What Is a Term Sheet? A Founder's Guide to the Document That Decides Everything

A term sheet is a one-to-three page document that captures the agreed economic and control terms of an investment. It is not the legally binding contract — that comes later, in the definitive documents. But the term sheet is the negotiation. By the time you sign one, 95% of the deal is locked in.

This article is a clause-by-clause guide to what you'll see in a typical 2026 seed or Series A term sheet, what's market, what's negotiable, and which clauses founders should push back on the hardest.

Two kinds of round, two kinds of paper

Before walking through clauses, the first fork in the road: are you raising on a SAFE / convertible note (most pre-seed and many seeds), or as a priced round (most Series A and increasingly some seeds)?

• SAFE / convertible note. A short, simple instrument that converts into equity at a future priced round. No board, no liquidation preference, fewer clauses. The term sheet (if any) is a few lines. We have a deeper guide: SAFE vs priced round.
• Priced round. A formal share issuance. New shares get issued, valuation is fixed, board structure is set. Term sheet runs longer.

Most of what follows is the priced-round version. SAFE rounds have analogous (but simpler) versions of the economic terms.

The economic terms

These are the clauses that decide who gets what and when.

Pre-money valuation

The price of the company before the new money goes in. If the pre-money is $20m and the round is $5m, the post-money is $25m, and the new investors collectively own $5m / $25m = 20%.

This is the headline number. It is not the most important number. Founders fixate on valuation; investors care about ownership and structure. A high valuation with bad structural terms is worse than a slightly lower valuation with clean ones.

Round size and ownership

The total amount being raised this round. Pair it with the pre-money valuation and you get the dilution: investors take ownership = round size / post-money. We unpack the maths in valuation and dilution explained.

Option pool

A pool of unallocated shares set aside for future hires. Almost always created (or topped up) at the time of the round, almost always coming out of the pre-money — meaning founders bear the dilution of the new pool, not investors.

A typical "shuffle" creates a 10–15% post-money pool. Investors prefer larger; founders prefer smaller. The negotiation here is real money. A 5% increase in option pool, on a $20m pre-money, is roughly a percentage point of founder equity.

Negotiate the size of the pool by reference to the actual hiring plan for the next 18 months, not by reference to "what's market". If you genuinely need a 12% pool, defend it; if you don't, defend a smaller one.

Liquidation preference

What investors get paid out at exit before founders or common shareholders. Standard in 2026 is 1x non-participating preferred: investors get back their money first (1x), then convert their preferred shares into common to share in the rest. They don't double-dip.

Watch out for:

• Participating preferred. Investors get their money back and their share of the rest. Founders get less in everything below the very largest exits. Push back hard.
• Multiple liquidation preferences (2x, 3x). Almost never appropriate at seed or Series A. Push back.
• Senior preferences in later rounds. Each subsequent round typically takes seniority over earlier rounds; structure this carefully so it doesn't crush early investors.

We have a piece on this: liquidation preference explained.

Anti-dilution

Protection for investors if you raise a future round at a lower valuation (a down round). The market standard is broad-based weighted average anti-dilution, which is fair and rarely punitive. Full-ratchet is far harsher and should be resisted.

Pro rata rights

The right (not obligation) for investors to participate in future rounds to maintain their ownership percentage. Standard for lead investors. Be careful about granting pro rata to too many small investors — your future cap table can get crowded.

We dig into the trade-offs in pro rata rights explained.

The control terms

These decide who holds power on key decisions.

Board composition

Who sits on the board after the round closes. A typical seed-led-by-fund round looks like:

• 1 investor seat (the lead)
• 1 founder seat (you, or you and your co-founder share two)
• Optionally, 1 independent

Or for two-founder seed companies, often:

• 1 investor seat
• 2 founder seats

For Series A:

• 1 lead investor seat
• 2 founder seats
• 1 or 2 independents (mutually agreed)

The board structure shapes a lot. A board with two investor seats and one founder seat is materially different from one with two founder seats and one investor seat. Push for founder-friendly board composition; it costs investors very little and protects you significantly.

Protective provisions

A list of decisions that require investor consent. Typical: changing the company's articles, taking on debt above a threshold, selling the company, issuing new shares senior to theirs, hiring/firing the CEO, paying dividends.

Some provisions are reasonable. Others (vetoing routine operational decisions) are not. Read them carefully. The longer the list, the more careful you should be.

Founder vesting

You re-vest your existing shares over four years, often with a one-year cliff, on closing. Yes, your own shares. Yes, this feels uncomfortable.

It's market. The reasoning: investors want to know that if a founder walks in 12 months, they don't keep all their equity. Negotiate for credit for time already spent — if you've been working on the company for two years, you should arrive at closing with two years of vesting credit, not zero.

Drag-along rights

Allow majority shareholders to compel minority shareholders to participate in a sale. Reasonable in moderation; pathological if structured to let a small set of investors force a sale against the founder's will.

Information rights

Investors get periodic financials, cap table updates, board observer rights. Mostly fine. Be wary of overly broad rights granted to non-board investors who could leak strategically sensitive data.

The "softer" terms that bite later

A few clauses to watch:

• Right of first refusal (ROFR). Investors get the right to buy founder shares before they're sold to anyone else. Standard. Confirm it doesn't apply to ordinary departures.
• Co-sale rights. Allow investors to sell their shares alongside founder shares in any secondary. Standard.
• No-shop / exclusivity. A common clause from when the term sheet is signed: you can't shop the deal to other investors for a period (typically 30–45 days). Reasonable, but cap it tightly.
• Expense reimbursement. Investors get their legal fees reimbursed by the company at close, capped at some amount ($35–75k typical for Series A). Negotiate the cap downward if it's high.
• Most favoured nation (MFN). A clause that says if you give a future investor better terms, this investor automatically gets the same. Mostly seen on SAFEs. Mostly fine but worth understanding.

What to negotiate, what to accept

A general principle: in early-stage rounds, you have most of your negotiating leverage on valuation, board composition, and option pool. You have less leverage on standard legal protections that almost every fund will require.

The negotiations that actually matter at seed/Series A:

• The valuation, by 10–25%.
• The size and composition of the option pool.
• The board structure (founder seats vs investor seats).
• The structure of the liquidation preference (1x non-participating vs anything else).
• The size of the no-shop window.

The negotiations that often don't matter as much as founders think:

• Information rights (you'd give them anyway).
• Most protective provisions (rarely invoked in healthy companies).
• ROFR and co-sale (largely standard).

A note on speed

Once a term sheet is signed, you typically have 30–45 days to sign definitive documents. Use them. Slow legal back-and-forth kills more deals than founders realise. Hire a startup-savvy lawyer. Read the documents yourself. Don't outsource your understanding — your lawyer's job is to flag issues, not to read for you.

And finally

A term sheet is the most consequential document you'll ever read in your company's early life. Don't let "this is a standard form" lull you. Read every clause. Ask your lawyer what each one means. Know which terms you'd negotiate and which you'd walk away from.

The investors you want will respect a founder who reads the term sheet carefully. They'll think twice about a founder who signs without reading.
