix the labels on the cap table.
How much equity do advisors get?
Stage and involvement set the range. The Founder Institute FAST Agreement, also called the Founder / Advisor Standard Template, Version 3 updated July 2026, is the public benchmark founders and advisors still reach for. Its published matrix:
| Engagement | Pre-seed | Seed | Series A |
|---|---|---|---|
| Standard (monthly meetings) | 0.50% | 0.25% | 0.10% |
| Expert (add contacts / projects) | 1.00% | 0.75% | 0.50% |
Those percentages are of fully diluted capitalization for a single advisor, vesting over two years. FAST also notes that a technology startup often sets aside about 5% in total for a group of strategic advisors. That is a pool ceiling for planning, not a target to fill.
Market practice compresses as the company matures. The same monthly meeting that looks like half a percent at pre-seed may be a tenth of a percent after Series A. A name without deliverables does not earn the expert row.
Negotiate the percentage against hours, introductions, and outcomes, then put the number in the agreement. Handshake equity is how cap tables get messy before seed.
Vesting schedules for advisory shares
Advisor vesting is shorter than employee vesting because the relationship is lighter and the company changes faster.
Common pattern:
- Duration: about two years (24 months), not four.
- Cadence: monthly.
- Cliff: none, or a short trial cliff (FAST uses three months) so a dead relationship ends with zero equity.
If the advisor stops advising, unvested equity stops. Acceleration on a change of control should be explicit in the grant: single trigger on sale versus double trigger with termination. Silence here creates arguments at exit.
Do not copy a four-year employee schedule with a one-year cliff onto an advisor who meets monthly. That structure over-protects the company early and under-rewards real early help, or the reverse when someone collects for a year of low engagement.
How advisory share agreements work
Write it down before the first useful introduction.
A working agreement covers:
- 1. Role and time. Monthly calls, recruiting help, customer intros, or a named project. Vague "strategic advice" is how both sides feel cheated.
- 2. Equity type and size. NSO versus RSA, share count or fully diluted percent, and the plan the grant comes from.
- 3. Vesting. Start date, cliff, monthly rate, what happens on termination.
- 4. Confidentiality and IP. Advisors see product and fundraising plans. NDAs and IP assignment for work product belong in the packet.
- 5. Conflicts. Other portfolio companies, competitors, and fund affiliations should be disclosed up front.
- 6. Termination. Either side can usually end the relationship on short notice; unvested equity does not continue.
FAST is designed so founders and advisors can check boxes and sign without a custom negotiation for every mentor. It is free from the Founder Institute. Modify it only with counsel, and compare any markup to the original template. FAST is built for strategic advisors compensated in equity, not for work-for-hire consulting billed in cash.
Founder Institute recommends working with a candidate for at least a month and about eight hours together before discussing the equity form. That trial is cheaper than clawing back a bad grant.
Tax shape for advisors
This is orientation, not tax advice. Advisors and companies should talk to their own counsel.
NSOs. Advisors usually receive NSOs. At exercise, the spread between strike and fair market value is ordinary income. Later appreciation after exercise can be capital gain if holding-period rules are met. Payroll withholding can apply on the spread at exercise even though the advisor is not an employee.
ISOs. Employees only. Do not promise an advisor "ISO treatment."
RSAs and 83(b). If the advisor receives restricted stock, an Internal Revenue Code section 83(b) election, filed within 30 days of the grant, can tax the low early value up front instead of taxing larger amounts as the stock vests. Miss the window and the election is gone.
Strike price. Option strikes for common follow 409A. Mixing a fundraising headline with the option strike is how people invent fake bargain purchases.
Jurisdictions outside the US use different labels and tax timing. The US NSO / ISO split above is the pattern most Delaware C-corp startup packs assume.
How a VC screens advisory shares on a cap table
Founder guides stop at "give 0.25% and vest over two years." The desk reading the data room before a priced round runs a shorter list.
1. Find every advisor grant. Options, RSAs, promises in email, and "advisory board" lines that never hit the ledger. Fully diluted means promised too.
2. Name the instrument. NSO, RSA, or undefined. Undefined is a diligence flag. Confirm the grant sits in the option pool or was properly authorized.
3. Map vesting and acceleration. Start date, cliff, percent vested today, single- versus double-trigger language. A 1% grant that is 90% vested with full single-trigger acceleration is different paper from a 1% grant with twenty-two months left and no acceleration.
4. Benchmark against stage and work. Compare the grant to the FAST stage × engagement band and to what the advisor actually does. A Series A company still carrying five 1% "expert" advisors with monthly coffee meetings is a governance and dilution story, not a free networking perk.
5. Check the pool math. Advisor grants usually come out of the employee option pool. A fat advisor stack before a round forces a larger top-up, which dilutes founders and employees in the term sheet modeling.
6. Read conflicts and concentration. Same advisor on three competing seed companies. An advisor who is also writing a check. An advisor listed as a director without board minutes. Fix labels before they reach LPs.
What belongs in the memo. Advisor names, instrument, fully diluted percent, vested percent, acceleration, pool impact, conflict notes, and whether any grant should be cleaned up as a closing condition.
What does not belong. A tour of famous advisory boards, a pitch for a cap-table product, or a claim that every good company gives advisors 1%.

Common mistakes
Treating advisory shares as a special stock class. They are common equity or options with advisor-shaped terms.
Copying employee four-year / one-year-cliff vesting onto advisors. Wrong duration for the relationship.
Granting before a trial. FAST's own guidance starts with chemistry, then paper.
Filling a 5% advisor pool because the template mentions 5%. That number is a planning ceiling, not a mandate.
Handing ISOs to non-employees. US tax rules do not allow it.
Ignoring acceleration and 83(b) deadlines. Both show up as pain at exit or at vest.
Leaving advisor promises off the cap table. Diligence will find the email thread.
Frequently asked questions
What are advisory shares?
Equity compensation for external advisors, typically NSOs or early RSAs, in exchange for advice, introductions, or defined projects. Not a separate legal class of stock.
Advisory shares vs equity: what is the difference?
Equity is ownership. Advisory shares are a grant of that ownership (or options on it) to an advisor. Investor preferred and employee options are other equity forms with different rights and vesting.
How much equity should a startup advisor get?
Often roughly 0.1% to 1.0% fully diluted depending on stage and involvement. The Founder Institute FAST matrix publishes standard and expert bands from pre-seed through Series A. Individual deals still negotiate.
What is a typical advisory shares vesting schedule?
About two years, monthly, with no cliff or a short trial cliff (FAST uses three months). That differs from the common employee four-year schedule with a one-year cliff.
Are advisory shares the same as stock options?
Often they *are* stock options (NSOs). Sometimes they are restricted stock. The label "advisory shares" describes the recipient and purpose, not a unique security type.
What is the FAST agreement?
The Founder / Advisor Standard Template from the Founder Institute: a short public form for advisor role, equity percent, and vesting. Version 3 was updated July 2026.
How do VCs look at advisory shares?
As fully diluted ownership that must be authorized, vested on clear terms, sized to real work, and free of messy conflicts before a round or a liquidity event.
Advisory shares are a cash-light way to buy judgment, and a dilution line item that still has to clear diligence. Size them with stage and work, vest them on an advisor clock, and keep the grant list clean on the cap table. For the related mechanics, read cap tables, 409A valuations, term sheets, pre-seed, seed, Series A, SAFEs, and convertible notes.
