TL;DR: If you are giving a member of your advisory board equity, you should also sign an Advisor Agreement (sometimes called an Advisor Letter) between the advisor and your startup. It protects your company, clarifies expectations, and closes the two biggest gaps: confidentiality and intellectual property.
Why an Advisor Agreement matters when you grant advisor equity
Once you start paying an advisor in equity, you are not just being generous. You are creating an ongoing relationship where the advisor may get access to sensitive information and may influence product or strategy.
An Advisor Agreement is the basic document that keeps that relationship clean. It is also the easiest way to avoid misunderstandings later about what the advisor is doing and what they are getting in return.
What an Advisor Agreement is (and what it is not)
An Advisor Agreement defines the startup-advisor relationship and the guardrails around it.
A typical Advisor Agreement covers:
The advisor’s role and scope (what they are actually doing)
The equity being granted and the form of equity (options or restricted stock)
The vesting schedule and any service expectations tied to vesting
Important: an Advisor Agreement is usually not a substitute for the actual equity paperwork. If you are issuing options or restricted stock, you still need the applicable option or stock grant documents.
Confidentiality is usually non-negotiable
If you want an advisor to be useful, you will likely share confidential information. That can include product roadmaps, customer plans, fundraising strategy, and technical details.
A confidentiality clause sets the baseline expectation that the advisor:
Will not disclose your confidential information
Will not use it for any purpose other than advising your company
In most deals, confidentiality is a hard requirement. The only point that sometimes gets negotiated is duration. If a prospective advisor will not agree to confidentiality at all, that is a strong signal to move on.
Consider an IP assignment clause in the advisor agreement, but right-size it for advisors
The other big issue is intellectual property. With employees, you generally want a broad inventions assignment. With advisors, the right answer is often narrower.
The advisor is deeply involved in product or technical development
The advisor will be working with confidential technology
The advisor is creating materials, designs, code, or other work product
It may be unnecessary, or at least more limited, when:
The advisor’s role is high-level
The advisor is primarily making introductions
The advisor’s contributions are general feedback rather than creation
The more hands-on the advisor is, the more you should push for at least a light IP assignment that captures what they create for the company.
Term and termination: keep it simple
Most advisor relationships should be easy to end. Many advisor agreements allow either party to terminate at will, effective immediately.
Sometimes an advisor asks for a longer notice period. Before you agree, ask why. In a lot of cases, the real concern is economic, not emotional. The better fix is often in the equity grant terms (for example, how vesting works at termination), not in forcing a longer relationship.
Practical takeaway
If you are granting an advisor equity, treat the Advisor Agreement as part of the equity grant, not an optional extra. It is how you protect confidentiality, handle IP cleanly, and make sure both sides agree on what the relationship is supposed to be.
If you remember one thing: grant advisor equity only when the expectations and protections are written down.
FAQs
Do I need an Advisor Agreement if I give an advisor equity?
Usually yes. Equity plus access to sensitive information is exactly when you want the relationship defined in writing, including confidentiality and IP terms.
Is an Advisor Agreement the same as an option grant agreement?
No. The Advisor Agreement governs the relationship. The option grant agreement or stock grant agreement governs the equity instrument itself.
Should my Advisor Agreement include inventions assignment?
Often yes, but usually narrower than an employee inventions assignment. It depends on how involved the advisor is with product development and confidential technology.
Can either side terminate an Advisor Agreement immediately?
Often yes. At-will termination is common, and if someone wants a long notice period, it is worth understanding what problem they are trying to solve.
