A term sheet is the document that lays out the proposed economic and governance terms of a startup investment before anyone pays legal fees to draft the real contracts. Most of what it contains is a negotiated statement of intent that will feed into definitive agreements later. A small number of clauses, however, carry legal weight the instant both sides sign. Confusing the two categories is how founders lose leverage, equity, or the deal itself.
What Actually Binds You at Signing
Courts have been consistent on this point. When a term sheet conditions its terms on future definitive documentation, the economic provisions are not enforceable on their own. In Amcan Holdings v. Canadian Imperial Bank of Commerce, a New York court held that even a highly detailed term sheet creates no binding obligation when it states that final terms depend on a future agreement that hasn’t been executed. Valuation, share price, and dividend terms can shift up until you sign the stock purchase agreement.
Three categories of clauses typically do bind immediately:
- Confidentiality. Both sides agree not to disclose the deal terms or the other party’s proprietary information. Public companies may carve out mandatory SEC filings, but silence is the default.
- Exclusivity, often called the no-shop. The company agrees not to solicit or entertain competing offers for a set window, usually 30 to 90 days, giving the lead investor time to run diligence without being outbid.
- Governing law. The clause designating which state’s law controls disputes over the term sheet. In venture deals, this is almost always Delaware or the investor’s home state.
Because these binding clauses sit alongside non-binding economic terms, the document should contain an express statement identifying which sections are enforceable. If yours doesn’t, flag it with counsel before signing.
Valuation and the Math That Follows It
The pre-money valuation is the agreed value of the company before the new money comes in. Divide that figure by the fully diluted share count and you get the per-share price the investor will pay. Fully diluted means every outstanding share, every vested and unvested option, and every share reserved in the employee option pool. Leaving anything out inflates the price per share and creates disputes later.
The arithmetic is straightforward. A $10,000,000 pre-money valuation and a $2,000,000 investment produces a $12,000,000 post-money valuation, with the new investor owning roughly 16.7 percent. These figures populate the capitalization table that tracks each shareholder’s ownership before and after the round.
The Option Pool Comes Out of Your Shares
Investors almost always require the company to set aside an employee option pool before closing, and the dilution from that pool falls on the founders, not the incoming investors. Data from startup equity platforms shows that over half of venture-backed companies reserve between 10 and 20 percent of their fully diluted capitalization for the pool, with 15 percent as a common midpoint. If an external CEO hire is on the horizon, expect investors to push that number 6 to 8 percentage points higher. This is one of the most consequential negotiations in the whole document, because a larger pool dilutes founders more than the headline valuation suggests.
Liquidation Preferences: Who Gets Paid First
Liquidation preferences decide who gets paid first, and how much, when the company is sold, merged, or wound down. The founder-friendly standard is a 1x non-participating preference: the investor takes back whichever is greater between their original investment or their pro-rata share of the sale proceeds, but not both. Once the sale price is high enough, the investor converts to common and splits the proceeds proportionally.
A participating preference is far more aggressive. The investor gets their investment back first, then also takes a percentage of what remains. This double dip can sharply cut what founders and employees receive in a moderate exit. Some term sheets cap participation at a multiple such as 2x or 3x the original investment. Uncapped participation is a red flag worth pushing back on hard.
Anti-Dilution: Weighted Average vs. Full Ratchet
Anti-dilution protects investors if the company later raises at a lower valuation. Two mechanisms dominate.
- Broad-based weighted average. The conversion price of the existing preferred stock is adjusted downward using a formula that accounts for both the lower price and the number of new shares issued. A small down round triggers a small adjustment. This is the standard default in venture deals.
- Full ratchet. The conversion price drops all the way to the new lower price, regardless of how many shares are issued. Even a tiny round at a discount triggers the maximum adjustment, dilutes founders heavily, and makes future fundraising harder because incoming investors see existing holders benefiting disproportionately from any price decline.
In a downturn, the gap between these two is severe. A small bridge round at a discount causes a modest adjustment under weighted average and can shift several percentage points of ownership under full ratchet.
Dividends and Conversion
Term sheets specify whether preferred shareholders receive dividends and whether those dividends are cumulative or non-cumulative. Non-cumulative dividends are paid only when the board declares them, and skipped years are gone. Cumulative dividends accrue whether the board declares them or not, and the accumulated amount must be paid before common shareholders see anything in a liquidation. Model out what several years of cumulative dividends would look like at exit before you accept the clause.
Preferred stock usually carries two conversion rights. Optional conversion lets the investor convert to common at any time, typically one-to-one subject to anti-dilution adjustments. Mandatory conversion forces all preferred to convert on a triggering event, typically a qualified IPO meeting a minimum size or valuation threshold, which clears the liquidation preference stack before the company goes public.
