The entrepreneurs behind one of Europe’s fastest billion‑dollar exits are back—and this time, they’re coming for construction.

All3, a European construction robotics startup founded in 2023 by Rodion Shishkov and Slava Bocharov, has raised $25 million in seed funding to bring its robotic building platform to market. The round was led by RTP Global, with strong backing from SuperSeed and additional participation from Begin Capital, s16vc, and VNV Global.

The founders are no strangers to scale. Shishkov and Bocharov previously co‑founded Samokat, the rapid grocery delivery service that grew to become Russia’s largest food delivery platform before being sold for $1.5 billion within five years. Now, they’re applying the same full‑stack thinking to an industry that has stubbornly resisted automation for decades.

Construction is the world’s largest sector—and one of its least productive. While manufacturing and logistics have been transformed by software and robotics, construction workflows remain fragmented, manual, and slow. All3’s response is radical: don’t optimize pieces of the system—replace the entire value chain.

Rather than offering tools to builders, All3 has rebuilt construction as a single, integrated workflow powered by AI, robotics, and automated manufacturing. The company takes responsibility for everything above the concrete foundation, from design to a move‑in‑ready building, outsourcing only the foundations themselves.

At the heart of the platform is All3 Mantis, an autonomous legged robot designed specifically for on‑site assembly. Unlike wheeled machines that struggle with uneven ground and active worksites, Mantis is built to traverse complex construction environments and handle demanding assembly tasks. The robot works alongside robotic factories that manufacture customised building components, produced to match designs generated by All3’s AI‑powered planning software.

This vertical integration gives All3 tight control over speed, cost, and precision. According to the company, its system can reduce project costs by up to 30%, shorten delivery timelines by up to 50%, and cut embodied carbon by up to 25%, without forcing developers into rigid, standardised designs.

Material choice is central to that claim. All3 builds primarily with structural timber composites, supporting both its carbon‑reduction goals and its robotic off‑site fabrication model. The approach allows buildings to be customised while still benefiting from automation—something traditional prefabrication has struggled to achieve in dense urban environments.

The company’s AI design platform has already processed over 100,000 square metres of residential projects, creating a pipeline of developments across Germany scheduled for 2026 and 2027. Germany is All3’s initial launch market, with deployments planned on active construction sites.

Competition in construction automation is growing, but fragmented. ICON focuses on concrete 3D printing for low‑rise housing. Apis Cor deploys on‑site printing at small scale. Fastbrick Robotics automates bricklaying for single‑family homes. None operates a fully integrated stack that combines AI design, robotic manufacturing, and on‑site robotic assembly for multi‑storey, multi‑family buildings, as All3 does.

Investors see that integration as the key differentiator.

“There’s huge potential for technology to improve efficiencies and project delivery in the construction sector,” said Jelmer de Jong, partner at RTP Global. “All3 brings the engineering depth and strategic focus to meaningfully drive this long‑overdue market shift”.

The fresh capital will be used primarily to expand R&D in London and Belgrade and to deploy fleets of robots on commercial projects in Germany. All3 already operates across Europe, with offices in Berlin and Zug.

After groceries, the founders are betting they can deliver something even harder—buildings, at software speed.
