Business plan for Series A fundraise (€3M to €15M): metrics, structure, 2026 strategy

European Series A fundraises in 2024 range between €3 and €15 million, with €7 million median ticket per Pitchbook EMEA data. The Series A round typically occurs 18 to 36 months after Seed, after reaching product-market fit validation metrics with sustained growth. The most active European Tier 1 VC funds at Series A include: Index Ventures (London, San Francisco), Accel Partners (London, Munich), Atomico (London, Berlin, Stockholm), Balderton Capital (London), Partech (Paris, Berlin, Dakar), Eurazeo Growth (Paris), HV Capital (Berlin), Northzone (Stockholm, London, Berlin), Felix Capital (London, Paris), 360 Capital Partners (Paris, Milan, Munich).

Standard Series A ticket breaks down in 3 tranches: Small Series A (€3-5M) for B2C startups or vertical-specific markets, Classical Series A (€5-10M) for SaaS B2B with ARR €1-3M, Large Series A (€10-15M) for fintech, marketplaces, and deeptech with strong market validation. Beyond €15M, you enter the Series B perimeter or « extended » Series A. For a €8M Series A on €32M pre-money valuation, post-money valuation reaches €40M — i.e. 20% dilution for existing partners.

Three « champion » European funds emerge per segment. For SaaS B2B: Accel, Index, Atomico, Partech, Balderton. For fintech: Accel, Lakestar, Balderton, Mosaic Ventures. For deeptech and industrial: Eurazeo, Atomico, Northzone, Earlybird. For marketplace and consumer: Felix Capital, Index Ventures, Atomico, Balderton. For climatetech: Atomico, Lowercarbon Capital (US-based active in EU), Northzone, Eurazeo. This sector specialization is more pronounced than at Seed — choosing funds whose investment thesis precisely aligns with the project is critical.

For a Series A SaaS B2B startup, 2024 benchmark metrics are: ARR (Annual Recurring Revenue) minimum €1 million, 12-20% MoM growth (3-month moving average), gross monthly churn < 2%, NDR (Net Dollar Retention) > 110%, CAC payback < 18 months, LTV:CAC ratio > 3:1. Tier 1 VC funds generally target SaaS startups with ARR ≥ €2M and 100% YoY growth for their Series A — below, Series A is harder and valuation less favorable.

For an e-commerce or consumer Series A startup, metrics vary: GMV (Gross Merchandise Value) €5-15 million annualized, 80-150% YoY growth, gross margin > 30%, CAC payback < 12 months, 12-month cohort retention > 40%. For a marketplace: GMV €10M+ annualized, take rate 8-15%, liquidity growth (supply/demand matching), positive unit economics on mature transactions.

For a deeptech or hardware Series A startup, requirements shift: validated technical milestones (industrial POC, filed patents), first significant commercial contracts (€1-5M LOI or signed contracts), strategic partnerships with sector actors (Total, Saint-Gobain, Bouygues for construction, EDF for energy, Airbus for aerospace). Deeptech Series A ticket is generally higher (€8-15M) as capital needs are structurally larger (R&D, equipment, certifications).

Beyond product metrics, VC funds evaluate three team and governance dimensions. First: complete C-level team. Minimum CEO + CTO + CRO/COO, with backgrounds demonstrating scale execution capacity (ex-Google, ex-Spotify, ex-scaled startup founders). Second: structured board. Typical post-Series A composition: 5 people (CEO + 1-2 co-founders + 1-2 VCs + 1-2 independents). Third: sophisticated shareholders' agreement. Drag-along, tag-along, anti-dilution, preemption rights, detailed governance clauses.

• SaaS B2B: ARR €1-3M, MoM growth 12-20%, NDR > 110%, LTV:CAC > 3:1
• E-commerce: GMV €5-15M, gross margin > 30%, cohort retention > 40%
• Marketplace: GMV €10M+, take rate 8-15%, liquidity growth
• Deeptech: technical milestones + first contracts €1-5M
• Team: complete C-level (CEO + CTO + CRO/COO)
• Post-A board: 5 people (founders + VCs + independents)

The Series A business plan typically counts 40 to 60 pages, structured in 10 sections (vs 8 at Seed). Section 1 — Executive summary (2-3 pages) condensing the thesis. Section 2 — Market and competition (5-7 pages) with sourced TAM/SAM/SOM (Frost & Sullivan, IDC, Gartner studies), detailed competitive benchmark (10-20 competitors), differentiating positioning. Section 3 — Product and roadmap (4-5 pages) with 24-36 month roadmap and long-term technology strategy.

Section 4 — Business model and unit economics (6-8 pages) — the critical section at Series A. Revenue detail, pricing strategy, unit economics by cohort, sensitivity analysis (what happens if CAC doubles, churn doubles, etc.). Cohort graphs by acquisition month are expected. Section 5 — Metrics and KPIs (4-5 pages) with detailed dashboard (monthly ARR evolution, MRR by client segment, churn, NDR, blended CAC and by channel, payback period).

Section 6 — Commercial and marketing strategy (4-5 pages) with detailed acquisition funnel, channel mix (inbound, outbound, partnerships, content marketing), blended CAC and by channel with optimization trajectory. Section 7 — Team and recruitment plan (3-4 pages) with complete C-level, advisors, 24-month recruitment plan (typically 30-50 hires over the period). Section 8 — Expansion strategy (3-4 pages) with geographic roadmap (typically 2-3 new EU countries over 24 months) or multi-segments (additional verticals).

Section 9 — Financial and projections (8-10 pages) — the longest. Monthly P&L 36 months, detailed cash flow plan, projected balance sheet, explicit hypotheses for each line, sensitivity analysis. For a €8M Series A, typical runway is 24 to 36 months — demonstrate the funds cover until Series B (generally with €10M+ ARR for SaaS). Section 10 — Use of funds and next round (3-4 pages) with detailed €8M breakdown (typically 55-65% salaries, 20-25% marketing/sales, 5-10% product/R&D, 5-10% operational, 5% buffer), 24-month KPI targets for Series B.

Series A due diligence combines four audit dimensions. First, commercial audit: interviews with 5-10 reference customers, main contract analysis, pipeline verification, NPS and satisfaction validation. Second, financial audit: complete audit of last 24 months (by an accounting firm mandated by VC), accounting and fiscal validation, hidden risk identification. Third, technology and IP audit: code review, architecture, scalability, cybersecurity audit, patent and copyright verification. Fourth, legal and social audit: statute verification, key contracts, intellectual property, employment contracts, potential litigation. This due diligence takes 6 to 12 weeks at Series A (vs 2-4 weeks at Seed).

Series A term sheet includes 20 to 30 clauses (vs 12-15 at Seed). Beyond standard Seed clauses, at Series A: (1) preferred shares with 1x non-participating liquidation preference (rarely 2x or participating in EU vs USA), (2) full ratchet anti-dilution or weighted average broad-based, (3) board seats (1 lead + 1 co-investor + 1 independent appointed by majority agreement), (4) drag-along with typical 51-66% capital threshold, (5) extended veto rights (transfer, merger, capital increase, C-level recruitment, annual budget), (6) monthly information rights (KPIs, P&L, cash) and quarterly (complete board pack), (7) ROFR (Right of First Refusal) on share transfer by founders, (8) accelerated founder vesting over 4 years if involuntary departure.
