Is a term sheet legally binding?

Mostly not, but a few clauses usually are. Valuation, board seats and most economic terms are typically non-binding and can still shift before final legal documents, while exclusivity and confidentiality clauses are almost always enforceable from the moment of signature regardless of whether the deal ultimately closes.

What happens after a term sheet is signed?

The lawyers begin drafting the final legal documents based on what the term sheet says, and the company usually enters an exclusivity period during which it cannot solicit or accept other offers. Due diligence typically runs in parallel, and the terms rarely move much from what the term sheet already set out.

Can a founder negotiate a term sheet after receiving it?

Yes, and it is the normal moment to do so, before signature rather than after. Once signed, both sides and their lawyers anchor to what it says, and reopening a term afterward tends to read as bad faith even on points the document itself called non-binding.

What is the biggest mistake founders make with a term sheet?

Focusing entirely on the valuation number while skimming the control and process terms. Board composition, protective provisions and exclusivity length shape the company for years after signing, and exclusivity in particular is usually binding immediately, regardless of how the rest of the negotiation goes.

Term sheet: what it is and why the wording matters

A short summary of the terms an investor proposes — valuation, amount, control rights. Mostly non-binding, but it sets the shape of everything that follows, so what is conceded here is rarely won back later.

Why it matters

A term sheet is the first document in a fundraise that actually commits anyone to anything, and
that is exactly why it is dangerous to treat as a formality. Most of a fundraise up to this point
has been conversation — pitch decks, calls, a verbal "we're in." The term sheet is where an
investor writes down what they actually want in exchange for the money, and a founder who is
relieved to finally have an offer will often sign it faster than they read it.

The document itself is mostly non-binding. Valuation, board seats, liquidation preference, and
most of the economic terms can, in principle, still move before the final legal documents are
signed. In practice they rarely do. Once a term sheet is signed, both sides anchor to it, the
lawyers draft against it, and reopening a term that was "just a starting point" now reads as bad
faith. What gets written into a term sheet is, for almost every practical purpose, what the
company ends up with.

The parts that genuinely are binding matter even more, because founders read past them looking
for the valuation number. Exclusivity and confidentiality clauses are almost always enforceable
from the moment of signature, regardless of what happens afterward. Sign a term sheet with a
thirty-day exclusivity window and then get a better offer on day ten, and you are contractually
stuck talking to the first investor while the second one waits or walks away.

How it works

A term sheet is short by design — usually a handful of pages — but it carries three kinds of
terms that behave very differently from each other.

Economic terms. Valuation (pre-money and post-money), the amount being raised, the security
being issued, and any liquidation preference. These decide who gets what money when the company
eventually sells or winds down, and they are the terms a founder is most likely to focus on
exclusively.

Control terms. Board composition, protective provisions (the list of decisions that need
investor sign-off — a new raise, a sale, changing the business materially), information rights,
and pro-rata rights for future rounds. These decide who has a say in running the company, and
first-time founders routinely under-negotiate them because they are less visible on a spreadsheet
than the valuation line.

Process terms. Exclusivity, confidentiality, and the expenses clause (who pays legal costs if
the deal falls through). These are the ones most likely to be fully binding regardless of whether
the rest of the deal closes, and they are the ones founders read least carefully.

The document usually states plainly which sections are binding and which are not — read that
line first, not last. Where it is silent or ambiguous, get a lawyer to say so before signing,
because "mostly non-binding" is not the same as "safe to skim."

What to watch for

Exclusivity outlives your enthusiasm for the investor. A signed exclusivity clause holds even
if the relationship cools during due diligence, even if a better offer appears, and even if the
investor is slow. Negotiate its length before signing, not after you are inside it.

Control terms compound quietly. A board seat, a protective provision, and an information
right each look reasonable in isolation. Stacked across two or three rounds, they can leave a
founder needing investor sign-off for decisions that used to be theirs alone. Read every term
sheet against the ones that came before it, not just against this round's ask.

"Standard terms" is doing a lot of work in that sentence. Some of what gets called standard
is genuinely market practice; some of it is whatever the investor's lawyer templated last time and
nobody pushed back on. The only way to tell the difference is to ask a lawyer or an experienced
founder who has actually seen several term sheets, not to take the phrase at face value.

The valuation number is not the only number that matters. A high valuation attached to a
large liquidation preference or aggressive anti-dilution terms can leave a founder worse off in a
modest exit than a lower valuation with cleaner terms would have. Model the outcome, not just the
headline.

On GetDeal

Term Sheet is one of the eight fixed stages of the investment deal track on GetDeal, sitting
between Handshake and Due Diligence — so a founder always knows whether a term sheet is expected
next, is under discussion, or has already been agreed, instead of guessing from an email thread.
Both sides see the same stage at the same time, which matters most exactly where this term does
the most damage: a founder who cannot tell whether "we sent terms" means a term sheet is coming
or has already been sent loses the ability to negotiate its exclusivity window with a clear head.

The Playbook lays out what each of the eight stages unlocks and which agreement is signed at each
one, which is worth reading before a term sheet lands rather than after.
