For most founders, Series A will be the first “priced” round whereby the Company’s valuation is explicitly determined before new investors purchase shares. Most Series A rounds are led by well-known institutional investors that have previously had significant investment experience.

It is commonly believed that the market for Series A financing has been particularly tough after the market downturn of 2022. To challenge this view, several industry observers have explained that the contraction is a “return to the normal” whereby venture activity has returned to the same levels as before the ZIRP eta. Historical data on venture activity corroborates this viewpoint.

Stage Expectations

At Series A, investors evaluate investment opportunities based on growth and traction metrics. Most investors expect a detailed data room that clearly lays out key trends in the financial, growth and traction performance of the Company. The specific nature of the metrics and the content for the data room varies significantly by sector and by business model.

Ultimately, Series A rounds are focused on a compelling forward-looking growth narrative. Historical growth matters to the extent that it can be used as a proxy to project future growth.

At the lower end. SaaS companies have successfully raised Series A rounds with only $0.5-1m in annualized run rate (with 100-150% year-over-year growth). On the upper end, companies have shown $3-3.5m in annualized revenue run rate (with 500%+ year-over-year growth). These benchmarks vary significantly based on business models, sectors and geography.

Stage Objectives

At Series A, companies are raising capital to double down on a validated market opportunity. At this stage, capital is typically deployed to achieve 3-5x revenue growth (over a 12-24 month time-frame).

For operations-heavy businesses, demonstrating the right level of progress on unit economics will be a key objective. For B2B SaaS companies, top-line growth will be a critical evaluation criteria. In most scenarios, founders will want to set measurable objectives for the round that will qualify the Company for the next stage.

Round Size & Valuations

Based on industry benchmarks and our market research, Series A rounds for B2B SaaS companies in the US range from $5-20m (with the median coalescing around $10m). The below chart from Carta provides an overview of median round sizes from 2020-23:

Valuations and round sizes at Series A have remained fairly consistent in recent years. We do, however, see significant fluctuations across sectors:

Optionality at Series A

At Series A, founders have a lot more optionality than they do at Pre-Seed, but a lot less than at Seed. This is because a fairly limited number of investment firms specialize at Series A. The below chart shows the total number of active investors in the US that specialize at Series A:

The above chart draws on US-based investors that are actively investing, that have made at least 10 lifetime investments, and that have made at least 25% or more of their total investments in the specific stage mentioned above (to qualify as a stage specialist).

Investor Types at Series A

Unlike other rounds, VC firms tend to play a much bigger role at Series A than they do at Pre-Seed or Seed. About 60% of all venture investments at Series A are from VC firms.

Intuitively, the above data makes sense given that round sizes are larger at Series A, requiring a deeper and more nuanced ability to navigate the risk-reward dynamics.

Investors to Target

At Series A, the biggest challenge is to find a lead investor that can then coalesce other investors into the round. Based on data shown above, the number of investors participating in Series A rounds tends to be much larger than those leading.

Founders, therefore, need to start their search with a focus on identifying the right lead investor. For founders, a common pitfall to avoid is the inclination to engage non-lead investors in a Series A process when the Company hasn’t yet secured a lead for the round.

Summary

Series A is different from prior rounds – there is generally less optionality, investors lean in heavily on traction and operating data, and finding a lead is particularly important given the round size. In navigating these dynamics, a strong focus on being super targeted on the “most likely” investors gives founders an important edge.
