All3 raised a $25m seed led by RTP Global on Wednesday 29 April to build agentic factories for defence, robotics and aerospace clients, with planned expansion into France, Germany and Ukraine following the round.

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
Australian Department of Defence (AUKUS AI for Acoustics partner)
Australian Department of Defence (AUKUS AI for Acoustics partner)
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 brings UK sovereign capital directly into a trilateral programme, which from Canberra's perspective places additional UK government skin-in-the-game on a programme Australia co-funds and co-develops.
Sofinnova Partners (European VC co-investor in Cytospire Series A)
Sofinnova Partners (European VC co-investor in Cytospire Series A)
Sofinnova participated alongside the BBB in Cytospire's oversubscribed £61m Series A on 5 May, demonstrating that the BBB's expanded direct mandate is attracting established European specialist biotech funds rather than replacing them. European VCs see the BBB's cornerstone position as a signal reducing UK biotech execution risk rather than crowding out private capital.
Temasek (Singapore sovereign co-investor in Isomorphic Series B)
Temasek (Singapore sovereign co-investor in Isomorphic Series B)
Singapore's Temasek co-invested alongside the UK's SAIU in Isomorphic's $2.1bn round, treating the same Alphabet-majority company as an acceptable sovereign co-investment target. Temasek's participation normalises the structure: multiple sovereign wealth funds backed the same round, strengthening the precedent that UK-headquartered Alphabet subsidiaries qualify for state investment.
Alphabet / Google (majority Isomorphic shareholder, Mountain View)
Alphabet / Google (majority Isomorphic shareholder, Mountain View)
Alphabet co-invested via GV and CapitalG in the same Isomorphic Series B round that received UK sovereign backing, placing US corporate capital and UK public capital in the same syndicate without any governance asymmetry. SAIU's minority stake validates Isomorphic's strategic value without constraining Alphabet's control over IP, geography, or exit decisions.
DSIT / Liz Kendall, Secretary of State for Science

DSIT framed the Isomorphic investment as backing a British-founded and headquartered company advancing UK AI capability, and described the nine-day sovereign deployment sprint as evidence the government's industrial strategy is operational. The department has not addressed the ownership question, the absence of eligibility criteria, or the pace-versus-doctrine tension in the BBB mandate.

Five sub-£50m rounds closed in nine days with zero VCT-backed angel networks on any cap table, confirming the post-cut investor map is forming fast in the £4m–£40m band. The gap is structural: 36.7% of university spinouts raised below £500,000 in 2025, a tier neither the SAIU nor the BBB direct mandate touches.
