A seed round term sheet is a short document that sets out the economic deal and governance rules for a startup’s first priced fundraise. Most of its provisions are non-binding statements of intent, but the exclusivity and confidentiality sections typically bind both sides the moment they sign. Its real purpose is to pin down valuation, preferences, board control, and vesting so counsel can draft the definitive agreements without reopening every point.
Before negotiating one, confirm you actually need one. The instrument you use for a seed raise determines whether a full term sheet is even on the table.
When a Term Sheet Applies
A priced equity round is the structured path. The company issues preferred stock at a fixed price per share, and the term sheet covers valuation, liquidation preference, board seats, protective provisions, and the rest of what follows. Legal fees for a priced seed round using the standard NVCA model documents typically run $15,000 to $45,000 on the company side alone.
A SAFE (simple agreement for future equity), created by Y Combinator, is the dominant instrument for early seed fundraising and skips most of this. It is a one-page contract where the investor wires money now in exchange for equity later, when a priced round happens. There is no interest, no maturity, and usually a single negotiated term: the valuation cap. The current standard is the post-money SAFE, which lets both sides calculate exactly how much ownership has been sold immediately after signing.1Y Combinator. Safe Financing Documents
A convertible note is debt that converts into equity. It accrues interest (typically 4 to 8 percent annually) and carries a maturity date, usually 18 to 24 months out. If no priced round has closed by then, the note technically comes due. Both SAFEs and notes use a valuation cap, and sometimes a discount of 10 to 25 percent off the next round’s price, with whichever produces the lower conversion price controlling. If you issue multiple SAFEs before a priced round, early investors sometimes negotiate a most favored nation clause letting them adopt better terms offered to later SAFE holders.
The rest of this article assumes a priced seed round, because that is where the term sheet does its heaviest work.
Valuation and the Option Pool
Pre-money valuation is what the company is worth before the new investment lands. Post-money valuation is pre-money plus the cash coming in. A $1 million investment at a $4 million pre-money produces a $5 million post-money, and the investor owns 20 percent.
The option pool is where founders most often lose ground without realizing it. Investors almost always require the company to set aside shares for future employee equity grants before the deal closes. A typical seed-stage pool is 10 to 15 percent of fully diluted shares, sometimes as high as 20 percent. The critical detail: the pool is nearly always carved out of the pre-money valuation, meaning the dilution falls entirely on founders and existing shareholders rather than the new investor. The larger the required pool, the lower the effective price per share the founders receive, even when the headline pre-money number does not move. The pattern is known as the “option pool shuffle,” and it is one of the most negotiated points in any seed term sheet.
Push back on an oversized pool with a concrete hiring plan. If the plan calls for three engineers and a product lead before Series A, you have a real argument for 10 percent instead of 20. Every unnecessary percentage point comes directly out of founder ownership.
Liquidation Preference and Anti-Dilution
A liquidation preference determines who gets paid first in a sale, merger, or wind-down. The seed-stage standard is 1x non-participating: the investor gets their original investment back before common shareholders see anything, but they do not also take a share of the remaining proceeds on top of that. If the exit price is high enough, the investor converts to common instead, because their percentage of the full payout exceeds the guaranteed return. The 1x non-participating preference only really matters in modest exits where the payout is close to or below the amount invested.
Anti-dilution provisions protect investors if the company later issues shares at a lower price than they paid, a “down round.” The standard mechanism is broad-based weighted average anti-dilution, which adjusts the investor’s conversion price downward based on both the size of the down round and the price gap. A small down round produces a small adjustment; a large one produces a larger one. This is significantly more founder-friendly than full ratchet anti-dilution, which reprices the investor’s shares to the new low price regardless of how few shares were issued. Full ratchet is rare at seed and worth resisting hard.
Dividend provisions appear in most term sheets but rarely matter at this stage. They are typically non-cumulative, meaning dividends accrue only if the board declares them, which early-stage boards almost never do. Treat this as a placeholder, not a negotiation priority.
Founder Vesting and Acceleration
Investors will almost always require founders to vest their equity, even if the founders have been working on the company for years. The standard schedule is four years of vesting with a one-year cliff: no shares vest in the first twelve months, 25 percent vests on the cliff date, and the remainder vests monthly over the next 36 months. The point is to protect investors and remaining co-founders if someone walks away early.
If you have been building the company well before the seed round, the vesting start date is negotiable. Many investors will backdate it to the incorporation date or the date you started working full-time, giving credit for time already invested.
Acceleration clauses govern what happens to unvested shares in an acquisition. Single-trigger acceleration vests everything immediately upon a sale, which investors dislike because it removes the founder’s incentive to stay through a transition. Double-trigger acceleration is far more common: vesting accelerates only if the company is sold and the founder is involuntarily terminated (or constructively pushed out through a pay cut, forced relocation, or major demotion) within a set window after closing, typically 9 to 18 months. Some agreements add a short pre-closing window of around three months to prevent an acquirer from firing a founder right before the deal closes.
Board Seats and Protective Provisions
The term sheet defines who controls the board, which in turn controls major company decisions. A typical seed-stage board has three seats: two founder-appointed, one appointed by the lead investor. Founders keep majority control; the investor gets a seat at the table. Some term sheets add an independent director for a five-seat board (two founder, one investor, one independent, one mutually agreed), though that structure is more common at Series A.
