Startup Equity for Advisors and Contractors

Offering equity to an advisor or a contractor can feel like a cheap way to get help you could never afford in cash. It is not cheap. Every share you hand out is a slice of the company you are building, and a loose promise made over coffee can turn into a messy dispute at your next funding round. This guide shows you how to decide whether equity is the right currency, how to structure it, and how to write it down so everyone stays happy.

Key takeaways

Give equity to advisors and contractors only when you can name the specific outcome you expect from them.
Use vesting for everyone. Shorter schedules and milestone vesting often suit advisors and contractors better than a standard employee schedule.
The type of grant matters: options, restricted stock and phantom arrangements carry different tax and admin consequences in the US and UK.
Put every grant in a signed agreement, approve it at board level and record it on your cap table the same week.

Early-stage founders meet a lot of generous people: a former executive who offers to open doors, an engineer who will build an integration for a lower rate, a designer who wants "a bit of the upside." These can be great deals. The fix for the risks is not to avoid equity, but to treat each grant as a small decision with a clear purpose, structure and record. Before we start: this article is general information about equity, tax and contracts, not legal, tax or financial advice. Rules differ by country and change over time, so work with a startup lawyer and an accountant before you issue anything.

When equity makes sense for advisors and contractors

Equity is the most expensive thing you own, because its value grows with every milestone you hit. Use it when cash is genuinely scarce and the person's contribution will still matter in two or three years.

Good reasons to offer equity

Long-term commitment. An advisor who will join monthly calls, review your product roadmap and make introductions for the next two years.
Hard-to-hire expertise. A regulatory specialist, a security architect or an industry insider whose time you could not otherwise afford.
Alignment on outcomes. A contractor building a core system who benefits when the product succeeds, not just when the invoice is paid.

Weak reasons to offer equity

You want a well-known name on your website but cannot say what they will actually do.
You are trying to avoid an uncomfortable conversation about rates.
The work is a one-off project, such as a logo or a short audit, with no ongoing role.

For one-off work, cash is usually cleaner.

Pro tip

Before you offer any equity, write one sentence that starts with "By this time next year, this person will have helped us..." If you cannot finish the sentence with something specific, you are not ready to make a grant.

Choosing the right type of grant

Advisors and contractors are not employees, and that changes which instruments are available and how they are taxed. Here is the landscape in plain language.

In the US: options, restricted stock and their tax quirks

US startups generally use two kinds of stock options. Incentive stock options (ISOs) can carry tax advantages but are generally reserved for employees. Non-qualified stock options (NSOs) are more flexible and are the usual route for advisors, contractors and board members. Options are typically priced at fair market value, which most startups set using a 409A valuation. Exercising options and paying tax on them can be complex, so the holder should get their own tax advice.

Some very early companies grant restricted stock instead of options, especially before a priced round when the share value is still low. If the stock vests over time, the recipient may want to file an 83(b) election with the IRS. That election must be made within 30 days of receiving the restricted stock, and missing it cannot be fixed later. Make sure anyone receiving restricted stock knows the deadline and talks to a tax professional.

In the UK: EMI and the alternatives

Enterprise Management Incentive (EMI) options are the main tax-advantaged scheme for small UK companies, but they are designed for employees who meet working-time conditions. Most advisors and independent contractors will not qualify. UK startups often use unapproved options or growth shares for non-employees instead. Each has its own tax treatment, so this is an area where a UK share scheme adviser earns their fee.

Phantom equity

Some companies share upside without adding anyone to the cap table, through phantom equity: a cash payment tied to a future exit. It is still a real obligation and needs careful drafting.

Common mistake

Promising "1% of the company" in an email or chat message. A percentage is meaningless without a share count, a date, a grant type and a vesting schedule, and it shrinks with every funding round. Always talk in a specific number of shares or options, and explain that dilution will reduce the percentage over time.

Vesting that matches the relationship

Vesting protects both sides. The person earns their equity as they contribute, and the company does not end up with large blocks of shares held by people who stopped helping long ago.

For founders and employees, a common pattern is four years of vesting with a one-year cliff. That is a rule of thumb, not a law, and it is often too long for advisors and contractors. Many companies use shorter schedules for these roles, such as monthly vesting over one to two years, sometimes with a short cliff of a few months so a relationship that never gets going does not leave shares behind.

Time-based vesting

Time-based vesting suits advisors whose value comes from steady availability: monthly calls, quick answers and introductions.

Milestone-based vesting

Milestone vesting suits contractors whose value comes from delivering something specific. For example, a portion vests when an integration goes live, another when it passes a security review, and the rest when it has run in production for a set period. Write each milestone so a neutral person could tell whether it happened. "Make the app faster" is a recipe for disagreement. "Page load under the agreed target on the agreed test" is not.

