How Much Equity Should I Give a Startup Advisor, and What Goes in the Agreement?

Your startup is gaining momentum. An experienced founder, industry expert, or well-known executive offers to become an advisor. They promise introductions, strategic guidance, and help with fundraising.

In return, they ask for equity.

You agree in principle, exchange a few emails, and decide to finalize the paperwork later.

That approach often creates problems.

Without a written agreement, a clear scope of work, and a vesting schedule, advisor equity can become permanent ownership that provides very little value to the company. Structuring advisor relationships properly from the beginning helps founders reward meaningful contributions while protecting the cap table.

How Much Equity Is Typical for a Startup Advisor?

Advisor equity should generally be modest.

According to the Founder Institute’s FAST (Founder/Advisor Standard Template) Agreement Version 3, updated in June 2026, the amount usually depends on the company’s stage and the advisor’s expected involvement.

Typical ranges include:

• Pre-seed: 0.25% to 1.00%
• Seed: 0.25% to 0.75%
• Series A: 0.10% to 0.50%

In most situations, a single advisor should not require more than 1% of the company’s equity.

The appropriate amount should reflect the value of the advisor’s ongoing contribution rather than their reputation alone.

Advisor Equity Should Always Vest

Unlike founders, advisors usually contribute over time rather than making a long-term operational commitment.

For that reason, advisor equity should generally vest over approximately two years, often with monthly vesting and a short cliff.

Vesting ensures advisors earn equity only while they continue providing meaningful assistance.

If an advisor stops participating shortly after joining, unvested equity remains with the company instead of becoming dead equity on the capitalization table.

Put Every Advisor Relationship in Writing

A verbal agreement is rarely enough. A properly drafted advisor agreement should clearly address:

• The advisor’s responsibilities and expected level of involvement.
• The vesting schedule.
• Intellectual property assignment.
• How either party may terminate the relationship.

Clearly documenting these terms helps avoid misunderstandings and provides investors with confidence that the company’s equity grants have been properly managed.

Intellectual Property Should Belong to the Company

Some advisors contribute more than introductions or strategic advice. They may help create product concepts, marketing materials, business presentations, and technical documentation.

Without an appropriate intellectual property assignment, ownership of these materials may remain uncertain.

Including an IP assignment clause ensures that work created as part of the advisory relationship belongs to the company.

Match the Equity Grant to the Actual Contribution

Not every advisor provides the same level of involvement.

Some advisors participate in recruiting, customer introductions, fundraising preparation, and regular strategy sessions.

Others simply make occasional introductions or attend quarterly meetings.

The equity grant should reflect both the company’s stage and the advisor’s expected workload and ongoing contribution.

Paying for measurable contributions rather than perceived prestige helps preserve founder ownership while rewarding advisors fairly.

Review Advisor Equity Before Every Fundraising Round

Advisor grants often receive closer attention during investor due diligence. Investors may review the size of each advisor grant, vesting schedules, written agreements, and intellectual property assignments.

Keeping advisor arrangements well documented reduces unnecessary questions during fundraising and demonstrates disciplined equity management.

Founders who regularly review outstanding advisor grants are also less likely to accumulate inactive advisors holding significant ownership.

Common Founder Mistakes

• Promising advisor equity without a written agreement: Handshake arrangements often lead to disagreements about ownership, responsibilities, and vesting when the company begins fundraising.
• Granting more equity than the advisor’s contribution justifies: Well-known advisors do not automatically deserve 2% or 3% ownership. Equity should reflect the company’s stage and the advisor’s actual involvement.
• Issuing advisor equity without vesting: Advisors who stop contributing early should not continue holding unearned ownership in the company.
• Leaving intellectual property ownership undefined: If an advisor creates presentations, software, product ideas, or other valuable materials, the agreement should clearly assign those rights to the company.

10-Minute Advisor Equity Self Check

• Have I benchmarked the proposed grant against current market ranges?
• Does the advisor’s equity vest over approximately two years?
• Have both parties signed a written advisor agreement?
• Does the agreement clearly define the advisor’s responsibilities?
• Does it include an intellectual property assignment?
• Would I feel comfortable explaining this equity grant during investor due diligence?

If you cannot answer yes to all of these, you are not ready to grant advisor equity yet.

Bottom Line

Advisor equity can be a valuable tool for attracting experienced mentors, but it should always be structured carefully. Reasonable equity grants, vesting schedules, written agreements, and intellectual property assignments help protect the company’s cap table while ensuring advisors are rewarded for meaningful, ongoing contributions rather than informal promises.
