Angel investing means buying shares in very early-stage private companies. These investments are very high risk, usually illiquid and you could lose all the money you invest.
Different networks provide very different levels of deal screening, syndication, reporting and investment administration.

Common equity with rights depending on the articles and share class.
Preference shares
May include preferential rights on liquidation or dividends.
Convertible instruments
Instruments that may convert into shares later under stated terms.
Nominee / SPV interest
You may hold via a nominee or special-purpose vehicle rather than direct registration.

How angel investing typically works
Step 1
Find an opportunity
Through a network, syndicate, platform or introduction.
Step 2
Review the founders
Assess founder-market fit, integrity and execution ability.
Step 3
Review financials and market
Understand traction, unit economics and market context.
Step 4
Review valuation and terms
Price, share class and shareholder rights all matter.
Step 5
Complete due diligence
Network screening should supplement, not replace, your own assessment.
Step 6
Subscribe for shares
Complete legal documents and transfer funds.
Step 7
Support / monitor the company
Reporting quality and information rights vary.
Step 8
Exit — if one occurs
Exit may be an acquisition, secondary sale, IPO or no return at all.
What should you assess in the founding team?
Founder-market fit
Why these founders for this problem and market.
Execution history
Evidence of delivery, not just vision.
Complementary skills
Whether the team covers product, commercial and operational needs.
Founder ownership
Whether founders retain enough incentive after the round.
Commitment
Full-time focus and personal stake in the outcome.
Integrity & transparency
How clearly risks and uncertainties are disclosed.
Key-person dependence
What happens if a founder leaves.
Coachability
How the team responds to challenge and investor input.
Hiring ability
Whether founders can recruit the people required to scale.
Cap table alignment
Whether ownership and incentives remain coherent after the round.
Succession / governance
Whether governance can evolve as the company grows.
Valuation
Is the valuation reasonable?
Private-company valuation determines how much ownership your investment buys.
Pre-money valuation
£4m
New capital
£1m
Post-money valuation
£5m
Angel investment
£25,000
Approximate ownership
0.5% before future dilution
Illustrative example only. A high valuation can reduce future return potential if company growth does not justify the price paid.
Ownership
How future funding can dilute your stake
Early-stage companies often raise several funding rounds. If new shares are issued and you do not participate, your percentage ownership may fall.
Initial ownership
1.00%
After Series A
0.75%
After Series B
0.55%
Illustrative ownership path: 1.00% → 0.55%
Illustrative example only. Dilution is not automatically negative if the company becomes much more valuable, but your ownership percentage changes.
What to check in the term sheet
Valuation
What ownership your capital buys today.
Share class
Ordinary, preference or other rights attached.
Liquidation preference
Who gets paid first if the company is sold.
Voting rights
Whether you can influence key decisions.
Pre-emption rights
Ability to maintain ownership in later rounds.
Anti-dilution
Protection if later rounds price lower.
Information rights
What reporting you receive.
Drag / tag rights
How exits can be forced or joined.
Board rights
Whether investors get board or observer seats.
Convertible terms
Conversion price, discount and caps where used.
Headline valuation is only one part of the economics.

Tax schemes
How EIS and SEIS can relate to angel investing
Angel investing is an investment approach. EIS and SEIS are tax schemes. They are not the same thing.
EIS
Some qualifying angel investments may be eligible for Enterprise Investment Scheme relief under current rules, subject to investor and company conditions.
SEIS
Some very early-stage qualifying investments may be eligible for Seed Enterprise Investment Scheme relief under current rules, subject to investor and company conditions.
Advance Assurance
A company may seek an indication from HMRC that a proposed investment may meet relevant scheme conditions based on the information submitted.
Tax relief may apply where eligible — it is not automatic and does not make the company safer.
Advance Assurance does not guarantee final investor tax relief and is not an endorsement of investment quality.
An angel investment may qualify for EIS or SEIS, but many angel investments do not.
This is illustrative only. More investments do not guarantee better outcomes. Also consider sector, stage, vintage and follow-on reserve.
Future funding
Should investors reserve money for follow-on rounds?
Some angel investors keep part of their planned allocation available for future rounds in existing portfolio companies.
Potential use
Support stronger portfolio companies or maintain ownership.
Dilution
Participating may help reduce dilution.
Additional risk
It also means committing more capital to the same private companies.
No obligation
You are not guaranteed access to future rounds.
Follow-on reserves are an educational concept, not a recommendation that every investor should reserve capital.
Key angel-investing risks
Total-loss risk
The company can fail completely.
Extreme illiquidity
There may be no buyer for the shares for years.
Founder risk
The business may depend heavily on a small founding team.
Funding risk
The company may run out of cash or fail to raise the next round.
Valuation risk
Early-stage valuations are highly uncertain.
Dilution risk
Future funding can materially reduce percentage ownership.
Concentration risk
A small angel portfolio can depend on only a few company outcomes.
Information risk
Private companies disclose much less than listed businesses.
Legal / share-class risk
Different investor rights and preferences can materially affect returns.

