Advisor equity is ownership granted to non-employee mentors or consultants, typically ranging from 0.1% to 1% of the company depending on their involvement level, company stage, and the value they bring.
Someone with an impressive resume wants to advise your startup. They’re asking for equity.
How much should you give them?
The short answer: 0.1% to 1%, depending on your stage, their involvement level, and what they actually bring to the table. Most advisors fall in the 0.25% range.
But the numbers don’t tell the whole story. The wrong advisor deal can wreck your cap table and signal to investors that you don’t understand equity. The right deal can unlock introductions, credibility, and guidance worth far more than the shares you gave up.
The 5 factors that determine advisor equity
Most guides give you a single table and call it a day. In reality, five factors interact to determine the right number:
- Company stage — Earlier means more equity. A pre-seed advisor takes on more risk than a Series A advisor.
- Time commitment — An advisor giving 1-2 hours per month is worth less equity than one embedded 5-10 hours per month.
- Expertise and network value — Generic industry knowledge commands less than deep domain expertise or a Rolodex of buyer contacts.
- Vesting structure — How equity is released matters as much as how much. Time-based vs. milestone-based vesting changes the risk profile for both sides.
- Accountability mechanism — The factor most founders skip entirely. Without a way to tie equity to deliverables, roughly half of advisor relationships lose momentum after a few months, and you’re stuck with dead equity.
The sections below dig into each of these, with benchmarks, real data, and the frameworks that help you put a number on it.
Quick reference: advisor equity ranges
The FAST Agreement from Founder Institute is the most widely used framework. FAST v3, released in June 2026, simplified the grid from three involvement levels to two:
FAST v3 (June 2026)
| Company Stage | Standard (monthly meetings) | Expert (contacts and projects) |
|---|---|---|
| Pre-seed | 0.50% | 1.00% |
| Seed | 0.25% | 0.75% |
| Series A | 0.10% | 0.50% |
Previous FAST grid (v1/v2, still widely referenced)
| Company Stage | Light Touch (1-2 hrs/mo) | Strategic (2-4 hrs/mo) | Expert (4+ hrs/mo) |
|---|---|---|---|
| Pre-seed / Idea | 0.25% | 0.5% | 1.0% |
| Seed | 0.2% | 0.35% | 0.6% |
| Series A+ | 0.1% | 0.2% | 0.35% |
Notice that FAST v3 increased the lower tiers (Standard pre-seed went from 0.25% to 0.50%) while simplifying the structure. However, real-world data tells a different story — see the next section.
What the Data Says
Carta’s 2024 data shows median advisor grants are actually declining:
- Pre-seed: 0.21% median (down from 0.25% in previous years)
- Seed: 0.11% median
- Series A+: 0.05-0.15% median
Only 10% of pre-seed advisors received 1% or more. The market is getting more rational about advisor equity.
For comparison, a first employee at pre-seed typically gets around 1.54%. An advisor contributing a few hours per month should get proportionally less.
The total advisor pool should be no more than 5% of total company equity across all advisors combined.
The Standard Vesting Schedule
Advisor equity should always vest. Never grant shares outright.
Typical Advisor Vesting Structure
| Element | Standard | Why |
|---|---|---|
| Duration | 2 years | Shorter than employee 4-year schedules |
| Cliff | 3-6 months | Protects against non-performers |
| Frequency | Monthly | Gradual vesting matches ongoing contribution |
Why 2 years instead of 4? Advisors typically deliver most value early in the relationship. Advisory relationships naturally evolve as companies mature. A shorter duration incentivizes active engagement rather than passive equity collection.
Critical provision: Include a termination clause that lets you stop vesting if the advisor disappears or stops adding value. Without this, you’re locked in even if they ghost you.

Not all advisors are created equal. Here’s when giving equity makes sense.
Green Flags
They can open doors you can’t. The right advisor can make 5-10 high-value introductions to customers, partners, or investors. If those introductions would take you years to build organically, that’s worth equity.
They have expertise you genuinely lack. Not just confirming what you already know, but teaching you things that change how you operate. Domain expertise in your industry. Experience scaling companies past where you’ve been.
They bring credibility. For some startups, having a recognized name as an advisor helps with fundraising or enterprise sales. The association itself has value.
