Who Actually Writes Pre-Seed Cheques — Stage Appetite Across US, EU and UK Investor Theses

The stage-appetite gap founders never see coming

Only 50.6% of UK investors in FMD's parsed thesis corpus (n=542) state explicit pre-seed appetite — versus 79% who state seed appetite — a 28.4-point gap that makes the UK's pre-seed market the tightest of the three regions studied. Founders read "early-stage fund" on a website and assume it means pre-seed and seed are equally in scope. The data says otherwise, and the gap is widest exactly where founders can least afford it: the round before there's a product, revenue, or sometimes a full team.

This piece is built from FMD's own parsed corpus of investor theses — not survey responses, not self-reported check sizes, but the stage language funds actually publish. As of 2026-07-07, the full dataset spans n=1,679 investors across the US, EU, and UK. The methodology behind how we tag "pre-seed" versus "seed" appetite is documented separately: see methodology.

Why 'early-stage investor' doesn't mean what founders think it means

"Early-stage" is a marketing term, not a stage definition. It gets applied to funds that only write checks from seed through Series A, funds that do pre-seed exclusively, and funds that do both — with no consistent boundary. A fund's public thesis is the only reliable signal of what stage it actually funds, and even then, only if the thesis states stage appetite explicitly rather than implying it through portfolio examples. FMD's corpus draws this line at the sentence level: if a thesis names "pre-seed" or "seed" as a stage it invests in, that investor is tagged as having stated appetite for that stage. If a thesis only says "early-stage" without a stage-specific term, it is tagged as ambiguous, not counted toward either.

The data — stage appetite across 1,679 parsed investor theses (US, EU, UK)

Across the full corpus, seed appetite is stated far more consistently than pre-seed appetite in every region — but the size of that gap varies enormously by geography.

US: 86.4% of investors claim seed appetite, but pre-seed is a different club

86.4% of US investors in FMD's corpus (n=872) state explicit seed-stage appetite. Only 61.2% of the same pool state pre-seed appetite. A US investor who publishes a thesis is more likely than not to fund seed. That same investor is meaningfully less likely to touch pre-seed, and the gap between the two — 25.2 points — is real but smaller than the UK's. Context from the broader market helps explain why: Crunchbase reports that seed funding in 2025 broke records around big rounds and AI, with the US far in the lead, and that seed-stage capital is skewing larger and more competitive than ever, with roughly 1 in 10 seed deals over $200,000 in 2025 landing in the $10 million-and-over bracket. When "seed" rounds increasingly look like what used to be Series A, funds calibrated for that check size have less structural reason to also write pre-seed cheques.

UK: only 50.6% state pre-seed appetite vs. 79% for seed

Only 50.6% of UK investors (n=542) state pre-seed appetite, compared with 79.0% who state seed appetite. This is the largest pre-seed/seed split of the three regions and the lowest absolute pre-seed appetite figure. It means a UK founder emailing a random "early-stage" fund off a portfolio page has roughly a coin-flip chance the fund even claims to do pre-seed at all — regardless of fit, sector, or traction. The UK Pre-seed and Seed Investment Trends Report H1 2025 from Robot Mascot and Carta's State of Pre-Seed: 2025 in Review both point to the same underlying dynamic covered in the next section: fewer funds are structured to write true pre-seed-sized checks, even as more claim to be "early-stage."

EU: 90.8% seed appetite — the highest of the three regions

90.8% of EU investors in FMD's corpus (n=174) state seed appetite — the highest of the three regions studied — while 66.7% state pre-seed appetite, also the highest pre-seed figure of the three. The EU pool is smaller (n=174), so figures should be read with wider confidence intervals than the US or UK numbers, but the direction is consistent with Concept Ventures' Zero to One report on European pre-seed and Dealroom's Europe Tech Update Q1 2025, both of which describe a European early-stage market where dedicated pre-seed vehicles have proliferated faster, relatively, than in the UK specifically.

Why the UK pre-seed gap exists (round-size inflation, SAFE adoption, fund structuring)

Three structural forces explain most of the UK's 28.4-point gap.

