Most Active Series C Investors in Europe

What is a Series C round?

A Series C round is a later-stage equity financing event that typically occurs after a startup has demonstrated repeatable, scalable growth across its core markets. It sits between Series B — where the focus is on proving the business model at scale — and pre-IPO or growth equity stages, where the company is preparing for a public offering or a significant liquidity event. By Series C, the company is no longer an early-stage bet; it is an established business with meaningful revenue, a functioning go-to-market engine, and a defensible market position.

What distinguishes Series C from Series B is the shift in investor logic. Series B investors are still underwriting growth potential and model validation. Series C investors are primarily underwriting market leadership, competitive moats, and the path to exit — whether IPO, secondary sale, or strategic acquisition. The diligence process becomes correspondingly more rigorous, involving detailed unit economics analysis, cohort retention data, competitive benchmarking, and management team depth assessments.

In the European context, Series C also frequently involves the entry of transatlantic capital. US-based growth funds and crossover investors regularly participate in European Series C rounds, particularly for companies operating in sectors with global addressable markets such as fintech, enterprise software, and climate technology. This introduces dynamics that earlier rounds rarely encounter: dual-track term sheets, parallel US and European investor processes, and pressure to demonstrate readiness for international expansion. Series C in Europe typically marks the point at which a company transitions from being a regional leader to positioning itself as a credible global contender.

What are the goals of Series C funding?

Series C capital is deployed with a different strategic logic than earlier rounds. Whereas Series A and B funding is primarily used to find and then scale a repeatable model, Series C capital is used to press advantage once that model is proven. The central use cases fall into several distinct categories.

International expansion is the most common priority. European startups at Series C frequently use the capital to enter the US market or to deepen penetration across multiple European geographies simultaneously. This involves hiring local sales and marketing leadership, building regulatory and compliance infrastructure, and adapting the product for new markets — all of which are capital-intensive.

M&A and consolidation is a second major use. Series C companies often acquire smaller competitors or complementary technology businesses to accelerate growth, eliminate competition, or broaden their product suite. This is especially prevalent in fragmented sectors such as HR tech, legal tech, and vertical SaaS.

Product platform expansion is a third driver. With the core product validated, Series C founders invest in building adjacent features, launching new product lines, or moving up or down the value chain to increase average contract value and reduce churn.

Talent and organisational infrastructure also absorb significant capital at this stage. Series C companies are building executive teams capable of operating at scale — CFOs, Chief Revenue Officers, and heads of engineering who can manage large organisations — and investing in systems, processes, and compliance structures that support rapid headcount growth.

Finally, some Series C rounds provide partial liquidity to early investors and employees through secondary transactions structured alongside the primary capital raise, though this varies considerably by company and investor.

Is my startup ready to raise a Series C round?

Investors evaluating a Series C opportunity apply a substantially higher bar than at earlier stages, and founders should assess their own readiness against the signals that growth-stage investors actually use.

On revenue and growth, a Series C candidate in Europe typically has annual recurring revenue or annualised revenue in the range of €20 million to €100 million or beyond, depending on the sector. Growth rates remain a key variable — investors expect to see year-on-year growth that is still meaningfully above the rule of 40 benchmark, with improving or at least stable net revenue retention. Slowing growth without a clear re-acceleration story is a significant deterrent.

Unit economics must be clearly positive or on an unambiguous trajectory toward profitability. Gross margins, customer acquisition cost payback periods, and lifetime value to CAC ratios should be well understood internally and presentable in a rigorous format. Investors at this stage will model these numbers independently and expect consistency with management's narrative.

Market position signals matter considerably. Series C investors want to back the clear category leader or a company with a strong second-place position in a large and growing market. Evidence of competitive displacement — taking customers from incumbents — is a strong positive signal.

Team depth is scrutinised more than at earlier stages. Investors assess whether the leadership bench beyond the founding team can support the operational demands of a much larger business. Gaps in the executive team are a common reason for investors to pass or defer.

Finally, the ability to articulate a credible path to exit — IPO readiness, strategic acquirer interest, or secondary market liquidity — is increasingly expected in the Series C narrative.

What is the typical size of a Series C round?

Series C rounds in Europe typically range from €40 million to €150 million, though this range is broad by design. Sector, geography, business model, and the specific ambitions of the company all influence where within that range a given round falls.

Enterprise software and fintech companies — which tend to have high gross margins and large addressable markets — frequently raise at the upper end of the range or above it. Climate technology and deep tech companies, where capital requirements for hardware, infrastructure, or regulatory processes are high, may also raise larger rounds. Consumer-facing businesses with thinner margins tend to raise more modestly unless they are demonstrating exceptional scale.

Geography shapes round size meaningfully. UK-based startups, particularly those in London, consistently raise the largest Series C rounds in Europe, benefiting from proximity to deep pools of growth capital and established relationships with US investors. DACH and Nordic companies have increasingly commanded competitive round sizes as institutional infrastructure in those markets has matured. Southern European and Eastern European startups at Series C tend to raise somewhat smaller rounds on average, though this gap has narrowed as pan-European and US investors have become more geographically agnostic in their sourcing.

Compared to Series B, Series C rounds are typically two to four times larger in absolute terms, reflecting both the expanded capital needs of a more mature business and the higher valuations at which the rounds are priced. Compared to growth equity or pre-IPO rounds, Series C remains a venture-stage transaction — investors still expect venture-scale returns and price accordingly. The distinction between a large Series C and a growth equity round can sometimes blur, particularly when growth funds and late-stage venture funds are competing for the same allocation.

Different types of Series C investors

How to create a fundraising strategy for a Series C round

Running a Series C process is materially different from earlier rounds, and founders who treat it as a scaled-up Series B process typically encounter avoidable friction. The preparation phase should begin six to nine months before the anticipated close, with three months dedicated to getting the data room, financial model, and investor narrative into institutional-grade shape.

