Series B in the European Market
Series B in Europe in 2026 ranges €10M–€50M, with a median around €15M–€25M. Lead investors include growth-stage VCs (Insight, General Atlantic, Eurazeo Growth, Bain Capital Ventures Europe, Coatue Europe, Tiger), top-tier Series A funds doing follow-on or larger Series B, and increasingly European growth funds (Heartcore Growth, Lakestar Growth).
Expected metrics: B2B SaaS typically €3M–€10M ARR with 100%+ YoY growth and NRR above 110%; consumer companies need clear monetisation and unit economics with a path to profitability; deep tech and biotech need clinical or commercial proof points.
Valuations: €60M–€200M pre-money is the median range for software in 2026, with category leaders raising at €300M+. Dilution lands 15–25% to new investors.
Closing timeline: typically 4–8 weeks from term sheet to closing, with more intensive diligence than Series A (commercial due diligence by external consultants, deeper financial review, multiple customer reference calls).
Seniority Stacking Mechanics
By Series B you have at least three classes of preferred: Seed Preferred, Series A Preferred, and the new Series B Preferred. Each class has a liquidation preference; how they rank against each other determines exit payouts.
Two structures dominate. Pari passu (equal ranking): all preferred classes are paid in proportion to their preference amounts. €5M preference at Seed, €15M at Series A, €30M at Series B → in an exit, each class is paid pro rata to its preference. Senior (stacked): later rounds rank above earlier rounds. Series B is paid first up to €30M; then Series A up to €15M; then Seed up to €5M; then common splits whatever remains.
Stacked structures concentrate payouts at the top. In a €60M exit with €50M of total preferences, the senior structure pays €30M to Series B + €15M to Series A + €5M to Seed = €50M total preferences absorbed; common holders share €10M among 50%+ of the cap table. In a pari passu structure with the same preference totals, all preferred get 60% of their preference and common shares the same €10M residual — but founders may convert to common to share in residual if preferred coverage is incomplete.
European market default is pari passu seniority. Series B leads sometimes push for senior seniority; this is a major negotiation point. See the [liquidation preference guide](/captable/liquidation-preference) for the math.
Cumulative Dilution Across Three Rounds
A founder starting at 100% before any external capital typically lands at 35–45% after Seed, Series A and Series B — assuming clean rounds with standard dilution. Stack pre-seed convertibles, anti-dilution adjustments and pool top-ups and that figure can fall to 25–30%.
This is structural and unavoidable for venture-backed companies. The variable is whether the dilution is efficient (capital raised matches milestones achieved) or inefficient (multiple rounds at flat or down valuations because milestones missed).
Pay-to-Play and Down-Round Protection
Pay-to-play clauses sometimes appear at Series B as an investor protection: existing preferred shareholders who do not participate in their pro-rata share of a future down round lose their preferred status and convert to common. The clause is designed to force seed and Series A funds to follow on into difficult rounds — supportive of the company but punitive to investors who have run out of reserves.
In a healthy Series B environment, pay-to-play is non-controversial because no down round is anticipated. The clause matters at Series C or beyond if metrics turn. See [recapitalization](/captable/recapitalization) for how pay-to-play interacts with down-round mechanics.
Anti-dilution scope expands at Series B. Series B investors negotiate broad-based weighted average anti-dilution that triggers on any future down round below the Series B price. Anti-dilution adjustments at Series C — if any — reduce the Series B conversion price and increase Series B preferred shares, diluting common (founders and employees) further.
Pro-Rata, Syndicate Dynamics and Governance
Series A investors with pro-rata rights exercise them at Series B to maintain ownership. A Series A investor at 22% post-Series A who exercises pro-rata at a €20M Series B invests an additional €4.4M to stay at 22% post-Series B.
This creates fund pressure. Many European Series A funds reserve 1.5× to 2× the initial cheque for follow-on. A €6M initial Series A cheque has €9M–€12M of reserves. After full pro-rata at Series B and Series C, reserves are exhausted. Funds without remaining reserves either drop their position or push for "super pro-rata" terms in subsequent rounds.
Governance becomes denser. Series B typically adds another board seat or observer. Boards expand to 5 seats (2 founders, 2 investors, 1 independent) or 7 seats with multiple investors. Decision-making slows. Protective provisions accumulate — Seed has them, Series A has them, Series B has them, and each class can veto certain actions independently. A clean Series B shareholders agreement consolidates the protective provisions across classes; a sloppy one stacks them and creates unanimous-consent paralysis. See [protective provisions](/captable/protective-provisions) for the consolidation tactics.