Round-size inflation. As seed rounds get larger — a trend Crunchbase documents in the US and that is visible in UK data too — funds raise bigger vehicles to write bigger checks at seed, and the smallest, earliest checks fall outside their model entirely. A £2-3M fund can write ten £200-300K pre-seed checks; a £60M fund calibrated for £1-2M seed checks structurally cannot, without diluting its ownership targets across too many companies.

SAFE and pre-seed instrument adoption lagging the US. The US pre-seed market matured around SAFEs as a fast, cheap instrument for very early checks. UK adoption of equivalent instruments (ASAs, advance subscription agreements) has been slower and less standardized, per VC Lab's analysis of competing funding stages, which raises the fixed legal cost of writing a small early check relative to the US — pushing some UK funds to skip pre-seed and wait for a priced seed round instead.

Fund structuring and LP expectations. UK seed and Series A funds are frequently structured around ownership targets (10-20% at entry) that are difficult to hit with pre-seed-sized checks without also reserving significant follow-on capital. Funds that haven't raised a dedicated pre-seed vehicle often default to stating seed as their entry point, even if they occasionally do earlier deals informally — which is exactly the ambiguity FMD's thesis-parsing methodology is built to strip out.

What the 30-point US seed vs. UK pre-seed gap means for founders' funnel math

Compare US seed appetite (86.4%) against UK pre-seed appetite (50.6%) and the gap is 35.8 points — nearly 36 points between the easiest stage/region combination in this dataset and the hardest. Practically: a UK founder raising a pre-seed round needs to contact roughly twice as many investors to reach the same number of qualified conversations as a US founder raising seed, purely on stated-appetite math, before any consideration of fit, sector, or traction quality. This is funnel math, not sentiment. If a founder's target list isn't pre-filtered for stated stage appetite, roughly half of UK outreach at pre-seed is structurally wasted before the first email is opened.

How to read 'pre-seed friendly' language in a thesis without wasting outreach

Three checks before adding an investor to a pre-seed target list:

1. Does the thesis name "pre-seed" explicitly, or only "early-stage"? Only the former counts as stated appetite in FMD's tagging.
2. Does the thesis state a check-size range that fits a pre-seed round (typically under $500K-$1M in the US, under £300-500K in the UK)? A stated range is a stronger signal than stage language alone.
3. Has the fund published a pre-seed deal in the last 12 months that matches its stated thesis? Absence isn't disqualifying, but it's a flag worth weighing.

Regional playbook — sequencing your raise across US/EU/UK investor pools

For UK-based pre-seed founders, the practical implication is to weight outreach toward the 50.6% of investors with stated pre-seed appetite rather than the broader "early-stage" pool, and to specifically see UK funds with confirmed pre-seed appetite before spending time on funds that only state seed. For US founders, the seed pool at 86.4% is wide, but the pre-seed pool at 61.2% is narrower than commonly assumed — treat pre-seed outreach with the same filtering discipline as UK founders do. For EU founders, both stages show the highest stated appetite of the three regions (66.7% pre-seed, 90.8% seed), but the smaller sample (n=174) means less redundancy in the investor pool — a rejection removes a larger share of the addressable market than in the US.

Across all three regions, the fix is the same: browse investors by stage appetite rather than by geography or sector alone, and match your deck to investors with stated pre-seed or seed appetite before building an outreach list from a generic "early-stage VC" search.

Methodology — how FMD parses investor theses for stage appetite

FMD's corpus tags stage appetite directly from each investor's own published thesis language — website thesis pages, fund one-pagers, and publicly stated check-size ranges — not from portfolio inference or third-party databases. An investor is tagged as having "stated pre-seed appetite" only if their own thesis names pre-seed as an investable stage; the same rule applies to seed. Ambiguous terms like "early-stage" alone, without a named stage, are excluded from both categories rather than double-counted. As of 2026-07-07, the corpus totals n=1,679 investors (US n=872, UK n=542, EU n=174). Full methodology, including how ambiguous and multi-stage theses are handled, is documented at methodology.
