A term sheet is a short document outlining the proposed terms of an investment — valuation, amount, investor rights — before the full legal agreements are drafted. It is explicitly non-binding on the actual investment decision: signing a term sheet does not obligate the investor to close, and it does not obligate the founder to accept if terms change during diligence. The exceptions are two clauses that usually are binding regardless — exclusivity (often called a "no-shop" clause) and confidentiality — which is why a founder should read a term sheet carefully even though most of it isn't a final commitment.
What is a term sheet in startup fundraising?
Think of it as a letter of intent that sets the shape of a deal before lawyers spend weeks drafting the actual investment documents. A term sheet is typically two to five pages and covers the economic terms (how much money, at what valuation, in exchange for what) and the governance terms (board seats, voting rights, information rights) that both sides have agreed to in principle. Once signed, it becomes the blueprint the actual legal documents — the stock purchase agreement, the investor rights agreement, any amended charter — are drafted against.
Because it's short and non-binding on the investment itself, founders sometimes underestimate how much a term sheet matters. In practice, nearly every substantive point gets negotiated at the term sheet stage — by the time lawyers are drafting the full documents, renegotiating a term that was already agreed in the term sheet is unusual and reads as bad faith to the other side.
What are the key clauses every founder should understand?
Beyond valuation and amount raised, the clauses that most affect a founder's outcome are: liquidation preference (what investors get paid first, and how much, before common shareholders see anything at an exit), board composition (how many seats investors get and what that means for founder control), protective provisions (which decisions require investor consent even though the founder runs the company day-to-day), and the option pool (whether new equity set aside for future hires comes out of the pre-money valuation, which dilutes existing shareholders including the founder, not the new investor).
Two clauses that read as boilerplate but aren't: the no-shop/exclusivity period (how long the founder is locked out of talking to other investors while this deal is being finalized) and the expenses clause (whether the founder's company pays the investor's legal fees regardless of whether the deal closes).
What is a liquidation preference and why does it matter?
A liquidation preference determines who gets paid first, and how much, when the company is sold or liquidated — before any remaining proceeds are split among common shareholders (which usually includes founders and employees). A standard "1x non-participating" preference means preferred investors get their investment back first, then the rest is split as if everyone converted to common shares — investors take whichever is larger, their money back or their pro-rata share, not both.
The terms that matter most to a founder are the multiple (1x is standard; anything above that means investors get more than their money back before anyone else sees anything) and whether it's participating (investors get their preference back and then also participate in the remaining split, effectively double-dipping) or non-participating (investors choose one or the other, not both). A high multiple or a participating preference materially changes a founder's actual payout in a modest exit, even if the headline valuation looked attractive.
What is pro rata rights and should you give them?
Pro rata rights give an existing investor the right, but not the obligation, to invest in future rounds to maintain their current ownership percentage — if an investor owns 10% after this round, pro rata rights let them buy enough of the next round to still own roughly 10% afterward, rather than being diluted down.
For most founders, granting pro rata rights to early investors is a reasonable, standard practice — it rewards investors who took risk early and rarely costs the founder anything material, since the investor is buying in at the new round's price, not a discount. Where founders should pay attention is in oversubscribed rounds — if a hot round has more investor demand than room, pro rata commitments from earlier rounds can crowd out the amount available for new investors the founder actually wants to add. This is a real tradeoff, not a formality, and worth thinking through before granting broad pro rata rights early.
How long does it take to go from term sheet to close?
For a straightforward seed or Series A, four to eight weeks is a realistic range from a signed term sheet to a closed round, assuming diligence doesn't surface anything unexpected. That period covers legal document drafting, due diligence on the company's financials and cap table, and negotiation of the final agreement details that the term sheet only sketched. Complex rounds — multiple investors, unusual instrument structures, regulatory considerations — can take considerably longer.
The exclusivity period in the term sheet usually covers this whole window, which is part of why founders should negotiate that period's length carefully rather than accepting whatever's proposed — a 60-day no-shop clause on a deal that then stalls for unrelated reasons leaves the founder with no other option to pursue in the meantime.
Recording what was actually agreed
The gap between what a term sheet says and what the final legal documents say is a common source of later disputes — a founder remembers the term sheet's numbers, an investor's counsel drafts language that technically differs, and reconciling the two after the fact is expensive. On Lengdon, the negotiated version of a term sheet — including any counter-offers exchanged before agreement — is part of the deal room's record at the Terms stage, so what was actually proposed and accepted is retained exactly as agreed, not reconstructed from memory once the final documents are being drafted.
FAQ
Is a term sheet legally binding?
Mostly no — the core investment terms (valuation, amount, structure) are typically non-binding, meaning either side can still walk away during diligence. The exceptions are usually the confidentiality and exclusivity (no-shop) clauses, which are binding even though the rest of the document isn't.
What should a founder negotiate on a term sheet?
Valuation and amount get the most attention, but liquidation preference multiple and participation, board composition, and the length of the exclusivity period usually matter more to the actual outcome. A founder who negotiates only the headline valuation while accepting whatever governance terms are proposed often gives up more than they realize.
How long is a term sheet valid?
There's no universal standard — it depends on the exclusivity period specified in the document itself, commonly 30 to 90 days. After that period expires without a closed deal, the founder is generally free to pursue other investors again, though the specific expiration terms should always be read directly rather than assumed.
