Haatch Opens Its 15th SEIS Fund as Demand for Early Stage Tax Relief Keeps Outrunning Supply

Pre-seed founders outside the AI hype cycle are having a harder time raising than the headline numbers suggest. The British Business Bank's Small Business Equity Tracker 2026, published in July, found that UK equity investment into smaller businesses fell 4 per cent to 12.3 billion pounds in 2025, with seed stage deals down 27 per cent and venture stage deals down 13 per cent. AI related deals accounted for 44 per cent of all investment, the highest share on record, which means a shrinking pool of capital is being split even more unevenly for founders building outside that category.

Against that backdrop, Haatch has opened its fifteenth Seed Enterprise Investment Scheme fund, with a data room that went live to investors this week and, according to the firm, is already seeing demand run ahead of supply. Haatch is a B2B SaaS focused pre-seed and seed investor that has run its SEIS programme through a partnership with equity crowdfunding platform Crowdcube, and SEIS 15 continues that model.

The structure is designed to widen who can participate, not just how much is raised. Crowdcube's partnership with Haatch lowers the minimum investment to 2,000 pounds, roughly a fifth of the 10,000 pound minimum that is typical for SEIS funds run through wealth platforms. That matters because SEIS carries the most generous relief in the UK's venture capital schemes, up to 50 per cent income tax relief on investments up to 200,000 pounds per investor in a single tax year, plus capital gains exemptions on qualifying disposals. A lower minimum ticket means a meaningfully wider pool of UK taxpayers can access that relief alongside exposure to early stage B2B SaaS companies, rather than the benefit sitting mainly with people who can write five figure cheques.

Haatch will deploy the fund across a target portfolio of 10 to 15 pre-seed B2B SaaS businesses over roughly 12 months, following the pattern of its earlier SEIS vehicles, which have backed companies including Native Teams, Odin, Ningi, Primis and DL Academy. The SEIS company level cap itself has not moved. Companies can still raise up to 250,000 pounds in total through SEIS, a figure unchanged since April 2023 and left untouched in the Autumn 2025 Budget and the Finance Act 2026, even as EIS and VCT company limits were widened from April 2026. That stability is arguably part of what makes SEIS dependable for fund managers like Haatch to plan around, at a time when so much else in the funding environment is in flux.

The wider pattern is what makes SEIS 15's early demand worth watching. Successive Haatch SEIS raises, and similar vehicles from other managers, have been reported as selling out ahead of schedule this year, at the same time as the British Business Bank's data shows seed stage deal volumes falling across the market overall. Read together, that suggests the constraint on early stage capital for non-AI founders is not really investor appetite. Retail and semi retail investors clearly want SEIS exposure when it is priced accessibly. The constraint looks more like structural access, in ticket sizes, platform reach and awareness, than a genuine shortage of people willing to back pre-seed founders.

That is also where the sector's broader direction of travel is heading. Alongside funds lowering their minimum tickets, there is active work across the market on whether tokenised SEIS shares paired with scheduled PISCES trading windows could eventually shorten the realistic liquidity horizon for early backers without disturbing the underlying tax relief. Haatch's SEIS 15 is not a tokenisation story.

It is a reminder of why that work matters: every mechanism that lowers the practical barrier to backing a pre-seed founder, whether that is a smaller minimum ticket on Crowdcube today or earlier liquidity through PISCES tomorrow, changes who gets to participate on both sides of the cap table.

Key takeaways:

• UK seed stage equity deals fell 27 per cent in 2025 as AI took a record 44 per cent share of total investment, per the British Business Bank's Small Business Equity Tracker 2026.

• Haatch has opened SEIS 15 via Crowdcube, with a data room live this week and demand reported to be running ahead of supply.

• The Crowdcube partnership lowers the minimum SEIS investment to 2,000 pounds, around a fifth of the typical 10,000 pound minimum, widening access to SEIS's 50 per cent income tax relief.

• The SEIS company raise cap remains 250,000 pounds, unchanged since 2023 and untouched by the Autumn 2025 Budget, even as EIS and VCT limits widened from April 2026.

• Fast selling SEIS raises alongside falling overall seed deal volumes point to a structural access problem rather than a lack of investor appetite.

Earlier milestones: Haatch SEIS 14 and its backers

Haatch's previous fund, SEIS Fund 14, closed to new investment on 11 July 2026 after reaching its £4.5 million hard cap, two days after Haatch told investors that only £500,000 of capacity remained. It was also offered through Crowdcube from £2,000. Haatch says it was the fifth consecutive Haatch SEIS fund to be fully subscribed.

Haatch typically invests before companies reach £1 million in annual recurring revenue. British Business Investments, the commercial arm of the British Business Bank, has committed up to £20 million across Haatch funds and a further £25 million to a Haatch-managed angel syndicate platform. Haatch won Best SEIS Investment Manager at the 2025 EISA Awards and Seed VC of the Year at the UK Business Angels Association Awards.
