Five smaller UK rounds, Dogtooth, HIVE, Pixel-Flo, TaiSan and Kord, raised a combined £41.5m across robotics, silicon, displays, batteries and fintech, most reported only by Tech.eu.

Key takeaway

Beneath the megadeals, five sub-£15m rounds show the cross-sector seed tier the Bank called thin still stirring.

Dogtooth took £14m for AI agricultural robotics, one of five smaller UK rounds that landed under the week's headline raises. HIVE raised £11.2m for industrial AI silicon, Pixel-Flo a £5.25m seed for MicroLED display manufacturing and TaiSan £4.65m for battery materials, all reported in the Tech.eu weekly recap ¹. Separately, FinSMEs reported the London fintech Kord raising a £6.4m Series A on 8 July, led by Guinness Ventures ².

Take the aggregator figures as indicative; only Kord carries a named lead and a firm date. Together they sketch the materials, robotics and silicon seed tier the Bank's own tracker called thin .

It is the same band that produced fusion startup Astral Systems' £23m round and epilepsy-biomarker firm Neuronostics : unglamorous, sub-£15m and spread across sectors rather than piled into AI.

Deep Analysis

In plain English

Alongside the week's headline deals, five smaller UK companies working on very different technologies each raised money: Dogtooth (robots that pick fruit and vegetables), HIVE (computer chips for industrial AI), Pixel-Flo (a display technology called MicroLED), TaiSan (materials for batteries) and Kord (a London financial-technology firm). Together they raised about £41.5m, a fraction of the size of the week's biggest single deals, showing that smaller, early-stage UK companies across many industries are still finding funding even while the largest rounds dominate the headlines.

Deep Analysis

Root Causes

These five rounds sit in the sub-£15m tier the Bank's own tracker showed shrinking as AI captured a record 44% of 2025 equity value; Dogtooth, HIVE, Pixel-Flo and TaiSan span agriculture, silicon, displays and batteries precisely because deep-tech seed capital has thinned across sectors rather than concentrating in one.

Kord's £6.4m Series A led by Guinness Ventures differs in structure rather than size: a domestic lead investor writing a priced round, at the same cheque size where StirlingX and Neuronostics also raised in June, both similarly domestic-led.

What could happen next?

Meaning
Deep-tech seed funding is thinning across sectors rather than disappearing entirely, with domestic-led rounds like Kord's persisting alongside foreign-heavy megadeals.

Different Perspectives

Nscale and Open Cosmos

Nscale chose the New York Stock Exchange for its listing on 18 September, putting Britain's largest AI infrastructure bet to American public investors rather than British ones. Open Cosmos took the opposite route four days earlier, raising nine figures from an all-domestic syndicate on five years of profit, evidence that staying is possible when the balance sheet allows it.

Dame Chi Onwurah and the Science, Innovation and Technology Committee

Committee chair Dame Chi Onwurah wrote to government on 7 September asking how Matt Clifford's conflict at ARIA arose and what safeguards protect its governance, and expects a detailed response. Her question has not yet been put to the Sovereign AI Unit, whose own chair sits at a venture capital firm while overseeing state AI equity.

The Entrepreneurs Network

The Entrepreneurs Network's founder survey found 65% say Britain is easy to start a business in but only 14% say it is easy to scale one, with 82% negative on tax and 74% finding investment hard to access. On this reading the constraint is regulation and tax, not the capital-vehicle design the state keeps adjusting.

New Economics Foundation

The New Economics Foundation argues fiscal accounting rules, not political will, cap what Britain's state capital vehicles can do. Matching the KfW and Bpifrance benchmark of 1% of GDP would need the National Wealth Fund to deploy roughly GBP21bn a year by 2028-29, about four times its current capacity.

Competition and Markets Authority

The CMA's 8 September report on public procurement asked whether Britain's roughly GBP400bn state-spending system is built to grow high-potential firms rather than simply widen SME participation. Its Recommendation 5 calls for a dedicated frontier-technology procurement framework, an official acknowledgement that today's design may serve the wrong target.

Highland Europe

Highland Europe, the growth-equity firm behind a €1bn-plus fund, took €65m from the British Business Bank into its Technology Growth Fund VI on 30 July via British Patient Capital. For a Geneva-based growth investor, the Bank's cheque is routine cornerstone capital, unrelated to which Whitehall department currently claims to sponsor UKRI.