They commit to structured engagement. Regular calls. Specific deliverables. Accountability on both sides. An advisor who treats your company seriously is worth far more than one who’s just collecting advisory positions.
According to one survey, 83% of founders believe advisors add value to their businesses. But that leaves 17% who don’t. The difference is usually in how the relationship is structured.
Vesting Explained: Everything Founders Need to Know
When Advisors Aren’t Worth It
Red Flags
They approach you. As one experienced founder put it: “A true advisor won’t ever ask you to make them an advisor. If one is asking, run.”
They’re collecting advisory positions. Some people accumulate advisor titles to pad their LinkedIn. If they’re advising 15 companies, how much attention is yours getting?
They provide only general feedback. “You should focus on product-market fit” isn’t actionable advice. It’s a platitude. Good advisors give specific, concrete guidance.
They’re solving a one-time problem. If you need help with a single legal question or a specific technical challenge, pay a consultant. Advisors are for ongoing relationships.
They can’t articulate their value. If they can’t clearly explain what they’ll contribute, they probably won’t contribute much.
One blunt take from an experienced founder: “In my experience, advisors are an anti-signal. You gave equity to people who gave neither money nor blood, sweat, and tears.”
That’s harsh, but it captures why investors scrutinize advisor grants. Bad advisor deals signal desperation or naivety. For more on what investors look for, see what investors look for in cap tables. The contrast is worth noting: the care required for advisor grants is similar to what your first employee equity decision demands — both set a precedent that every subsequent grant gets measured against.
Common Mistakes
Giving Too Much Too Early
Horror stories abound of advisors receiving 10-20% without delivering anything meaningful. One investor saw a founder give someone 20% plus 100% of their money back from first revenue. This creates dead equity that haunts your cap table.
Equity seems “free” early on. It’s not. It’s your most valuable commodity.
Rule of thumb: If you’re offering more than 1% to a single advisor without an exceptional reason, pause and reconsider.
Relying on Handshake Agreements
Verbal agreements lead to misunderstandings. “I thought we agreed to 2%” becomes “I remember discussing 2% but we never finalized it.”
Put everything in writing. The FAST Agreement is free and takes 10 minutes to complete.
No Vesting or Wrong Vesting
Granting equity upfront ties you to potentially unproductive relationships with no exit. If an advisor disappears after month two, you want their vesting to stop—not continue for two years.
Letting Desperation Cloud Judgment
Early-stage founders often overpay due to inexperience or eagerness for validation. That impressive person offering to help feels like a lifeline.
It’s not. Take time to vet relationships before formalizing them. Founder Institute recommends working with a potential advisor for at least one month and spending at least 8 hours together before discussing equity.
Real Examples
Dropbox: The $600 Million Advisor
Mark Gores, a lawyer who met the Dropbox founders at a conference, provided ongoing legal counsel and mentorship. He received 0.75% of the company.
At Dropbox’s IPO, that stake was worth over $600 million.
Was it worth it? For a long-term strategic relationship with someone who provided real value over many years—arguably yes. The key is that Gores delivered ongoing value, not a one-time introduction.
Airbnb: The Design Professor
Brian Chesky’s design professor from RISD gave early feedback on the Airbnb concept. He received a small equity grant that became significant at IPO.
The lesson: even “small” advisory grants can become life-changing when a company succeeds. Be thoughtful about who gets them.
The Advisor Sharks
On the flip side, experienced founders warn about “advisor sharks” who ask for 0.25-1% just for “the grace of their presence.” They deliver minimal value while collecting equity from multiple startups.
One CEO coach observed “more charlatans than I can count” asking for steep equity without clear value propositions.
The FAST Agreement Framework
The Founder/Advisor Standard Template (FAST) is the most widely used framework for advisor agreements. Released by Founder Institute in 2011 and updated to v3 in June 2026, it’s used by tens of thousands of startups annually.
Key Features
- Single-page agreement with checkboxes
- Pre-defined equity levels based on stage and involvement (simplified to 2 tiers in v3)
- 3-month cliff protects against bad fits
- 2-year vesting standard
- Free to use
What changed in FAST v3 (June 2026)
The biggest change is simplification: three involvement levels collapsed to two (Standard and Expert). FAST v3 also increased the low-end grants — Standard pre-seed went from 0.25% to 0.50%. This reflects the reality that even “light touch” advisors at the earliest stages take meaningful risk and deserve more than a token grant.
