Series A Fundraising in 2026: What European Investors Now Expect

According to Crunchbase, European venture funding reached $58 billion in 2025, a gain of only around 9% on the year before. Within the year, quarterly totals moved from $12.6 billion in Q1 and Q2 to $13.1 billion in Q3 and $16.6 billion in Q4. KPMG's Venture Pulse, which uses a wider definition, counts $85.3 billion across 8,626 deals. The difference between the two totals is a useful warning: any Series A benchmark depends on whose data and whose definition you are reading.

The more important point is where the growth sat. Crunchbase defines early-stage as rounds above $3 million and up to $15 million, which brackets the typical Series A round size. That band raised $5.4 billion in Q1, $5 billion in Q2, $6.1 billion in Q3 and $5.3 billion in Q4. The growth in the total came from late-stage funding, which reached $9.2 billion across 87 deals in Q4, up 65% by amount on a year earlier.

For a founder, this means the headline recovery is not a tailwind for your round. The early-stage pool was broadly flat across the year, with more than 250 rounds closing in Q4, so you are competing for roughly the same number of cheques as before. Investors with new capital to deploy are choosing between a larger number of candidates, and the cheapest way for them to decide is to ask for more evidence.

What to do: set the evidence bar before you set the timeline. Decide which metrics you can show with definitions an outsider will accept, and delay launching the process until those exist. A round launched on a thin pack tends to run for months, and a long, visible process damages the price more than a short delay in starting.

There is also a sequencing point for boards. Investors read a flat early-stage market as a sign that pricing power sits with them, and they behave accordingly: more diligence, more reference calls and a stronger preference for companies where another investor has already shown conviction. Founders can use this by securing a credible lead early and building the round around that lead, rather than running a wide process and hoping momentum appears. A single informed lead with a clear view of the evidence is worth more than ten polite follow-ups.

A practical test of readiness is to ask whether your pack would survive a hostile reading. Imagine an investor with no prior interest in your sector reviewing the numbers alone, without the benefit of your narrative. If the revenue, retention and efficiency figures make the case unaided, the deck can be short. If they need a long explanation, the explanation is usually a sign that the underlying evidence has not yet matured enough for a Series A.

Carta reports that median ARR at Series A was $2.8 million in 2025, up 22% from $2.3 million in 2024. CRV, measuring revenue rather than ARR, puts the median at $2.5 million, roughly 75 percent higher than in 2021. The two figures differ because the definitions differ, but they point the same way: the revenue that earns a Series A meeting has risen sharply in four years, and a company with $1 million of ARR is now below the median rather than at it.

CRV also reports Series A median round sizes ranging from roughly $5 million to $15 million in 2025. Round size matters because it sets what investors need to believe about the next stage. A founder raising at the top of that range is asking the investor to underwrite a plan to a Series B, not to fund the discovery of a go-to-market model. The motion has to be demonstrated, not hoped for.

Equidam's data adds a European caution. Across early-stage deals from pre-seed to Series A, it found median valuations in Europe averaged $6.54 million over 2020 to 2025 against $14.64 million in the US, with European funding targets 46% smaller. These are blended early-stage figures, so they do not give a Series A price. They do show that European founders should not borrow US revenue multiples or round sizes when setting expectations.

What to do: define ARR in writing before the first meeting. State whether it includes pilots, usage-based revenue or contracted but not yet live customers, and reconcile it to invoices. Investors who find a definitional gap in diligence rarely treat it as an accounting detail; they treat it as a question about the quality of everything else in the pack.

A useful discipline is to separate the metrics you can prove from the metrics you are projecting, and to label them differently in the deck. Investors forgive a forecast that misses; they do not forgive a historical figure that changes between meetings. Treat the first conversation as a test of consistency. If the number in the deck, the number in the model and the number in the data room are the same, the investor spends the rest of the process testing the business instead of testing you.

The difference between the Carta and CRV medians is itself instructive. One counts annual recurring revenue and the other counts revenue, and an investor will ask which one you are quoting and why. Founders who volunteer the definition, and show both figures where they differ, remove a source of doubt before it appears. The point is not to maximise the number but to make it the one figure that will never need to be corrected later in the process.

