Taking a company public is one of the biggest decisions a business can make. Through an initial public offering (IPO), a private company sells its shares to the public for the first time and lists them on a stock exchange.
A listing brings prestige, but it is about much more than reputation. It gives a company access to capital and lets early investors turn their shares into cash. It also brings costs, scrutiny and pressures that private companies never face.
For startups, the IPO has a special role. Venture capital and other early investors do not plan to stay forever. An IPO is one of the main ways they exit and realize the returns on their investment.
This article sets out the pros and cons of going public, explains how an IPO works as an exit route for startup investors, and looks at the alternatives.
How an IPO Works
An IPO usually follows these steps:
- Preparation: The company gets its finances, governance and reporting in order, often a year or more in advance.
- Choosing bankers: It appoints investment banks to manage the offer, known as underwriters.
- Due diligence and filing: The bankers, lawyers and auditors examine the business, and the company files a detailed prospectus with the regulator, such as the SEC in the US or SEBI in India.
- Roadshow and pricing: Management presents the company to large investors, and the bankers gauge demand to set the share price.
- Listing: The shares are sold to investors and begin trading on the exchange.
- Life as a public company: From then on, the company must report its results regularly and follow the exchange’s rules.
Advantages of Going Public
-
Easier Access to Capital
The most obvious benefit is easier access to capital. Raising money as a private company is hard, partly because investors who buy private shares are locked in until the company is sold or goes public.
Public shares, by contrast, trade on an active market. Investors can buy and sell whenever they want, and this liquidity makes them more willing to invest. Once listed, a company can also return to the market to raise more money through a follow-on offering, without having to find and pitch to new investors one by one.
-
Higher Valuations
When shares are listed, many investors compete to own them, which can push prices up. Public companies often trade at higher valuations than similar private ones, because their shares are easier to sell.
Sometimes prices rise too far and a bubble forms. Other times, prices fall after the listing. But for many successful businesses, going public puts a much higher price tag on the company. The main beneficiaries are the founders and early investors.
-
Liquidity and an Exit for Investors
An IPO gives every shareholder, including founders, employees with stock options and venture capitalists, a way to turn their shares into cash. They do not have to wait for the whole company to be sold. They can sell their own shares when they choose, subject to any lock-up period.
-
Reputation and Brand Awareness
Exchanges have minimum listing requirements, so a listing signals that a company has reached a certain size and standard. Customers, suppliers and potential employees often view listed companies with more trust.
An IPO also attracts a great deal of media attention, which can raise the company’s profile and help its sales.
-
Shares as a Currency
Listed companies can use their shares to buy other businesses and to reward employees with stock options that have a clear market value. This helps them grow and attract talent.
Disadvantages of Going Public
-
Loss of Control
Before an IPO, founders can often make decisions on their own. Afterwards, major decisions may need the approval of the board and shareholders, and the company must follow strict procedures.
If founders sell too much of their stake, they may lose control altogether. In the worst case, a competitor or investor can buy a majority of the shares on the market and take over the company against management’s wishes.
Some founders protect themselves with dual-class shares, which give their shares extra voting rights. Google (Alphabet) and Meta are well-known examples, and India also allows shares with superior voting rights for certain tech companies.
-
Loss of Privacy
Public companies must publish their financial results and disclose important information regularly. Competitors can study these reports to work out the company’s strategy, costs and margins. A company whose edge depends on keeping information private can lose that edge.
-
Pressure for Short-Term Performance
Public companies report their results every quarter, and the stock market has little patience for disappointing numbers. Some long-term strategies, such as heavy investment in research, hurt profits in the short run.
This pressure can push management to focus on the next quarter rather than the next decade. Startups, which often put growth ahead of profit, can find the shift especially hard.
-
High Costs
Going public is expensive. Underwriting fees alone often take a few percent of the money raised, and in the US commonly around 4% to 7% for smaller offerings. There are also legal, accounting and exchange fees.
The costs continue after the listing. Public companies need regular audits, more detailed reporting, investor relations staff and often new board members and compliance officers.
