When a company begins to grow and expand, it often needs significant capital to support its operations and scale. This is where venture capital funding rounds like Series A, B, and C come into play. Most commonly something startups engage in, these rounds represent distinct stages in a company’s journey, each with its own objectives, investor types, and implications for the business.  

Why Startups Use Series Funding

Series A, B, and C funding rounds are primarily associated with startups because these companies often have innovative ideas but lack the financial resources to scale independently. Startups typically rely on outside investments to accelerate growth, develop new products, and gain a foothold in competitive markets.

Unlike established companies, startups usually cannot rely on steady revenue streams or traditional bank loans to fund their expansion. Venture capital funding, offered during these series rounds, fills this gap. In exchange for equity, startups secure the financial backing needed to bring their visions to life.

This leads to a common question: Do companies owe this money back as debt? The answer is no. Funding rounds like Series A, B, and C are equity investments, not loans. Investors provide capital in exchange for partial ownership, meaning startups are not burdened by debt repayment. However, they do relinquish some control and profits.

Another question often asked is, Why are investors willing to risk it since most startups fail? While the failure rate is high, the potential rewards are enormous. Investors diversify their portfolios, betting on multiple companies with the hope that one major success will outweigh the losses from others. A single breakthrough startup can yield exponential returns, making the risk worth taking.

Understanding Series A Funding

Series A funding is the first major round of investment a startup receives after its initial seed funding. This round is primarily focused on scaling a business model that has already shown potential. Investors, often venture capital firms, provide capital in exchange for equity, expecting a significant return as the company grows. On average, the time from seed to Series A funding is about 18 months.

Companies in Series A typically use the funds for product development, customer acquisition, and building a strong team. At this stage, the startup must present a clear strategy for monetization and demonstrate its market fit. The valuation of a company during Series A can vary, but it usually falls between $10 million and $30 million.  

According to Fundz, 47% of Series A startups have an average monthly spend of about $400k. Series A funding typically goes to new office plans, hiring sales teams and support staff or engaging in other business moves that might help to ramp sales.

Moving To Series B

Series B funding occurs when a company has proven its business model and needs to scale further. The primary goal here is to expand operations, enter new markets, and grow its customer base. Series B rounds often attract larger investments from venture capitalists and sometimes corporate investors.  A Venture Capitalist at Redpoint Ventures, Tomasz Tunguz, states that Series B funding is one of the most difficult rounds for startups.

Companies at this stage require capital to build infrastructure, enhance marketing efforts, and increase their workforce. With more established revenues and customer traction, the valuation of companies in Series B is generally higher than in Series A, often ranging from $30 million to $60 million or more.  

A few Series B investors of note include Google Ventures, New Enterprise Associates, and Khosla Ventures. When trying to raise capital as a startup, consider how similar businesses have fared. In Q3 of 2023, the median size of Series B funding rounds for companies within the U.S. on Carta, an end-to-end suite that connects business owners to manage and build equity, decreased 39.8% from Q1 2021. That median amount was $15.1M.

What’s The Difference Between Series A and Series B Funding?

The biggest difference between Series A and Series B funding in terms of investment is expectation. The progression from Series A to B is entering into a bit of an ambiguous state, especially as internal investors provide smaller doses of funding by way of bridge rounds. ‘Bridge rounds’ refers to funds that a company raises between priced ones from its existing, external investors.

While Series A should be for proving product-market fit and building a GTM strategy, and then Series B is showing that GTM in action and investing more in what’s working (and pulling out from what’s not), it’s not always that black and white. Investors across industries tend to have their own preferences and benchmarks. Some businesses might make significant progress in areas that their contemporaries don’t.

The Purpose Of Series C

Series C funding is for companies that are already successful but want to achieve even greater growth. This round is typically used for entering international markets, launching new products, or acquiring other companies.  

At this stage, investors include private equity firms, hedge funds, and investment banks. These larger institutional players are drawn to companies with proven success and a clear pathway to scaling further. Companies in Series C often have valuations exceeding $100 million, and the funding rounds can reach hundreds of millions of dollars.  

Key Differences Between Series A, B, And C

The primary distinction between these rounds lies in the company’s maturity and the investors involved. Series A focuses on developing a viable business model, Series B emphasizes scaling operations, and Series C seeks to maximize growth and market dominance. Each round builds upon the previous one, preparing the company for potential initial public offerings (IPOs) or acquisitions.  

Why Understanding Funding Rounds Matters

For entrepreneurs, understanding these funding stages is essential for navigating the growth trajectory of their businesses. For investors, the rounds offer opportunities to support companies at various stages of their development. Each round involves careful evaluation of risks, potential returns, and the long-term vision of the company.
