Startups go through various funding rounds along with their growth stages. Funding rounds such as seed funding, series A, series B, series C, and beyond serves unique purposes to support startups' development in different stages. In a more advanced funding round like series B, it's typically harder to secure capital, as investors have much higher expectations compared to early funding rounds. It is important for startup founders to understand what it takes to enter series B funding. This includes how much is the amount of series B funding, the differences with other rounds, and how to prepare for this funding round.
What is Series B Funding?
The series B funding is the second stage of startup funding rounds. It typically follows on from the previous successful series A funding round and is used to further develop the business. What comes after series B funding is typically series C round, followed by subsequent late stage or mezzanine financing rounds before potentially reaching an exit phase.Series B funding can take place when the company has achieved certain milestones, like validated product-market, strong revenue growth, and actionable scaling plan that addresses investor benchmarks. This round can help startups to move past the earlier phases of establishing the business and enter the phase of increasing revenue and even turning a profit. Series B funding sources typically come from venture capital (VC) or private equity (PE) funds. The amount offered during series B round averages around $27 million, with the startup valuations reaching a median of $117 million at this stage of funding.Read More: Business Funding: Strategy to Accelerate Company GrowthWhat is the Difference Between Seed, Series A, Series B, and Series C Funding?