-
Market Risk
The timing of an IPO depends on market conditions. If markets fall, a company may have to delay its listing or accept a lower price. After listing, the share price can be volatile, and a falling price can hurt morale and the company’s reputation.

IPO as an Exit Route for Startups
A typical successful startup raises money from angel investors and venture capital funds in several rounds. These investors provide capital to help the company grow, but they expect to cash out within several years.
When the business matures, the company itself rarely has enough money to buy back their shares. An IPO solves this problem by letting the investors sell their shares to the public.
Why Startup Investors Like IPOs
- Higher valuations: Successful startups can often sell shares at high prices in an IPO, especially when there is excitement about the company.
- Partial exits: Investors do not have to sell everything at once. They can sell some shares in the IPO and the rest over time.
- Ongoing access to capital: The company can raise more money later through follow-on offerings.
Lock-Up Periods
Investors usually cannot sell immediately. Most IPOs include a lock-up period, often six months in the US, during which existing shareholders agree not to sell. Regulators may set their own rules too. In India, for example, SEBI rules require promoters to hold at least 20% of the post-issue capital as the minimum promoters’ contribution. This stake is locked in, generally for 18 months, or three years where the issue funds capital expenditure, and any promoter holding above it is locked in for a shorter period. Lock-ups prevent a flood of shares from hitting the market and crashing the price.
Challenges for Startups
- Pressure to show profits: Private investors may accept years of losses in pursuit of growth. Public markets are often less patient and focus more on cash flow and profitability.
- Compliance costs: Startups must suddenly meet the reporting and governance standards of public companies, which can mean hiring lawyers, auditors and a compliance team.
- Slower decisions: Disclosure rules and the need for board and shareholder approval can slow a fast-moving startup down.
Is Your Startup Ready for an IPO? A Readiness Checklist
Moving from private venture funding to public markets means meeting demanding operational, financial and regulatory standards. Companies can test their readiness against these five areas.
| Area | What public markets expect | If you are not there yet |
|---|---|---|
| Predictable revenue | Several consecutive quarters (often six to eight) of meeting internal forecasts within a narrow margin | Delay the listing; public markets punish missed guidance |
| Financial reporting and audit | Two to three years of audited accounts under GAAP or IFRS, from a reputable audit firm (exact requirements vary by exchange) | Move from startup bookkeeping to full statutory accounting |
| Internal controls | Documented controls over financial reporting with no material weaknesses (in the US, as required by the Sarbanes-Oxley Act) | Set up an internal audit function and a proper ERP system |
| Governance | A board with enough independent directors, plus independent audit and pay committees | Move away from a purely founder-controlled board |
| Margins and path to profit | Defensible gross margins and a clear path to positive operating cash flow | Consider private funding rounds or a sale instead of an IPO |
Alternatives to an IPO
An IPO is not the only way for startup investors to exit.
| Alternative | How it works | Main trade-off |
|---|---|---|
| Trade sale (acquisition) | Another company buys the startup O | ften quicker and simpler, but founders usually lose independence |
| Secondary sale | Investors sell their shares privately to other investors | Keeps the company private, but buyers may demand a discount |
| Direct listing | Shares start trading without a traditional IPO or new money raised | Lower fees, but no new capital and less price support |
| SPAC merger | The company merges with a listed shell company set up to buy a business | Can be faster, but has faced criticism; in the US, SEC rules effective in 2024 brought SPAC disclosures and liability closer to those of a traditional IPO |
| Management buyout | The founders or managers buy out the investors | Keeps control, but needs financing |
Conclusion
Going public gives a company access to capital, higher valuations, liquidity for its shareholders and a stronger public profile. For startups, it is one of the most popular ways for early investors to exit.
It also brings loss of control, loss of privacy, short-term pressure and high costs. The right choice depends on the company’s stage, its need for capital, its founders’ wish for control and the state of the markets. Many successful companies decide that the benefits are worth the costs; others choose to stay private or exit through a sale instead.