Investors who want visibility without the fiduciary duties of a board seat sometimes take a board observer right instead. An observer can attend meetings and participate in discussions but cannot vote, and is not bound by the fiduciary duties directors owe the company as a whole. The trade-off is that observers can be excluded from confidential sessions dealing with litigation, conflicts, or similar matters.
Protective provisions give investors veto power over specific high-stakes actions regardless of board representation. Common triggers include selling the company, issuing new classes of stock, taking on significant debt, amending the charter, or increasing the option pool. These votes typically require approval from a majority of the preferred shareholders voting as a separate class. Watch the scope. A broad set of vetoes can give a minority investor effective control over company strategy even when they hold a single board seat.
Transfer and Follow-On Rights
Several provisions govern what happens when shareholders want to buy, sell, or transfer stock.
- Drag-along rights let a specified majority of shareholders (often holders of a majority of common and preferred voting together) force all remaining shareholders to participate in an approved sale, which prevents a small minority from blocking an exit most owners want.
- Tag-along rights let smaller investors sell on the same terms if a major shareholder sells to a third party, so founders or large holders cannot exit favorably while leaving minority investors behind.
- A right of first refusal gives the company and existing investors the chance to buy any shares a shareholder wants to sell to an outside buyer, on the same terms. Participation is typically pro rata, and investors who pass can usually have their shares absorbed by those who want more.
- Pro rata rights give seed investors the right (but not the obligation) to invest in future rounds to maintain their ownership percentage. For a seed investor, this is often the most valuable non-economic term in the deal.
The percentage thresholds on drag-along and tag-along rights matter more than founders sometimes realize. A drag triggered by a simple majority is far easier to invoke than one requiring two-thirds or three-quarters. Negotiate those numbers knowing the cap table will only grow more complex.
Information Rights
Priced seed investors typically require ongoing financial reporting, and the obligations survive long after signing. A standard package includes annual audited financial statements (due within 90 to 120 days of fiscal year-end), quarterly unaudited financials (within 45 days of quarter-end), and an annual budget and operating plan delivered at the start of each fiscal year. Some investors also negotiate monthly management reports covering revenue, burn, and headcount.
To keep the reporting burden from extending to every small check writer, companies set an ownership threshold (commonly 5 to 10 percent of preferred stock) that determines which investors qualify. Set that threshold carefully. A low number means reporting to a large group and more exposure of sensitive financials.
QSBS Status Under Section 1202
Section 1202 of the Internal Revenue Code lets investors in qualifying startups exclude up to 100 percent of the capital gain from selling the stock from federal income tax, provided they hold the stock at least five years. The exclusion is capped. For stock acquired after the statute’s most recent amendments, the per-issuer cap is $15 million or ten times the investor’s adjusted basis in the stock, whichever is greater.2Office of the Law Revision Counsel. 26 USC 1202 – Partial Exclusion for Gain From Certain Small Business Stock
Eligibility has conditions worth verifying before anyone relies on the benefit. The company must be a domestic C corporation with aggregate gross assets of no more than $75 million at the time the stock is issued. The stock must be acquired at original issuance in exchange for money, property, or services. And the company must meet an active business requirement for substantially all of the holding period, meaning it cannot be primarily a holding company, financial institution, or professional services firm.2Office of the Law Revision Counsel. 26 USC 1202 – Partial Exclusion for Gain From Certain Small Business Stock Term sheets for priced seed rounds often include a representation that the company will use reasonable efforts to maintain its qualification, because losing status retroactively destroys the tax benefit for every investor.
From Signed Term Sheet to Closing
Signing triggers an exclusivity period (sometimes called a no-shop), typically 30 to 60 days, during which the founders cannot solicit competing offers. That window gives the investor confidence to spend on diligence and legal work.
Diligence comes next. The investor’s lawyers verify the cap table, review intellectual property assignments to confirm the company owns what it claims, examine employment agreements, and look for undisclosed liabilities like unpaid taxes or pending lawsuits. Sloppy corporate housekeeping causes real delays here. If an early employee never signed an IP assignment, or option grants went out without proper board approval, those have to be cleaned up before closing. Have your current cap table, articles of incorporation, EIN, and board authorizations for every prior equity grant ready before drafting starts.3Internal Revenue Service.

Once diligence clears, counsel drafts the definitive agreements. For a priced round using NVCA forms, the core documents are the stock purchase agreement (the actual sale of shares, plus company representations and warranties), the investors’ rights agreement (information rights, registration rights, and related provisions), the voting agreement (board composition and drag-along), and the right of first refusal and co-sale agreement.4National Venture Capital Association. Model Legal Documents Starting from these templates keeps fees down and lets both sides focus energy on the terms that actually vary from deal to deal.
Legal costs vary with instrument and complexity. A SAFE round might cost a startup as little as $2,500 to $5,000. A priced round using simplified documents runs $15,000 to $30,000 at a boutique firm; a full NVCA-style round typically runs $25,000 to $45,000 on the company side, with larger rounds pushing toward $50,000 or more. The investor usually covers their own legal costs. The round closes when the funds hit the company’s bank account and the new shares are formally issued.