Common questions about angel investing
Angel investing is direct investment by individual private investors into early-stage private companies, typically in exchange for equity. Some angels also provide mentoring, introductions or strategic support. It is highly illiquid and high risk, and you could lose all of your investment.
Investors find opportunities through networks, syndicates, platforms or contacts, review the company and terms, invest (directly, via nominee or through a syndicate), may support the founders, and wait for a potential exit. An exit may take many years or never occur.
Minimum investments vary by network, syndicate, platform and deal. Some routes may have lower entry points while others require substantially more capital. Always check the specific opportunity and only invest money you can afford to lose.
Yes. Angel investing is generally very high risk. Early-stage private companies can fail completely, shares are usually extremely illiquid, and returns are uncertain. Tax relief does not make the company safer.
Yes. Total loss is possible. Company failure, extreme illiquidity, funding shortfalls and founder risk can wipe out an angel investment.
Potential paths include a trade sale, secondary share sale, IPO or (less commonly) a buyback. Many early-stage companies never deliver a return. Dividends are uncommon while companies reinvest for growth.
Often for many years. Private-company shares may have no ready buyer. Plan for a long and uncertain holding period rather than a short-term investment.
Usually only with difficulty. There may be no secondary market, and any sale may require company or shareholder consent. Do not assume you can exit when you want.
A syndicate is a group of investors investing alongside a lead angel or organiser. The lead may coordinate due diligence and terms, while investors participate under the syndicate or SPV structure. Fees and rights vary by arrangement.
An angel network introduces investors to founders and private-company opportunities. Networks differ in deal flow, screening, fees, eligibility and how much due diligence they carry out.
A lead angel is typically an experienced investor who helps source or evaluate a deal, may negotiate terms, and may invest alongside syndicate members. A lead does not remove company-level investment risk.
Due diligence is the process of checking founders, the business model, financials, legal documents, ownership, rights and risks before investing. Network or platform checks can help, but investors should still understand the risks themselves.
Consider founder-market fit, execution history, complementary skills, ownership incentives, full-time commitment, integrity and key-person dependence. For very early-stage businesses, team quality can be as important as the product.
Product-market fit means real customers value the product enough to use or pay for it on a repeatable basis. Early-stage companies may not yet have proven fit, so treat growth projections carefully.
Burn rate is how quickly the company is spending cash each month. High burn without matching progress can shorten runway and increase funding risk.
Cash runway is how many months the company could continue operating at its current burn rate before needing additional funding. Short runway can create pressure for dilutive follow-on rounds.
Pre-money valuation is the company’s agreed value before new investment is added in a funding round.
Post-money valuation is typically the pre-money valuation plus the new money raised in that round. It helps estimate ownership before future dilution.
Dilution happens when a company issues more shares in later rounds. Your percentage ownership can fall unless you participate or have relevant pre-emption rights. Dilution is not automatically negative if the company becomes much more valuable.
A liquidation preference can entitle certain share classes to receive proceeds before ordinary shareholders in specified exit or liquidation scenarios. Economic outcomes can differ materially between share classes.
Pre-emption rights may allow existing investors to participate in future share issues so their ownership is not diluted as quickly. Availability varies by deal and share class.
A convertible note is typically debt that may convert into equity later under specified conditions such as a future funding round, valuation cap, discount or maturity terms. Always read the conversion terms.
An advance subscription agreement provides capital now for shares to be issued later under agreed terms. It is not the same as receiving ordinary shares at the time of investment.
Some qualifying angel investments may be eligible for EIS under current UK rules, subject to investor and company conditions. Eligibility is not automatic. See our EIS page and official GOV.UK guidance for current rules.
Some very early-stage qualifying investments may be eligible for SEIS under current UK rules, subject to investor and company conditions. Eligibility is not automatic. See our SEIS page and official GOV.UK guidance for current rules.
No. Advance Assurance does not guarantee final investor tax relief and is not an endorsement of investment quality. Final relief depends on the company and investor continuing to meet the relevant conditions.
Angel investing is often relationship-led direct investing or syndicate participation, sometimes with an active investor role. Equity crowdfunding is typically platform-led fundraising with broader participation and a more standardised process. The categories can overlap.
Angel investing is an investment approach. EIS and SEIS are tax schemes that may apply to qualifying investments. An angel investment may qualify for EIS or SEIS, but many do not, and tax relief does not make the company safer.
Angel investors are typically individuals using personal capital, often at earlier or smaller rounds. Venture capital usually involves professional fund managers investing pooled capital with institutional processes and greater follow-on capacity.
Angel investing usually targets early-stage founder-led companies with minority stakes and very high failure risk. Private equity more often involves manager-led funds investing in more mature businesses, sometimes using leverage and longer institutional fund structures.
Where relevant, check the platform, network, syndicate or intermediary and its permissions on the FCA Register. FCA authorisation of an intermediary does not make the underlying start-up safe or guarantee investment performance.
Do not assume ordinary private-company investment losses are covered by the FSCS simply because a regulated intermediary is involved. Check the specific arrangement.
