What is a private company: definition, types, differences and examples

Home » Economist » What is a private company: definition, types, differences and examples

In everyday language, we often contrast private and public companies to distinguish between privately owned organizations and state-controlled entities . This distinction in ownership influences objectives, funding methods, levels of transparency, and decision-making processes in each model.

It's also worth noting that, depending on the country, the term "private company" can refer to two related but distinct entities: on the one hand, any company that does not belong to the public sector ; on the other, a "non-listed" entity, meaning one whose shares are not traded on a stock exchange. In any case, even though they are private, these companies operate under very specific laws, sector regulations, and tax obligations .

What exactly is a private company?

A private company is an organization in which capital and control belong to individuals, families, investor groups, or other private companies . Its management is independent of the government, and its primary purpose is to generate profits through production or the provision of services in the market.

In many developed markets, the term is also used to refer to companies that are not publicly traded . In this sense, their shares or stakes are traded privately among a limited number of shareholders or investors and are not available to the general public.

Many private companies are owned by their founders or their families, although it is also common for employees and managers to hold shares . Similarly, a subsidiary of a publicly traded company may be "private" in its legal structure, but its figures are consolidated in the financial statements of the listed group due to accounting and securities regulator requirements.

Private companies are governed by the legal framework of the country in which they operate, with obligations that vary depending on the jurisdiction. For example, in the United States they are not generally required to publish annual accounts , while in Europe the transparency requirements tend to be greater. In Australia, Part 2E of the Companies Act 2001 requires listed companies to file certain documents with the Securities and Investments Commission, an obligation that does not apply to private companies.

Key characteristics of private enterprise

Although the range of cases is broad, there are common characteristics that allow us to identify these types of entities, especially when compared to public ones. Broadly speaking, these characteristics include private ownership, a focus on profitability, adherence to the law, and operational flexibility.

• Private Ownership and ControlThe capital belongs to private individuals or other non-state companies; management is organized freely within the legal framework.
• Profit-making purposeThey are born to compete and make profits; their success is measured in economic results and value creation for owners.
• Subject to regulationThey must pay taxes, comply with labor, competition and sector regulations (health, education, energy, telecommunications, etc.).
• Transparency and reportingIn general, the obligation to disclose information is more limited than in listed companies; in the EU it is usually more demanding than in the US, where many private companies do not publish their financial statements.
• Partner restrictionsIn the U.S., the Securities Exchange Act of 1934 (section 12(g)) requires registration and reporting when certain thresholds of shareholders and assets are exceeded, traditionally 2.000 shareholders (or 500 non-accredited shareholders). The Investment Company Act of 1940 requires registration for funds with more than 100 forks, among other criteria.
• Strategic flexibilityBy not depending on broad shareholder assemblies or political objectives, management can focus on the long term and react quickly.

From a historical perspective, modern private enterprises were consolidated following the Renaissance and the rise of international trade, and later the Industrial Revolution. Monarchical and imperial states leveraged these structures as engines of economic and political expansion during the Mercantilist period, paving the way for contemporary capitalism.

Types of private companies

Sole proprietorship . This is a business owned by a single proprietor. These are simple structures for starting a business, with the owner having complete control and, generally, unlimited liability for debts and obligations. Although the informal definition is sometimes vague, the key point is that this type of business participates in the production or exchange of goods and services and operates directly in the market.

Partnership or company . Two or more people come together to operate for profit. They can be general partnerships, limited liability companies, or companies with limited liability for the partners, depending on local regulations. In partnerships, liability for debts can be total and unlimited; in limited liability companies, it is limited to the amount of the investment.

Limited liability company (LLC) . Protects the personal assets of the partners: each is liable only up to the limit of their share. It is common when it is desired to clearly separate the legal personality of the company from that of its members and to have flexible rules for internal organization.

Public limited company or corporation . An entity with its own legal personality and a capital structure divided into shares. It may have limited liability and anywhere from a few shareholders to thousands, and may or may not be publicly traded. Effective control depends on shareholding and is exercised through the board of directors and governing bodies.

As an additional note, corporate business models are also used in the state sector through state-owned enterprises , whose majority shareholder is the State; their purpose prioritizes the general interest over profitability.

Differences between private and public companies

The main boundary is ownership: if the majority of the capital is held by private individuals, we call it private; if the state owns it, it is public. From there, the objectives, incentives, and procedures change.

• Ownership and purposeThe private sector seeks to maximize profits; the public sector may prioritize social objectives, universal access, stability, or the defense of strategic sectors.
• decision makingIn the private sector, the corporate governing body (board of directors, management) makes the decisions in the interest of the shareholders. In the public sector, the initiative comes from the State, which sets objectives and controls the activity.
• Resource ManagementPrivate companies usually have more operational freedom; in public companies, the sale of assets or relevant strategic changes require government approvals.
• FinanceThe private sector is financed with Sources of funding such as private capital, bank debt or markets; the public sector, with state budgets, taxes and also with its own income from its activity.
• Transparency and oversightPublic institutions are subject to more intense political and administrative control; private institutions report within the limits required by law and, if they are publicly traded, under [a specific system/regulation]. market demands.

