Series Funding Explained: A Complete Guide to Series Funding A, B & C

Everything the successful startup has in common is money to grow it, and while some entrepreneurs fund startups with their savings, others need investors to take ideas to the next level, thus the series funding A, B, and C.

Every round of funding pushes a business forward in various ways, starting from the product to its spread across markets. But then, trying to determine what round you are going for and when is the best time to get it can be very complex. This guide breaks down Series A, B, and C funding into a very comprehensible and simple explanation that can guide smart decisions towards your startup's financial future.

What is Series Funding?

Series funding is the process of raising capital in stages to help startups reach specific milestones at each growth phase. Pre-seed and seed funding start early investments that focus on product development and market fit. Then, there are the series A, B, and C funding rounds that take the startup further into growth and become increasingly ambitious with each round.

Why does Series Funding matter to a startup?

Progressive Growth: The structured funding process allows startups to achieve specific growth milestones at each stage.

Investor Confidence: The progression of funding rounds depicts the confidence of the investors in the startup from early seed investors to late-stage capital providers.

Scalability: Funding at every stage ensures that startups have capital for scaling operations, improving on their product, and the customer base.

Each round is built upon the success of the previous stage, thereby ensuring that the startups have sufficient financial resources to meet their changing business needs and growth objectives.

The Series Funding Ladder

Here’s a clear overview of how startups progress through funding rounds:

Pre-Seed Funding: The earliest stage where founders, family, and friends invest to bring a startup idea to life.

Seed Funding: Angel investors and seed funds provide capital to develop a minimum viable product (MVP) and validate market potential.

Series A Funding: Early-stage venture capitalists (VCs) invest to refine the business model and scale initial operations.

Series B Funding: Growth-stage VCs step in to support market expansion, hire key talent, and scale infrastructure.

Series C Funding: Late-stage VCs fund major growth initiatives, such as market dominance, acquisitions, or preparing for an IPO.

Each stage represents a critical milestone, helping startups evolve from proof of concept to market leader, with funding aligned to the needs of their growth phase.

The Stages Before Series Funding: Pre-Seed and Seed Funding

Generally, before achieving series A funding, a startup undergoes two significant early phases: pre-seed and seed financing.

Pre-Seed Funding

Pre-seed funding is the starting point. Here, startups are usually developing an idea, prototyping, or researching the market. Funding mostly comes from the founders, family, friends, or early angel investors.

Range: $10,000-$500,000.

Real-Life Example:

Airbnb received $20,000 in pre-seed funding from Y Combinator to build its website and test the idea of renting air mattresses in their apartment. The seed funding helped turn the idea into a billion-dollar business.

Seed Capital Funding

Seed capital funding validates the idea, refines a product, and tests the business model through early customers after the presence of a prototype or minimum viable product. Seed investors usually include angel investors, seed funds, and startup accelerators.

Average Funding Amount: $100,000 to $2 million.

Equity Given Up: 10–25%.

Objective: Establish traction and get ready for larger funding rounds.

Real-Life Example:

Slack received $1.5 million in seed funding to refine its communication platform and prepare for Series A.

Series A Funding

What is Series A Funding?

Series A funding represents the first round of financing that most start-ups take after seed financing rounds. During this round, scaling is highly concentrated on scaling operations and products or services of customers of the business. In many instances, it includes venture capitalists as well as angel investors exchanging for equities in a firm upon investing financing.

At this stage, investors look for a product-market fit-the evidence that your product or service addresses a genuine need in the market. In Series A, one wants to get the company ready to scale significantly.

Why Is Series A Important for Startups?

Series A funding provides the necessary capital to convert an idea into a full-fledged business, thus marking an important step in a startup. After the seed round, startups need this funding to:

Develop products: Refine and enhance your offering based on market feedback.

Expand teams: Hire skilled employees across key departments like marketing, technology, and operations.

Boost marketing: Ramp up customer acquisition strategies to grow your user base and brand recognition.

Scale operations: Improve infrastructure, technology, and supply chains to handle increased demand.

Without Series A capital, many startups would struggle to move beyond their initial phase and grow into more established companies.

How to Raise Series A Funding?

Getting funding for Series A is strategic; here are a few tips toward increasing one's chances of raising that money:

Product/Market Fit: Investors need to feel confident that your product is solving a real problem.

Build a Strong Team: Investors prefer to back a skilled team with the ability to scale the company.

Make a Winning Pitch Deck: Present your value proposition, go-to-market potential, and financial projections clearly.

Leverage your network: Use industry connections and online platforms to connect with investors.

Present a Data-Driven Growth Plan: Outline how you’ll allocate the funds to achieve your next set of goals, such as hiring key personnel, improving technology, or expanding operations.

Strengthen Your Team: Show that you’ve assembled a capable leadership team that can execute the company’s vision at scale.

How Much Do You Raise in Series B?

The amount raised by startups in Series B rounds is generally between $10 million and $50 million. However, this number can be significantly different for various industries, locations, and companies.

Industry: The more growth-intensive sectors such as SaaS, fintech, or healthtech are the ones that tend to raise higher amounts.

Traction: Companies with high growth metrics, high customer retention, and predictable revenues are those that tend to raise more money.

Valuation: For most startups, the value lies in the range of $30 million to $60 million, with some exceptions reaching over $100 million.

Real-Life Example:

In 2008, Dropbox raised $6 million from Sequoia Capital. With this funding, they scaled up their infrastructure, staffed up, and garnered millions of new users who helped them become a market leader in cloud storage.

Series C Funding

What is Series C Funding?

Series C funding is the third major round of fundraising for startups, typically used to fuel rapid growth, market leadership, or an IPO or acquisition event. At this stage, companies have already gained a foothold in their markets with a proven business model that includes steady revenue and high customer retention.

Investments coming into Series C rounds consist of hedge funds, private equity firms, institutional investors, as well as sometimes late-stage venture capitalists. The essence of the investment is bringing big capital to help start ups scale globally, acquire competing businesses, or expand a startup into new markets.

Establish Market Leadership: This entails presenting evidence of market leadership through figures such as market share, revenue growth, and profitability or the potential of becoming profitable.

Highlight Scalability: Describe the manner in which this incremental capital will enable you to accelerate growth in a geometric manner through product development, market entry or acquisition.

Pitch to Late-Stage Investors: Hedge funds, private equity firms, and institutional investors only look at established businesses.

Valuation: The valuations at this stage are usually over $100 million and must be supported by your financials and future growth opportunities.

How Much Can You Raise in Series C?

Typically, the size of the round in Series C for a startup is between $50 million and $100 million or more. It depends on many factors, including:

Industry: Fintech, AI, biotech, and similar industries tend to attract bigger rounds.
