A founder-friendly guide to term sheets: what they are, the key economic and control terms, whether they are binding, and how they fit into raising investment.
When an investor decides they want to back your company, the first concrete document you usually see is a term sheet. It is short — often just a few pages — but it shapes the entire deal that follows, from how much of your company you give away to who controls key decisions. Understanding what a term sheet says, and what it really means, is one of the most valuable skills a founder can develop. This guide explains what a term sheet is, the key terms it contains, whether it binds you, and how it fits into the wider fundraising process.
This article is general information, not legal or financial advice. For a specific deal, take professional advice before signing.
A term sheet is a short document that sets out the main terms on which an investor proposes to invest in a company, before the full legal agreements are drafted. Think of it as the blueprint for the deal: it captures the headline economics and control arrangements so that both sides agree on the shape of the transaction before spending time and money on detailed contracts.
Term sheets are most common in equity fundraising, where venture capital funds or angel investors put money in for shares. Similar documents go by names such as a letter of intent or heads of terms in other contexts, like acquisitions. Whatever it is called, the purpose is the same: to record the key points of agreement and provide a framework for what comes next.
The economic terms decide who puts in what, and who gets what. The headline items include:
Valuation grabs the headlines, but liquidation preference and the option pool often have a bigger effect on what founders actually keep.
The interaction between these terms matters enormously. A high valuation can be undermined by an aggressive liquidation preference or a large option pool taken from the pre-money figure. This is why founders are wise to model the outcomes on their cap table rather than focusing on the valuation number alone.
Beyond the money, a term sheet allocates power. Even a minority investor often negotiates rights that give them influence well beyond their percentage shareholding. Common control terms include:
| Term | What it does |
|---|---|
| Board composition | Who sits on the board and how many seats the investor gets |
| Investor consents | Decisions that need investor approval (reserved matters) |
| Voting rights | How votes are weighted on key issues |
| Information rights | The reports and accounts the investor is entitled to receive |
| Founder vesting | Whether founders earn their shares over time |
| Drag-along and tag-along | Rights affecting future sales of the company |
Reserved matters are worth particular attention. These are decisions — such as raising more money, selling the company, or changing the business plan — that cannot be taken without investor consent. They are reasonable in principle but can become restrictive if drawn too widely, so the detail matters.
A common misunderstanding is that a term sheet is just an informal note with no force. In reality, most of a term sheet is non-binding, but specific clauses usually are binding, and you need to know which is which.
The non-binding parts are the proposed deal terms themselves — valuation, share rights and so on — which only take legal effect when the long-form agreements are signed. The clauses that typically do bind both sides include:
Because the label term sheet does not by itself decide enforceability, you must read what each clause actually says. An exclusivity period, in particular, takes you off the market for other investors, so its length and terms are worth negotiating carefully.
A signed term sheet is a milestone, not the finish line. It signals that both sides are serious and sets the framework for the rest of the process, which generally runs like this:
The terms you accept also interact with any tax-advantaged investment scheme. Many UK angels invest through reliefs such as EIS and SEIS, and certain share rights or arrangements can affect eligibility, so it is worth flagging this early. Throughout, keep sight of the bigger picture: a term sheet is the foundation of raising investment, and the relationship it begins will usually outlast the negotiation by years.
A term sheet is the concise document that sets out the proposed terms of an investment before the full contracts are drawn up. It divides into economic terms — valuation, investment amount, share class, liquidation preference and the option pool — and control terms such as board seats, consents and voting rights. Most of it is non-binding, but clauses like exclusivity and confidentiality usually bind, so read carefully. Above all, look past the headline valuation to how the terms work together, model the impact on your ownership, and take experienced advice before you sign.