Sequencing matters enormously. Founders should identify the ten to fifteen most relevant lead investors globally — not just in Europe — and tier them by strategic fit, likely check size, and decision-making speed. The goal of the first investor conversations is not to close commitments but to gather signal on how the market perceives the opportunity and to refine the narrative before the formal process launches. Running a tight, time-bounded formal process — typically six to ten weeks from first formal meeting to term sheet — creates the competitive dynamics that are essential for preserving leverage on valuation and terms.

Positioning should be anchored to market leadership rather than growth metrics alone. By Series C, investors are evaluating whether this company will be the dominant player in its category. The pitch should articulate a clear theory of how the capital will be used to create durable competitive advantage, not simply to grow faster.

Existing investors should be managed carefully. Their decision to participate or not will be read by incoming investors as a signal, so founders should have direct conversations with their existing boards about re-investment intentions before the external process begins.

Legal and governance preparation is also critical. Series C processes involve detailed due diligence on cap table cleanliness, option pool structure, existing investor rights, and any pending litigation or regulatory exposure. Addressing these issues proactively prevents late-stage process delays.

What terms and dilution should I expect at Series C?

Series C rounds in Europe are structured almost exclusively as priced equity rounds — convertible notes and SAFEs, which are common at pre-seed and seed, are not appropriate instruments at this stage given the maturity of the company and the size of the capital involved. The round is structured as a preferred equity issuance, typically with participating or non-participating liquidation preferences, anti-dilution provisions, and board representation rights negotiated as part of the term sheet.

Liquidation preference at Series C is most commonly set at 1x non-participating preferred, meaning investors receive their capital back before common shareholders in a downside scenario but do not double-dip by also participating in upside distributions. In competitive rounds with multiple investors competing to lead, founders are sometimes able to negotiate away participation rights entirely. In more difficult market conditions, investors may push for 1x or even 1.5x participating preferred, which has a more significant impact on founder and employee economics in acquisition scenarios.

Anti-dilution provisions at Series C are typically full-ratchet or, more commonly, broad-based weighted average, with the latter being more founder-friendly and market standard in well-structured European rounds.

Founder dilution at Series C typically ranges from 15 percent to 25 percent of the post-money equity, though this varies based on round size, pre-money valuation, and whether an option pool refresh is included. Founders should model the cumulative dilution across all rounds at this point — by Series C, founding teams frequently retain between 20 percent and 40 percent of the equity on a fully diluted basis, depending on how much they have raised in total and at what valuations. Board composition changes are also negotiated at Series C, with incoming lead investors typically receiving one board seat.

Common mistakes founders make raising at Series C

The most consequential mistakes at Series C tend to be strategic rather than tactical, and they often originate in misaligned assumptions about what growth-stage investors are actually buying.

The first common mistake is launching the process before the metrics are unambiguously compelling. Series C investors see hundreds of opportunities and can afford to wait for the clearest market leaders. Founders who go to market with ambiguous growth trajectories, unclear unit economics, or a recent quarter of underperformance frequently find that investor enthusiasm is lower than expected, forcing either a down round, a longer process, or a smaller raise than planned.

The second mistake is running too narrow a process. Focusing only on European investors or only on existing relationships limits competitive tension and often results in worse terms. The best-priced Series C rounds in Europe have consistently involved US growth funds in the syndicate, and founders who do not proactively engage transatlantic capital leave value on the table.

The third mistake is neglecting the existing investor base. Surprising existing board members with an external fundraising process, or failing to align them on valuation expectations and participation decisions, creates governance friction at exactly the moment when founder credibility with new investors is most important.

A fourth error is allowing the process to drag past twelve weeks. Momentum decay is a real phenomenon — the longer a Series C process runs without a close, the more new investors wonder what earlier investors saw that gave them pause. Founders should be prepared to make a decision on a term sheet even if it means foregoing a theoretically better offer that is two months away.

Finally, underestimating the operational disruption of the process is a structural mistake. Series C diligence is intensive, and founders who do not delegate day-to-day management during the process frequently see business performance dip mid-raise.

How does Series C funding differ across Europe?

Series C fundraising in Europe is not a uniform experience, and the differences across regional markets are significant enough to affect both strategy and outcome.

The United Kingdom, and London in particular, remains the dominant market for large European Series C rounds. The concentration of US investor offices in London, the depth of the local growth equity ecosystem, and the maturity of sectors such as fintech and enterprise software mean that UK-based companies have more consistent access to the largest round sizes and the most competitive valuation dynamics. The legal infrastructure for venture transactions is also the most developed, reducing execution risk.

The DACH region — Germany, Austria, and Switzerland — has seen its Series C market mature considerably, particularly in B2B software, health tech, and fintech. German founders, in particular, sometimes face a cultural dynamic where overly aggressive valuation expectations are met with investor scepticism, and the preference for conservative financial modelling can be an asset in terms and negotiation even if it occasionally constrains headline valuations.

The Nordics have produced a disproportionate number of large Series C rounds relative to the size of the region's economy. Strong domestic institutional infrastructure, high digital adoption rates, and a culture of building for global markets from day one mean that Nordic Series C companies often have robust international revenue before raising, which appeals to growth investors.

Southern European markets, including Spain, Italy, and Portugal, are at an earlier stage of Series C maturity. Local growth capital is thinner, and companies based there typically need to attract pan-European or US investors to anchor a round at competitive terms.

Eastern European founders raising Series C increasingly relocate their primary entity to Western Europe or the UK during earlier stages, reflecting investor preferences for familiar legal jurisdictions and governance frameworks.
