Molten Bets £100m of Plc Cash on Late-Stage Tech

Molten Ventures has taken a £175 million first close on a new growth fund, putting £100 million of its own cash beside a £75 million British Business Bank cheque. The London-listed firm wants £350 million in total for Series B and later rounds in the UK and Europe. The close was announced on 7 September 2026.

Until another pension, insurer or endowment writes a ticket, the only outside investor is the state bank. The first close is halfway to target, and more than half of the money already in is Molten’s.

Molten Wrote the Larger Cheque in Its Own Fund

The RNS is easy to misread as a conventional fundraise. It is not. Molten Ventures committed the remaining £100 million of the first close from its listed platform and will keep hunting other limited partners for a final size of £350 million. The British Business Bank’s cornerstone is real. It is also the smaller of the two cheques.

HOW THE FIRST CLOSE BREAKS DOWN

A typical buyout or venture general partner puts in a low-single-digit slice of a fund. Here the plc is 57% of the first close and 29% of the £350 million target. The wrapper is a growth fund. The economic event is Molten allocating listed-company capital so it can lead later rounds without stretching the balance sheet on every ticket.

Chief executive Ben Wilkinson has been saying that out loud. When Molten reported full-year results on 9 June 2026, he told shareholders the firm was capital constrained rather than opportunity constrained, and that a cornerstone would let it lead Series B-plus rounds in Europe without leaning too hard on the plc. The 7 September close is that plan made public.

Shares in Molten, ticker GROW, traded at 700.50 pence in London on the morning of the announcement, up 2.6% on the session. Net asset value was 760 pence a share at 31 March 2026, with gross portfolio value of £1,525 million and net assets of £1,324 million. The firm says it manages over £2 billion across the platform.

The Bank Has Been a Shareholder Since 2018

The British Business Bank has held stock in Molten’s listed vehicle since 2018 and has sat in several of the same companies. The growth fund is a new sleeve on an old relationship, not a cold mandate won in a beauty parade.

EIGHT YEARS OF SHARED CHEQUES

1. June 2016: Molten lists in London, then still operating under the Draper Esprit name.
2. May 2018: The firm raises extra public money to back later-stage European tech, already talking about a growth-capital shortage.
3. 2018: The British Business Bank becomes an investor in the listed platform.
4. February 2026: SatVu, a thermal-satellite company in the book, raises £30 million led by the NATO Innovation Fund, with the Bank in the round and Molten leading existing holders.
5. 9 June 2026: Molten’s annual results say a cornerstone for the new Growth Fund is already secured.
6. 27 July 2026: Pension schemes and the Bank unveil plans for a separate UK Scale-up Fund of over £1 billion.
7. 7 September 2026: The Growth Fund takes its £175 million first close, with the Bank’s £75 million as cornerstone.

The Bank has also co-invested with Molten in IMU Biosciences, Thought Machine and Paragraf. Robert Greenwood, senior director for funds at the British Business Bank, treated the new vehicle as part of a wider effort to seed late-stage funds rather than as a one-off favour.

To create deeper pools of late-stage capital for breakthrough technologies, we are helping UK tech investors to launch new growth funds. This commitment is the latest example of that strategy. Molten Ventures is one of the UK’s leading growth investors, with a strong track record of backing fast-growing technology businesses. This fund will help the next generation of tech entrepreneurs scale faster and build global companies from the UK.

Greenwood’s line matches the Bank’s own five-year plan, which tells managers to put more than 60% of venture and growth flow into scale-ups, to invest at least £5 billion in growth-stage funds and companies, and to back at least ten new-to-market growth-stage fundraisings. Molten’s close is one of those fundraisings. It is also a listed firm using state money to enlarge a private sleeve beside a public balance sheet.

UK Growth Rounds Still Lean on Foreign Money

The pitch for the fund is that British and European companies still run out of domestic money when the cheques get large. The Bank’s own market data, published in its Small Business Equity Tracker, shows why that line still lands, and why £350 million is a thin patch on a wide hole.

UK smaller businesses raised £12.3 billion of equity investment across 2,002 deals in 2025, down 4% from 2024, while deal count fell 17%. Growth-stage investment into smaller firms was the resilient slice, up 10% to £5.7 billion even as deal numbers in that band slipped 4%. AI companies took a record £5.4 billion, 44% of smaller-business investment.

THE 2025 EQUITY MARKET THE FUND WALKS INTO

• Concentration: The ten largest smaller-business fundraisings took 23% of that investment, the highest share since 2020.
• US gap: The UK had a 32% venture-capital investment gap with the United States on a GDP-adjusted basis across 2023-2025, widened by outsized American AI rounds.
• Early 2026: Equity into smaller businesses fell 43% in the first quarter, while the wider UK equity total rose 28% to £4.6 billion, with three unicorn megadeals making up about £3 billion of that.
• Bank reach: British Business Bank equity programmes supported 15% of UK equity deals and 16% of investment value in 2023-2025.

Chancellor John Healey, speaking when the pension Scale-up Fund was unveiled, put the political version of the same complaint in one sentence: Britain starts companies and then grows them with other people’s money. He also noted that the UK already has the third-largest venture market in the world, which is why the gap is about later tickets, not about a missing seed scene.

Molten has used that diagnosis before. As Draper Esprit it completed a £176 million raise in 2018 with the same headline about starving European growth companies. The 2026 vehicle is larger on paper, still half-closed, and still asking institutions that sat out the last cycle to come in now.

What the Growth Fund Will Buy at Series B

The mandate is Series B and beyond in the UK and Europe, with a dedicated pool so Molten can take more of a round and hold a larger stake as a company scales. Wilkinson said the firm has already done more than 40 growth-profile deals and invested over £700 million in the past decade, figures it calls top-quartile on returns. Those deals sat on the listed book. The new fund is meant to sit beside it.

