Most Active Series A Investors in Europe

What is a Series A round?

A Series A is a startup's first significant institutional priced equity round, typically raised after a company has moved beyond early experimentation and can demonstrate repeatable, measurable traction. It sits between the seed stage — where capital is used to validate a hypothesis — and Series B, where the focus shifts to scaling a proven model at speed.

At the seed stage, founders are often working with angels, accelerators, or small seed funds to build a product and find initial customers. By contrast, a Series A is led by institutional venture capital firms that take a board seat and expect a clear path to a large market. Series B investors, meanwhile, want to see efficient growth at scale — something a Series A company is still working toward building.

What distinguishes Series A from adjacent stages is the combination of evidence and ambition required. Investors are not simply betting on a founder's vision; they need to see early product-market fit signals, a functional team capable of execution, and a credible thesis for how the business reaches significant revenue within a defined horizon. The diligence process is substantially more rigorous than at seed, involving detailed commercial, financial, and sometimes technical review.

In Europe, Series A rounds have historically been smaller than their US counterparts, though the gap has narrowed meaningfully over the past several years as more US and global funds have entered European markets. European Series A rounds are now increasingly competitive, with term sheets from multiple investors not uncommon for strong companies. The round typically results in a formal shareholders' agreement, preferred share structure, and defined governance rights for the lead investor.

What are the goals of Series A funding?

Series A capital is primarily deployed to transform early traction into a scalable, repeatable business model. Unlike seed funding — which is often used to build a product and find the first customers — Series A capital is meant to answer the question of whether the company can grow efficiently and predictably.

The most common uses of Series A capital include building out the go-to-market function, which typically means hiring experienced sales, marketing, and customer success professionals who can operationalise what the founders have been doing manually. For B2B companies, this often means constructing a structured sales motion with clear conversion metrics. For consumer companies, it might mean investing in paid acquisition channels or content infrastructure.

Product and engineering headcount also grows significantly at Series A. Companies use this capital to move from a minimum viable product to a more robust platform, improve reliability and security, and begin building the features that enterprise or growth-stage customers require. In regulated industries such as fintech or healthtech, Series A capital is often partly consumed by compliance, licensing, and regulatory infrastructure.

Market expansion is another common goal. A startup may have proven its model in one geography or customer segment and use Series A funds to enter adjacent markets, whether that means expanding from one European country to several others or moving upmarket from SME to mid-market customers.

The milestone a Series A is meant to fund is typically the evidence needed to raise a Series B: consistent month-on-month revenue growth, improving unit economics, a demonstrable sales playbook, and early signs of market leadership in a defined segment. Investors expect to see Series B-ready metrics within roughly eighteen to thirty months of closing.

Is my startup ready to raise a Series A round?

Determining Series A readiness is less about hitting a single threshold and more about demonstrating coherence across several dimensions simultaneously. Investors are looking for evidence that early success was not accidental and that a larger capital injection will accelerate rather than simply sustain the business.

On the revenue side, the most commonly cited benchmark for European B2B SaaS companies is approximately one to two million euros in annual recurring revenue, though this varies significantly by sector. More important than the absolute number is the growth rate and consistency — investors want to see month-on-month or quarter-on-quarter compounding rather than lumpy, one-off deals. Net revenue retention above one hundred percent is a particularly strong signal, as it implies the product delivers enough value that customers expand their usage over time.

Product-market fit signals go beyond revenue. Low churn, unprompted referrals, and customers who integrate the product deeply into their workflows all indicate that the problem being solved is real and urgent. Founders should be able to point to a cohort of customers who would be genuinely disrupted if the product disappeared.

The team signal is critical at Series A. Institutional investors are assessing whether the founding team can recruit and manage the twenty to fifty people who will join over the next eighteen months. Prior experience building teams, domain expertise, and complementary skills among co-founders all matter. Gaps in the leadership team — particularly in commercial roles — can slow or block a raise.

Market signals also matter. Investors want to understand whether the addressable market is large enough to support a venture-scale outcome and whether the company is positioned to capture a meaningful share. A credible narrative around market timing and competitive differentiation is essential.

What is the typical size of a Series A round?

In Europe, Series A rounds have grown substantially in size over the past decade and particularly since 2019. Rounds in the range of five to fifteen million euros were historically common, but the current market has shifted the typical range upward. Today, many European Series A rounds fall between eight and twenty million euros, with rounds at the higher end or beyond becoming more frequent for companies with strong traction in large markets.

Sector plays a significant role in determining round size. Deep tech, biotech, and hardware-intensive businesses often raise at the upper end or above typical ranges because the capital requirements for R&D, regulatory approval, and physical infrastructure are substantially higher than for software. A Series A biotech company may raise thirty million euros or more, while a B2B SaaS company serving a niche vertical might raise eight to twelve million euros and deploy it efficiently over two years.

Geography also influences round size within Europe. London-based startups tend to raise at the higher end of the European range, partly because of the concentration of global and US funds operating there and partly because operating costs are higher. DACH and Nordic companies often raise slightly smaller rounds by global standards but have historically been capital-efficient and financially disciplined. Southern and Eastern European companies frequently raise smaller Series A rounds, though this is changing as regional ecosystems mature and more international capital flows into markets like Warsaw, Lisbon, and Barcelona.

Compared to seed rounds, which typically range from one to three million euros in Europe, Series A rounds represent a step-change in check size and ambition. Compared to Series B, which commonly ranges from thirty to eighty million euros in Europe, Series A rounds are still in a phase of proving rather than scaling the model.

Different types of Series A investors

How to create a fundraising strategy for a Series A round

A well-run Series A process is deliberate, time-bounded, and treats fundraising as a competitive dynamic rather than a sequential set of conversations. Founders who approach it informally or reactively typically experience longer timelines, weaker terms, and unnecessary distraction from the business.