CRV sets out the retention ranges it sees at Series A: 100% net revenue retention as the baseline and 110% to 120% as competitive. It also reports that companies with net revenue retention above 100% grow 1.5 to three times faster than those below. For a founder, retention is therefore not just a quality signal; it is the clearest predictor an investor has of whether the next round of capital compounds or leaks.

Burn multiple is the second test. CRV defines a burn multiple of one times as burning $1 for every $1 of new ARR, so a lower figure means more growth per pound or dollar spent. The metric matters because it is hard to flatter. It combines the sales motion, the cost base and the retention rate into one ratio that an investor can calculate from your management accounts in an afternoon.

The third pressure is acquisition cost. CRV reports that customer acquisition costs rose 14% in 2025. If your cost to win a customer has risen with the market while your price has not, the pack needs to show it and explain the response. An investor will find the trend anyway; presenting it first, with channel-level payback, converts a weakness into evidence of management control.

What to do: prepare an efficiency page with three exhibits: burn multiple by quarter, net revenue retention by cohort and acquisition cost with payback by channel. Keep the definitions identical to those in your management accounts. Where a metric looks weak, add the action taken and its measured effect, so the investor sees the trend direction as well as the level.

Founders sometimes ask whether a stronger growth rate can offset weak efficiency. In the current market it rarely does, because investors have seen how quickly an inefficient motion exhausts its funding. A better trade is to present a moderate growth rate with a visibly improving burn multiple, and to explain what the next tranche of capital changes. Credible improvement in the ratio is more persuasive than a single strong quarter, which investors will discount as potentially unrepeatable.

Another reason efficiency matters is that it determines how much of the round is spent on growth rather than on correcting the motion. An investor who sees a falling burn multiple and rising retention can model the next two years with confidence, and can justify a larger cheque. An investor who sees the opposite must price in a period of repair. The pack should therefore show the direction of travel and the management decisions that produced it.

CRV reports that the median gap between seed close and Series A close reached 616 days, more than 20 months, in Q2 2025. Many seed rounds were sized on an assumption of an 18-month journey. A company that hits its milestones on time can therefore still arrive at a Series A process with less runway than the market now expects it to need.

Carta's Q3 2025 data show why the stakes at this step are high. Seed rounds were nearly 40% of new venture rounds but only 9.4% of cash raised, while Series A took 24.9% of all capital, more than any other stage. Capital is concentrated in the companies that cross the gap. The market is not short of money at Series A; it is selective about who reaches it.

There is some reassurance for companies that do cross. Carta reports that about 17% of new venture rounds in Q3 2025 were down rounds, the lowest quarterly rate in nearly three years. Investors who have repriced their expectations are writing cheques at more stable valuations, which favours founders whose pack is credible and whose asks are realistic.

What to do: treat runway as a planning variable in the seed round. Model two scenarios, a Series A at the median timing and one at a longer gap, and agree with existing investors in advance how a bridge would be structured. Starting the conversation about a bridge before it is needed signals planning; starting it after the process stalls signals weakness.

For founders whose seed round is already ageing, the practical consequence is to treat the 20-month median as a trigger for contingency work rather than as a target. Review monthly cash against the plan, identify the discretionary spend that could be paused without damaging the motion, and decide in advance the date at which the contingency begins. A company that has a prepared option to extend runway negotiates from a position of strength; one that discovers the option under pressure does not.

Founders should also consider how the gap interacts with hiring. A longer interval to the next round means key hires made after the seed round must pay back within a longer window, and the cost of a mistaken hire is higher. Where the plan relies on a senior sales leader, agree the success measures and the review date in advance. Doing so protects runway and provides evidence of the motion that the Series A investor will want to see.

Carta reports that the median Series A pre-money valuation reached a record $49.3 million in Q3 2025, and that the median seed pre-money valuation was $16 million. Carta's customer base is weighted to the US, and the figures are medians across a platform, not a guide to what a specific European company will receive. Quoting them to an investor in London or Berlin invites a conversation about the data rather than the business.

Equidam's comparison shows the practical effect in Europe. Average target dilution was 8.88% in Europe against 7.17% in the US, because European founders raised less at lower valuations and gave up a larger share for it. That does not translate directly into Series A terms, but it does show that European rounds are priced and structured differently from the US numbers that dominate headlines.

