A fractional COO we know recently accepted 0.75% in options over a three-year vest from a Series A SaaS company in exchange for a 20% discount on her monthly retainer. Eighteen months in, the company raised a down round, her options went underwater, and the new lead investor pushed for a repricing that excluded fractional grants. She walked away with nothing to show for the cash she had left on the table. Her next engagement, at a later-stage marketplace company, she asked for 0.3% with accelerated vesting on a change of control and no cash discount. That company exited two years later. She cleared mid-six figures.
Both decisions looked reasonable on paper at the time. The difference came down to three things: how she evaluated the company, how she structured the grant, and what she was willing to walk away from. This guide is what we wish every fractional executive read before their first equity conversation.
When Equity Makes Sense
Equity conversations should start from a clear-eyed view of what equity is: a lottery ticket with specific odds. Our marketplace data across 400-plus fractional engagements suggests about one in eight equity grants at seed stage produces a meaningful payout. At Series A, the ratio improves to roughly one in five. At Series B and later, it approaches one in three, but the grant sizes drop.
Equity makes sense when three conditions are true. First, the company has institutional venture investors who have done their own diligence. Second, you have a cash floor below which the engagement no longer covers your opportunity cost. Third, the equity is structured through the company’s formal option plan with a recent 409A, not improvised on a handshake.
Equity does not make sense when the company is bootstrapped with no exit intent, when the founders are using equity to avoid paying market rates, or when the engagement is genuinely short-term (under six months). In those cases, cash-only is the correct answer.
Equity Structures You Will Encounter
ISOs and NSOs Through the Option Plan
The cleanest structure is a standard option grant through the company’s 2022 or 2024 Equity Incentive Plan. You receive the right to buy a number of shares at the current 409A strike price, typically vesting over four years with a one-year cliff. As a non-employee, you will generally receive NSOs rather than ISOs, which has tax implications at exercise.
Grant sizes for fractional executives typically range from 0.1% to 1.0% of fully diluted shares. At seed stage, a fractional CMO or CFO might see 0.5%-1.0%. At Series A, 0.25%-0.5% is typical. At Series B and later, 0.1%-0.25%. Adjust based on scope: a 0.5 FTE engagement warrants more than 10 hours a week.
Advisor Shares via an FAST or Similar Framework
The Founder/Advisor Standard Template (FAST) is common for pure advisory relationships. It specifies grant sizes by stage and advisor tier, typically 0.1%-1.0% vesting over two years with no cliff. FAST works for light-touch advisory (monthly calls, ad hoc introductions) but is usually inappropriate for an embedded fractional executive doing real operational work.
If a founder offers you FAST-tier equity for a 15-hour-a-week fractional role, push back. You are operating, not advising, and the grant size and structure should reflect that.
Profit-Share or Revenue-Share Arrangements
For bootstrapped companies without an exit path, some fractionals negotiate a profit-share or revenue-share kicker on top of a base retainer. Common structures: 2%-5% of net new revenue attributable to your work, or 5%-10% of distributable profit above a threshold. These arrangements require rigorous tracking in a tool like ProfitBooks so both parties agree on the underlying numbers. Without clean books, profit-share conversations turn into disputes.
Phantom Equity and SARs
Some privately-held companies that do not want to issue real stock use phantom equity or stock appreciation rights. These pay out in cash at a triggering event (usually a sale) based on the appreciation in share value. The tax treatment is ordinary income, not capital gains, which is meaningfully worse than a qualified option. Only accept phantom equity if the cash component of the engagement is strong and you are treating the phantom piece as a true bonus, not core compensation.
The Valuation Questions You Must Ask
Before agreeing to any equity structure, you need to understand what you are being offered. These questions are non-negotiable:
- What is the current 409A valuation, and when was it last refreshed? If the answer is “we have not done one” or “it is over 12 months old,” that is a problem. Options granted off a stale 409A can create tax liability for you.
- What is the total fully diluted share count, including the unissued option pool? Percentage-only offers (“we will give you 0.5%”) are meaningless without this number.
- What is the most recent preferred round valuation, and what were the terms? A $50M post with a 2x liquidation preference is a very different company than a $50M post with a 1x non-participating preference.
- What is your cash runway, and what is the hiring plan? A company that will need to raise again in six months at a flat or down round will dilute your stake substantially.
- What does the cap table look like? Who owns what? You do not need share counts, but you need to know if the company is founder-controlled or investor-controlled, and whether the common stock is meaningfully diluted.
If the founder or CEO cannot answer these questions in a single 30-minute conversation, the company is not ready to grant equity to outside operators.
Vesting Terms That Protect You
Standard vesting for fractional executives is two to four years with a three-month to one-year cliff. Match the vesting to your realistic engagement horizon. If you typically run 12-month engagements, a four-year vest with a one-year cliff means you are likely to leave with 25% of your grant. That may be fine, but price the engagement accordingly.
