The Series A Term Sheet, Line by Line: A Founder's Anatomy of Every Clause That Actually Matters
A Series A term sheet is a two-page, non-binding document that will shape your company for the next decade. Founders who understand every line negotiate better outcomes. Founders who do not lose more to the fine print than they ever lose on valuation.
The valuation of the company before the new money comes in. Post-money = pre-money + new investment. Ownership sold = investment / post-money.
Standard. Not usually where the fight is. Where the fight is: the option pool.
The lead investor almost always requires the option pool to be topped up before the round closes, meaning the pool dilution comes out of the founders' shares, not the new money.
If they ask for a 15% post-money pool on a company that currently has 5%, the incremental 10% dilutes only the pre-money holders. On a $10M investment at a $40M pre, that pool shuffle is worth roughly $4M in effective valuation — real money, silent.
Negotiate the pool size based on the actual hiring plan for the next 18 months, not a round-number default.
The amount the investor gets back before the common stock (founders, employees) sees a dollar. Three flavors:
1x non-participating. Standard, founder-friendly. Investor gets their money back OR their pro-rata share of proceeds, whichever is greater. 1x participating. "Double-dip." Investor gets their money back AND their pro-rata share on top. Bad for founders. Push back hard. 1x preference (2x, 3x). Shows up in down rounds and distressed deals. Very bad. If you see this, the deal is probably not worth taking.
If a later round prices below the current round, the earlier investor's conversion price gets adjusted. Two flavors:
Broad-based weighted average. Standard. Adjustment is proportional to the size of the down round. Fair to both sides.
Full ratchet. Investor's price resets to the lowest subsequent price. Catastrophic to founders and later employees in a down round. Refuse.
Broad-based weighted average. Non-negotiable if you can help it.
Usually a non-cash paragraph. 6–8% dividends "when declared by the board." Non-cumulative. Standard. Rarely paid, mostly optical.
If you see cumulative dividends, especially at 8% or higher, you have a hybrid debt-equity deal. Push back.
The single most important clause in the term sheet after economics.
2 founder seats 2 investor seats (lead + Series Seed lead if applicable) 1 independent director, mutually agreed
That is a 5-person board with 2 founder seats. Founders no longer have a majority.
3 + 2 board (3 founder seats + 2 investor) — sometimes possible at Series A, rare at Series B.
Independent director selection. You want mutual approval, not investor-only nomination. The "independent" director is often the swing vote and matters more than the two investor seats combined.
A list of company actions that require the preferred stockholders' consent. Standard list includes:
Threshold for debt and budget approval should not be so low that you cannot run the company day-to-day.
Executive hire consent is fine for CEO and CFO. Watch scope creep.
The clause should require majority preferred, not any single investor's veto.
Preferred votes on an as-converted basis alongside common. Standard.
If a majority of holders agree to sell the company, minority holders (including founders and employees) must sell too. Standard. What to negotiate:
Trigger threshold should be majority of both preferred and common, not preferred alone.
Minimum sale price (e.g., must exceed liquidation preferences by a defined multiple) — protects founders in a low-price acquihire.
If a founder wants to sell shares, the company (ROFR) and investors (co-sale) get first crack. Standard. Fair.
Rights around forcing the company to register shares for public sale. Legal boilerplate. Do not spend negotiation capital here.
Almost always, existing founder shares are re-vested at closing on a 4-year schedule with a 1-year cliff, with partial credit for time already served.
Credit for time served. If you have been at the company two years, you should vest 25–50% at closing, not restart from zero.
Double-trigger acceleration on change of control. If the company is sold AND you are terminated without cause within 12 months, remaining shares vest. Standard.
Single-trigger acceleration. Rare, hard to get, worth asking for if you have leverage.
Increasingly hard to enforce in the US, but investors will ask. A non-solicit on employees for 12 months is standard. Refuse anything longer than 24 months on non-compete.
Legal opinions, IP assignments from all founders and employees, no material adverse change. Standard. Do not fight this.
30–45 days is standard. During that window, you cannot solicit other term sheets. Refuse longer than 45 days.
The company reimburses the lead investor's legal fees, capped at a specific dollar amount ($30–75K is normal at Series A). Negotiate the cap down. Every dollar over the cap comes out of the round proceeds.
None of the above appears in a term sheet, but every one of them shapes the deal:
Who wrote the term sheet? If the lead's law firm drafted it, it will lean their way. Have your law firm redline.
Timing. A term sheet delivered on Friday for signing on Monday is a negotiation tactic. Slow it down. 72 hours minimum.
Multiple term sheets. The only thing that meaningfully improves terms. Even one credible alternative changes the tone of every conversation.
The partner, not the firm. You are marrying the specific partner. Reference them harder than they reference you.
A term sheet is a negotiation, not a contract. Once you sign, the definitive documents will be roughly 100 pages that follow the two-page term sheet. Anything not covered in the term sheet is up for grabs in the long form — where founders often lose the small print because they have run out of energy.
Negotiate hard on the term sheet. Negotiate harder on the definitives.
