You did the responsible thing. You asked around. Three founders, two people who call themselves advisors, an investor you met once, and a Slack channel. Now you have more opinions than when you started, half of them contradict the other half, and the one you actually have to act on, how much of your company to hand a near-stranger for advice, is the exact thing nobody agrees on.
I have watched this play out thousands of times since starting GrowthMentor. The founder isn't short on input. They're short on one person they trust enough to make the call with. So this guide does two things: it gives you the real numbers advisors get in 2026, and it shows you how to structure the deal so you aren't the founder clawing that equity back a year later. First, the question most of these articles skip: whether this belongs on your cap table at all.
TL;DR
- Most startup advisors get 0.1% to 1% equity. The median sits around 0.25%. One rule keeps you sane: cap every advisor near 1% and apply it uniformly.
- Vest it. Two years, a short cliff, monthly after that, with a buyback so equity granted for ongoing help comes back if the help stops.
- Two named frameworks do the math: the FAST agreement (a grid by stage and involvement) and the Travis Kalanick method (a formula). Both are below with 2026 numbers.
- Equity is for ongoing, compounding involvement. For a one-off question, a consultant (cash) or a mentor is cheaper than a permanent line on your cap table.
- The expensive mistake isn't the wrong percentage. It's handing the decision to a pile of advisors and drowning in their disagreement.
Startup advisor compensation: the short answer
- Typical equity
- 0.1% to 1% per advisor
- Median grant
- about 0.25%
- Sensible cap
- around 1% per advisor, applied uniformly
- Vesting
- 2 years, 3-month cliff, monthly
- Cash alternative
- $250 to $1,500 an hour, rare early on
That's the whole answer for most founders. The rest of this page is how to land on your number inside those ranges, how to structure it so it holds up, and how to tell whether you need an equity advisor at all. If what you want is how to find and vet advisors in the first place, that lives in our guide to startup advisors.
Do you even need to give equity?
Most founders reaching for equity don't need to. They conflate three different relationships and default to ownership, when only one of the three belongs on your cap table for a single question.
Consultant vs advisor vs mentor
| Consultant | Advisor | Mentor | |
|---|---|---|---|
| You pay in | Cash | Equity, 0.1 to 1% | A flat fee, not equity |
| Cap-table impact | None | A permanent line | None |
| Commitment | A defined deliverable | Ongoing and light | On demand, as often as you need |
| Best for | A specific task done for you | Long-term, compounding involvement | Judgment on the decision in front of you |

Advisor vs mentor vs consultant
A consultant is a cash relationship: you rent a specific outcome and you are done. An advisor is an ownership relationship: you give a permanent slice of the company for ongoing, informal help. A mentor is judgment you book when you need it and never put on your cap table. The reason the distinction matters is that most of what sends founders hunting for an advisor is a decision they need to think through, not a permanent seat. For that, a mentor or a paid consultant is faster, cheaper, and reversible. Reserve equity for the person whose involvement compounds over years. (We go deeper on the mentor-versus-advisor line in advice vs mentorship, and on finding an advisor in our guide to startup advisors.)

Cash, equity, or both?
Early on, most advisor deals are equity, for the obvious reason: you don't have the cash, and equity ties their payoff to yours. Later-stage or expert advisors sometimes take a small retainer or a per-meeting fee on top. Pure cash for an advisor is rare in the early days, and when you want it, what you usually want is a consultant.
The trap is the other extreme. Equity-only looks free because no money leaves the account, but what it buys you is a misaligned relationship. Most startups never reach a liquidity event, so equity-only advisors carry real downside and tend to drift. When you can manage it, a small amount of cash plus equity buys more genuine commitment than a bigger grant alone.
Cash plus equity
- Real alignment: the advisor has something at stake now, not just at a someday exit
- Easier to set expectations and hold the relationship to them
- Signals you take both their time and your own equity seriously
Equity only
- Looks free, but most startups never reach a liquidity event, so the equity may be worth nothing
- Harder to hold someone accountable when they have spent nothing to be there
- Tempts you to over-grant ownership to make up for the lack of cash
How much equity should an advisor get?
Inside that 0.1% to 1% range, where you land comes down to two things: how much value the advisor adds, and how far along you are. One who opens doors, joins recruiting, and takes customer calls earns the top of the range. One who shows up for a monthly call earns the bottom. And the further along your company, the smaller the slice, because each point of equity is worth more.
The rule that saves you ten negotiations: pick a ceiling, around 1%, and apply it to every advisor. The moment you grant one person 1.5% because they pushed for it, the next one finds out and the whole board becomes a negotiation. A uniform standard is easier to defend and easier to live with.
How much equity for an advisory board in total?
Think in terms of the whole board, not one person. A typical advisory board lands somewhere under 1% to 2% combined, and the uniform per-advisor cap is how you hold that line. As your cap table fills and your valuation climbs, each new advisor should get less than the last.
