Niobium Microsystems is a technology company.
Niobium Microsystems delivers purpose-built hardware accelerators for fully homomorphic encryption (FHE). This custom PCIe card enables direct computation on encrypted data, eliminating decryption and providing a strong mathematical privacy guarantee. The technology addresses critical data security challenges maintaining confidentiality throughout active processing.
Rob Wiltbank founded Niobium Microsystems to address the urgent need for advanced data privacy. His insight recognized vulnerabilities when traditional encryption requires data decryption for computation. Wiltbank conceived specialized hardware to process sensitive information, preserving absolute confidentiality, leading to their FHE accelerator.
Niobium Microsystems’ products serve organizations managing highly sensitive information across sectors requiring stringent data privacy. Their technology facilitates secure collection, processing, and distribution of critical data without exposure. The company envisions establishing a new global standard for data security, fostering trust by safeguarding information during all operational stages.
Niobium Microsystems has raised $29.0M across 2 funding rounds.

Niobium Microsystems is a technology company specializing in Zero Trust Computing solutions, particularly the industry's fastest fully homomorphic encryption (FHE) hardware accelerators. These PCIe cards accelerate FHE software by orders of magnitude, enabling secure data processing where data remains encrypted during computation, serving enterprises in cloud computing, fraud detection, medical research, and high-performance computing[1][4]. The company targets organizations needing mathematically guaranteed privacy for machine learning and statistical analysis while ensuring regulatory compliance, with scalable accelerators compatible from battery-operated devices to large systems, including neuromorphic processing for real-time sensor data and autonomous decision-making[2][4].
Spun out from Galois in 2021, Niobium retains exclusive access to advanced FHE technologies and is headquartered in Dayton, Ohio, with offices in Columbus, Ohio, Portland, Oregon, and San Francisco[1]. Their hardware supports all major FHE schemes, integrates easily into servers via low-power PCIe cards, and demonstrates strong growth momentum through SBIR funding for innovations like radiation-tolerant designs and heterogeneous SoC integration[1][2].
Niobium Microsystems emerged as a spinout from Galois, a leading cryptography and privacy technology firm, in 2021. This transition provided Niobium with a strategic partnership, granting exclusive access to Galois's expertise in FHE, compiler optimization, and advanced privacy technologies[1]. The founding team leveraged Galois's deep background in secure computing to focus on practical hardware acceleration for FHE, addressing the performance bottlenecks that previously limited its adoption[1][4].
Early traction came through government-funded R&D, including SBIR Phase I and II efforts with NASA, where Niobium prototyped scalable neuromorphic accelerators for autonomous systems, radiation-hardened designs using MRAM, and integration with RISC-V/ARM processors[2]. These pivotal moments validated their architecture's versatility across commercial, defense, and space applications, setting the stage for their first purpose-built FHE PCIe accelerator[2][4].
Niobium stands out in secure computing through hardware tailored for FHE and related workloads:
Niobium rides the Zero Trust and privacy-preserving computation wave, fueled by rising data breaches, AI/ML demands on sensitive data, and regulations like GDPR/HIPAA. FHE's timing is critical as cloud/edge computing explodes, but software limitations (slow performance) hinder adoption—Niobium's hardware unlocks real-world use in fraud detection, genomics, and secure multi-party ML[1][4].
Market forces favor them: surging edge AI, autonomous systems (e.g., NASA/space), and defense needs for radiation-hardened tech align with their scalable, neuromorphic-capable designs[2]. They influence the ecosystem by pioneering FHE hardware standards, partnering with Galois for IP edge, and enabling startups/enterprises to build privacy-native apps, potentially accelerating Zero Trust from niche to mainstream[1][3].
Niobium is poised to dominate FHE hardware as privacy regulations tighten and AI data volumes grow, with next steps likely including commercial PCIe card launches, expanded SoC integrations for edge/defense, and broader neuromorphic/radiation-hardened products via SBIR scaling[2][4]. Trends like sovereign AI, secure federated learning, and space autonomy will propel them, evolving their role from accelerator pioneer to foundational secure compute provider. This positions Niobium to transform Zero Trust from theory to practical reality, unlocking data's full value securely[1].
