FUNDRAISING GUIDE

Series B fundraising guide

Accelerate what is already working

Series B rounds fuel companies that have found their go-to-market engine and are ready to pour capital into growth. At this stage, investors expect operational maturity, a strong leadership team below founder level, and clear metrics demonstrating that more capital reliably generates more revenue. European Series B rounds typically involve both specialist growth VCs and crossover investors entering the European ecosystem.

Fundraising tips

Quantify your growth playbook precisely: show cost per acquired customer by channel, payback period, and projected scale of each channel.
Build relationships with US and global growth funds alongside European VCs — Series B is where international capital enters European rounds.
Prepare a board-ready investor update that demonstrates operational rigor; investors want to see how you run your business.
Negotiate from a position of optionality: if possible, have multiple term sheets in hand before accepting any.
Structure your use of proceeds around specific hires, market expansions, or product bets with measurable return expectations.

Common mistakes to avoid

!Assuming that Series A metrics will automatically justify a Series B — the bar moves significantly in terms of operational sophistication.
!Growing headcount ahead of revenue, creating a burn rate that makes the next round harder to justify.
!Neglecting international expansion planning — Series B investors often want to see a clear European or global land-and-expand strategy.
!Underinvesting in finance and legal infrastructure; due diligence at Series B is materially more intensive than at earlier stages.
!Accepting board seats from investors without clear governance agreements on reserved matters and information rights.
