A seed investor is going to want 15 to 25 percent of your top line. Not your profits. Your revenue, off the top, before rent, before your analyst, before you.
It is an easy line to nod past. You are a few months from launch, someone is finally offering real capital, and 20 percent of something beats 100 percent of a fund you have not raised yet. That math is fair. The catch is that the number does not really land until year three, when the fund is working and the fees are real and you find yourself wiring what feels like a small fortune to someone whose check cleared exactly once, back when you needed it.
None of which makes it a bad deal. For most emerging managers it is the door that actually opens, and a good seed can be one of the better trades a manager makes. The point of this piece is narrower: to state the actual ranges plainly, with sources, so a manager is reading the fine print with roughly the same fluency the person across the table already has.
So how much of the firm are they really taking?
There are two numbers, and they bite at different moments. The revenue share is the one felt every quarter. The ownership stake in the management company is the one felt the day a manager tries to leave, sell, or bring in a partner.
A seeder commonly takes a 10 to 25 percent economic interest in the management company, according to GCM Grosvenor's 2023 overview of the GP-seeding market, and a revenue share that, per Tannenbaum Helpern, tends to sit in that same 15 to 25 percent band of gross revenue, frequently with a percentage of the carried interest and of any sale or IPO proceeds layered on top. Where a deal lands inside those ranges tends to come down to three things: how much capital is being committed, how real the manager's track record is, and how much each side needs the other that particular quarter.
What it does not come down to is a single formula, because there is not one. Anyone who quotes a manager a "market" rate to the decimal is quoting their own last deal and calling it the weather.
Why almost nobody takes actual equity
Here is the structural fact that rarely gets stated in plain language, and it quietly shapes everything else in the deal.
Across the 2014 to 2018 period tracked by the Seward & Kissel Seed Transactions Deal Points Study, the special limited partner (revenue-share) structure accounted for 90 to 96 percent of observed seed deals year by year, with 94 percent in the 2018 sample specifically. True equity showed up in the remainder. Seward & Kissel's own analysis frames the choice as a threshold question in every deal: a top-line revenue share versus a bottom-line equity interest, and notes that the revenue-share structure "remains the overwhelmingly preferred means of structuring seed economics."
Why do seeders prefer it this way? A revenue share is comparatively easy to value, and easier to unwind when the buyout eventually comes. Direct equity drags governance, tax treatment, and control questions into what the seeder would rather keep as a clean financial arrangement. The special-LP structure hands the seeder the economics of ownership without most of the entanglements. Once that incentive is visible, the rest of the standard terms, the lockup, the buyout pricing, stop looking arbitrary.
The lockup, and what it is really for
Historically, the market standard was a two-year hard lockup on the seeder's capital, one-year locks the exception and three-year-plus locks rarer still, according to Seward & Kissel's 2014 to 2018 data. That baseline is moving: the firm's 2023 Seed Transactions Deal Points Study, its tenth annual edition, found three-year lockups in half of the deals it observed that year, up from roughly 10 percent in 2018, alongside a rise in working capital support to more than three-quarters of deals, up from 48 percent in 2018. A manager negotiating today should ask which figure the other side is actually quoting and confirm it against the current-year study rather than assume the older two-year figure still holds.
The lockup is not a compliment, and it is not really a statement of confidence in the manager. It is the seeder protecting the thing it is paying for, which is the fund's launch AUM. Seed capital is what lets a manager walk into the next allocator's office and say the fund manages real money. If the seeder could leave early, that sentence falls apart, and so does the value of what was bought. There is usually a release valve, though: in the 2014 to 2018 data, most drawdown-triggered early releases used a threshold of 15 percent or less. That is the clause worth reading twice, because it is the one that matters in a bad year.
Deal structures compared
| Structure | What the provider takes | Who bears first loss | Typical stage |
|---|---|---|---|
| Revenue share / special LP interest | 15–25% of gross management-company revenue, often plus a slice of carry | The manager, on the underlying fund's trading losses | Day-one launch capital, the overwhelming majority of seed deals |
| True equity in the management company | A direct ownership stake, typically 10–25%, with governance and information rights | The manager, though the equity holder shares in operating losses too | Uncommon at seed; more typical of established-firm GP-stakes deals |
| First-loss capital | A fee on the capital provided plus the minority of trading profits; the manager keeps an elevated share, commonly cited in the 50–80% range | The manager, via a personal first-loss deposit (commonly around 10% of the allocation) that absorbs losses before the provider's capital is touched | Capacity-building for a manager who already has a launched track record |
The manager's elevated profit share in first-loss structures is reported across a wide range depending on the platform, most often between 50 and 80 percent of trading profits, in exchange for posting the first-loss deposit. Treat that range as illustrative rather than a fixed market rate; it is more variable deal to deal than the revenue-share figures above.