Preparation should begin three to six months before formally launching a process. This means getting key metrics into a clearly communicable form, identifying and warming relationships with target investors, and ensuring the business is performing well enough to withstand detailed diligence. A cold outreach to a top-tier VC the week before you need money is almost never effective at Series A.

Sequencing matters significantly. Founders should identify a shortlist of fifteen to twenty-five investors, tiered by conviction and relevance. It is generally advisable to run initial conversations with investors in the second or third tier before approaching top targets, both to refine the pitch and to gather market intelligence on how the opportunity is perceived. Once formal meetings begin with priority investors, founders should compress the timeline — ideally running all first meetings within a two to three-week window to create natural competitive tension.

Positioning should be specific and credible. Generic pitches about large markets and strong teams do not differentiate at Series A. Investors respond to a precise articulation of what the company has proven, what is still uncertain, and why this particular moment and this particular team are the right combination to capture the opportunity. Anticipating and answering the obvious pushbacks proactively — on competition, market size, or business model — demonstrates analytical honesty and builds trust.

Founders should also think carefully about the lead investor profile they want: a fund that has relevant portfolio companies, a partner with domain expertise, and a governance style that matches the company's needs at this stage.

What terms and dilution should I expect at Series A?

Series A rounds in Europe are almost always structured as priced equity rounds rather than convertible instruments such as SAFEs or convertible notes, which are more common at seed stage. A priced round means the company is formally valued at a specific pre-money valuation, and new shares are issued at a defined price. This triggers a full suite of investor rights, typically set out in a subscription agreement, shareholders' agreement, and articles of association.

The key economic terms at Series A include the pre-money valuation, which determines the price per share and the resulting ownership stake for new investors; liquidation preferences, which give preferred shareholders priority in exit proceeds, most commonly on a one-times non-participating basis in Europe; anti-dilution provisions, which protect investors if a future round is raised at a lower valuation; and pro-rata rights, which allow investors to maintain their ownership percentage in future rounds.

Founders typically experience dilution of fifteen to twenty-five percent at Series A, depending on the round size relative to the company's valuation. In competitive processes with strong traction, dilution can sit at the lower end of this range. In situations where a company is raising urgently or has fewer competing term sheets, investors may push for valuations that result in higher dilution.

Board composition changes meaningfully at Series A. The lead investor almost always receives a board seat, and it is common for the board to expand to five members: two founders, one lead investor, and two independent directors to be appointed. Founders should think carefully about who fills independent seats, as these individuals shape governance culture over time.

Unlike seed rounds, Series A terms are negotiated in detail and typically take four to eight weeks from term sheet to close, involving legal review on both sides.

Common mistakes founders make raising at Series A

One of the most frequent mistakes founders make at Series A is starting the process too early, before the business has developed sufficient evidence of product-market fit. Raising before the metrics justify a Series A rarely results in a successful outcome — it more often results in a long, demoralising process that ends without a term sheet and has damaged relationships with investors who might otherwise have been natural partners six months later.

The opposite mistake — waiting too long — also occurs. Companies that have strong traction but delay fundraising because they want to improve metrics further sometimes find themselves running out of runway in an adverse market environment. A healthy Series A process requires at least six to nine months of runway at the point of launching.

Founders also frequently underestimate the time and focus required. A Series A process typically consumes thirty to fifty percent of a founder's capacity for two to four months. Companies that do not plan for this operational disruption sometimes see performance dip during the raise, which creates a compounding problem as investors seeing deteriorating metrics lose confidence.

Pitch and narrative errors are common. Many founders present their business as a collection of features and metrics rather than a coherent story about why their market is about to change and why they are uniquely positioned to lead that change. Investors at Series A are making a judgment about the next five to seven years, not just the next quarter.

Negotiation mistakes are also prevalent. Founders sometimes accept the first term sheet out of relief rather than running a competitive process. Even if only one fund is genuinely interested, founders should understand all the terms — not just valuation — before signing. Governance terms, liquidation preferences, and information rights can matter as much as the headline price.

How does Series A funding differ across Europe?

The European Series A landscape is not a single market — it is a collection of overlapping ecosystems with meaningfully different dynamics in terms of round size, investor availability, founder expectations, and fundraising culture.

The United Kingdom, and London in particular, operates closest to US norms. Round sizes are generally larger, often in the twelve to twenty-five million euro range for competitive deals, and founders have access to a broader set of international investors including US funds with local offices. The process is typically faster and more competitive, with term sheets sometimes arriving within weeks of initial meetings. London also has a more established ecosystem of experienced founders who have been through the process before and can provide peer guidance.

The DACH region — Germany, Austria, and Switzerland — has produced a strong cohort of B2B SaaS, fintech, and industrial tech companies. Investors in this market tend to be methodical and diligence-heavy, which means processes often take longer. Round sizes are broadly in the European average range. Berlin leads the ecosystem, though Munich and Zurich have developed meaningful clusters of both founders and capital.

The Nordic countries — Sweden, Denmark, Finland, and Norway — have a disproportionately strong track record relative to their population size. Founders in this region tend to be capital-efficient and financially literate, and the ecosystem benefits from strong local funds as well as significant inbound interest from US and global investors. Rounds are competitive, and Stockholm in particular has become a European reference market for B2B software.

Southern Europe, including Spain, Portugal, and Italy, has seen substantial growth in Series A activity, particularly in Barcelona, Lisbon, and Milan. Round sizes remain below the European average but are growing. Eastern Europe — Poland, Romania, and the Baltic states — is an earlier-stage ecosystem overall, with a growing number of seed-stage companies approaching Series A readiness and increasing interest from pan-European funds seeking opportunities at more attractive valuations.
