In the early stages of a high-growth company, operating costs often far exceed revenue. Sometimes referred to as the “Valley of Death,” this precarious area of imbalance is where many startups fail. Startups often don’t qualify for traditional bank loans, which is where venture capital comes in.

Venture capital is a specific type of private equity financing provided by firms or funds to small, high-growth companies that have exceptional potential for growth. Unlike a bank loan, which you have to repay with interest, venture capital provides capital in exchange for equity ownership. About 80% of venture-backed businesses fail, so venture capitalists knowingly invest with the expectation of losing money, with the belief that the 20% that do succeed will offer a massive return on investment.

Anatomy of a Venture Capital Fund

To understand how venture capital works, it’s essential to look at the structure of a typical VC firm and the dynamics that govern its investments.

Personnel

A VC fund operates as a partnership, bringing together those with capital and those with expertise:

  • Limited Partners: LPs are money providers. They typically include large institutions like university endowments, pension funds, sovereign wealth funds, and wealthy family offices. They commit capital to the VC fund as passive investors. They provide capital but have limited liability and no say in the fund’s day-to-day management or investment.
  • General Partners: GPs are the fund managers who actively run a venture capital firm. They’re responsible for raising the funds, sourcing deals, vetting startups, making investment decisions, and managing the portfolio companies.

Both elements are essential for running a venture capital fund.

Fund Structure and Economics

VC funds are structured to seek long-term commitment and high reward, following a strict economic model. A typical VC fund operates on a 10-year lifecycle. The first five years are usually dedicated to sourcing, selecting, and investing in new portfolio companies. The next five are focused on managing the portfolio, making follow-up investments, and engineering profitable exits from portfolio companies.

GPs typically utilize the “2 and 20” rule as compensation. This means they earn a 2% management fee annually to cover the firm’s operating expenses, salaries, and research. Then, they earn 20% of the profits realized from successful exits, known as carried interest.

The entire economic model is predicated on the Power Law of Returns. A typical VC fund might invest in 20-30 companies. They expect most to fail completely. Some may return the initial capital or a small profit. A few must deliver outsized returns (like 10x, 50x, or even 100x an investment) to generate the entire fund’s profit and cover the losses of failed ventures.

Stages of Venture Investment

VC investment follows a structured lifecycle that corresponds to the maturity, risk, and valuation of the startup.

Pre-Seed / Seed Stage

In the earliest stage, capital is typically used for developing a Minimum Viable Product (MVP), validating the core idea, and conducting initial market research. The investment size is usually small, when the company valuation is low. The risk is typically highest at this time since the company often has little to no revenue and is mostly an idea and a team.

Series A

Series A is often considered the first major institutional round. A startup in a Series A funding round is expected to have achieved product market fit, proving the viability of their business model. Capital is typically used to hire key executive talent, scale the initial successful sales playbook, and prove the business model is scalable. A major institutional VC often takes the lead, sets the terms, and takes a board seat.

Series B, C, and Beyond

Later funding stages are dedicated to rapid expansion. The business model is proven, and the capital is used for aggressive market penetration, scaling infrastructure, and potentially international growth. The investments at this stage are substantial and focused on maximizing scale and preparing the company for a potential exit by the VC firm.

Why Venture Capital Is So Desirable

Venture capital is not realistic for the vast majority of companies. The reason it’s so desirable is because it demonstrates your business has massively scalable potential. Unlike debt financing, you have no obligation to repay the funds; you just forfeit part of your profit, which is a small price to pay when you’re generating a significant profit margin.

But there are other key reasons why startups are often willing to sell off a piece of the company:

  • Strategic guidance: VCs are not passive investors. General partners are often former founders or executives themselves who have deep industry experience that can be invaluable for startups.
  • Governance: The lead VC investor almost always takes a board seat. This provides high-level oversight that can help hold the founding team accountable to metrics, and ensures strong corporate governance.
  • Networks: VCs typically provide access to a vast ecosystem of potential partners, enterprise customers, executive talent, and legal/financial advisors.
  • Signal of validation: Receiving VC funding is a powerful validation signal to the broad marker. It shows future employees, customers, and partners that the company is legitimate, well-vetted, and possesses high growth potential.

Venture capital is more than just money; it’s strategic guidance for a young company that you might not be able to get otherwise.

FAQs

Venture capital is only appropriate or available to businesses with the potential for massive, rapid, and proprietary scalability. VC is so popular in the tech industry because software-as-a-service (SaaS) and other tech platforms can more easily capture a large market share quickly. Businesses with limited growth ceilings, like service agencies, local restaurants, or lifestyle businesses, will likely not have access to venture capital.

A “Unicorn” is a privately held startup company that has achieved a valuation of $1 billion or more.

The exit is when a VC fund sells its shares to realize a profit. The two primary exit strategies are selling to a larger corporation in an acquisition or an initial public offering (IPO) which brings the company to the public stock market, allowing the VC fund to sell its equity stake over time.
