What Optalysys does

Optalysys is a UK-based silicon photonics computing company founded in 2013 in Leeds, developing hardware that performs computation using light rather than electricity. Its core architecture integrates data movement and processing on a single chip, enabling a "compute-in-transit" approach that executes computation directly within the optical transport layer at communication line speeds (hundreds of gigabits to terabits per second). The company's product portfolio includes the LightLocker Node (a dedicated hardware solution for encrypted blockchain applications using Fully Homomorphic Encryption), the Photonic Compute Core (a programmable optical compute layer), Silicon Photonic Chips, and FPGA-based encrypted compute servers. Optalysys targets financial services, defense and government, AI data centers, blockchain/Web3, and healthcare verticals, with a particular focus on accelerating FHE and post-quantum cryptography workloads that overwhelm conventional electronic processors. The company claims 10–50x better energy efficiency per bit than electronic alternatives and latency reductions from microseconds to nanoseconds.

The company operates an enterprise field sales motion, selling photonic chip modules and systems directly to large organizations through a sales-led approach. Revenue mechanics consist of hardware sales and potential managed encrypted compute services, though the company is currently pre-revenue with its first commercial product launched in 2025 and initial shipments underway to a key US partner in 2026. Optalysys maintains headquarters in Leeds and an engineering site in Bristol in the UK, and has established a US commercial base in Santa Clara, California, led by newly appointed CEO Chris Walker (formerly Corporate VP at Intel and CEO of Untether AI, which was acquired by AMD). Total disclosed funding exceeds £44 million, with backing from Northern Gritstone, imec.xpand, Lingotto Horizon, and the UK government's National Security Strategic Investment Fund.

Direct peers

• Lightmatter: Lightmatter develops silicon photonic AI accelerators and interconnects, most directly comparable to Optalysys in using light-based compute for AI workloads. Both target data center customers with photonic compute fabric and have raised significant venture capital.
• Celestial AI: Celestial AI builds a photonic interconnect fabric (Photonic Fabric) that integrates memory and compute — a directly comparable architectural vision to Optalysys's compute-in-transit approach. Both target hyperscalers with optical-based data movement/processing.
• Lightelligence: Lightelligence develops photonic AI processors for data center inference and HPC workloads. Same photonic compute category as Optalysys, addressing similar enterprise and data center customers with optical processing units.
• Luminous Computing: Luminous Computing is building photonic AI supercomputers using silicon photonics for large-scale model training/inference. Closely comparable technology stack and target market to Optalysys.

Broad incumbents

• Intel (Silicon Photonics & Encrypted Computing): Intel has both silicon photonics roadmaps (optical compute interconnect, integrated photonics research) and the Encrypted Computing program founded by Ro Cammarota (now an Optalysys advisor). Intel is both a potential competitor and a giant incumbent whose photonics efforts dwarf Optalysys's resources.
• AMD: AMD acquired Untether AI (where Optalysys's new CEO Chris Walker was CEO) and Xilinx (FPGAs used in encrypted compute). A potential acquirer and competitor with broad AI compute, FPGA, and adaptive compute portfolios overlapping Optalysys's photonic and FPGA-based offerings.
• NVIDIA: NVIDIA dominates AI training/inference compute via GPUs and is extending into networking (NVLink, Spectrum-X) and DPUs (BlueField) — the same data movement/processing layer Optalysys targets photonically. As the incumbent AI infrastructure standard, NVIDIA represents the most formidable long-term competitive threat.

Emerging players

• Zama: Zama develops FHE software/tooling and is an Optalysys partner. Comparable in FHE focus but software-only — Optalysys provides the photonic hardware layer on top of which Zama's tools run. Both pursue always-encrypted computation.
• Inpher: Inpher builds privacy-preserving computation (XOR Platform) including FHE and secure multiparty computation. Directly comparable to Optalysys on the encrypted compute use case; Dr. Dimitar Jetchev (Optalysys advisor) was formerly Inpher's CTO and co-founder.
• Duality Technologies: Duality Technologies provides FHE-based secure data collaboration tools for enterprises. Comparable in FHE/secure compute focus; Optalysys would compete as a hardware acceleration layer beneath Duality's software.
