Overview
- Olix closed the $312 million Series B on Monday, expanding its post-money valuation to $3.3 billion and making the round one of Europe’s largest semiconductor VC deals.
- The company says the new funds will complete its first decode accelerator, DX-1, and scale the X-1 platform with initial customer access targeted for the second half of 2027.
- Olix’s X-1 architecture disaggregates model inference across specialised chips linked by an optical interconnect that moves data with light rather than copper to avoid reliance on high-bandwidth memory (HBM).
- The round attracted strategic and high-profile backers including Arm, Fundomo, Hudson River Trading, Netflix cofounder Reed Hastings, and the UK Sovereign AI fund and coincided with hires and board additions such as Nick McKeown and CFO Matt Briers.
- The company remains pre-revenue and faces two near-term tests that matter for customers and investors: proving DX-1’s real-world throughput and power efficiency and achieving high-yield photonic chip manufacturing at scale, outcomes that will shape Europe’s ability to diversify AI compute supply chains.
