Niobium Microsystems

What Niobium Microsystems does

Niobium Microsystems is a Dayton, Ohio-based semiconductor and cloud infrastructure company spun out of Galois Inc. that builds hardware and software for fully homomorphic encryption (FHE). Its core technology enables computation directly on encrypted data without decryption, which the company positions as addressing the fundamental security gap in cloud computing where data typically must be decrypted before processing. The company's product stack is anchored by The Fog, the first Infrastructure-as-a-Service platform purpose-built for FHE, which is powered by a proprietary mistic Core processor architecture and complemented by a custom FHE Accelerator ASIC. The first-generation FHE chip completed tape-out at Global Foundries' US 12nm low power fab, and a second-generation ASIC is being manufactured on Samsung Foundry's 8nm Low Power Ultimate process through a design partnership with SEMIFIVE valued at approximately $6.86 million.

The company monetizes through two distinct revenue streams: usage-based access to The Fog encrypted cloud platform, and hardware sales of its FHE accelerator ASIC targeting hyperscalers and AI infrastructure providers. Pricing is not publicly disclosed, and The Fog is currently in private beta with broader public availability targeted for late Q2 2026, with a Developer Partner Program opened in June 2026 providing SDKs, pre-built FHE applications, and dedicated accelerator access. Target customer segments are primarily enterprise buyers in life sciences and healthcare, financial services, security and defense, and AI infrastructure, with secondary interest in blockchain and federated learning applications.

Niobium has raised approximately $33 million across funding rounds from 2021 to 2025, with the most recent $23 million+ round led by Blockchange Ventures in December 2025. The company operates with 51-100 employees and has assembled senior leadership including a CEO (Kevin Yoder), Chief Scientist (Luke Duncan), and recently hired VP of Product from Groq and VP of Finance from Celestial AI. Its go-to-market combines a product-led developer adoption motion with enterprise field sales targeting hyperscaler and AI infrastructure accounts via its SEMIFIVE/Samsung Foundry manufacturing channel.

Core offering

Niobium Microsystems builds hardware-accelerated fully homomorphic encryption (FHE) silicon and The Fog, an Infrastructure-as-a-Service cloud platform purpose-built for computing on encrypted data without ever decrypting it. The company sells custom FHE accelerator ASICs manufactured at Samsung Foundry's 8nm process and powers The Fog with its proprietary mistic Core processor, claiming up to 25x faster FHE performance than GPUs. Target customers include hyperscalers, AI infrastructure providers, financial institutions, life sciences firms, blockchain developers, and defense organizations that need provable, quantum-resilient privacy during computation.

Product overview

Niobium Microsystems offers a platform-plus-accelerator architecture centered on The Fog (Niobium FOG™), the first Infrastructure-as-a-Service platform purpose-built for fully homomorphic encryption. The platform is powered by the proprietary mistic Core processor and complemented by a production-grade FHE Accelerator ASIC (manufactured via SEMIFIVE/Samsung Foundry at 8nm) that delivers up to 25x faster FHE performance than GPUs. Pre-built FHE applications and an SDK enable developer access, while a partnership with CryptoLab extends the platform's privacy-preserving AI capabilities to real-time encrypted GenAI and LLM inferencing.
