What is Series A Funding?

Series A funding, (also known as Series A financing or Series A investment) is the first round of venture capital funding for a startup. It is a form of equity based financing and and is considered early stage funding.

Equity-based financing refers to a form of financing in which a company raises capital by issuing shares of ownership (stock) in the company to investors. The investors, in exchange for their investment, become shareholders of the company and are entitled to a portion of the profits and assets of the company proportional to their ownership.

This type of financing differs from debt financing, where a company borrows money and must repay the loan with interest. Equity-based financing is often used by startups and growing companies that do not yet have a proven track record and are unable to obtain debt financing.

Equity-based financing can come from a variety of sources, including angel investors, venture capital firms, and initial public offerings (IPOs).

The Series A funding round follows a startup company's seed round and precedes the Series B Funding round. "Series A" refers to the class of preferred stock sold. Here is a video that explains venture capital funding round cycle. The range of Series A funding a company get varies based on many factors, but below are some current averages.

Series A Funding Valuation

When investors look to value a company before a Series A, known a pre-money valuation, many factors are analyzed. Among them are company revenues, profit margin, growth rate, total addressable market, team, ability to execute, IP, etc. For example, here are some of the metrics analyzed for Saas Companies in determining valuations along with some current stats on SaaS valuations.


Series A Funding Requirements


Receiving a Series A round is an important milestone for startup companies. Aside from the funding being much larger than a seed round, companies need to demonstrate they have a minimum viable product (MVP) to acquire an A round - and not just a great idea or team. It is not easy for seed funded companies to graduate to a Series A funding round.

In fact, less than 10% of companies that raise a seed round are successful in then raising a Series A investment and 30% of startups fail because of lack of funding. A Series A investment provides venture capitalists, in exchange for capital, the first series of preferred stock after the common stock issued during the seed round. Generally speaking, a Series A financing provides up to a couple of years of runway for a startup to develop its products, team and begin to execute on its go-to-market strategy.

How to Get Series A Funding

A major factor in a startup be able to raise an A round or even a seed round is the startup ecosystem surrounding it. Startup ecosystems refer to the network of organizations, institutions, and individuals that support the development and growth of startups. This includes venture capital firms, angel investors, accelerators, incubators, government agencies, universities, research institutions, service providers, and other stakeholders.

The startup ecosystem provides a lot of the resource requirements, infrastructure, and support systems that startups need to succeed, such as access to funding, mentorship, training, and market opportunities. The interconnectivity and interdependence of these various elements are what make up the overall startup ecosystem, which can vary greatly from one location to another.

A thriving startup ecosystem is typically characterized by a supportive culture, a strong network of mentors and advisors, a readily available pool of talent, and a strong culture of entrepreneurship and innovation.

How to Get Series A Funding:


1. Join an Accelerator

Approximately one-third of startups that raise Series A funding go through an accelerator and the top 3 accelerators account for 10% of all Series A rounds. The #1 factor evaluated for acceptance into leading accelerators is your team.


2. Leverage Your Network

When fundraising, your network is critical. While joining a top-tier accelerator gives you the best statistical chance for success in ultimately getting a Series A funding, these groups only accept about 2% of applicants[5]. Startups that successfully raised a Series A without going this route often did so by networking early and often with influential investors, whether they are Angel Investors or VCs from leading venture capital firms.


3. Extend and Nurture Your Network

Continue to nurture and leverage angel and micro-VC connections before even thinking of pitching them. Take As many new meetings as You can. Building and nurturing genuine relationships before starting the Series A tour can dramatically improve your odds.



What is Series B Funding?

Series B Funding Details:

Series A vs. Series B. While a Series A funding round is to really get the team and product developed, a Series B Funding round is all about taking the business to the next level, past the development stage. Tomasz Tunguz, a well known Venture Capitalist at Redpoint, says a Series B funding is the most challenging round for a startup company, so be prepared before you present your pitch.

Typically before this funding series can occur, the company has to have shown some strong achievements after its Series A round. Series B is therefore to pour the gas on for growth with a larger investment round.

What is Series C Funding?

Series C Funding Details:

A Series C Funding Round generally occurs to to make the startup appealing for acquisition or to support a public offering. If you are wondering what series is usually the last, a company will most often end its external equity funding with Series C. This is the first of what are also called "later-stage" investments. This can continue into Series D funding, Series E funding, Series F funding, Series G funding, private equity funding rounds, etc. While there is a lot of capital ready, a lot of companies don't even make it to Series C. The reason for this is because before investors venture to participate in this round, Series C investors are looking for breakout companies that have already demonstrated significant traction. Thus, the deal size of Series C funding rounds has continued to increase.
