What is a Private Equity Firm – Understanding How Private Equity Works

Private equity may sound like a complex world reserved for finance experts in glass offices, but at its heart, it’s a fascinating and highly strategic part of how businesses grow, transform, and succeed. In this article, we’ll break down what a private equity firm truly is, how it operates, and why it plays such a key role in shaping the global economy — using simple language, relatable examples, and real-world context.

Private Equity Meaning – A Simple Explanation

If you’ve ever watched a struggling company suddenly bounce back stronger, chances are a private equity firm had something to do with it.
According to Investopedia, private equity (PE) refers to investments made in companies that are not publicly traded on a stock exchange. These firms use capital from investors to buy, improve, and later sell businesses for a profit.

In simpler terms, think of a private equity firm as a financial architect. It takes underperforming or high-potential companies, restructures their operations, helps them grow, and eventually sells them at a higher value.

An everyday analogy: imagine buying an old house in a great neighborhood, renovating it with care, and then selling it at a much higher price. That’s essentially what private equity firms do — except instead of houses, they deal with companies.

How Private Equity Firms Work – Step-by-Step Guide

Understanding how private equity firms work can feel tricky, but it follows a clear process. Here’s a simplified version of the private equity investment process, explained step by step.Step 1: Raising Capital

Private equity firms start by collecting money from wealthy individuals, pension funds, insurance companies, and institutional investors. This pool of money is called a private equity fund.
Each fund usually has a set lifespan (often 7–10 years) and is managed by professionals known as general partners (GPs).

You can learn more about fund structures in this CFI resource on private equity funds.

Step 2: Finding and Buying Companies

Once the fund is ready, the firm looks for companies that could benefit from financial or operational help — often undervalued or privately owned businesses.
They negotiate deals, purchase significant stakes, or buy the company outright.

A famous example: when Blackstone Group, one of the world’s largest private equity firms, bought Hilton Hotels in 2007. They improved operations and sold it later for a massive profit.

Step 3: Improving the Business

This is where the firm’s real value comes in. Private equity firms aren’t just investors — they are business builders. They often bring in experts to:

• Streamline operations

• Restructure management

• Introduce new technology or strategies

• Expand into new markets

By doing this, the firm increases the company’s value, preparing it for a successful sale later on.

Step 4: Selling for Profit (Exit Strategy)

After several years, once the business has grown and stabilized, the firm sells its stake. This can happen through an initial public offering (IPO), a sale to another company, or a secondary sale to another private equity firm.

The profits are then shared between the investors and the private equity firm, typically following an arrangement called the “2 and 20 rule” — a 2% management fee and 20% of the profits go to the firm.

You can explore how these structures work in detail at PitchBook’s guide to private equity returns.

Functions of Private Equity Firms – What They Actually Do

Private equity firms serve multiple roles in the economy. Their key functions include:

• Financing business growth: Providing the capital companies need to expand.

• Restructuring and turnaround: Helping underperforming companies regain profitability.

• Driving innovation: Supporting new business models, technologies, and management strategies.

• Creating employment: Revitalizing companies often leads to job creation.

• Enhancing shareholder value: Delivering returns for investors through long-term growth.

Private Equity vs Venture Capital – What’s the Difference?

Although often confused, private equity and venture capital (VC) are not the same.
Here’s the simple difference:

• Venture capital focuses on startups and early-stage companies with high growth potential but high risk.

• Private equity targets established businesses that need capital to expand, restructure, or go private.

You can compare their structures in this Harvard Business Review analysis.

In short, VCs invest in the dream, while PE firms invest in performance.

Types of Private Equity Investments

Private equity comes in many forms. The most common types of private equity investments include:

1. Buyouts – Acquiring majority control of a company, improving operations, then selling later.

2. Growth Capital – Investing in businesses seeking to expand or enter new markets.

3. Mezzanine Financing – A hybrid of debt and equity used for later-stage expansion.

4. Distressed or Turnaround Investments – Buying struggling companies and helping them recover.

Each investment type requires different levels of risk, management involvement, and time horizon.

Examples of Private Equity Firms

To make it more concrete, here are some examples of leading private equity firms known worldwide:

• Blackstone Group – Known for large-scale buyouts and real estate investments.

• KKR (Kohlberg Kravis Roberts) – A pioneer in leveraged buyouts.

• Carlyle Group – Active in aerospace, defense, and energy sectors.

• Apollo Global Management – Focuses on credit and private equity strategies.

These firms collectively manage trillions of dollars, shaping industries across the globe.

How Private Equity Firms Make Money

Private equity firms earn money through two main channels:

1. Management Fees – A percentage (usually 2%) of the total fund size, paid annually.

2. Carried Interest (Performance Fee) – Typically 20% of the profits made from successful investments.

You can dive deeper into this concept with Investopedia’s guide to carried interest.

Here’s a simple anecdote:
Think of it like a chef running a restaurant. The management fee is like the chef’s salary, while the carried interest is the bonus for creating a meal everyone loves. Both are essential for keeping the kitchen running smoothly.

Role of Private Equity in Business Growth

Private equity doesn’t just chase profits — it often revitalizes industries.
For example, a family-owned manufacturing company might struggle to adapt to digital tools. When a private equity firm steps in, it brings not only funding but also expert guidance and technology transformation.

The result? The company becomes more competitive, employees gain better skills, and investors benefit from increased value.

According to McKinsey & Company, private equity has been a significant driver of business innovation globally, especially in emerging markets.

Private Equity Fund Structure – Behind the Scenes

A typical private equity fund structure involves:

• Limited Partners (LPs) – Investors who provide capital.

• General Partners (GPs) – Professionals who manage the fund and make investment decisions.

• Portfolio Companies – The businesses that receive investment.

This structure ensures accountability and alignment of interests between investors and managers.

Challenges of Private Equity

Like any investment model, private equity has its challenges:

• High risk – Success depends on turning companies around.

• Long-term horizon – Returns can take years to realize.

• Limited liquidity – Investments are not easily sold like public stocks.

• Regulatory complexity – Compliance and reporting requirements are strict.

You can read about these challenges in Preqin’s private equity market report.

Despite these hurdles, private equity remains a cornerstone of global investment strategies due to its high potential for returns.

Benefits of Private Equity Firms

When managed well, private equity firms offer powerful benefits:

• Access to capital for companies that might not qualify for traditional loans.

• Strategic expertise that helps businesses grow faster.

• Diversified investment portfolios for investors.

• Long-term value creation that supports industries and economies.
