A term sheet is a short, mostly non-binding summary of the deal an investor is proposing — and the valuation headline at the top is usually the least important thing on it. The clauses that decide what you actually walk away with are liquidation preference, anti-dilution protection, protective provisions, board composition, and founder vesting. A high valuation with a stacked preference and broad veto rights can leave founders worse off than a lower valuation on clean terms, which is why experienced founders read a term sheet from the bottom up.

What a Term Sheet Is and Is Not

It is a statement of principles, typically two to five pages, that the definitive documents will later implement in full legal detail. Most of it is expressly non-binding — but two provisions usually are binding: confidentiality and exclusivity. That second one has teeth, as discussed below.

Signing a term sheet is nonetheless the practical point of no return in most rounds. Terms that go in unchallenged at this stage almost never get renegotiated during documentation, because the leverage has already shifted. If a clause bothers you, the moment to say so is before you sign.

The Clauses That Matter Most

Liquidation Preference

This determines who gets paid first, and how much, when the company is sold. A 1x non-participating preference — the standard, founder-reasonable form — means the investor takes back their investment or converts to common stock and shares pro rata, whichever is better for them, but not both. Watch for two variations that change the outcome materially: a multiple greater than 1x, and "participating" preferred, where the investor takes their money back and then also shares in the remainder. Both are most damaging in a modest, realistic exit, exactly the scenario nobody models in the pitch.

Preferences also stack across rounds. Several rounds of participating preferred can consume most of the proceeds of a mid-sized acquisition before common shareholders see anything.

Anti-Dilution Protection

This protects the investor if you later raise at a lower valuation. "Broad-based weighted average" is the normal, negotiable form and adjusts their price partially. "Full ratchet" re-prices their entire holding as if they had invested at the new lower price, which transfers a great deal of ownership away from founders and employees in a single move. Full ratchet is worth pushing back on hard. Understanding the mechanics alongside our guide to equity dilution makes the effect concrete.

Protective Provisions (Veto Rights)

A list of actions requiring investor consent. Some are entirely normal: selling the company, issuing a new senior class of stock, taking on large debt, changing the size of the board. Where it becomes a problem is when the list extends into ordinary operations — hiring above a low salary threshold, any capital expenditure over a small figure, approving the annual budget. For a hardware company those thresholds are easy to trip, since tooling and test equipment are legitimately expensive. Read the list against a realistic year of operations and ask whether you can still run the business.

Board Composition and Control

Count seats and understand who appoints them. A common early structure is two founder seats, one investor seat, and one mutually agreed independent director. What matters is not just the arithmetic today but what happens after the next round, when a second investor also wants a seat. Board control and share ownership are separate things, and losing the first while keeping the second is a real and unpleasant possibility.

Founder Vesting

Yes, your own shares. Investors routinely require founders to re-vest, usually over four years with a one-year cliff, so that a departing founder does not keep a large stake for nothing. This is reasonable in principle. What to negotiate is credit for time already served, acceleration on a change of control, and what "termination" means — you do not want a structure where being removed without cause forfeits your equity. If you have co-founders, these terms interact with whatever you agreed among yourselves; see how to split equity between co-founders and our guide to a founders agreement.

Pro Rata, Information Rights, and Option Pool

Pro rata rights let the investor maintain their percentage in future rounds — normal, though very broad versions can crowd out a new lead later. Information rights obligate you to regular reporting, which is reasonable but should be defined so it does not become a monthly research project. And watch where the new employee option pool sits: if it is created before the investment, it dilutes existing shareholders only, which quietly lowers your effective valuation. This is the single most common place the headline number is undermined — the mechanics are covered in pre-money vs post-money valuation.

Exclusivity, Conditions, and Timing

Exclusivity, or "no-shop," stops you from talking to other investors for a defined period. Thirty to forty-five days is normal; ninety days with an unmotivated investor can kill a company that is running out of runway. Negotiate the length, and make sure it terminates automatically if the investor walks away.

Closing conditions deserve equal attention: satisfactory due diligence, delivery of specific documents, sometimes a technical or IP review. For a hardware or IP-heavy company, expect questions about who owns your engineering work and whether your filings are in order — our guides to investor due diligence and who owns the IP in product development cover what gets examined and where the paperwork gaps usually are.

Signals of an Investor Who Will Be Difficult

  • Aggressive terms paired with a flattering valuation. The valuation is the sweetener; the terms are the deal.
  • Refusal to explain a clause in plain English. Anyone unwilling to say what a provision does in a bad scenario is telling you something.
  • Long exclusivity plus vague conditions. That combination gives them a free option on your company.
  • Extremely fast-expiring offers. Legitimate investors give you time to get counsel.
  • Operational veto rights at low thresholds. Often a sign of an investor who intends to manage rather than back you.

How to Approach It Sensibly

Get a startup attorney involved before you sign anything, not after. Model the outcome at several exit values — a modest sale, a decent one, a great one — and see what each clause does to your proceeds in each case; the results are usually surprising in the lower scenarios. Prioritize: you will not win every point, so decide in advance which two or three matter most, and trade the rest. Compare against the alternatives you have, including simpler early instruments such as a SAFE and non-dilutive routes described in grants vs investors. And remember that terms are negotiated relative to your leverage — a working prototype, a signed pilot customer, or a second interested investor changes what you can ask for far more than any argument you make at the table.

Projects House builds the engineering side of that leverage: a working prototype, credible cost figures, and a clean technical package that survives diligence. If you want your product far enough along that you negotiate from strength, tell us what you are building through our contact form.
