The landscape of European artificial intelligence hardware received a monumental boost as London-based semiconductor innovator OLIX closed a $312m (£231.8m) Series B funding round. Spearheaded by prominent global investors including Fundomo, Arm, and Hudson River Trading alongside high-profile figures such as Netflix co-founder Reed Hastings, the capital injection values the two-year-old enterprise at an impressive $3.3bn (£2.45bn). This milestone more than triples the company’s previous valuation within a span of six months, underscoring intense investor appetite for specialised silicon designed specifically to tackle the compute efficiency bottlenecks plaguing modern generative AI.
Engineering Specialised Silicon for AI Inference
Founded in 2024 by 25-year-old British entrepreneur James Dacombe, OLIX has rapidly distinguished itself by challenging the hegemony of general-purpose graphics processing units (GPUs) in large-scale machine learning deployments. While traditional hardware excels at general training workloads, inference – the process by which a trained model generates tokens in real time – presents entirely distinct computational demands. OLIX’s proprietary X-1 platform addresses this by unrolling models across custom chips linked via a high-speed optical interconnect, substituting traditional copper wiring with light to transfer data between hardware nodes with ultra-low latency.
Furthermore, the firm’s inaugural silicon offering, the DX-1 decode accelerator, deliberately departs from conventional industry dependencies. Instead of relying on High-Bandwidth Memory (HBM) or complex advanced packaging techniques that currently choke global semiconductor supply chains, the DX-1 harnesses fast on-chip SRAM. This architectural choice not only insulates OLIX from external component shortages but also delivers dramatic gains in energy efficiency and throughput for enterprise-grade generative AI deployments.

Fuelling Global Expansion and Sovereign Capability
The freshly secured capital will be deployed across several strategic fronts, most notably accelerating the commercialisation and delivery schedule of the DX-1 chip to launch customers targeted for the second half of 2027. In addition to strengthening supply chain commitments, OLIX plans to aggressively scale its world-class engineering teams across international hubs including London, Bristol, Austin, Toronto, and San Francisco.
Existing institutional backers – such as Hummingbird Ventures, Crane, Plural, Creandum, Phoenix Court, and Transition – significantly expanded their financial commitments in the round, reflecting deep conviction in the startup’s technical roadmap. Crucially, the company has also received pivotal backing from the UK government’s Sovereign AI venture fund, aligning private sector dynamism with national technological sovereignty objectives.
“The future of AI will be built on chips that power models. Countries that build chips will build leverage. OLIX is exactly the kind of ambitious company we want to back through Sovereign AI.” – Kanishka Narayan, UK AI Minister
Strategic Implications for the British Tech Ecosystem
OLIX’s meteoric rise highlights a broader structural maturation within the United Kingdom’s technology sector. Historically renowned for world-class academic research and software innovation, the UK has frequently faced capital and supply chain hurdles when scaling capital-intensive hardware ventures. OLIX’s ability to secure multi-million-pound institutional backing from global semiconductor leaders like Arm alongside tier-one venture funds signals a paradigm shift.
By anchoring advanced semiconductor research domestically while building out international engineering corridors, OLIX is positioning the UK as a formidable contender in the global AI infrastructure race. As demand for scalable, energy-efficient inference hardware intensifies across enterprise and hyperscale data centres, British silicon innovation is poised to play an indispensable role in shaping the next generation of artificial intelligence.