The FAST matrix gives you a starting point. You can negotiate from there, but having a standard framework prevents both sides from anchoring on unreasonable numbers.
The accountability gap in FAST
FAST solves the “how much” question. It doesn’t solve the “what if they stop showing up” question.
The standard FAST agreement vests equity on a time schedule — 2 years, monthly. That means your advisor earns their shares whether they make 10 introductions or zero. The 3-month cliff catches the worst cases, but an advisor who shows up just enough to clear the cliff and then drifts away still collects 21 months of equity.
This is the single biggest problem with advisor equity today. Roughly half of advisor relationships lose momentum after the first few months. The advisor gets busy, the novelty wears off, and you’re left with dead equity on your cap table that signals to investors you gave away ownership without getting value in return.
The fix is tying vesting to deliverables, not just time. Instead of “0.5% vesting monthly over 2 years,” structure it as “0.5% vesting upon completion of specific milestones”:
- 5 qualified customer introductions
- Quarterly strategy sessions attended
- Fundraising deck reviewed and refined
- 2 investor introductions that lead to meetings
This way, equity only moves when value does. The advisor stays motivated because their shares are tied to outcomes, not attendance. And you have a clear, documented record of what was delivered and what wasn’t.
Most standard agreements don’t support this kind of conditional vesting out of the box. You either need a custom legal agreement or a tool that tracks advisor contributions alongside their equity grants — turning the static FAST document into a living, accountable relationship.
What to include in any advisor agreement
- Specific responsibilities and expected deliverables
- Equity amount and type (options vs RSAs)
- Vesting schedule with cliff
- Termination clause (you can stop vesting if they’re not delivering)
- Confidentiality provisions
- Time commitment expectations
Structuring the Relationship
The equity grant is just the beginning. How you manage the relationship determines whether you get value.
Set Clear Expectations
Define what “advising” means for your specific situation:
- How often will you meet? (Monthly calls are common)
- What specific outcomes are you hoping for? (Introductions? Technical guidance? Fundraising prep?)
- How will you measure success?
Drive the Relationship
First Round Review recommends creating advisor categories: “light touch” advisors for occasional 30-minute calls, and “board advisors” who get regular updates and are on-call for critical decisions.
The founder must own and drive the relationship. Advisors who aren’t engaged will drift. It’s your job to keep them invested.
Evaluate Regularly
After 6 months, assess: Is this relationship delivering value? If not, have an honest conversation. The termination clause exists for a reason.
Frequently Asked Questions
How much equity should I give an advisor?
Typically 0.1% to 1%, depending on your stage and their involvement level. Pre-seed companies might offer 0.25-0.5% for strategic advisors; Series A+ companies typically offer 0.1-0.2%. Use the FAST Agreement framework as a starting point.
Should advisor equity vest?
Yes, always. Standard is 2 years with monthly vesting and a 3-6 month cliff. Never grant equity outright—vesting protects you if the relationship doesn’t work out.
What’s the difference between advisor options and shares?
Advisors typically receive either stock options (NSOs) or restricted stock awards (RSAs). Options give the right to purchase shares at a set price; RSAs are actual shares that vest over time. Y Combinator notes that advisor RSAs typically range from 0.2-1%, while NSOs range from 0.1-0.5%. For a deeper dive on equity types, see our guide on types of startup equity.
How do I know if an advisor is worth the equity?
Ask: Can they make specific, high-value introductions? Do they have expertise I genuinely lack? Will they commit to regular, structured engagement? If the answer to all three is yes, they’re probably worth it. If they can’t articulate clear value, pass.
What if my advisor stops contributing?
This is why vesting and termination clauses matter. If your agreement includes a termination provision, you can stop vesting when the advisor stops delivering. Better yet, tie vesting to specific deliverables instead of a time schedule — that way equity only moves when value does. Without these protections, you’re stuck with dead equity on your cap table.
What do investors think about advisor equity?
Investors scrutinize advisor grants. Multiple advisors with 2%+ stakes signals desperation or naivety. A clean cap table with reasonable advisor grants (0.1-0.5% each, totaling under 5%) won’t raise concerns. Learn more about what investors look for in cap tables.