The risk for founders is anchoring. A target set by a US headline produces an ask that European investors reject, and a rejected ask creates the visible, extended process that depresses price. The founders who close cleanly tend to arrive with a comparable set drawn from recent rounds in their own market and a view of the dilution they are willing to accept.

What to do: build a comparable set of at least a dozen recent European rounds in your category, with stage, revenue at raise and implied multiples where disclosed. Agree the dilution range with your existing board before approaching investors. Use the set to explain your price, not to demand it; an investor who understands your reasoning will often negotiate on terms rather than on headline value.

A discipline we recommend is to keep a one-page pricing rationale alongside the comparable set. It should state the dilution the founders are willing to accept, the milestones the round must fund and the evidence that supports the asking valuation. When an investor challenges the number, the founder can respond with reasoning instead of defensiveness. In our experience, a clearly reasoned ask that is slightly high is received better than an unexplained ask that is slightly low, because it shows control of the business.

Crunchbase reports that close to 40% of European funding in Q3 2025 went to AI-related startups, totalling $5.2 billion, up from $2 billion in Q3 2024. For the full year, around $17.5 billion went to AI against just over $10 billion in 2024. Investor attention and partner time are following the money, and a growing share of Series A meetings will be framed by AI comparisons even for companies that are not AI companies.

The implication is different for the two groups. A non-AI company faces a narrative disadvantage: it is competing for time with businesses that can describe a step-change in the product. The answer is not to bolt on an AI story but to be sharper on the evidence, because retention, efficiency and a repeatable motion are indifferent to sector fashion and are the points on which a disciplined investor will still lean.

An AI company faces the opposite problem. Revenue quality is scrutinised more closely, because investors have seen usage-driven revenue that does not renew and pilots that do not convert. A founder in this position should expect questions on gross margin after inference costs, contract length and whether revenue is committed or consumption-based, and should bring the answers before they are asked.

What to do: decide which group you are in and prepare accordingly. Non-AI founders should lead with the efficiency page and the cohort data. AI founders should lead with revenue quality: committed versus usage revenue, renewal evidence and margin after model costs. In both cases, avoid sector language that cannot be supported by a number in the pack.

Whichever group applies, the investors who matter will compare you with the best versions of both. A non-AI company with excellent retention is more attractive than an AI company with unexplained revenue, and the reverse is also true. The practical lesson is to avoid defining yourself by sector in the first minute of the meeting and to lead instead with the metric on which you are strongest, supported by the cohort data that shows it is not an accident.

Investors ask about market size because they want to know whether the business can become large. A total addressable market figure is a weak answer, because it is an assertion. A repeatable sales motion is a stronger answer, because it is a measurement: it shows that a defined buyer can be reached, converted and retained at a cost the business can sustain, and it implies that doing the same thing more times produces a larger business.

Evidence of repeatability has a recognisable shape. It includes a stable sales cycle across cohorts, win rates by source, an average contract value that does not depend on one or two large customers, and a payback period that investors can compare with the pack's retention. CRV's report that acquisition costs rose 14% in 2025 is a reminder that investors will test whether the motion survives rising costs, not just whether it worked once.

For regulated or partly regulated raises, process discipline matters as much as the pack. Communications with investors may be subject to the UK financial promotion regime, and founders should take advice from an FCA-authorised firm before circulating materials widely. Keeping a clear record of what was shared with whom also helps during diligence, where inconsistencies between versions of a deck and the data room are a common source of friction.

What to do: run a 90-day pre-raise programme. In the first month, lock definitions and rebuild the cohort data. In the second, test the motion with a deliberate increase in outbound or channel activity and record the effect on cost and conversion. In the third, build the data room, shortlist investors by fit and open conversations. Founders who follow this sequence tend to meet fewer investors and close faster.

Finally, remember that the sales motion is also the strongest answer to the question of what happens after the round. Investors are underwriting a plan to scale the team, and the first hires after funding will usually be in sales and customer success. If you can show how the founder-led motion has been documented, taught and partially delegated, you reduce the key-person risk that investors price into every early-stage company, and you make the next round easier to raise.