The distinction is not absolute. There are mixed enterprises with public and private capital, as well as processes of nationalization (private becoming public) and privatization (public being transferred to private ownership). Some debates emphasize that private companies tend to produce what has the highest profit margin rather than what is "most necessary" for a country; in practice, governments correct these potential market failures through regulation, taxes, and direct provision of services where appropriate.

Corporate governance: entrepreneurial risk and entrepreneurial decision

In large companies, especially those listed on the stock exchange, a distinction is usually made between two roles. The risk-taking investor is the shareholder who contributes capital and assumes the variability of the dividend and share price depending on performance and expectations.

The decision-making body is the senior management team (president, board members, and managers) that designs and executes the strategy. It must be accountable to the shareholders, who decide whether or not to maintain their trust. Senior management must carefully distinguish between the concepts of uncertainty and risk : undertaking a venture without knowing the probabilities is uncertainty; acting with known probabilities is risk, and both influence how a private company is governed.

Economic and social role, with a focus on developing countries

Private companies form the core of the private sector and are the engine of growth, employment, and innovation. They invest in R&D, generate new products and services, and raise the quality of life through competition and efficiency.

In developing countries, their role is even more visible: they contribute revenue through taxes and fees , and in extractive activities they add royalties, resources that finance infrastructure and public policies that attract investment and improve services.

However, these countries also face dilemmas. When ownership of strategic sectors (energy, water, transportation) falls into private hands without adequate regulation, access or quality for the population can suffer. Therefore, states adjust regulatory frameworks, establish essential public services , and, where appropriate, operate state-owned enterprises.

The recent history of some Latin American countries illustrates protectionist models where part of the business sector became closely integrated with the state. In Colombia, for example, entities such as SENA and ICBF , as well as compensation funds, were created to promote business competitiveness and fulfill social missions (training, welfare, and child protection).

In addition to their economic role, many private companies voluntarily promote social responsibility programs and public-private partnerships to improve services, support education, or modernize infrastructure, complementing state action.

Examples of private companies

If we use the broad definition of "private" as "non-state," this includes both giant corporations and SMEs; lists of the largest private companies exist that illustrate the sector's landscape. Among the best-known globally are Amazon, Costco, Alphabet (Google), Toyota, Samsung Electronics, AT&T, ExxonMobil, Foxconn, and Mercedes-Benz Group . All of them operate with non-state capital and compete in open markets.

In the Hispanic and regional sphere, we can also mention BBVA (banking), LATAM Airlines (aviation), Anagrama Publishing House (publishing), and Hyundai Motor Company in Asia, which illustrate different sectors and scales. Some are publicly traded and others are not, but in all cases, we are talking about privately owned companies.

For those seeking curiosity and scale, specialized publications like Forbes periodically compile lists of the largest private companies in the United States, useful for taking the pulse of the competitive landscape and the fastest-growing sectors.

Legal and market aspects: to list or not to list

The line between “private” and “public” can refer to stock market listing. In markets like the United States, a “public company” means that the company is publicly traded and must comply with strict disclosure rules. A “private company” is one that is not publicly traded and, therefore, has fewer obligations to provide information to the general public.

This does not mean operating without controls: there are thresholds (such as those in section 12(g) of the Exchange Act of 1934) that require registration when certain numbers of holders and assets are exceeded, and investment companies fall under the umbrella of the Investment Company Act of 1940 when they exceed limits such as 100 investors.

In Europe, even unlisted companies are generally required to file accounts and comply with accounting and auditing standards. And in Australia, listed companies must submit documentation to the Securities and Investments Commission (Part 2E of the Companies Act 2001), a requirement that does not apply to private companies.

Another common nuance: subsidiaries of listed groups may be private companies from a legal point of view, but their assets, liabilities and activities are included in the consolidated reports of the parent company, as required by accounting standards and securities regulators.

Entrepreneurship, training and banking for businesses

Anyone wishing to start a business can choose the structure that best suits their project (sole proprietorship, limited liability company, corporation, etc.). Entrepreneurship is the most common entry point into the private sector, and it's advisable to seek advice to choose the structure with the appropriate taxation, liability, and governance.

For management in the public sector, there are specialized postgraduate programs in public administration and management , useful for understanding how private companies interact with the government. On the financial side, banks offer business accounts and services that facilitate collections, payments, and cash flow management, essential for scaling successfully.

Before concluding, it's worth highlighting a couple of practical points: in most jurisdictions, private companies have fewer disclosure obligations than publicly traded companies; and when they are not publicly traded, they can protect sensitive information from competitors, preserving the trust of customers and stakeholders. In return, they must strictly comply with tax, labor, and industry regulations, and adopt good governance and compliance practices .

All of the above paints a clear picture: private companies, whether publicly traded or not, small or multinational, drive the market economy, compete to offer valuable goods and services , and coordinate with the government through taxes, regulations, and, where appropriate, collaboration. Choosing the right legal structure, governing wisely, and understanding each country's legal framework makes the difference between a project that merely works and one that endures and grows.
