As businesses grow and evolve, they often require external funding to support their development and expansion. Navigating the different stages of funding can be challenging, especially for first-time entrepreneurs. Here is an overview of the main stages of funding for businesses and what they entail.

  1. Bootstrapping

Before seeking external funding, many entrepreneurs begin by bootstrapping their businesses. This involves using personal savings, income, or funds from friends and family to cover startup costs. Bootstrapping allows founders to maintain control over their businesses and avoid diluting their equity.

  1. Pre-seed Funding

Pre-seed funding typically comes after bootstrapping and represents the first external investment in a business. It is often raised from angel investors, accelerators, or incubators and provides capital for early-stage startups to validate their ideas, develop prototypes, and conduct market research.

  1. Seed Funding

Seed funding is the next stage of investment, aimed at helping startups refine their products or services, hire key team members, and further establish their market presence. Seed funding can come from angel investors, venture capital firms, and seed funds, with investments usually ranging from $100,000 to $2 million.

  1. Series A

Series A funding is designed to help businesses scale their operations, improve their products or services, and achieve profitability. At this stage, investors are typically venture capital firms that focus on early-stage companies. Investments can range from $2 million to $15 million, with investors looking for startups that demonstrate a solid business model, strong market potential, and a well-defined growth strategy.

  1. Series B

Series B funding supports businesses in expanding their reach, refining their products or services, and achieving financial stability. This stage typically involves larger investments from venture capital firms, with funding amounts often ranging from $10 million to $50 million. Investors in Series B rounds expect to see robust growth, a strong customer base, and a clear path to profitability.

  1. Series C and Beyond

Series C and subsequent funding rounds are aimed at mature companies that have demonstrated consistent growth and profitability. These rounds often involve larger investments from venture capital firms, private equity firms, and even public markets. Businesses seeking Series C or later-stage funding typically use the capital to expand into new markets, acquire other companies, or prepare for an initial public offering (IPO).

  1. Initial Public Offering (IPO)

An IPO marks the transition of a company from private to public ownership, allowing it to raise capital by issuing shares on a stock exchange. Going public can provide businesses with access to a wider pool of investors and increased capital, but it also comes with additional regulatory requirements and increased scrutiny.


Understanding the different stages of funding is crucial for businesses seeking to raise capital and grow their operations. By being aware of the requirements, expectations, and challenges associated with each funding stage, entrepreneurs can make informed decisions and better position their businesses for success.

Virtual data rooms such as Ruby Datum play an important role in funding exercises, as they provide a secure platform for sharing sensitive information with investors, streamlining the due diligence process, and fostering trust between all parties involved. Incorporating virtual data rooms into funding rounds can help businesses save time, reduce risks, and ultimately secure the financing they need to reach their full potential.
