Understanding term sheets for UK startup fundraising: a practical guide for founders

Raising investment is a major milestone for any startup. Before the long-form legal documents arrive, you will probably see a term sheet. It sets out the main commercial points of the deal in a few pages, and getting comfortable with its language early on saves you time, money and stress later.

This guide walks through the most common terms you will encounter. It is not legal advice. You should always get a solicitor who knows startup funding to review your specific term sheet before you sign anything.

What a term sheet is, and what it is not

A term sheet is a summary of the key investment terms. Think of it as a heads of terms for your funding round. It is typically non-binding on the main commercial points, except for a few sections like confidentiality, exclusivity and costs. Some angel investors or VC funds will issue their own template; others will negotiate with you from a starting document.

The point of the term sheet is to agree the big picture before lawyers draft the full investment agreement (usually a subscription and shareholders’ agreement). Getting the term sheet right avoids wasting time and legal fees on a deal that founders and investors see differently.

Valuation and the economics

The first section you will look at covers the numbers.

Pre-money valuation is what the company is worth before the new money comes in. The investment amount is how much the investor is putting in. Together they give you the post-money valuation and the percentage of the company the investor will own. For example, a £1m pre-money valuation plus a £250k investment means the investor gets 20% of the enlarged share capital.

Type of security tells you what the investor actually buys. In the UK, this is often ordinary shares, but it may be a convertible loan note or an advanced subscription agreement (ASA). A convertible loan note is a loan that converts into equity later, typically at a discount or with a valuation cap. An ASA is a simpler version of a convertible note that is very common in seed rounds. If you are using a SAFE (Simple Agreement for Future Equity), understand that it is a US concept; a UK-adapted version may be used but needs careful advice.

Liquidation preference matters when the company is sold. A 1x non-participating preference means the investor gets their money back first, then shares any remaining proceeds with other shareholders. A participating preference allows the investor to get their money back and then also share in the rest. These terms can dramatically affect what founders take home in an exit. Most early-stage UK rounds settle on a 1x non-participating preference, but always check.

Anti-dilution protection adjusts the investor’s shareholding if you later raise money at a lower valuation (a down round). Full-ratchet anti-dilution is aggressive and can seriously dilute founders. Weighted-average provisions are more moderate. Many early-stage rounds omit anti-dilution altogether or use a lighter form.

Governance and control

Investors typically want certain rights to protect their minority stake.

Board seats give the investor a director or observer position. Consider how this affects board dynamics and decision-making. A single investor director on a three-person board is workable for many startups.

Protective provisions (also called veto rights or reserved matters) are a list of things the company cannot do without investor consent. They often cover issuing new shares, changing the articles of association, taking on debt above a threshold, selling the business or changing the board. You want these to be sensible, not so broad that they paralyse day-to-day operations.

Information rights require you to provide regular updates, such as monthly management accounts, quarterly reports and annual audited accounts. Most founders are already providing some of this, so it is rarely contentious if the scope is reasonable.

Founder and employee shares

Investors need to know the team is locked in.

Vesting means your shares (or a portion of them) are earned over time. A typical schedule is four years with a one-year cliff. So if you leave after 12 months, you keep 25% of your shares; after that, you vest monthly. It is now common for new investment to require founders to restart vesting on a significant chunk of their holding, especially if they only recently started the company. This can feel uncomfortable but is standard practice.

Good leaver / bad leaver provisions determine what happens to a founder’s shares if they leave. A good leaver (e.g., illness, agreed departure) might be allowed to keep all or most of their vested shares. A bad leaver (e.g., gross misconduct) may lose their vested shares or have them bought back at a low price. Get these definitions clear and fair.

Drag-along rights allow a majority of shareholders to force remaining shareholders to sell their shares in a company sale. This stops a small shareholder blocking an exit. Tag-along rights protect minority shareholders by letting them join the sale on the same terms if a majority sells. Both are market standard.

The parts that are actually binding

A few sections in a term sheet are typically legally binding on both sides. These usually include confidentiality, exclusivity (no shop) and who pays legal costs. Do not treat them as casual statements. If an investor asks for a long exclusivity period with no clear timeline to finalise legal docs, that can freeze you out of other conversations.

Practical steps when you receive a term sheet

1. Read it carefully, even before your lawyer does. Highlight anything you do not understand.
2. Get a startup solicitor to review it. Do not rely on a friend who did a round once.
3. Compare the terms against what you see in markets like SeedLegals or industry reports. This helps you understand what is normal for your stage.
4. Negotiate the points that will hurt you later, not the ones that sound nice. Valuation grabs attention, but liquidation preferences, anti-dilution and board composition often matter more.
5. Keep the conversation collaborative. A term sheet is the start of a long relationship.

A clear, well-negotiated term sheet sets up your round properly and helps you move to the full legal paperwork with fewer surprises. Always take the time to understand it and get proper advice.
