Headlines about fast-growing private companies like major startups before they go public lead many people to wonder how to invest before an IPO. It is possible in some cases, but it works very differently from buying public stocks and carries much greater risk. This guide from The Finance Reveal explains how to invest in private companies, part of our Investing section. This is general education, not investment advice, and private investments are high-risk and can result in the total loss of your money.

How Private Investing Differs

Unlike public companies, whose shares trade freely on stock exchanges, private companies are not listed, so you cannot simply buy their stock through a regular brokerage. Investing in them means acquiring an ownership stake through other channels, and the differences from public investing are significant. Private investments are typically illiquid, meaning you may not be able to sell your stake for years, if at all, since there is no ready market. They also tend to be far riskier, since many private companies and startups fail, and information about them is less transparent than the detailed disclosures public companies must provide.

Because of these risks, private investing has historically been oriented toward those who can afford to lose the money and who understand what they are getting into. In many places, certain private offerings are limited to accredited investors, a legal category based on income or wealth thresholds designed to ensure participants can bear the risk. This is a world apart from the diversified, liquid approach our guide to what to know before you start investing describes, and it should never come at the expense of your financial foundation.

Ways People Access Private Companies

There are several routes people use to invest in private businesses. The table below summarizes common ones.

One route is angel investing, where individuals directly back early-stage startups, often requiring significant money and connections. A more accessible option that has grown in recent years is equity crowdfunding, where online platforms let many people invest smaller amounts in private companies, though the risks remain high. Investing through venture capital or private equity funds is another path, but these are typically aimed at wealthy or institutional investors and often have high minimums. Some private company shares, including those of well-known late-stage startups, occasionally become available through specialized secondary markets or funds that hold pre-IPO shares, where permitted and usually still limited to qualified investors. Each route has its own requirements, risks, and access barriers, so understanding the specific structure and your eligibility matters, a caution that echoes the mistakes our guide to common investing mistakes warns against.

Approaching It Wisely

If you are considering investing in a private company, the most important principle is to only risk money you can afford to lose entirely, since the possibility of losing your whole investment is very real. Private investments should generally represent, at most, a small portion of an already solid, diversified portfolio, not a replacement for the foundational investing that builds long-term wealth. It is also essential to research thoroughly, understand exactly what you are buying and its terms, be realistic that most startups do not become the next big success, and be wary of anything that sounds too good to be true, since this space attracts scams and hype.

For most people, the sensible reality is that the tried-and-true path of diversified, low-cost investing in public markets is where the bulk of their money belongs, with private investing reserved, if at all, for a small, carefully considered slice once the fundamentals are in place. The essential message is that investing in private companies is possible through routes like angel investing, equity crowdfunding, private funds, and certain secondary markets, but it is illiquid, high-risk, often restricted to qualified investors, and carries a real chance of total loss. Approached only with money you can afford to lose, after thorough research, and as a small part of a broader plan, it is an area to treat with great caution rather than as a shortcut to riches.

Frequently Asked Questions

How do you invest in private companies?

Because private companies are not listed on stock exchanges, you cannot buy their shares through a regular brokerage. Instead, people use routes like angel investing in early startups, equity crowdfunding platforms, venture capital or private equity funds, and specialized secondary markets that sometimes offer pre-IPO shares. Each has its own requirements, and many are limited to accredited investors. All carry high risk, illiquidity, and less transparency than public investing.

Can anyone invest before an IPO?

Not always. In many places, certain private and pre-IPO offerings are restricted to accredited investors, a legal category based on income or wealth thresholds meant to ensure participants can bear the risk. Some equity crowdfunding options are more broadly accessible, but they remain high-risk. Access to shares of well-known late-stage startups is often limited and competitive. Eligibility depends on the offering and your location, so it is important to check the specific rules.

Is investing in startups a good idea?

It can be rewarding but is very high-risk, since many startups fail and you could lose your entire investment. Private investments are also illiquid, meaning you may be unable to sell for years. For these reasons, they are generally suitable only as a small portion of an already diversified portfolio, using money you can afford to lose entirely. For most people, diversified, low-cost public market investing should remain the core of their strategy.

What are the risks of private company investing?

The main risks are a high chance of total loss, since many private companies fail; illiquidity, since you often cannot sell your stake for years due to the lack of a ready market; and limited transparency, since private companies disclose far less than public ones. The space also attracts hype and scams. These risks are why private investing is often restricted to qualified investors and should only ever involve money you can afford to lose.

The Bottom Line

Investing in private companies is possible, but it works very differently from buying public stocks and carries far greater risk. Because private companies are not listed on exchanges, you cannot buy their shares through a regular brokerage; instead, people use routes like angel investing, equity crowdfunding platforms, venture capital or private equity funds, and specialized secondary markets that sometimes offer pre-IPO shares. These investments are typically illiquid, meaning you may be unable to sell for years, much riskier since many startups fail, and less transparent than public companies, and many are legally restricted to accredited investors who meet income or wealth thresholds. The guiding principles are to invest only money you can afford to lose entirely, to keep private investments to a small slice of an already diversified portfolio rather than a substitute for foundational investing, to research thoroughly and understand exactly what you are buying, and to stay wary of hype and scams, since the chance of total loss is very real. For most people, the core of their wealth-building belongs in diversified, low-cost public market investing, with private investing reserved, if at all, for a small and carefully considered portion once the fundamentals are solid. Treated with great caution rather than as a shortcut, it is an advanced area that demands eligibility, research, and risk tolerance.
