Olix Raises $312M at $3.3B Valuation: Photonic AI Chip Startup Takes on Nvidia

Olix has now raised over $530 million in total funding, following a $220 million Series A in February 2026 that valued the company at approximately $1 billion .

Key Executive Appointments

Alongside the funding, Olix made two high-profile hires:

• Matt Briers, the former CFO of Wise who led its public listing, joined Olix as chief financial officer .
• Professor Nick McKeown, a Stanford computer science professor, co-inventor of software-defined networking, and a defining figure in modern networking, was appointed to the board of directors .

Technology: Optical Chips Built for AI Inference

Olix is not building another GPU. The company's platform is fundamentally different from Nvidia's approach, targeting the specific bottleneck it believes is holding back AI inference: memory bandwidth .

Olix's architecture is built around two key components:

• X-1 optical digital processor platform: Rather than using traditional GPUs with high-bandwidth memory (HBM), the X-1 platform "unrolls" a model across many specialized chips connected by an optical interconnect network . This "slow-and-wide" optical approach aims to solve the memory-bandwidth constraints that limit Nvidia-based systems .
• DX-1 decode accelerator: A photonic inference chip that ditches HBM entirely, targeting the inference market with a light-based processing approach . The company calls its chips Optical Tensor Processing Units (OTPUs) .

Olix says its approach could fundamentally change how AI models are deployed, especially for inference workloads where power efficiency and memory bandwidth are critical.

Product Timeline and Use of Funds

Olix plans to deliver its first products to customers in 2027, with first customer access targeted for the second half of the year . The company will use Series B proceeds to:

• Complete the DX-1 decode accelerator
• Expand the X-1 photonic platform
• Fund manufacturing and supply chain commitments to scale production

Olix is also expanding its workforce across London, Bristol, Austin, Toronto, and San Francisco, hiring for teams working on silicon, photonics, compilers, and systems .

Why This Matters

Olix's rapid valuation growth — from $1 billion to $3.3 billion in six months — reflects intense investor appetite for alternatives to Nvidia's near-monopoly in AI chips. The company's photonic approach represents a bet that the future of AI inference will be defined not by raw compute throughput, but by how efficiently data moves between processors .

However, it's worth noting that Olix's performance claims are company-reported and not yet validated in production hardware . The first customer deliveries in 2027 will be a critical test of whether photonic computing can actually compete with established GPU architectures in real-world deployments.
