Series A funding represents the most critical inflection point in a startup’s journey — the moment when a promising early-stage company must prove it can become a scalable business. With a median European Series A now sitting between €5 million and €10 million, the stakes are higher than ever, and the bar for what investors expect has risen sharply. This playbook covers everything founders need to know about raising a Series A round in today’s market.
Unlike seed rounds, where investors bet largely on the team and the vision, Series A funding demands evidence. Product-market fit must be demonstrated, not just claimed. Revenue metrics need to tell a clear growth story. And the founding team must show they can execute on a credible plan to scale. Understanding what Series A investors look for — and how to position your company for the raise — is the difference between closing a competitive round and spending months in fundraising limbo.
What Is Series A Funding?
Series A is typically the first institutional venture capital round with a priced equity structure. While seed rounds are often raised on SAFEs or convertible notes with light governance, Series A introduces formal term sheets, board seats, liquidation preferences, and detailed shareholder agreements. The “Series A” label refers to the class of preferred shares issued to investors — Series A Preferred Stock — which carries specific rights and protections.
In practical terms, a Series A round typically ranges from €3 million to €15 million in Europe, with the median hovering around €7 million. The round is led by one institutional VC fund (the “lead investor”), which sets the terms, conducts the deepest due diligence, and usually takes a board seat. Other investors — earlier seed investors, angels, or co-investing funds — may participate alongside the lead.
The capital raised at Series A funds the transition from early traction to scalable growth. Typical uses include expanding the engineering and product team, building a structured sales and marketing operation, entering new markets, and professionalising the company’s infrastructure.
When Is the Right Time to Raise a Series A?
Timing a Series A raise is as much art as science, but there are clear signals that indicate readiness. Raising too early — before the metrics justify the valuation — leads to painful down rounds or failed fundraises. Raising too late — after the company has run dangerously low on cash — weakens negotiating leverage.
The strongest signal is consistent revenue growth. For B2B SaaS companies, this typically means reaching €500,000 to €2 million in annual recurring revenue (ARR) with month-over-month growth rates of 15-20% or more. For marketplace or consumer businesses, the equivalent might be strong unit economics, high retention rates, and evidence of network effects beginning to compound.
Beyond revenue, investors look for product-market fit indicators: low churn, high NPS scores, organic word-of-mouth growth, and a sales cycle that is becoming more predictable. If customers are actively pulling the product rather than needing heavy sales effort to push it, that is a strong signal.
Runway is the practical constraint. Most advisers recommend beginning the Series A process when you have 9-12 months of cash remaining. The fundraising process itself typically takes 3-6 months from first meeting to wire transfer, and you want to negotiate from a position of strength rather than desperation.
What Series A Investors Look For
Series A investors are evaluating a fundamentally different question than seed investors. At seed, the question is “could this work?” At Series A, the question is “is this working, and can it scale?” The criteria reflect this shift.
Proven product-market fit. This is non-negotiable. Investors want to see that real customers are paying for the product, using it regularly, and deriving measurable value. Vanity metrics — downloads, page views, free signups — are insufficient. Revenue, retention, and expansion metrics matter.
A credible path to scale. Series A investors are not just funding the current state of the business; they are funding the next two to three years of growth. They want to see a clear go-to-market strategy, an understanding of customer acquisition costs (CAC) and lifetime value (LTV), and a roadmap for how the capital will be deployed to accelerate growth.
A strong founding team. At this stage, the team needs to demonstrate not just vision but execution capability. Have they shipped product on time? Have they closed enterprise deals? Can they recruit top talent? Investors also assess whether the team has the right composition for the next phase — a technical co-founder, a commercial lead, and increasingly a senior hire with scaling experience.
Market size and timing. The total addressable market (TAM) needs to be large enough to justify a venture-scale outcome. Investors are looking for markets worth at least €1 billion, with structural tailwinds — regulatory changes, technology shifts, or behavioural trends — that make now the right time to build in this space.
Key Metrics for a European Series A
While every company is different, the following benchmarks represent the median expectations for a competitive European Series A round in 2026:
B2B SaaS: €500K–€2M ARR, 15-20% month-over-month growth, net revenue retention above 110%, gross margins above 70%, CAC payback under 18 months.
Marketplace: €1M+ in gross merchandise value (GMV) per month, strong take rate, evidence of network effects, repeat purchase rates above 40%.
