Company News
James Dacombe, a 25-year-old British entrepreneur, has become Europe's youngest self-made billionaire after his AI chip company Olix raised funding at a valuation exceeding $3 billion. This nearly tripled the company's $1 billion valuation from February, when it secured $220 million. Dacombe, who began programming at 13 without formal training, left school as a teenager with support from the Thiel Fellowship. He founded CoMind in 2017-2018, developing non-invasive brain monitoring technology. The startup raised $60 million in 2025, bringing total funding to $102.5 million. Launched in 2024, Olix develops specialised chips for AI inference. Investors include Arm, Netflix co-founder Reed Hastings, and the British Sovereign AI Fund. Commercial chip shipments are expected by late 2027.
Today, we are announcing our $300M Series B raise, led by Andreessen Horowitz and joined by Sapphire Ventures, Menlo Ventures, 645 Ventures, Arm, Eclipse, Emergence, Factory, Hudson River Trading, M12, OnePrime Capital, Prosperity7, QuantumLight, Samsung Ventures, Tiger Global Management, Triatomic, Wing Ventures, and XTX Markets.
London-based AI chip developer Olix has raised $312 million in a funding round led by New York investment firm Fundomo, with participation from Arm, Hudson River Trading, and Netflix co-founder Reed Hastings. The round values the company at $3.3 billion, up from just over $1 billion in February. Founded in 2024 by James Dacombe, Olix plans to tape out its chips later this year and deliver first products to customers in 2025. The company employs over 140 staff across London, Bristol, Toronto, and Austin. Olix differentiates itself with a photonic interconnect that uses lasers to move data between chip clusters with greater energy efficiency. The company also avoids scarce semiconductor components and uses proprietary AI tools to accelerate development, including work on its compiler. Matt Briers, former CFO at fintech Wise, joins as chief financial officer.
Gray Swan, an AI security company born from Carnegie Mellon University research, has raised $40 million in a Series A round co-led by Wing Venture Capital and Madrona. Obvious Ventures, Snowflake Ventures, Hudson River Trading, Samsung Next and Magarac Venture Partners also participated. The company, founded by Matt Fredrikson and Zico Kolter, provides security platforms for AI models and agents. Gray Swan is cited in 11 recent frontier model system cards from Anthropic, OpenAI and Meta, and its benchmarks are embedded in safety evaluation processes for advanced AI models. The platform includes three components: Cygnal for real-time AI protection, Shade for automated adversarial testing, and Arena, a global red-teaming network with over 15,000 researchers. Gray Swan works with over 20 customers and has partnered with Snowflake to integrate its security capabilities.
AI networking startup Eridu has emerged from stealth with a $200 million Series A round led by Socratic Partners, John Doerr, Matter Venture Partners and others, bringing total funding to $230 million. The oversubscribed round values the company comparably to other large Series A deals, though CEO Drew Perkins declined to confirm unicorn status. Founded in 2024 by networking veterans Drew Perkins and Omar Hassen, Eridu is developing new silicon and systems designed specifically for AI data centres. The company aims to replace traditional tiered optical connections with on-chip communications, reducing latency and power consumption whilst improving reliability. Perkins previously co-founded Lightera Networks, Infinera and Gainspeed, companies that collectively generated over $2.7 billion in exits. Other investors include Hudson River Trading, Capricorn Investment Group, TSMC's VentureTech Alliance and MediaTek.