The FAST agreement
The cleanest way to turn all of that into a number is the FAST agreement, the Founder/Advisor Standard Template from the Founder Institute (you'll also see it called the Guidelines method). It crosses two things you already know, how mature your company is and how involved the advisor will be, and hands you a grant.
The FAST equity grid (Founder Institute). The highlighted cell is the most common case, a strategic advisor at startup stage, about 0.40%. Equity falls left to right as you mature, and rises top to bottom with involvement.
Read it like this. A startup-stage company bringing on a strategic advisor, someone who joins recruiting and takes a few customer calls on top of monthly meetings, lands at 0.40%, vesting over two years. Idea-stage and expert-level is where the numbers climb, because the risk and the contribution are both highest.
The Travis Kalanick method
If you want to start from the advisor's worth instead of a grid, use the method named after Uber's Travis Kalanick, who argued the equity should simply be math. It values the advisor's time against your company and hands you a percentage.
Value your company
No round yet? Use a rough pre-money number. Most early startups land somewhere between $5M and $10M for this math.
Estimate the advisor's hours
How much time will they really give over a year? One hour a week is about 50 hours. Be honest, not aspirational.
Apply their hourly rate
What would they charge as a consultant? Senior advisors run $300 to $1,500 an hour. Rate times hours is the cash value of their year.
Divide by your valuation
That cash value divided by your company value is the equity. The result almost always lands under 1%, which is the point.
Here is that math on a real example:
- Company valuation
- $5,000,000
- Advisor rate
- $300 / hour
- Annual hours
- 50
- Contribution value
- $15,000 (300 x 50)
- Equity granted
- 0.3% (15,000 / 5,000,000)
Vesting, cliffs, and protecting your cap table
Whatever number you land on, never grant it outright. Vest it. The standard for advisors is lighter than for employees, because advisors give most of their value early.
- Vesting period
- 2 years (advisors front-load value, so shorter than the 4-year employee norm)
- Cliff
- 3 months (some founders skip it and vest monthly from day one)
- After the cliff
- Monthly
- Acceleration
- Single-trigger on acquisition
- Protection
- Reverse vesting plus a buyback right
One mechanical note worth a lawyer's time: advisor equity is usually issued as restricted stock or stock options. If it's restricted stock, the advisor will normally file an 83(b) election within 30 days of the grant to avoid a worse tax bill later. Name the instrument in the agreement so nobody is surprised.
The other half of protection is what happens when it goes wrong.
Build the exit before you sign. The advisor who collects a board title and a slice of equity, then goes silent, is common enough that the standard protections exist for them specifically. Reverse vesting lets you reclaim unvested shares if they stop contributing. A buyback right lets you repurchase what they hold. Milestone ratchets tie the next tranche to something real. None of this is hostile, and good advisors expect it.
Staring at a number and a draft agreement? A 1:1 is where you pressure-test the three things this page can't decide for you: whether to grant equity at all, where in the range to land, and what buyback clause to write in before you sign. These three have structured these deals from both sides.
Suggested mentors
Three founders and operators who've sat on both sides of the advisor deal, each from a different angle:
The mistake that costs more than the equity
Here is the part no framework covers. The most expensive mistake founders make with advisors isn't the percentage. It's handing the decision itself to the advisors. You pivot the business on one person's word, a second advisor pulls you back, and three conversations later you've moved nothing except your own confidence. The founders who talk to ten advisors at once tend to end up the most stuck.
What founders assume
What really happens
The two structural traps sit underneath that one: giving equity too cheaply, and over-valuing the commitment of an equity-only deal. Both come from the same place, wanting an outside authority to carry a decision that is yours.
The reframe that unsticks this: would you rather own 100% of a company worth a million, or 50% of one worth ten? Founders who can't part with an inch of equity for an advisor who'd genuinely accelerate them are guarding the percentage and ignoring the size of the pie. Cap the grant low, vest it, protect it, then stop counting basis points and let a great advisor do what they came to do.
What an advisor agreement should cover
When you do formalize an advisor, the agreement is short and worth getting right. It should cover:
- Scope. What the advisor will actually do, and how often
- Term. How long the agreement runs before you both revisit it
- Confidentiality. An NDA and IP assignment
- Compensation. The equity grant, the instrument, vesting, cliff, and any cash
- Protection. Reverse vesting, buyback, and what counts as not contributing
How to decide
So here is the whole thing on one page. Decide whether this even needs equity, because a consultant or a mentor often does the job without touching your cap table. If it does, cap the grant low and apply the same ceiling to everyone. Vest it over two years with a cliff, and write the buyback in before you sign. Use the FAST grid or the Kalanick formula to land the exact number, then stop optimizing basis points.
And the meta-rule, the one that matters more than any percentage: don't make this decision by committee. The founders who get unstuck aren't the ones who collected the most opinions. They're the ones who found one person they trusted, talked it through once, and made the call. Finding and vetting the advisor itself is its own job, covered in our guide to startup advisors. The harder part, deciding what they're worth and what to give, is the one to get a real second opinion on.
