What Are Investors? Types, Rights And Key Legal Documents

If you’re growing a business, chances are you’ll hit a point where you need more than grit and good cashflow to reach the next stage.

That’s where funding comes in - and one of the most common questions founders ask is: what are investors, and what do they actually want in return?

In simple terms, investors are people or organisations that put money (or other value) into your business with the expectation of a return. That return might come from dividends, interest, or an increase in the value of their shares when you sell the business or raise again.

But for UK small businesses, the more important question is usually this: what rights will your investors get, and what legal documents should you have in place so you stay protected from day one?

Let’s break it down in plain English.

What Are Investors (And What Do They Typically Want)?

Investors are not just “people who give you money”. They’re entering into a legal and commercial relationship with your business.

Broadly, investors usually want one or more of the following:

• Ownership (usually via shares) so they benefit if your business grows in value
• Income (for example, interest on a loan, or dividends if/when you start paying them)
• Some level of control (such as voting rights, approval rights, or board representation)
• Protection (so their investment isn’t diluted or devalued unfairly)
• A clear exit path (how they get their money back - and ideally profit - later)

From your side as a founder, you’re usually looking for:

• Capital to hire staff, buy equipment, build product, or scale marketing
• Strategic support (networks, introductions, operational guidance)
• Credibility (having reputable investors can help future fundraising)

The key is making sure both sides understand what’s being agreed - and documenting it properly. Even a “friendly” investment can turn messy if expectations aren’t set out in writing.

What Types Of Investors Might Fund A UK Small Business?

There isn’t a single definition of “investor” in day-to-day business. In practice, you’ll come across different investor types depending on your stage, sector, and funding needs.

1. Friends And Family Investors

This is often the earliest kind of investment - a parent, sibling, friend, or family connection backing your idea.

It can feel informal, but that’s exactly why it can be risky. If the business struggles or pivots, personal relationships can take a hit.

If you’re taking friends and family money, it’s usually worth treating it like a professional round and documenting:

• Whether it’s a loan or shares
• What happens if the business fails
• Whether they get any say in decision-making

2. Angel Investors

Angels are individuals who invest their own money, usually into early-stage businesses. They may also bring valuable experience and connections.

Angel investment often comes with expectations around reporting, future fundraising, and protections like anti-dilution or approval rights for key decisions.

3. Venture Capital (VC) Investors

VCs are typically investment funds that invest other people’s money. They usually invest in businesses with high growth potential (often tech-enabled or scalable models), and they tend to be more structured about:

• Due diligence
• Investor rights and controls
• Growth targets and follow-on rounds

VC rounds tend to involve heavier documentation and negotiation - and it’s usually where having your legal foundations tidy really pays off.

4. Corporate Or Strategic Investors

Sometimes another business invests in you (for example, a supplier, distributor, or larger player in your industry).

This can be great for growth, but it can also create conflicts (for example, exclusivity pressure, restrictions on who you can work with, or IP concerns). Be extra careful about what’s being traded beyond cash.

5. Lenders And Debt Investors

Not all “investors” take shares. Some provide money as a loan, expecting repayment plus interest.

Debt funding can be useful when you don’t want dilution, but it does create repayment pressure and often comes with default consequences if the business can’t pay.

Even where funding is debt-based, the documents still matter - you want repayment terms, interest, security (if any), and enforcement clearly set out.

Equity Vs Debt: How Investors Can Put Money Into Your Business

When small business owners ask what are investors, they’re often really asking: “Are they buying part of my business, or lending money to it?”

Most investment structures fall into three buckets.

Equity Investment (Shares)

Equity investors buy shares in your company. In return, they become shareholders and get rights under:

• company law (mainly the Companies Act 2006)
• your company’s constitutional documents
• the specific agreements signed for the investment

Equity is common when:

• the business is high growth, but not yet profitable
• you want “patient capital” with no monthly repayments
• the investor is backing long-term value

Equity does mean dilution - you’re giving away a percentage of ownership (and potentially control), so it’s essential to get the terms right.

Debt Investment (Loans)

Debt investors lend money to the company, usually with interest. This can be documented in a loan agreement and may or may not be secured against business assets.

Debt is common when:

• you have predictable cashflow to service repayments
• you want to avoid dilution
• the investor prefers lower risk and fixed returns

Convertible Or Hybrid Investment

Some investors use “in-between” instruments. For example, money may start as a loan but convert into shares later (often at a discount) when you do a future funding round.

This can be helpful if you’re raising quickly and don’t want to argue about valuation yet - but it needs careful drafting to avoid surprises later.

In startup funding, that often means documents like a Convertible Note or an Advanced Subscription Agreement, depending on how the round is structured. If you’re considering SEIS/EIS, it’s also worth getting tax advice early, as the structure and drafting can affect eligibility and tax treatment.

What Rights Do Investors Usually Ask For In The UK?

Investor rights are not one-size-fits-all. A small friends-and-family cheque shouldn’t necessarily come with the same control rights as a major institutional round.

That said, there are some common rights that investors often negotiate for in the UK.

