A private company is a business whose ownership is held by a limited group of people, such as founders, families, employees or private investors, and whose shares are not offered to the general public or traded on a stock exchange. A private incorporated company is the version of this that has been legally registered as a corporation (or, in countries such as the UK and India, a private limited company). It is a separate legal entity with shares, but those shares change hands only through private agreements.

How private companies are owned and run

“Privately held” and “private” mean the same thing. Ownership is recorded in a cap table (capitalization table) or membership register rather than spread across thousands of anonymous stockholders. Owners may be called shareholders (in a corporation), members (in an LLC), partners (in a partnership) or simply the proprietor.

Three features separate private ownership from public ownership:

1. Restricted transfers. Shareholder agreements often require board approval or give existing owners a right of first refusal before shares can be sold. There is no exchange setting a daily price, so a seller needs to find a buyer and agree on a valuation.
2. Limited disclosure. U.S. public companies file quarterly and annual reports, proxy statements and ownership changes with the SEC. A private company usually shares financial statements only with its owners, lenders and investors. Under Section 12(g) of the Securities Exchange Act, as amended by the JOBS Act of 2012, a company with more than $10 million in assets must register once its shares are held of record by 2,000 or more people, or by 500 or more non-accredited investors. That rule effectively caps how widely a private company’s stock can be held.
3. Private financing. Without access to public stock and bond markets, private firms rely on owner contributions, retained profits, bank loans and private equity or venture capital. This funding gap is a main reason large private companies eventually pursue an initial public offering (IPO).

Types of private companies

A sole proprietorship gives one person full control, but the owner’s personal assets back every business debt. Partnerships have at least two owners and share that unlimited liability for general partners. An LLC combines pass-through taxation with limited liability without formal incorporation, and the rules vary by state. S and C corporations look like public companies on paper, with shareholders and boards, but they can stay private and skip public quarterly and annual reporting. A C corporation can have an unlimited number of shareholders, while an S corporation cannot exceed 100.

Outside the U.S., the common form is the private limited company (“Ltd” in the UK, “Pvt Ltd” in India). It is owned by shareholders, its liability is limited to their investment, and it is barred from offering shares to the public.

Hypothetical example: shares in a private company

This example is illustrative and does not describe any real company. Two founders incorporate Harbor Tools Inc. as a C corporation and issue 1,000,000 shares, 500,000 each. A venture fund later buys 250,000 new shares for $1 million, which implies $4 per share and a post-money value of $5 million (1,250,000 shares × $4). The founders now own 40% each and the fund owns 20%.

None of these shares can be sold on an exchange. If one founder wants to cash out, they must find a buyer, usually get board or shareholder consent, and negotiate a price, often based on methods such as discounted cash flow or comparisons with similar businesses. The $4 figure reflects one negotiated transaction, not a continuously traded market price.

Pros and cons of staying private

Advantages

• No IPO underwriting, legal and listing costs
• Less regulatory paperwork and no public disclosure of results or strategy
• Owners keep control and can plan for the long term without quarterly market pressure. Koch Industries, for instance, has stayed in the Koch family since its founding in 1940.

Disadvantages

• Raising large sums is harder without public markets
• Shares are illiquid and difficult to value
• In unincorporated forms, or where owners personally guarantee loans, debts can fall on the owner, and a default can damage personal credit
• Disputes among partners or family members have no market mechanism to resolve them

Private vs. public companies

A public company sells shares to the public first through an IPO, after which they trade on the secondary market.

Distinctions people often confuse

• Private company vs. private sector. The private sector is every business not owned by government, which includes public companies. A listed company is “public” in the stock market sense but still part of the private sector.
• Family-owned vs. private limited. Family ownership describes who owns a firm; private limited describes its legal form. A family business can be a sole proprietorship, a private limited company or even a public company. Some listed family firms keep control through dual-class shares, which give the family’s shares more votes.
• Private company vs. private equity. Private equity is an investor type that buys stakes in companies, sometimes taking public companies private.
• Private company vs. unicorn. A unicorn is a startup valued at $1 billion or more while still private, so it is a subset of private companies.

Examples of private companies

Well-known private companies include Cargill, Koch Industries, IKEA, Deloitte and Ernst & Young. Movement works in both directions: Twitter (now X) was public until Elon Musk bought it in 2022 and took it private. Most private businesses, though, are small firms such as local shops, restaurants and contractors.

How a private company becomes public

There are three main routes:

1. IPO: new shares are sold to investors through underwriters, then listed.
2. Direct listing: existing shares are listed without raising new money through underwriters.
3. SPAC merger: the company merges with a listed special purpose acquisition company and inherits its listing.

A public company goes private in the opposite way, usually through a buyout in which an individual, management team or private equity firm purchases all outstanding public shares.

FAQs

The Bottom Line

Founders, employees and investors holding private company shares should expect limited financial disclosure and shares that are hard to sell or value. Staying private saves IPO costs and protects owner control, but it makes raising large sums harder, which is why big private firms often turn to an IPO, direct listing or SPAC merger.
