Startups may necessitate more funds at various levels of growth so as to expand further. These rounds generally come after a startup has received seed funding which is the first round of financing that it gets. Through series A, B and C funding rounds companies get an opportunity for significant growth in different areas such as scaling up their operations.

What Is Series Funding?
Series funding refers to the successive rounds of financing that a startup undergoes to raise capital from investors. Successive steps in the investment of Series A, B, and C are crucial for startups and they depend on it for their development and accomplishment of particular goals.
These financing stages are called Series A, B, and C funding due to their alphabetical order. After initial seed funding, Series A is considered the first substantial round of institutional investment.
How Series A, B, and C Funding Rounds Work
When businesses first start out, they often need funds to help them grow. This is where series rounds of funding come in. Let us find out how series A, B and C funding rounds work:
1. Series A Funding Round
This is the first big round of money a startup gets after their initial seed funding. Venture capitalists (investors who fund new businesses) and angel investors (wealthy individuals who invest their own money) provide this Series A funding.
2. Series B Funding Round
Sometimes, a startup needs even more money after the Series A round. That’s when they go for a Series B funding round. Existing investors may put in more money, or new investors can join and invest as well. The investments in this round are usually larger than the Series A.
3. Series C Funding Round
Imagine a startup has successfully grown its business and shown it has great potential. At this point, they may seek Series C funding to really speed things up. With this extra money, they can expand into new markets, grow their operations even more, or even buy other companies (acquisitions) to become bigger and stronger. Only startups doing very well tend to reach the Series C stage.

What is Series A Funding?
Series A funding is a term used to describe the initial significant round of financial backing for a startup company following the seed funding stage. This phase often happens after a business has created a minimum viable product (MVP) and shown some early traction in the market.
How Does a Series A funding work?
When a startup company reaches the Series A funding stage, it seeks to attract investment from venture capitalists, angel investors, or other institutional sources of capital. These investors provide a significant sum of money in exchange for ownership shares in the company. The precise amount raised in a Series A funding round can span a broad spectrum, ranging from a few million dollars to tens of millions of dollars.
Ultimately, the total funding received hinges on several key factors, including the startup’s specific industry, its perceived potential for growth within the broader market, and its overarching strategic plans for scaling and expansion.
The funds obtained through a successful Series A financing round are typically allocated towards a diverse array of critical activities and operational imperatives. A sizable portion may be channelled into accelerating the development and enhancement of the company’s core product or service offerings.
Additionally, a significant investment is often made in bolstering the organization’s human capital by hiring experienced professionals to fill crucial roles across various departments and functional areas. Moreover, a substantial sum is typically earmarked for establishing robust marketing and sales channels, enabling the startup to effectively promote its solutions and create a strong customer base.
Finally, the remaining funds are commonly directed towards scaling up overall operations, facilitating the acquisition of necessary resources, infrastructure, and capabilities to support

What is Series B Funding?
When a start-up has grown significantly and needs more money to speed up expansion, Series B funding is the second large financing round. After a business has shown that it is profitable, has a good number of customers who regularly buy from them and after they have hit certain key performance indicators then this type of investment usually follows on from Series A. Therefore, this round comes into play once these other conditions are met.
How Does a Series B Funding Works?
Businesses need a lot of money to grow and expand their operations. This is where Series B funding comes in. During this funding round, startups look for more investors to provide them with the cash they need. These investors can be existing ones or new ones with additional skills and resources.
The amount of money raised during a Series B funding round can vary a lot. However, it is usually much more than what was raised during the previous Series A round. It can range from tens of millions of dollars to even hundreds of millions.
The money raised from Series B funding is typically used for several important activities. These include expanding the business into new markets and regions. Startups can also use this funding to increase their production capacity and capabilities.
Another key use of Series B funding is to enhance and improve the company’s products or services. The money can also be utilized for strategic acquisitions or partnerships with other companies. This can help the startup gain new expertise, technologies, or entry into different industries.
What Is Series C Funding?
Series C funding is commonly known as the third major round for startups and it is given to those which have grown significantly and will be able to make profit or exit successfully through initial public offering (IPO) or acquisition.
How Does a Series C Funding Works?
At a startup’s Series C funding round, it looks for money from a diverse group of investors. This includes late-stage venture capitalists who put money into companies further along their journey, as well as private equity firms and institutional investors like hedge funds or mutual funds.
The amount raised during a Series C round can be massive – often hundreds of millions or even billions of dollars. Companies obtaining Series C funding are usually well-established, with a proven business model and strong revenue streams.
Startups use the major influx of Series C capital for several key purposes. One common goal is international expansion, taking their products or services global by entering new markets abroad. The funds also enable aggressive marketing pushes to rapidly grow brand awareness, user acquisition, and sales.
Additionally, Series C financing frequently bankrolls strategic acquisitions, allowing the startup to buy other companies that complement their operations or bring new capabilities in-house. Finally, many startups use this late-stage funding to pave the way for an eventual IPO exit or positioning themselves as an attractive acquisition target for a larger corporation seeking to absorb their innovation and talent.

Bottom Line
Starting a business needs money to grow. Companies get money from investors through different rounds of funding. The amount of money and terms vary based on the company’s industry, potential market, and growth plan. But the main purpose of funding rounds is to give companies the cash to expand their operations and reach their long-term growth goals.
