All3 raises $25M seed for construction robotics
All3 Construction has raised $25 million in seed funding for construction robotics.
All3, a London-based startup building an end-to-end robotics platform for construction, raised a $25 million seed round on April 29. The round was led by RTP Global, with participation from SuperSeed, Begin Capital, s16vc and VNV Global. Funds go toward R&D in London and Belgrade and deploying an initial robot fleet on commercial construction sites in Germany, the company's first launch market.
All3 is rebuilding the above-ground construction value chain into one integrated pipeline: AI-generated design, robotic factories that fabricate timber composite components, and Mantis, an autonomous legged robot for on-site assembly. Mantis carries more than 100 kilograms, reaches up to four meters, and a fleet can complete a seven-story 5,000-square-meter building in around three months. The company has already processed more than 100,000 square meters of residential projects through its design software.
Co-founders Rodion Shishkov and Slava Bocharov previously built Samokat, Russia's largest rapid grocery delivery business, which sold for $1.5 billion. Shishkov also founded TRA Robotics, later acquired by Arrival. RTP Global partner Jelmer de Jong joins the board.
Construction spends less than 1% of revenue on R&D versus 4.5% in automotive, and labour productivity has barely moved in 75 years.
