KEY TAKEAWAYS
- The $25 million round was led by RTP Global, with participation from SuperSeed, Begin Capital, s16vc, and VNV Global.
- All3’s Mantis robot is a four-legged autonomous construction robot carrying over 100 kilograms and four
- A fleet of Mantis robots can complete a seven-storey building in three months faster
- All3 has processed over 100,000 square metres of residential projects through its AI design platform
All3, the London-founded construction robotics company, announced a $25 million seed round on 29 April 2026, one of the largest European deep tech seed raises this year. It aims to scale its AI and robotics platform across major housing markets, a new tech trend in the UK.
The round was led by RTP Global, whose portfolio includes Datadog and Delivery Hero, with backing from SuperSeed, Begin Capital, s16vc, and VNV Global. The capital will fund R&D in London and Belgrade and deploy All3’s first fleet of commercial robots on active construction sites in Germany later this year.
What All3 Has Actually Built
Unlike construction technology companies that automate one part of the building process, All3 has rebuilt the entire workflow from the ground up.
As The Next Web confirmed, the platform integrates three components into a single connected system:
- An AI-powered design platform that translates a site address or brief into a fully compliant building design
- Compact robotic factories that fabricate custom structural timber composite components to 0.2 millimetre precision
- Mantis, an autonomous legged robot that assembles those components on-site
Mantis uses plug-and-play connectors to complete typical structural elements in under a minute, tasks that take up to 30 minutes manually.
This advancement in physical intelligence mirrors the broader momentum in the capital, recently highlighted when a just months old AI startup, Ineffable Intelligence, raised £815 million, further cementing London’s status as a global AI hub.
The result, per All3’s own figures, is a 50 per cent reduction in project timelines, a 30 per cent reduction in costs, and 25 per cent less embodied carbon compared to conventional concrete and steel builds.
The Founding Team and the Problem They Are Solving
As Startup Rise confirmed, All3 was founded in 2023 by Rodion Shishkov and Slava Bocharov. This is the duo who previously co-founded Samokat, Russia’s largest rapid grocery delivery platform, which they sold for $1.5 billion within five years of launch.
The founders are applying the same systems-level thinking they used to scale food logistics to a sector that has seen virtually no productivity improvement in 50 years. To support high-growth firms like this, new financial frameworks are emerging in the UK.
Construction is a $6.7 trillion global industry, the largest single sector in the world economy, where a building project in 2026 involves broadly the same manual handoffs and site labour as one completed in 1976.
Shishkov said in a statement that construction remains the largest global sector yet to undergo a productivity revolution, representing a trillion-dollar opportunity.
He added that the funding will support scaling the deployment of the technology with a clear mission to help address the housing crisis once and for all.
Germany First, Europe Next
All3 has selected Germany as its first commercial launch market, a deliberate choice.
As Tech Funding News confirmed, Germany faces an acute housing shortage of about 700,000 homes, driven by years of under-building, high construction costs, and a chronic shortage of skilled tradespeople.
Dense urban areas are the hardest case for traditional prefabrication systems, which rely on standardised designs that cannot adapt to irregular city plots where housing demand is highest. All3’s platform is specifically engineered for exactly those conditions.
The company operates across Europe with its R&D backbone in the UK and Serbia, benefiting from a landscape bolstered by the newly launched £500M Sovereign AI Unit focused on national technological growth.
Jelmer de Jong, RTP Global Partner and newly appointed All3 board member, said Europe needs its own physical AI champions. He added that All3 brings the engineering depth and strategic focus needed to drive this long-overdue market shift.
