What Is Series A?

A Series A is typically the first significant institutional venture capital funding round, following seed or angel investment. It usually involves raising £3M-£15M at a pre-money valuation of £10M-£50M, and represents a company's transition from proving product-market fit to scaling the business model.

In Depth

Series A is the gateway between the experimental seed stage and the scaling growth stage. It is often the most transformative funding event in a startup's life, providing the capital to build out the team, invest in go-to-market, and grow revenue significantly.

Typical UK Series A benchmarks include: ARR of £1M-£3M, strong month-over-month revenue growth (8-15%), proven unit economics (LTV:CAC above 3:1), low churn (below 2% monthly), a clear ideal customer profile, and a repeatable sales process.

The Series A process typically takes 3-6 months and involves: preparing a comprehensive data room, crafting the investor pitch, running a structured fundraising process, negotiating term sheets, completing due diligence, and closing the round.

FP&A teams are central to Series A preparation. The financial model must demonstrate: historical performance with clear trends, a bottoms-up revenue forecast tied to operational drivers, a detailed use of proceeds showing how the capital will be deployed, the path to key milestones (typically Series B metrics or profitability), and scenario analysis showing sensitivity to key assumptions.

Series A investors (VCs) typically invest from dedicated funds, take board seats, negotiate significant protective provisions, and expect 10x+ returns. Understanding investor economics helps FP&A teams frame the investment case effectively.

Real-World Example

A UK healthtech company reaches £1.8M ARR growing 12% month-over-month, with 1.1% monthly churn and 4.5:1 LTV:CAC. The FP&A team builds a Series A model showing £5M raise at £18M pre-money. Use of proceeds: hire 20 people (product + sales), invest in enterprise features, and achieve £7M ARR within 18 months. The model includes three scenarios: base (£7M ARR), upside (£9M ARR with faster enterprise sales), and downside (£5M ARR if market adoption slows).