Two vesting terms worth negotiating:
- Acceleration on change of control. Double-trigger acceleration (vesting accelerates if the company is acquired AND your engagement is terminated without cause) is standard and should be in your grant.
- Acceleration on termination without cause. Less standard but reasonable for fractionals. If the company terminates you without cause before you are fully vested, some portion of unvested equity should accelerate. Three to six months of additional vesting is a common compromise.
The 83(b) Election (Do Not Skip This)
If you receive restricted stock (not options) with vesting conditions, you have 30 days from the grant date to file an 83(b) election with the IRS. The election taxes you on the value of the stock at grant (usually low) rather than at each vesting date (when the value may be higher). Missing this 30-day window can cost you five to six figures in ordinary income tax on the vesting spread.
For options (ISOs and NSOs), 83(b) elections apply only if you early-exercise unvested options. Most fractionals do not early-exercise. If you do, work with a tax advisor and file the election.
Common Mistakes Fractional Executives Make
Accepting “we’ll figure it out later.” Equity promises without a signed grant agreement are worth nothing. If the company cannot formalize the grant within 60 days of your engagement start, assume it will never happen and renegotiate cash terms.
Taking equity in place of cash to “help the founder.” Founders who cannot pay market cash rates usually cannot pay the team, the rent, or the legal bills either. Equity does not fix a broken business. It just transfers the risk to you.
Ignoring the tax consequences at exercise. NSOs create ordinary income tax liability at exercise based on the spread between strike price and FMV. If you exercise $200,000 worth of NSOs, you owe income tax on that spread the year you exercise, even if you cannot sell the shares. Plan for this.
Not tracking vesting or grant documents. Keep a personal record of every grant agreement, vesting schedule, and 409A valuation update. When the company is acquired or goes public two to five years later, you will need these documents. Companies change CFOs and cap table managers. Your records are your own backup.
Walking into a down-round grant without repricing protection. If the company does a significantly dilutive down round, your unvested equity gets crushed. Some grant agreements include repricing protection; most do not. Ask.
When to Walk
Walk from an equity conversation when:
- The founder cannot articulate a credible path to an exit or a cash-generating event within five years.
- The grant is being offered in lieu of cash below your sustainable rate.
- The company has not done a 409A and is granting options at a made-up strike price.
- The other investors on the cap table have liquidation preferences so large that the common stock is mathematically unlikely to see proceeds.
- The engagement scope and hours keep expanding while the equity and cash stay fixed.
Walking from a bad equity deal is not the same as walking from the engagement. You can often keep the cash relationship and decline the equity, or take a smaller equity grant with cleaner terms.
A Real Equity Negotiation Scenario
A fractional CFO was offered a Series A engagement: $9,000/month plus 0.4% in NSOs, four-year vest, one-year cliff. Post-money valuation $45M, clean preferred stack, solid investors. He asked three questions before accepting. One: what is the 409A strike price? Answer: $1.20, refreshed two months earlier. Two: is there double-trigger acceleration on change of control? Answer: no, but we will add it. Three: if I exit the engagement at month 18 in good standing, what happens to the unvested half of the grant? Answer: it returns to the pool. He countered with a request for six months of acceleration on termination without cause. The company agreed. He took the engagement. Eighteen months later he transitioned out in good standing with 50% vested (the standard 18-month portion) plus six months of acceleration, totaling roughly 24 months of vesting on a 48-month grant.

FAQ
Is 0.5% a lot of equity for a fractional executive?
At seed stage, it is typical for an embedded fractional executive working 15-plus hours a week. At Series A, 0.5% is on the higher end. At Series B and beyond, 0.5% is unusual and probably means the cash is light.
Can I negotiate equity on top of my standard retainer?
Yes, and you should frame it that way. Equity is additional compensation for sustained engagement and aligned outcomes, not a discount on cash.
What happens to my equity if the company is acquired before I vest?
Depends on your grant agreement. With double-trigger acceleration, your unvested equity vests if you are terminated in connection with the acquisition. Without it, unvested shares typically convert to options in the acquirer or are cancelled.
Do I need a lawyer to review my equity grant?
For grants over 0.25% at a venture-backed company, yes. Budget $500-$1,500 for a one-time review. For smaller grants or clear standard-form documents, a careful self-review is usually sufficient.
Can I take equity as an LLC rather than as an individual?
Sometimes, but most companies will only grant equity to individuals because of option plan restrictions. If you have an LLC for your fractional practice, plan to receive equity personally and manage the cash side through the LLC.
What if the company is bootstrapped and profitable?
Equity is a weaker fit because there is no exit event to monetize shares. Negotiate a profit-share or revenue-share kicker instead, and track the underlying numbers rigorously.
