Angel investor vs VC vs private equity: the differences.

The short version: an angel backs a company that's barely a company, a VC backs one that's trying to become a big one, and private equity buys one that already is. The money gets bigger and the company gets older as you move along that line. So does the appetite for losing the lot.

Press coverage tends to flatten the three into one word - "investors" - which is how a £15,000 angel cheque and a £2bn buyout end up in the same sentence. They are not the same trade. Here's how they actually differ, and where the UK tax reliefs land.

What is an angel investor?

An angel is an individual putting their own money into a young, private company - frequently the first institutional-looking cheque a founder ever sees. Cheques run from a few thousand pounds to a few hundred thousand, and the angel usually takes a small minority stake. Many are former operators or founders who bring contacts and scar tissue alongside the cash.

This is the riskiest seat in the room. The company may have a product and a handful of customers, or it may have a deck and a promise. Most angel positions go to zero or near it; the model only works because the occasional winner returns many times the original stake. It's a portfolio game played one founder at a time.

Crucially for UK readers, this is the stage the government actively subsidises. The Seed Enterprise Investment Scheme (SEIS) and the Enterprise Investment Scheme (EIS) exist precisely to nudge private individuals into backing small, higher-risk trading companies - more on the numbers below.

What is a VC, and how is it different?

A venture capitalist runs a fund. The money belongs to other people - pension funds, family offices, endowments, wealthy individuals, often the British Business Bank in the UK - who commit capital as limited partners. The VC firm is the general partner: it picks the deals, sits on boards, and is paid to do so.

That changes the maths. VCs write bigger cheques, from a few hundred thousand at seed into the millions and tens of millions at Series A and beyond. They take board seats, impose liquidation preferences and other protective terms, and expect to deploy a fund over a few years and return it over ten. Where an angel can follow a hunch, a VC answers to investors and to a fund clock.

The two fees are worth knowing because they explain a lot of behaviour. A VC firm typically charges its limited partners an annual management fee - classically around 2% of committed capital - and keeps a slice of the profits called carried interest, or carry, classically about 20% above an agreed return threshold. That's the term this newsletter is named after. An angel investing solo earns no carry; they just keep their own gains and eat their own losses.

What is private equity, then?

Private equity (PE) sits at the opposite end. PE firms also run funds with outside money, but they buy established companies - ones with real revenue and, usually, real profit. They typically take a controlling or majority stake rather than a minority, and they frequently fund the purchase partly with debt loaded onto the acquired business. That's the leveraged buyout you read about.

The thesis is different in kind. A VC is betting a tiny company becomes enormous. A PE firm is betting it can take a sound business, sharpen its operations, fix the balance sheet or bolt on acquisitions, and sell it on in three to seven years for more than it paid. Less moonshot, more operating discipline. PE managers earn carry too, on the same broad model as VC.

For an individual UK investor, PE is largely out of reach directly - the cheques and structures are institutional - and, importantly, none of the SEIS/EIS-style reliefs apply to it. Those schemes are built for small, young companies, which is the opposite of what PE buys.

How do the UK tax reliefs split them?

This is where the three diverge most sharply for a British investor, and it's the part the headlines tend to skip. The reliefs are claimed by individuals on qualifying early-stage investments, so they belong to the angel world and, by extension, to individuals backing EIS funds. You normally need to be a UK taxpayer to use them, the company has to secure HMRC advance assurance before the round, and it issues you an SEIS3 or EIS3 certificate afterwards so you can claim.

Here are the headline investor figures, current as of HMRC guidance updated 6 April 2026:

• SEIS (the very earliest stage): 50% income tax relief on up to £200,000 invested per tax year, with a three-year minimum holding period. There's a capital gains reinvestment relief worth 50% of a gain put into SEIS shares, on up to £100,000 of investment a year; gains on the shares themselves are exempt if you've held for three years and claimed the income tax relief. Loss relief is available, and the relief can be carried back to the previous tax year. On the company side, SEIS is for firms trading less than three years, with fewer than 25 full-time-equivalent staff and gross assets under £350,000 at the share issue; a company can raise up to £250,000 in total under SEIS.
• EIS (still early, slightly later): 30% income tax relief on up to £1,000,000 per tax year - or up to £2,000,000 if at least £1,000,000 of it goes into knowledge-intensive companies. Three-year minimum hold, capital gains deferral relief, gains exempt if held three years with relief claimed, loss relief, and carry-back to the previous year. On the company side EIS reaches larger firms than SEIS: broadly, gross assets up to £30m before the raise, fewer than 250 full-time-equivalent employees, investment available within seven years of first commercial sale, and annual/lifetime raise caps of up to £10m a year and £24m over the company's life (lower for certain "specified" companies, higher again for knowledge-intensive ones). These company-side figures changed in April 2026 - check the current numbers on gov.uk before relying on them.
• VCT (Venture Capital Trusts - a listed, professionally managed vehicle): 20% income tax relief on up to £200,000 per tax year, a longer five-year minimum hold, tax-free dividends and no capital gains tax on gains. Note that, unlike SEIS and EIS, loss relief is not available on a VCT.

Notice what's missing: nothing here applies to a private equity buyout. The state subsidy is pointed squarely at the small and the young. You can read the full rules on the HMRC venture capital schemes pages for EIS and the related SEIS and VCT guidance.

The money gets bigger and the company gets older as you move down the line - and so does the appetite for losing the lot.

Where the lines blur

Tidy categories, messy reality. The boundary that bends most is between angels and VCs at seed, where solo angels, angel syndicates, micro-funds and early-stage VC firms all chase and co-invest in the same rounds. An angel can join a fund-led round; a syndicate can fill out a round a VC is leading. "Super-angels" write cheques that look institutional, and some funds run scout programmes that hand individual angels a slice of fund money to deploy.

Growth equity straddles the VC/PE line too - later-stage, often minority, but in companies large enough to interest a buyout firm. The clean way to keep them straight is to ask three questions: whose money is it, how old is the company, and is the stake a minority or control? Those three answers will place almost any investor on the spectrum.

A quick word on risk and advice

None of this is a ranking. Each model carries its own risk profile, time horizon and failure rate, and "which makes the most money" has no general answer. Early-stage investing in particular can mean losing your entire stake, and the tax reliefs exist because the risk is real, not as a reason to ignore it. The Carry is editorial journalism - general information, not financial or investment advice. Before you commit capital, take advice from an FCA-regulated adviser who knows your circumstances.
