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
Beauhurst / UK startup data analysts
Beauhurst / UK startup data analysts
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.
BVCA / UK VC industry body
BVCA / UK VC industry body
The post-VCT investor map has sorted into three non-overlapping pools with no ladder between them; the £500k–£2m band VCTs historically anchored now has no obvious replacement. Beauhurst data showing 36.7% of spinout fundraisings below £500,000 in 2025 suggests the pipeline narrows at the base, compounding within three to five years.

The EC approved €211m of Italian state aid for CamGraPhIC in the same week Britain named five AI hardware startups without specifying a capital instrument. Brussels' willingness to write an industrial-scale factory cheque contrasts with London's pre-announcement of a plan whose mechanism remains unspecified until June.
Sequoia Capital / Lightspeed Venture Partners

Sequoia and Lightspeed co-led Ineffable's $1.1bn seed on research credibility alone, with no product and no revenue; the SAIU minority stake followed their commitment. For US growth funds, the sovereign validator reduces political risk and accelerates LP approval for non-revenue European bets.

DSIT withheld the SAIU cheque size as commercially sensitive, framing the unit's second equity investment as proof sovereign capital can mobilise private-led syndicates. Kendall's RUSI address positioned the SAIU and ARIA as instruments of sovereign control, raising the political commitment attached to the June AI Hardware Plan.

At Series B and above, the UK ecosystem is in a strong position: $7.8bn in Q1 is 41% of European VC, seven unicorns were minted in three months, and London remains the deepest late-stage capital market outside the United States.
