What Series A, B, C & D Funding Is & How It Works (2024)

Series A, B, C, & D funding are funding rounds that take place after an initial investment, typically known as the “seed funding stage.” Each round allows investors to partake in an investment in a high-potential startup or small business in exchange for a stake in equityEquity stake refers to the ownership percentage an investor has within a business. This is usually accommodated by a convertible note, which is the financial agreement between the investor and your business.. These rounds typically have various purposes, funding amounts, and valuations, all of which intend to promote the growth and expansion of the business being invested in.

Key takeaways

  • Each funding round can include various types of investors who will receive ownership positions in exchange for varying investment amounts.
  • Series rounds take place after preseed and seed money stages.
  • Not all funding rounds have to be utilized by a business and can be pursued until business needs and stabilization are met.
  • The further a business partakes in funding rounds, the more equity is given up and the larger the business scale becomes.
  • Investors can include venture capitalists, private equity firms, startup accelerators, hedge funds, and investment banks.

How Series A, B, C & D Funding Works

Funding Round

Investor Types

Purpose

Series A

Angel investors, venture capitalists, and startup accelerators

Stabilize and bring the business to the mass market

Series B

Venture capitalists and private equity firms

Expand product and delivery, explore new markets, and grow team

Series C

Venture capitalists, private equity firms, and hedge funds

Prepare for international expansion or initial public offering (IPO)

Series D

Venture capitalists, private equity firms, hedge funds, and investment banks

Promote expansion further or compensate for lack of capital in previous rounds

In raising venture capital for a business, Series A, B, C & D funding rounds provide opportunities for a business to achieve its goals by receiving both financial and experiential support from investors.

Each round comes with varying requirements, all with the intention of setting growth benchmarks. Each round also supports a different purpose—whether it be developing products, expanding into new markets, or bringing the company public.

In raising series A, B, C & D funding, not every round has to be utilized by a business. Most companies only make it to Series C, where—at that point—the company is maturing and has a strong reputation and foothold in the market.

It’s worth noting that factors, such as average funding amounts and business valuations fluctuate from year to year, depending on the market.

Series A

Generally from $2 to $20 million

Average of $10 million to $20 million

Pitch your business plan and growth projections

Series A is the first funding round after the initial seed stage investments and is usually provided by venture capitalist firms, angel investors, and startup accelerators. Primarily used for stabilization and expanding the business in the market, this stage supports businesses with a working product and a presence in the market.

Since most startups can be unstable in revenue at this stage, series A funding amounts provide funding to businesses that already have a valuable customer base and strong growth trajectory. The total funding amount received will vary depending on business needs and investor interest and is generally anywhere from $2 million to $20 million.

The valuation of a startup at this stage factors in the size of the business, product development, and market fit. Most businesses at this point have a valuation average of anywhere from $10 million to $20 million, but this value can vary greatly depending on the business.

To prepare for a series A funding round, write a business plan, which should be available to investors. This business plan should showcase the business background and structure, financial history, operations and product development, market need, and growth potential.

Series A example: A rapidly growing startup is seeking investments to help it keep up with its business operations and expand. Let’s say it has secured Series A funding via a venture capital firm. The funds are used to gain traction in the market and promote the business to a wider audience.

This round of funding helped stabilize and scale the business operations, provided for the onboarding of more team members, and accelerated product development for expansion into the market.

Series B Funding Round

Series B

Generally from $5 to $15 million

Average of $30 to $60 million

Show strong evidence of growth and strategy for continued profitability

Series B is the second funding round and serves to scale the business further and provide expansion of production and distribution into new markets. The primary objectives of this stage include the growth of operations, team structure, and customer outreach.

Funding is provided mainly by venture capitalists; however, private equity firms can invest as well. This stage is valuable since it offers support from investors, both financially and operationally, as they can provide business advice and guidance to help promote overall growth.

Series B funding amounts are to further promote growth by investing in the expansion results of the prior funding round and to divulge the business into new markets and seek a larger customer base.