What happens on an acquisition

Decide early whether any unvested equity accelerates if the company is sold. Advisors sometimes ask for full acceleration on a sale. Founders and investors often prefer limited or no acceleration. There is no single right answer, but there should be a written one.

How to size a grant without guessing

You will find plenty of opinions about "standard" advisor percentages online. Treat them with caution. The right size depends on your stage, your fully diluted share count, the person's expected time and what you could pay in cash instead. A fairer approach is to work from value and time.

Estimate the cash value of the work. What would you pay this person per month at their normal rate, and for how many months?
Decide the cash and equity split. Many contractors take part cash, part equity. Agree the share each side carries.
Use your current share price. For options, this is usually the 409A or latest fair market value. For a UK company, use the most recent valuation your adviser agrees is appropriate.
Translate value into a share count. Divide the equity portion of the value by the current price per share to get a starting number.
Sense-check against your fully diluted total. Fully diluted shares count issued shares plus options, warrants, the unissued option pool and shares from convertible instruments on an as-converted basis. See what percentage the grant represents on that basis.
Compare with your other grants. An advisor who joins one call a month should not receive more than a senior early employee. Consistency protects trust inside the team.

Hypothetical example

Priya runs a two-person health software startup. She needs a part-time security architect for about six months and cannot afford the full day rate. Using made-up numbers, she agrees to pay half the rate in cash and the other half in NSOs, valued at the company's current fair market value per share. The options vest in three tranches: one when the security design is approved, one when the first enterprise customer passes its vendor review and one after the system has run for three months without a major incident. Everything sits in a signed advisor and contractor agreement, approved by her board the same week.

Contractor, security	NSO	15,000 options	3 milestones	Security design approved, first vendor review passed	Example: 14 Jan	Yes
Contractor, UK designer	Unapproved option	8,000 options	Monthly over 12 months	Design system and onboarding screens	Example: 2 Feb	Pending

Add exercise price and expiry columns once agreements are drafted.

Paperwork that keeps everyone protected

Equity without documents is just a promise, and promises are hard to enforce in either direction. Make sure every advisor and contractor grant includes the following.

A written agreement. An advisor agreement or contractor services agreement that describes the role, the time commitment, the equity terms and how either side can end the arrangement.
IP assignment. Anything the person creates for your company should belong to the company. Investors will look for this in your data room alongside contracts and employment agreements.
Board approval. Most grants need formal approval from the board or shareholders, depending on your company documents. Record it in the minutes.
Cap table update. Add the grant the same week so your records never drift from reality.
Grant notice or option agreement. The formal document showing the number, price, vesting and expiry.

Contract management tools such as PandaDoc, Juro, Ironclad or DocuSign can help you send, sign and store these agreements in one place. Check each tool's current features, pricing and privacy policies before you choose, and always have a lawyer approve the underlying templates.

Managing the relationship after the grant

The grant is the start, not the finish. A short routine keeps the arrangement healthy.

Quarterly check-ins. Review what the advisor or contractor delivered against the expected outcome. If they are not delivering, raise it early and kindly.
Milestone sign-offs. When a milestone is reached, confirm it in writing and update your records.
Clean exits. If the relationship ends, confirm in writing how much has vested, what happens to the unvested portion and how long any vested options remain exercisable.
Year-end review. December is a natural moment to tidy records before investors ask for updated numbers in the new year. Check each grant, each agreement and each signature.

Frequently asked questions

Should advisors get equity from the employee option pool?

Many startups grant advisor equity from the same option pool, which keeps it visible in the fully diluted share count. Some set aside a separate allocation. Either way, track it carefully so you do not run out of room for future hires.

Can a contractor receive ISOs in the US?

ISOs are generally limited to employees, so contractors and independent advisors usually receive NSOs or restricted stock instead. Confirm the details with a US tax adviser before granting.

What if an advisor stops helping after a few months?

This is exactly why vesting exists. If the agreement includes a cliff and the relationship ends before it, no equity vests. After the cliff, only the vested portion stays with the person, and you can end the arrangement under the notice terms in your agreement.

Do I need a valuation before granting options?

In the US, options are usually priced at fair market value based on a 409A valuation, which helps avoid tax problems for the holder. In the UK, share schemes often rely on an agreed valuation too. Ask your adviser what applies before you set any price.

The bottom line

Equity can bring brilliant people into your startup long before you can pay them properly, but only if every grant has a purpose, a structure and a paper trail. Name the outcome, pick the right instrument, vest it sensibly and write it all down. Then review each relationship regularly so equity stays tied to real contribution.
