You can invest in private companies through new share subscriptions, purchases from existing shareholders, syndicates, crowdfunding platforms and funds. The route determines what you own, who makes decisions and what information and liquidity you can expect.
Private-company investing includes both very early startups and established businesses. Being privately held describes the ownership and trading context; it does not establish the company's stage or investment quality.
Choose the route that matches the exposure
| Route | What you assess | What needs particular attention |
|---|---|---|
| Direct new investment | Company, security and financing terms | Diligence, governance and future dilution |
| Syndicate or SPV | Underlying deal plus sponsor and vehicle | Fees, ownership chain and decision rights |
| Equity crowdfunding | Company offer and platform arrangement | Share class, nominee terms and disclosure |
| Secondary purchase | Existing security and sale terms | Seller ownership, transfer approvals and price |
| Private fund | Manager and investment mandate | Portfolio selection, commitments and full costs |
| Listed investment vehicle | Portfolio exposure through a listed security | Market-price discount/premium, costs and liquidity |
Employee shares or options can create private-company exposure too, with their own exercise, tax and transfer terms. Consider those holdings when deciding how much additional private risk to take.
Establish access and eligibility
Availability depends on the country, offer and route. Some direct private offerings restrict who can participate; other regulated or listed products provide broader access. A platform's admission policy should not be presented as a universal rule for the whole market.
Check the identity and role of the issuer, seller, intermediary and legal holder. Verify that the person selling shares owns or can validly transfer the security being offered. An invitation from a familiar contact is not sufficient evidence.

Evaluate the company before the access story
Understand the customer problem, evidence of demand, revenue quality, unit economics, competition and capital requirements. Assess the team through relevant experience, references and decisions, not only credentials or a persuasive presentation.
Ask what this financing enables and what must be true for the next round or self-sustaining operation. A company can be growing quickly while depending on repeated external capital to survive.
Write down the strongest reason the investment may fail. That helps prevent a scarce allocation or recognisable investor name from becoming the whole investment thesis.
Price the security you will actually own
Headline valuation is only part of the economics. Identify the share class, liquidation preference, conversion terms, option pool and expected dilution. A secondary common share and newly issued preferred share can have different rights even in the same company.
For a simple example, £100,000 invested at a £5m post-money valuation buys 2%, before further dilution and assuming straightforward equity. If later financings reduce that stake to 1.2%, a £50m equity exit would imply £600,000 of proceeds before costs, taxes and any preference effects.
Change the valuation, dilution or exit assumption and the result changes. Model those inputs rather than relying on the company's last financing headline.
Understand the ownership chain
You may own shares directly, beneficially through a nominee, or economically through an interest in another vehicle. Ask who appears on the company's register, who receives information, who votes and who can authorise a sale.
An SPV can simplify company administration by representing several investors through one holder. It also introduces its own fees and governance. Our guide to pooled investment vehicles compares these arrangements with funds and feeders.
Tax relief also follows the actual transaction and investor conditions. A UK EIS/SEIS-eligible company does not make an ordinary secondary purchase eligible for subscription relief. See EIS and SEIS.
Plan for ownership after the cheque
Private shares may be difficult to sell, even when transfers are legally permitted. A possible future IPO, acquisition or secondary market is not a promised exit date.
Keep the subscription or transfer documents, proof of ownership, reports and tax information. Track follow-on rights and any obligations to contribute more capital. When updates arrive, compare them with the assumptions behind the original decision.
A useful private investment is one you can assess and sustain at its full cost. The route should make that exposure clear, rather than make access feel easier than ownership will be.
FAQ
What is an investment syndicate?
It is a group of investors collaborating on investments, commonly with a lead coordinating the opportunity. Members may invest directly or through a pooled arrangement. Establish the actual structure and the lead's authority; the term itself does not tell you who holds the shares or controls a sale.
Can I invest in a private company with a small cheque?
Some crowdfunding offers, syndicates and investment vehicles accept smaller amounts than a direct institutional round. Minimums and eligibility differ by offer. Include fees and existing private exposure when assessing the amount: a low entry minimum does not reduce the underlying company's business risk.
Is investing through an SPV the same as buying shares directly?
The economic exposure may be similar, but the ownership and governance can differ. You may hold a beneficial interest or an interest in a vehicle that owns the security. Check information rights, voting, transfers, expenses and the distribution rules between the company and you.
How do I choose between a UK and US holding structure?
Map the issuer, sponsor, investors, asset and intended activities first. Then assess legal, tax and reporting requirements across the relevant jurisdictions. Geography is an input, not a complete answer. The separate UK and Delaware comparison explains the distinctions to investigate.