The amount of funds raised will vary greatly depending on business needs and growth projections and can be driven by the amount of the previous round. Generally, funding amounts can range from $5 million to $15 million.

Obtaining series B funding is often considered the most difficult round to secure successfully as it usually requires proper scaling from prior funding rounds and a high business valuation, in which many startups may fall short.

This is calculated by factoring ownership percentages, along with pre- and post-investment valuations. Generally speaking, the valuation average of series B rounds runs anywhere from $30 to $60 million.

Evidence of growth is the main priority to secure series B funding, as investors will look to your market success and expansion plans. A strategy on continued profitability is essential to convince investors to further support growth efforts and to ensure ample returns on their investment.

Series B example: After continuing business growth and achieving stabilization successfully, the startup decides to promote new opportunities that better serve its customer base. To do so, the business seeks further financial support from investors to develop and market new products.

This funding round then allows for the pursuit of more customers, hiring of more staff to engineer the new products, and further market expansion.

Series C Funding Round

Series C

Generally from $25 million to $100 million

Average of $100 million to $120 million

Demonstrate strong profit metrics and team

Series C funding rounds are applicable to successful businesses that exceed expectations of prior funding rounds and are more prevalent in the market. This round is also suited for businesses contemplating plans for international expansion, acquisition, or IPO.

This round tends to have a more selective vetting process since investors receive further diluted equity stakes and try to mitigate risk in preparation for larger-scale expansion or acquisition. These investors are typically more established and can offer experience to help a business acclimate to expansion or acquisition plans.

Funding from a series C round will allow for further product development and capacity to heighten operations to fulfill expectations of moving into international markets, acquisition, or IPO. Funding amounts will vary greatly depending on expansion capabilities and generally fall within a range of anywhere from $25 million to $100 million.

Series C valuations will be tied to profit track records and focus on historical data rather than future company goals. Often, Series C is considered the final funding stage for most companies. Obtaining further investments requires a higher business valuation average, usually anywhere from $100 million to $120 million, although it can often be much higher.

To successfully prepare for international expansion or IPO, a business likely already has a strong foothold in the market and has its operations regimented for consistent profitability. You’ll need detailed proof of this since investors at this stage determine their investments based on the company’s historical metrics.

Series C example: The startup has grown its business further and has broadened its customer base enough to warrant requesting another funding round in pursuit of taking the company public. More investors now partake in funding the business and use their expertise to help facilitate the transition, which promotes business growth and preparation for expansion into international markets further.

Series D Funding Rounds

Series D

Varies greatly; anywhere from $100 million to $1 billion

Upward of $1 billion

Have a detailed action plan for further fund utilization

Series D and subsequent funding rounds are fairly uncommon. This is because this stage is usually used to prepare for IPO or acquisition, fund new opportunities, or cushion failed expectations from a previous round.

While ownership is diluted further, businesses can benefit from the expertise provided by these types of experienced investors to navigate the scaling of the business to a higher level. These investors look for companies with significant proven growth capabilities and include venture capitalists, private equity firms, and investment banks.

Because so few companies reach this stage, funding margins are vast and based on business needs. Whether it be a funding boost to launch a new product or to compensate for lack of capital in prior rounds, series D funding can run anywhere from $100 million to $1 billion.

If a company reaches a series D funding round, it is likely well established at this point and has a high valuation that reflects its profitability. Investors can require a valuation upwards of $1 billion, which is a rare target for startups to meet.

Like in previous rounds, a strong record of profitability and overall growth will be necessary to receive funding from investors, especially this far down the line. There will need to be detailed plans for funds utilization and thought as to how to bridge the gap between valuations, if necessary.

Series D example: The opportunity for acquisition has been presented to the startup. To ensure a smooth transition, the startup requests a final round of funding to maintain compliance and heighten the company’s valuation before exiting the business. The funds are used to tie any loose ends and eventually sell the business.

  • Businesses with long-term goals for expansion: Utilizing multiple funding rounds can promote a strong growth trajectory if a business has an interest in expanding into international markets in the future.