FinTech: Regulatory approvals secured or in progress, €1M+ in transaction volume, clear path to unit profitability, and ideally a banking or payments licence.
DeepTech / HealthTech: These sectors are somewhat different — investors may accept lower revenue if the technology is defensible (patents, regulatory moats). However, they expect clear milestones: successful pilots, letters of intent from enterprise customers, or regulatory progress.
The Series A Fundraising Process
A well-run Series A process follows a structured timeline. Rushing it leads to suboptimal terms; dragging it out drains management attention.
Months 1-2: Preparation. Build your investor target list (30-50 funds), prepare your data room, refine your pitch deck, and rehearse your narrative. The data room should include financial model, cap table, key contracts, team bios, product roadmap, and customer references. This preparation phase is critical — underprepared founders waste meetings and burn through their target list.
Month 3: Outreach and first meetings. Warm introductions convert at 5-10x the rate of cold emails. Leverage your seed investors, advisers, and network to get introductions to partners (not associates) at your target funds. Aim to have 15-20 first meetings compressed into 2-3 weeks to create competitive tension.
Month 4: Deep dives and due diligence. Interested funds will request follow-up meetings, customer references, and detailed financial data. The best outcome is having 2-3 funds moving through due diligence simultaneously — this creates leverage and ensures you are not dependent on a single investor’s timeline.
Month 5: Term sheet and close. Once a lead investor issues a term sheet, you have 1-2 weeks to negotiate terms and decide. After signing, the legal process (definitive agreements, shareholder agreements) takes another 4-6 weeks. Total time from first meeting to money in the bank: 3-5 months.
Understanding the Series A Term Sheet
The term sheet is the most consequential document in the fundraising process. While it is technically non-binding (except for exclusivity and confidentiality clauses), it sets the framework for the final legal agreements. Key terms to understand include:
Pre-money valuation. This determines how much of the company the new investors will own. A €20 million pre-money valuation with a €5 million raise means investors get 20% of the company (€5M / €25M post-money). European Series A valuations typically range from 10-30x ARR for high-growth SaaS, though this varies significantly by sector and market conditions.
Liquidation preference. The standard is 1x non-participating preferred — meaning investors get their money back first in an exit, then share in the remaining proceeds pro rata. Participating preferred (where investors get their money back AND share in the upside) is more aggressive and less founder-friendly.
Anti-dilution protection. Broad-based weighted average is the standard and most founder-friendly form. Full ratchet anti-dilution is aggressive and should be resisted — it can dramatically increase investor ownership in a down round.
Board composition. A typical post-Series A board has 3-5 seats: 1-2 founders, 1 lead investor, and 1-2 independent directors. Board composition affects governance and decision-making for the life of the company, so negotiate thoughtfully.
Employee option pool. Investors typically require a 10-15% unallocated option pool, created from the pre-money valuation (which effectively dilutes founders, not investors). Negotiate the pool size carefully based on your actual hiring plan.
Most Active Series A Investors in Europe
The European Series A landscape has deepened significantly, with both local and international funds competing for the best deals. Among the most active and respected Series A investors in Europe are Balderton Capital, Accel, Index Ventures, EQT Ventures, Northzone, Atomico, Creandum, and Lakestar. Sector-specialist funds have also emerged as powerful Series A leads — Speedinvest for fintech, Elaia for deeptech, Partech for cross-sector European deals, and Molten Ventures for enterprise software.
International funds with growing European presence include Bessemer Venture Partners, General Catalyst, and Lightspeed Venture Partners. Their entry has compressed the gap between US and European Series A terms, generally to the benefit of founders.
Common Mistakes in Series A Fundraising
The most frequent mistakes that derail Series A fundraises in Europe include raising too early before metrics justify the round, which leads to rejections that damage the company’s reputation with those investors permanently. Overspending the seed round on growth experiments without proving a repeatable acquisition channel leaves founders with impressive burn rates but underwhelming metrics.
Targeting the wrong investors wastes months of precious time. A deeptech startup pitching a pure SaaS fund, or a pre-revenue company approaching a Series A fund that requires €1M ARR minimum, is burning bridges unnecessarily. Research each fund’s thesis, stage focus, and portfolio before requesting a meeting.
Finally, neglecting the narrative is a surprisingly common error among technical founders. The data matters, but investors are also buying into a vision of the future. The best Series A pitches combine rigorous metrics with a compelling story about why this team, in this market, at this moment, will build something transformative.
