Key takeaway

All3 raised $25m on 29 April for agentic defence factories spanning Birmingham, France, Germany and Ukraine.

All3 raised a $25 million seed on 29 April 2026 led by RTP Global, with SuperSeed, Begin Capital, s16vc and VNV Global participating 1. The Birmingham-based company plans to build agentic factories for defence, robotics and aerospace clients, with declared expansion into France, Germany and Ukraine.

All3's customer set tracks directly onto the British procurement architecture stood up over the last six weeks. Sprint and Zig-Zag, the private-finance mechanisms made permanent within the Defence Investors' Advisory Group on 22 April , are designed to catalyse precisely this customer base. The MOD's £20m fund underwrites the same group of buyers; All3 is reading the policy stack and pricing accordingly.

An All3 agentic factory in Birmingham looks much the same as one deployed forward in Mariupol, which is why the planned geography spans Ukraine alongside German and French customers. NATO-adjacent aerospace primes are increasingly placing build capacity close to operational theatres; the company is positioning to win procurement in both directions across The Alliance.

RTP Global leading reflects the international-VC anchor pattern visible elsewhere this window. The named investor mix sits alongside Forest's specialist mobility-VC stack and the British Business Bank regional vehicle behind Third Space Learning, suggesting the post-VCT-cut market is sorting into discrete capital pools by sector rather than collapsing into one dominant template. Defence-tech is becoming an asset class with its own anchor funds, not a niche of generalist venture.

Deep Analysis

In plain English

An agentic factory is a manufacturing facility where software makes most of the production decisions, such as when to switch between parts, how to adjust a robot's movements for different tolerances, and when to flag quality problems, without a human operator authorising each step. All3 builds the software that runs these decisions. Its target customers are defence, robotics and aerospace manufacturers: companies that need very precise parts made in relatively small batches, which is exactly where manual processes are slowest and most error-prone. The Birmingham base is not coincidental: the West Midlands has a dense cluster of precision engineering companies supplying the UK aerospace and defence sector. All3 is building its product where its first customers already operate.

Deep Analysis
Root Causes

All3's Birmingham location and defence focus reflect a specific industrial geography. The West Midlands hosts roughly 60% of UK aerospace tier-two and tier-three suppliers, mostly small factories making precision components for Rolls-Royce, GKN and BAE Systems. Those factories run on manual processes and proprietary CNC programs because upgrading them requires stopping production for 6-18 months, which no tier-two supplier can afford while fulfilling live contracts.

Agentic factory software that layers on top of existing CNC and robotic equipment without a full production stop is the only commercially viable entry point. All3's model targets this integration layer rather than greenfield automated manufacturing.

What could happen next?
  • Opportunity

    All3's planned expansion into Ukraine creates an unusual dual revenue model: commercial manufacturing automation in the UK, and battlefield repair and rapid-manufacture contracts in Ukraine, where the Sprint and Zig-Zag procurement tools (ID:2704) provide the contractual pathway.

Different Perspectives
European limited partners (Plural, Aviva Investors)
European limited partners (Plural, Aviva Investors)
Pan-European fund Plural led Orbital's $50m and Aviva Investors co-anchored the BBB's Lansdowne spinout fund (event ID:3505), demonstrating that Continental and UK institutional capital can fill the growth-stage tier independently, though neither has the scale to compete with US growth funds at the $100m+ band that successive ex-DeepMind rounds will eventually reach.
France (DSIT / GENCI / Institut Pasteur)
France (DSIT / GENCI / Institut Pasteur)
France signed the UK-France Strategic Biomedical Alliance on 29 May, contributing €330,000 a year to researcher mobility and linking GENCI national compute to Isambard-AI; the bilateral format suits Paris because it produces scientific access without requiring EU-framework ratification while the UK-EU science relationship remains unsettled.
US growth investors (NVentures, General Catalyst, Crosspoint Capital)

NVentures entering Orbital's cap table for the first time and General Catalyst following on in Geordie's Series A signals US growth investors treating London deeptech as a buy-side opportunity the UK market cannot contest. NVentures gains supply-chain visibility into GPU cooling; General Catalyst gains a frontier security category the RSAC prize has already validated for US enterprise.
UK Government (DSIT / British Business Bank)
UK Government (DSIT / British Business Bank)
The BBB cornerstoned Longwall at the seed floor on 27 May while DSIT signed the UK-France bilateral compute deal the same week, deploying state capital at bottom and research layers simultaneously. Neither instrument addresses the Series B middle the April 2026 mandate expansion could reach but has not.
Australian Department of Defence (AUKUS partner, Rowden Technologies)

Rowden Technologies holds active AUKUS AI for Acoustics contracts with the UK, US and Australian defence establishments. The NWF's £25m investment in Rowden on 13 May places UK sovereign capital directly into a trilateral programme Australia co-funds; from Canberra's perspective, the NWF cheque increases UK government skin-in-the-game on a programme where Australia has already committed co-development resources.
Temasek (Singapore sovereign co-investor, Isomorphic Series B)
Temasek (Singapore sovereign co-investor, Isomorphic Series B)
Temasek co-invested with the SAIU in Isomorphic's $2.1bn Series B the previous week, treating a majority Alphabet-owned company as a valid sovereign co-investment target. Fractile's round, without a UK sovereign co-investor, reads differently from Singapore's vantage: allied state capital (NATO-IF, In-Q-Tel) is now competing with Asian sovereign funds for early positions in UK deeptech.
