Series A vs. Series B: Definition and Differences

The entire model of startup growth is built around fundraising , with different rounds marking distinct stages of a company's development. Early-stage startups typically begin with pre-seed and seed funding to build their product and validate market demand. As startups gain traction, they move into Series A and Series B rounds, which are designed to fuel expansion and scaling efforts. Each round represents a step toward maturity, however, as the rounds pass by and investors are brought in, it's difficult to differentiate what's unique about one round or the other.

Understanding the differences between these stages is crucial for founders and investors alike. In this article, we'll explore the distinctive characteristics of series A and series B, often the more blurry and misunderstood fundraising stages.

Before we start, it's useful to get familiarized with all the stages of funding in a startup's lifetime. Check out our cheat sheet where we outline what each stage of startup funding entails.

How Do Fundraising Rounds Work?

Fundraising rounds are the stages through which startups raise capital to fuel their growth, normally from private equity firms, angel investors, and other types of venture capitalists. Each round corresponding to a different phase in the company’s development, and are divided based on a company’s maturity and financial needs. The pre-seed and seed rounds are the earliest stages of funding used to develop ideas, prototypes, and achieve product-market fit. As the startup progresses, it moves into Series A, where the focus shifts to scaling and refining the business model. Series B follows, where additional funding drives expansion into new markets and helps scale operations more aggressively. Each round targets specific goals and involves different types of investors, although the amounts raised, kinds of potential investors attracted, and the conditions of the deals start varying considerably at these stages. This is why it's useful for rookie startup founders to get familiarized with the differences between each development stage.

Key Definitions: Understanding Series A and Series B

The two primary rounds after seed funding are known as Series A and Series B. Understanding the nuances of these funding stages is essential for founders, investors, and those looking to enter the startup ecosystem.

What is Series A?

Series A funding is normally the first significant round of financing that a startup seeks after seed funding. This stage occurs when a company has developed a solid business model, achieved some level of market traction with a viable product, and needs additional capital to scale its operations and establish a robust presence in its target market. Instead of individual investors, this stage primarily targets more formalized institutions such as venture capital firms that specialize in later-stage funding. The goal of Series A funding is to optimize the product offerings and expand the company's market reach while also building a base for future growth.

Key Features of Series A:

• Investment Amount: Series A funding rounds can vary significantly, but generally range from $2 million to $15 million or more, depending on the business model and market potential. Variations of millions of dollars are common.
• Valuation: Companies in this stage often see valuations between $10 million and $30 million, but this can depend largely on the industry and traction.
• Focus: The emphasis is on demonstrating that your startup is poised for scaling and achieving exponential growth after a capital injection from new investments. Either through talent acquisition or executing a business strategy to scale faster, investors expect accelerated revenue growth after this round is closed.

What is Series B?

Series B funding represents the next major round after Series A, typically sought once a startup has proven its business model and established significant traction. At this stage, startups are no longer just aiming for survival; they are focused on building a sustainable business model that can expand its position aggressively and keep up with market demand. Series B is not just about growth—it's also about scaling up the business infrastructure, which necessitates a higher level of investment to handle more complex business challenges and strategies.

Key Features of Series B:

• Investment Amount: Companies typically seek larger sums during Series B funding rounds, ranging from $10 million to $50 million or more, depending on the startup's needs and market opportunity. However, it's not unheard of to raise smaller rounds from previous investors to achieve specific business goals at this and subsequent funding stages.
• Valuation: At this stage, valuations generally increase significantly, often falling between $30 million and $100 million. This increase is due to the established track record in the market and the potential for further growth.
• Focus: The focus shifts from merely scaling to building upon an already thriving operation. Startups usually employ Series B funding to refine operations, hire more talent, increase marketing efforts, and potentially expand into new markets or product lines. Investors will expect a clear strategy that outlines not only how the business intends to execute these projects, but the expected return on investment further down the line. Exit scenarios become a topic of discussion at this point.

Pitfalls to Watch Out For During Series A and B

Timing is especially important during the transition between the seed funding stage, and Series A and beyond. It's a critical period in a startup's life: by the time you start pitching your Series A, you should product development and business development must be solved. If you haven't cracked the market you're tackling or don't have an impressive amount of traction, institutional investors won't be impressed by your pitch, and venture capital will be hard to come by.

These rounds are for expanding your market share or breaking into secondary markets. Prospective investors won't provide capital for expansion of your customer base - that's what your previous funding rounds should've accomplished.

Investors and venture capital firms that invest at these stages are highly specialized and have a lot of experience in their portfolios, so the smallest indication of a potential issue will raise all alarms for them, likely costing you a deal with them. Problems such as conflicts within the team or inexperienced team members, negative growth KPIs for prolonged periods of time or a less than ideal product-market fit are to be solved, or altogether avoided, before starting a Series A fundraising round.

Conclusion

In summary, Series A and Series B funding rounds serve different purposes in a startup's growth journey. Series A is focused on refining the business model, expanding market reach, and securing the foundation for future growth. In contrast, Series B targets full-scale expansion, such as increasing operational capacity, growing the team, and entering new markets. Each round represents a vital step toward scaling and long-term success.