SECTORS NAMED IN THE MANDATE

• Space: Satellites and launch, a sleeve that already includes ICEYE, SatVu and Isar Aerospace.
• AI: The same category that took 44% of smaller-business equity in 2025.
• Fintech: The book that produced Revolut and Zopa.
• Quantum, deeptech and hardware: Longer-duration science companies that rarely get a domestic Series C lead.

Wilkinson’s own description of the product is ownership, not logos on a press release. He wants the extra firepower to sit in companies Molten already likes, at the point where a US fund would otherwise set the terms.

There is no shortage of exceptional founders or technology businesses in the UK and Europe; what they too often lack is sufficient growth capital to help them become global leaders. This Fund gives Molten greater firepower to back our highest-conviction companies at Series B and beyond, build meaningful ownership positions and channel capital into the next generation of growth.

That is also how the firm talks about fees. Extra money under management is meant to earn management fees on a private vehicle while the listed shares still give public investors a claim on the same network. Molten has added a dedicated secondaries team and is still working toward a first close of Molten East, a Central and Eastern Europe fund, later in 2026. The Growth Fund is the largest of those third-party sleeves.

Pension Schemes Are Building a Parallel £1bn Pot

Six weeks before Molten’s close, a group of large UK pension providers said they would explore an over £1 billion Scale-up Fund for high-growth British science and technology companies. The British Business Bank is working with that group and intends to invest in partnership. The Office for Investment is supporting the consortium. Market engagement to appoint a manager was opened from the Bank’s side, with asset managers told to make contact.

The pension names on the 27 July 2026 release were Railpen, Nest, Local Pensions Partnership Investments, LGPS Central and Border to Coast. Nest’s chief executive, Ian Cornelius, said the scheme invests for more than 14 million members. Prime Minister Andy Burnham called the plan a vote of confidence in British business. Healey said the new £1 billion would mean more British money behind British scale-ups.

M&G Investments and Schroders are among the firms understood to have applied to run the vehicle, with other asset managers, including early-stage investors, also in the field. Eligibility rules for companies have not been published. Molten’s own role in that contest has not been confirmed by the Bank or by Molten in the 7 September announcement, and it should not be treated as a done appointment.

TWO POTS, ONE STATE BANK

The two vehicles are not substitutes. One is a listed VC putting its own cash to work with a state cornerstone. The other is retirement money that has not yet picked a manager. They share a sponsor in the British Business Bank, and they share a diagnosis. If both fill, later-stage founders get two domestic cheques instead of a flight to California. If the pension vehicle stalls, Molten’s £350 million target becomes one of the few dedicated UK growth pots actually taking money.

Revolut Cash Paid for Balance-Sheet Room

The plc could write a £100 million fund commitment because it has been selling. In the year to 31 March 2026 Molten invested £89 million from the listed book and took £120 million of cash proceeds from realisations. Consolidated cash at year end was £52 million, after £38 million of buybacks. Those figures only work as a base for a new commitment if realisations keep coming, and they did after the year end.

Molten realised a further £63 million from Revolut after 31 March 2026 and kept a stake. It also took cash out of ICEYE in the Finnish radar-satellite company’s Series F. ICEYE’s Series F round raised about €450 million of primary capital led by General Atlantic, with a secondary taking the wider transaction above €1 billion, and valued the company at over €10 billion. At that mark Molten’s holding rose to £317 million, an uplift of £238 million, or 236%, from the 31 March 2026 carrying value, adding about 16% to gross portfolio value after the secondary sale.

Space already accounted for 9% of the portfolio at year end. Isar Aerospace, a German launch company, took a €30 million Molten cheque inside a €270 million Series D in June 2026. SatVu’s £30 million round in February 2026 brought the NATO Innovation Fund and the British Business Bank into a name Molten still leads among existing holders. The Growth Fund’s sector list is a description of deals Molten is already doing, written so it can do more of them without every pound sitting on GROW’s balance sheet.

Since the June 2016 IPO the firm says it has deployed over £1 billion and realised more than £750 million to 31 March 2026, before the extra Revolut cash. Core companies in the book averaged more than $600 million of revenue, with a 70% average gross margin excluding pre-revenue names, and seven of the core were profitable. Wilkinson’s bet is that those names, and the next cohort behind them, still need a domestic lead at Series B and C.

The Second Close Depends on New Limited Partners

The remaining £175 million is the part of this story that is not yet money. Molten said it will continue to seek additional investors. The British Business Bank’s cornerstone is designed to make that easier. Cornerstones exist so other institutions can point to a first, serious name in the cap table. In this close that name is a state development bank, and the second name is the manager itself.

Insurance companies, endowments and the same pension schemes now circling the Scale-up Fund are the obvious next calls. They are also the investors European venture has failed to lock in at American rates. Wilkinson’s June results letter already framed the cornerstone as a device to de-risk a first close and then pull further institutional limited partners in behind it. The first half of that sequence is done. The second half is the actual test of the bet.

A £350 million growth fund that ends up 57% Molten and 43% British Business Bank, with a thin layer of outside money on top, would still let the firm lead more rounds. It would not be the deep pool of long-term institutional capital Wilkinson described on 7 September. It would be the listed vehicle plus the state, which is where UK late-stage financing already sits when US funds do not show up.

The 7 September close makes that choice visible. Molten has put £100 million of plc capital on the table, the British Business Bank has put £75 million beside it, and the rest of the City has a fund document, a sector list and a half-empty £350 million target to answer.