Can a manager buy the seeder out? Yes, and here is the arithmetic
This is the part worth understanding before signing, not after the fund is running.
The most common formulaic buyout price in the Seward & Kissel data is five times the trailing 12, 24, or 36 months of payments to the seeder, with four times the next most frequent multiple observed. Some deals price the buyout off assets instead. One detail worth knowing: an explicit buyout right appears in fewer than half of seed deals in the observed data, down from roughly two-thirds earlier in the same period. A manager who wants the option to eventually own the firm outright needs to negotiate that right at the start. It does not come standard.
It is worth doing the arithmetic before celebrating a signed term sheet. A 20 percent revenue share on a management company generating a few million dollars a year, bought out at five times trailing payments, is a serious check. That is not a reason to pass on the deal. It is a reason to know the exit price on the day it is signed.
What is actually up for negotiation
The ranges above are wide on purpose, and inside them a manager with a real track record and a little competitive tension has room to move. The terms most worth spending negotiating leverage on:
- Where the deal lands in the revenue-share band. The gap between 15 and 25 percent is income for the life of the deal. It is not a rounding error.
- A defined buyout right, and the multiple attached to it. Without one, owning the firm outright someday is not on the menu later at any price.
- Sunset or step-down provisions. Roughly 20 to 30 percent of deals in the Seward & Kissel data include a schedule where the seeder's economics fade or end after a set period. That clause can be worth more than a better headline percentage.
- The drawdown release threshold. Set it higher, and the seeder cannot exit in the exact year the fund most needs the capital to stay in place.
A manager will not get all four. It is worth deciding which two matter most before the meeting, since the party across the table settled that question a long time ago.
Frequently Asked Questions
How much of my management company does a seed investor take?
Commonly a 10 to 25 percent economic interest in the management company, per GCM Grosvenor, plus a 15 to 25 percent share of gross revenue and often a slice of carried interest, per Tannenbaum Helpern. The exact figure tracks the size of the seeder's commitment and the strength of the manager's track record.
Is a seed deal a percentage of profit or revenue?
Revenue. The share comes off the management company's top line, before expenses, which is why it tends to feel larger in practice than managers expect going in.
How long is the lockup?
Two years was the long-standing market standard, usually a hard lock, often with an early-release trigger around a 15 percent drawdown. Seward & Kissel's 2023 study found three-year lockups had grown to half of observed deals, up sharply from 2018. Confirm the current figure before relying on either number.
Can I buy my seed investor out later?
Usually, if the right was negotiated at signing. The common formulaic price is about five times the trailing 12 to 36 months of payments. Fewer than half of deals in the observed data include an explicit buyout right, so it is worth asking for one up front rather than assuming it is standard.
Revenue share or equity, which will a manager be offered?
Almost certainly a revenue share through a special limited partner interest. True equity showed up in under 10 percent of seed deals in the 2014 to 2018 Seward & Kissel data, largely because the revenue-share structure is easier for the seeder to value and to exit.
What happens if the fund has a bad year during the lockup?
Most seed agreements include an early-release trigger tied to a drawdown, commonly in the 15 to 20 percent range, that lets the seeder redeem before the lockup ends. This is a negotiated term, not a given, and it is worth reading before the fund has a bad year, not after.

A note on scope: the ranges above describe broad market practice as reported in third-party industry research, not terms offered by any specific seeder, including Whitespace. Actual deal terms are negotiated individually and can fall outside these ranges in either direction depending on the manager, the strategy, and market conditions at the time.
Whitespace works with emerging hedge fund and private equity managers on day-one capital and the LP relationships that come with it. If a fund is at the stage where these questions stop being theoretical, the next step is a conversation, terms are discussed case by case and are not set by the ranges in this piece.
