The UK's Hard Tech Job Board

Isometric

Isometric operates a science-backed carbon removal registry that verifies and issues high-quality carbon credits, employing over two dozen interdisciplinary scientists and maintaining transparent, publicly auditable records for durable carbon dioxide removal projects.

Humanoid

Humanoid is a London-based robotics company creating commercially scalable humanoid robots for industrial automation. Founded by serial entrepreneur Artem Sokolov, the company has built the HMND 01 platform featuring 29 active degrees of freedom and AI-driven end-to-end reasoning. Its robots target warehouses, logistics hubs, and retail facilities through a robotics-as-a-service (RaaS) model. The company conducted a landmark trial at the Siemens Electronics Factory in Erlangen achieving 60 tote moves per hour with over 90% autonomous success rate. The team of 200+ includes alumni from Apple, Tesla, and Boston Dynamics. Preparing for a Series A round.

Anduril

Anduril Industries is a defence technology company that builds autonomous systems and AI-powered platforms for national security applications. Founded in Irvine, California by Palmer Luckey (co-founder of Oculus VR) and former Palantir executives, Anduril takes a Silicon Valley approach to defence contracting, investing its own capital in R&D rather than relying on traditional cost-plus government contracts. Its core product, Lattice OS, is an open operating system that uses sensor fusion, computer vision, and machine learning to connect autonomous hardware across air, land, sea, and space domains. The company's portfolio includes autonomous drones (Ghost, Fury, Roadrunner), counter-UAS systems, and the Ghost Shark autonomous submarine. Anduril doubled its revenue to roughly $1 billion in 2024 and is building Arsenal-1, a major autonomous weapons manufacturing facility in Ohio.

Chaos Industries

CHAOS Industries is a Los Angeles-based defence technology company that develops advanced radar, sensor, communication, and detection systems for national security applications. The company's flagship platform, Coherent Distributed Networks (CDN), delivers high-performance sensing and electronic effects across land, sea, and air domains. Its commercial radar product, Vanquish, provides early warning and tracking against drones, missiles, and aircraft. Founded by former executives of defence tech firm Epirus, CHAOS has grown rapidly in the counter-drone and critical infrastructure space. The company was valued at $4.5 billion following its latest funding round in late 2025, positioning it as one of the fastest-growing defence technology startups in the US.

Fractile

Fractile is a London-based AI chip startup developing in-memory computing processors designed to run large language model inference up to 100x faster and 10x cheaper than current GPU systems. Founded by Oxford Robotics Institute PhD graduate Walter Goodwin, the company's novel chip architecture fuses computation with memory to eliminate the data-shuttling bottleneck that limits conventional hardware. Fractile emerged from stealth in July 2024 and has since announced a £100M commitment to expand UK operations, including a new hardware engineering facility in Bristol. The team includes senior hires from NVIDIA, ARM, and Imagination Technologies.

Olix

Olix Computing is a London-based startup developing the Optical Tensor Processing Unit (OTPU), a new type of AI accelerator that uses photonics rather than traditional GPU architecture for AI inference. The company integrates photonics with an SRAM-based memory architecture, which it claims can outperform high-bandwidth memory systems in efficiency, throughput per watt, and overall cost. Originally registered as Flux Corp Ltd in March 2024, the company rebranded to Olix Computing. Founded by 25-year-old serial entrepreneur James Dacombe, who also runs brain-monitoring company CoMind, Olix has grown to over 70 employees and plans to ship its first products by 2027. Valued at over $1B.
