The Advisor Agreement Startup Founders Get Wrong (and the Four Terms That Fix It)

An advisor takes 0.5 percent of your company, shows up to a single call, then disappears, and the fix is one line you forgot to write.

Good advisors are worth real equity. A poorly structured advisor deal, though, can quietly cost you a meaningful slice of your company for almost nothing in return. The difference usually comes down to the advisor agreement startup founders sign at the very start of the relationship, before anyone has thought carefully about what the arrangement should actually require. The encouraging part is that this contract stays short, typically running one to three pages. Most founders reach for the FAST agreement, short for Founder/Advisor Standard Template, because that free standard form from the Founder Institute covers the essentials without expensive customization. Even so, the form only protects you when four terms are set correctly: scope, equity grant, vesting, and IP. Miss any one of them and you can hand equity to someone who stops showing up. Get all four right and you gain aligned, motivated help precisely when you need it most. In this guide, you will learn exactly what each of those four terms should say, so your next advisor deal works for you instead of against you.

Scope: the part of the advisor agreement startup founders skip

Most founders write the equity number first and the scope last, which is exactly backwards. Scope is what you should pin down before anything else. It simply means what the advisor actually does for you, so spell it out in concrete terms: how many hours a month they commit, what kind of meetings you expect, whether in person, on video, or in quick async messages, and which areas of expertise they cover. This matters more than it first appears, because vague scope reliably produces vague advice. A line like "general guidance" gives you nothing to hold an advisor to, whereas a specific scope produces useful advice and a clear bar to measure performance against. The FAST agreement helps here, since it offers scope tiers (Standard, Strategic, and Expert) that map to defined time commitments, which lets you pick the tier that matches the help you actually need. When the scope is written clearly, the rest of the startup advisor contract has something solid to stand on. The relationship benefits too, because a clear scope means the advisor understands what you expect and you understand what to ask for, so nobody feels overused and nobody feels ignored. That mutual clarity is what keeps a strong advisor engaged well past the first few months, and it is why scope sits at the top of any advisor agreement startup founders take seriously.

Equity and vesting: how to grant advisor equity without giving it away

Now for the number everyone obsesses over: how much advisor equity is actually fair. For most early-stage startups, the range runs from 0.1 to 1.0 percent of fully diluted equity, and the exact figure depends on how early your company is and how senior the advisor is. A well-known operator who opens doors should earn more than a friendly mentor who answers the occasional text. The grant size, though, is not the part that protects you. Vesting is. Vesting means the advisor earns their equity gradually over time rather than all at once, and the standard advisor vesting schedule runs two years with no cliff, paid out in monthly slices. That works out to roughly one twenty-fourth of the grant for each month they stay engaged. Here is the trap worth avoiding: without vesting, an advisor who ghosts you after a single call still keeps the full grant, whereas with vesting they only keep what they actually earned. That one clause is the difference between a fair deal and a slow leak in your cap table. It also keeps the advisor motivated, because their equity grows each month they remain useful, which gives them a real reason to keep answering your calls a year in. So skip it and you are betting your equity on someone's good intentions. Add it, and the math takes care of itself.

IP and confidentiality: protect what the advisor sees

Your advisor will see things outsiders never do, including your strategy, your roadmap, and your hiring plans. Sometimes they even help create company IP through product direction or a key introduction. Because of that exposure, the agreement has to cover two things carefully. The first is IP assignment, which means any intellectual property the advisor creates while working for you should belong to the company rather than to them, so you never face a former advisor claiming they own an idea you built on. The second is confidentiality, where the advisor's duty to protect your secrets should survive the engagement, so that even after they stop advising they still cannot share what they learned. The standard FAST language covers both of these cleanly, which is one more reason it remains the default form for the advisor agreement startup teams reach for. The bottom line is straightforward. Scope, equity, vesting, and IP are the four terms that decide whether the deal protects you, and getting all four right is what keeps a generous grant from becoming a regret.