Share Rights: Voting, Dividends And Class Rights

If you issue shares, your investors’ rights may depend on the class of shares they receive (ordinary shares, preference shares, etc.). Rights can include:

• Voting rights (ability to vote on shareholder resolutions)
• Dividend rights (rights to a share of profits if dividends are declared)
• Priority on exit (preference shareholders may be repaid before ordinary shareholders)

These rights should align with your Articles of Association (your company constitution) and any investment documentation.

Information And Reporting Rights

Investors may ask for regular updates such as management accounts, budgets, KPIs, or annual financial statements.

For small businesses, the key is making sure these reporting requirements are realistic - you don’t want to promise monthly reporting if you don’t have the systems (or time) to do it.

Pre-Emption Rights (Protection Against Dilution)

Pre-emption rights typically give existing shareholders the right to buy new shares before you offer them to outsiders.

This helps protect investors from dilution, and it can also help you maintain a stable shareholder base - but it may make future fundraising slower if not managed carefully.

Reserved Matters / Investor Consent Rights

Reserved matters are decisions the company can’t make unless the investor (or a group of investors) approves. These might include:

• issuing new shares
• taking on large debt
• changing the company’s business model significantly
• selling major assets
• appointing or removing directors

This is a common area where founders can accidentally give away more control than they intended - especially if they’re negotiating quickly under pressure.

Exit Rights: Drag-Along, Tag-Along And Transfer Restrictions

Many investors care most about how they eventually get liquidity (i.e. turning their shares back into cash).

Investor-friendly terms can include:

• Tag-along rights (if founders sell, investors can “tag” their shares into the sale)
• Drag-along rights (if a majority agrees to sell, minority shareholders may be “dragged” into the sale)
• Transfer restrictions (stopping shareholders from selling to anyone without approvals)

These are usually set out in a Shareholders Agreement.

Key Legal Documents When Bringing Investors Into Your Business

Bringing investors in is one of those milestones where DIY documents can create long-term problems. The right documents protect you, your co-founders, and your investors by making the deal clear and enforceable.

Here are the key legal documents we commonly see in UK small business investment rounds.

Term Sheet

A term sheet sets out the headline commercial terms before the full legal documents are drafted. It’s usually where you agree:

• how much is being invested
• valuation (or the mechanism if it’s a convertible structure)
• what rights the investor will receive
• key conditions before completion

Even when a term sheet is stated to be “non-binding”, parts of it (like confidentiality or exclusivity) can be binding - so it’s worth treating it seriously. Many businesses choose to formalise this stage with a proper Term Sheet.

Share Subscription Agreement

If the investor is buying new shares from the company (not buying existing shares from a founder), you’ll typically need a subscription agreement.

This document usually covers:

• the number and class of shares being issued
• the purchase price and payment mechanics
• conditions precedent (what must happen before shares are issued)
• warranties (promises about the company’s status, IP, compliance, etc.)

This is often handled with a Share Subscription Agreement.

Shareholders Agreement

Your shareholders agreement is the “rulebook” between shareholders and the company. It’s where you usually document:

• how decisions are made and who controls what
• reserved matters requiring investor consent
• pre-emption rights and transfer restrictions
• deadlock procedures (what happens if shareholders disagree)
• exit rights like tag/drag

If you don’t have one, you may end up relying only on default company law and your articles - which often isn’t enough for a growing business with multiple owners.

Updated Articles Of Association

Your articles are your company’s constitution. They set out core governance rules, and they often need updating when you bring in external investors (especially if you’re creating new share classes like preference shares).

It’s common for the investment round to require:

• new share rights
• director appointment rules
• updated decision-making thresholds

This is why many investment rounds include amended Articles of Association as a completion deliverable.

Founders Agreement (If You’re Still Early-Stage)

If you’re raising while still building the business with co-founders, investors will often ask: “What happens if one founder leaves?”

A founders agreement can help deal with issues like:

• who owns what shares and whether they vest over time
• decision-making roles and responsibilities
• intellectual property ownership
• what happens if someone exits early

Getting this clear early can make investment discussions much smoother. Many startups put this in place via a Founders Agreement.

Company House Filings And Board/Shareholder Resolutions

Finally, don’t forget the admin and corporate housekeeping. Depending on the structure, you may need:

• board minutes and shareholder resolutions approving the share issue
• updated registers (such as the register of members, and potentially the PSC register if a new person becomes a PSC or their details change)
• Companies House filings (for example, return of allotment)

If you’re not yet incorporated, you may need to Register a Company before you can issue shares to investors.

Key Takeaways

• When founders ask what are investors, the practical answer is: investors provide capital in exchange for a financial return, and often rights that affect how you run your business.
• Investor types vary - from friends and family to angel investors, venture capital, corporate investors, and debt providers - and the “right” fit depends on your stage and goals.
• Investments typically come as equity (shares), debt (loans), or hybrid structures like convertible instruments, each with different legal and cashflow implications.
• Common investor rights include voting and dividend rights, reporting rights, pre-emption rights, reserved matters (consent rights), and exit protections like tag-along and drag-along rights.
• Key legal documents often include a Term Sheet, Share Subscription Agreement, Shareholders Agreement, and updated Articles of Association - and getting these drafted properly can prevent disputes later.
• Sorting out your legal foundations early makes fundraising smoother, protects your control, and gives investors confidence that your business is well-run.
