Term sheets: an overview

A term sheet is a short document (often 5–15 pages) that outlines the deal a venture investor proposes. It is mostly non-binding, but it is the map everyone will follow when lawyers draft the definitive documents. Negotiate hard here. Recutting economics after the sheet is signed is painful and reputation-damaging; "we'll fix it in the docs" is how founders lose.

Think of it as a compressed specification. The long-form documents are the implementation. If the spec is wrong, the implementation will faithfully encode the wrong deal at 10× the legal cost. Slow down for economics and control; move fast on boilerplate once those are right.

Concept

The NVCA (National Venture Capital Association) publishes model legal documents — a term sheet plus the long-form agreements that implement it. Most US counsel start from these forms and redline. You need to know which blanks matter and what "market" looks like for your stage.

Step	Concept	What it answers
1	Economics vs control	Who gets the money, and who decides?
2	Binding terms	What actually locks you in before closing?
3	Market terms	What does a clean seed or Series A look like?
4	Negotiating the sheet	What do you fight first, and how do you read a sheet in thirty minutes?

From sheet to close

After the sheet is signed, the real work starts: diligence (records, IP assignments, cap table, SAFEs, contracts), long-form drafts that should track the sheet, board and stockholder approvals, then signature packets and wiring. Expect 4–8 weeks from a signed Series A sheet to close if the cap table is clean; longer with many SAFEs, international investors, or disputed IP. Company usually pays its own counsel plus a capped fee for investor counsel.

If a new economic term appears in long-form, escalate immediately. Assign one founder as closing owner with a shared checklist. A founder who disappears into product for three weeks during exclusivity burns the no-shop clock.

Seed sheets are often shorter. Do not assume "short" means "safe" — a two-page seed sheet can still hide participating preferred. The same economic-vs-control lens applies.

Tip

Keep a single "open points" list: commercial issues (pool size, board naming, fee caps) vs documentary issues (rep carve-outs, disclosure schedule). Do not mix them in a 40-email thread.

Engineers rarely negotiate sheets, but they live inside the outcomes: option pools, preference overhang, board-driven pivots. If you join a startup, ask whether the last round was clean 1× non-participating and whether the pool can support hiring.

Common mistakes

Signing the first sheet to "create momentum" with no second conversation in flight. Exclusivity then freezes price discovery.
Letting counsel negotiate valuation. Lawyers flag non-market terms; founders decide commercial tradeoffs.
Ignoring existing SAFE side letters. Pro-rata promises to angels can collide with the lead's allocation.
Celebrating on Twitter before closing. Markets move; diligence finds issues.

Key takeaways

Term sheets split into economics and control; negotiate both, not just price.
Most terms are non-binding; no-shop and confidentiality usually bind.
Never sign without a pro forma cap table and a quick waterfall at a few exit values.
Use experienced venture counsel; commercial calls stay with the founders.
