Passion Capital Closes €46M Seed Fund IV to Defend London's First-Cheque Franchise
TL;DR
London's Passion Capital has closed Passion IV, its fourth seed fund, at €46 million ($55 million), alongside two SPVs. The vehicle is already deployed into 13 companies spanning AI, fintech and enterprise risk, and it lands on the back of a 2025 distribution cycle that returned €72 million to LPs, more than the size of any of Passion's prior funds. For a firm famous as the first institutional cheque into Monzo, GoCardless and Tide, Fund IV is less about scaling AUM and more about defending a first-cheque franchise in a European seed market where everyone is chasing AI and almost nobody is disciplined about portfolio construction.
Key Takeaways
The first-cheque franchise is back in vogue. Passion has resisted the industry-wide drift into multi-stage platforms and is staying at seed, the only stage where pricing hasn't completely decoupled from fundamentals. In a market where Accel just raised $5B for growth and Sequoia is chasing the OpenAI IPO, Passion's bet is the opposite direction: small, concentrated, and early.
DPI is the moat. A reported 23% net IRR and 2.5x DPI across prior vintages, with €72 million returned to LPs in 2025 alone, is what lets a boutique seed fund raise in a brutal LP environment. Most European seed managers have IRR on paper but have not shipped cash. Passion has.
Five fintech unicorns from 100 companies is a top-decile ratio. Monzo, GoCardless, Tide, Marshmallow, PolyAI (arguably the most famous conversational AI company in the UK) and Lendable all trace back to Passion's early cheques. The firm's pattern recognition on UK fintech is effectively unrivalled.
Fund size discipline is the real contrarian call. €46 million for fourth-fund seed investing from a firm that could credibly raise €150M+ is a statement. Small funds with concentrated ownership beat big funds with dilution, and Passion is voting with its own fee income.

Fund Size: €46 million ($55 million), final close

Why This Fund Matters
European seed is in a strange place. On one hand, it has never been more crowded. Solo GPs, operator funds, corporate venture arms and accelerator follow-ons all compete for the first cheque. On the other hand, LPs have rarely been more skeptical, with many having pulled back after a dismal 2022-2024 DPI drought from European vintages. In that bifurcated environment, the funds that can actually close are the ones with proven exits and a differentiated brand. Passion has both.
Passion's pitch to LPs is also increasingly about the thesis, not just the logos. The fund is leaning into enterprise risk software and applied AI for financial services, two areas where the UK has an unusual structural advantage: the world's densest fintech ecosystem sits inside the world's most sophisticated regulatory sandbox. That is the kind of edge you cannot replicate from Menlo Park.
The decision to keep the fund small also signals something important about where the firm thinks alpha lives. Seed returns are driven by ownership at entry and concentration, not AUM. A €46 million fund writing 13 cheques into first-money-in positions can still return the fund on a single breakout, which is mathematically almost impossible for the mega-funds now raised by Sequoia, Accel and General Catalyst.
Finally, this close is a quiet rebuke to the argument that European seed has been permanently disrupted by American capital and AI mega-rounds. Capital still flows to the funds that ship DPI. Passion shipped €72 million of it last year.
The Team
Passion was founded in 2011 by Eileen Burbidge, Robert Dighero and Stefan Glaenzer. The current partnership deploying Passion IV includes Robert Dighero, Andrew Diamond, Will Martin, Sarah Turner and Greg Bennett, CFA. The team has collectively backed over 100 companies from seed, producing five fintech unicorns, and has built a reputation in London for being reachable, opinionated and willing to move faster than nearly any other UK seed firm on conviction deals. Their track record of exits in 2025 alone (Ravelin acquired, Tillo, Xelix, and the Mollie acquisition of GoCardless) is the proof-of-work that translates into LP re-ups.
Early Portfolio
Passion IV has already deployed into 13 companies, though the firm has not publicly disclosed each name. Historical portfolio highlights include Monzo, GoCardless, Tide, Marshmallow, Butternut Box, PolyAI and Lendable — a blue-chip set of seed investments that is almost certainly the most valuable in the UK by any DPI-weighted measure.
What This Means for Founders
If you are a UK or European founder building in AI, fintech or enterprise risk at pre-seed or seed stage, Passion should be on your short list. They lead or co-lead, they move fast, and they genuinely act as first-cheque investors rather than running a stealth multi-stage platform. The partners are hands-on, especially Robert Dighero, who is known to pattern-match on fintech metrics more quickly than almost any other UK investor.
One important nuance: because Passion IV is concentrated into roughly 20-25 companies across its three-year deployment window, they are genuinely selective. The implication is that a pitch to Passion should demonstrate why you are in the top decile of whatever category you are building in, not the top quartile. This is the opposite of how most seed funds operate today.
Fund Momentum Take
This is one of the most credible seed raises in Europe this year, not because of size but because of DPI. In a fundraising market where most LPs have become allergic to European seed stories ("great IRRs, no cash"), Passion has done the thing that everyone says is impossible: repeatedly returned capital. That gives them a durable LP base that lets them stay small, and that in turn lets them write first cheques without the performance drag of a bloated platform.
Our bet is that Fund IV becomes a top-quartile vintage for European seed, with the caveat that it is deploying into a frothy AI/fintech environment where entry multiples are uncomfortable. The real risk is not the partners, it is the market: can anyone paying today's seed prices in AI actually generate 3-5x DPI? Passion's historical pricing discipline gives us more confidence than the median, but less than the marketing.
The contrarian risk is also worth naming. Fund IV is smaller than Fund III. In most VC brands, that would be a signal of franchise erosion. Here, we read it the other way: it is a signal of discipline in a market where every peer is raising bigger to justify higher management fees. If Passion is right and seed returns are driven by concentration, Fund IV may be their best vintage yet.