Governance: Board, Vetoes, and Forced Sales
The governance section allocates post-closing decision-making. Board composition is the headline item: how many seats go to founder designees, how many to the investor, and whether there are independents. A typical Series A might show two founder seats, one investor seat, and one independent, with the balance tilting toward investors in later rounds. Preferred shareholders generally vote with common on an as-converted basis.
Protective Provisions
Protective provisions give preferred shareholders veto power over specific corporate actions regardless of how the board is composed. Standard items on the list include selling or merging the company, amending the certificate of incorporation, issuing new debt above a specified threshold, and changing the dividend rights of existing shares. These go beyond what Delaware corporate law already requires. Delaware already demands a class vote for charter amendments that adversely affect a class of stock; protective provisions in the term sheet typically require investor consent for actions Delaware alone would not block.
Drag-Along and Tag-Along
Drag-along rights let majority shareholders force minority holders to join a sale on the same terms, preventing a single holdout from blocking an acquisition everyone else supports. The term sheet specifies the approval threshold that triggers the drag, often a majority or supermajority of preferred and common voting together. Tag-along rights work the other way: if a controlling shareholder sells, minority holders can sell a proportional amount at the same price, protecting them from being stranded under new ownership.
Founder Vesting and the 83(b) Clock
Investors almost always require founders to vest their equity over time, even if the founders have held their shares for years. The standard is four years of vesting with a one-year cliff: leave before the first anniversary and all unvested shares are forfeited; after the cliff, shares typically vest monthly.
Vesting creates a tax decision with a hard 30-day deadline: the 83(b) election. Filing with the IRS lets you pay tax on the stock’s value at the time of grant rather than at vesting. If the stock is worth very little at grant and significantly more when it vests years later, the election locks in the lower taxable amount and can save substantial money. Miss the 30-day window and the election is gone permanently, with no extension and no appeal. The IRS requires the election on Form 15620.1Internal Revenue Service. Form 15620, Section 83(b) Election The statute makes clear the election cannot be revoked without IRS consent, so you are committed either way.2Office of the Law Revision Counsel. 26 USC 83 – Property Transferred in Connection With Performance of Services
Pro-Rata, Information Rights, and Pay-to-Play
Pro-rata rights let existing investors invest enough in future rounds to maintain their ownership percentage. An investor holding 5 percent after the Series A can buy up to 5 percent of new shares in the Series B. Founders should pay attention to who receives these rights. Granting them broadly to every small check writer creates logistical headaches and reduces the allocation available for new lead investors later.
Investors above a specified ownership threshold, usually labeled Major Investors, negotiate for ongoing financial access. Standard information rights include audited annual financials within 90 to 180 days of year-end, unaudited quarterly statements within 45 days of quarter-end, an updated cap table, and the board-approved annual budget. Some push for monthly income statements. Competitors can usually be excluded even if their venture arm would otherwise qualify.
Pay-to-play clauses add teeth to future fundraising. Existing preferred holders who don’t invest their pro-rata share in a future round have some or all of their preferred stock converted to common, which strips the liquidation preference, protective provision votes, and board rights. The clause discourages investors from free-riding on preferred protections while declining to support the company when it needs more capital. Founders generally favor these provisions.
What Happens Between Signing and Closing
Signing triggers the binding provisions and opens a due diligence window that typically runs four to eight weeks for early-stage companies. Investor counsel and finance teams verify what the company represented during negotiations. Expect requests for historical financials, a current cap table with full option grant detail, material contracts, intellectual property documentation, employment agreements for key personnel, a client list with references, any pending or threatened litigation, and outstanding debt. Companies that gather these before signing move through diligence faster and avoid the deal fatigue that kills transactions.
If nothing deal-breaking surfaces, the parties draft definitive documents. The core package is the Stock Purchase Agreement, which replaces the term sheet as the binding contract; the Investors’ Rights Agreement, which covers information rights, registration rights, and pro-rata rights; and the Right of First Refusal and Co-Sale Agreement, which covers transfer restrictions, tag-along, and drag-along.3National Venture Capital Association.

Regulatory Filings After the Money Lands
Most venture financings rely on a federal exemption from SEC registration under Regulation D. Under Rule 506, a company can raise an unlimited amount from accredited investors, with reasonable verification of accredited status required if the offering involves general solicitation.4eCFR. 17 CFR 230.506 – Exemption for Limited Offers and Sales
After the first sale of securities, the company must file a Form D notice with the SEC within 15 calendar days. The first sale date is the date the first investor becomes irrevocably committed, not the date funds transfer. There’s no filing fee, but missing the deadline can jeopardize the exemption and complicate future rounds.5U.S. Securities and Exchange Commission. Filing a Form D Notice State-level blue sky filings are also required in most jurisdictions where securities are sold or investors reside, with varying deadlines and fees. Securities counsel should handle both federal and state filings as part of closing.
