Highrise AI Appoints Former Israeli Defense Forces Sigma R&D Chief as CTO, Signaling Strategic AI Infrastructure Push

With institutional interest in AI infrastructure surging and geopolitical concerns driving demand for secure, high-performance computing environments, Highrise AI, a subsidiary of Hut 8 Corp, has made a strategic move by appointing Mark Mendelman—former head of artificial intelligence and R&D at the Israeli Defense Forces’ elite Sigma unit—as its new Chief Technology Officer.

The appointment, announced July 31 via PR Newswire, reflects growing industry urgency to develop sovereign, secure AI infrastructure solutions that can serve critical sectors—from defense to healthcare and government.

Mendelman’s background in military-grade AI architecture places Highrise AI in a unique position as the race intensifies to provide bare-metal compute environments that can host sensitive, large-scale workloads outside of the major cloud players.


AI Security Meets Infrastructure Innovation

Highrise AI’s platform is focused on secure, high‑performance computing designed to support the compute demands of large language models (LLMs), computer vision, and generative AI systems. Their infrastructure differentiates itself by offering dedicated, isolated compute environments—unlike shared public cloud models that pose potential security risks for sensitive data.

Mendelman’s appointment is not symbolic—it’s strategic. Having overseen classified AI programs within Israel’s most advanced military tech branch, his role will likely center on strengthening Highrise’s AI workload orchestration, sovereign data compliance, and zero-trust infrastructure layers.

“Mark’s experience leading some of the world’s most advanced defense AI programs gives us an immediate edge in delivering AI infrastructure that meets the real-world needs of regulated, mission-critical clients,” said Asher Genoot, President of Hut 8.

This aligns with Highrise’s recent expansion strategy following its 2023 merger between Hut 8 and US Data Mining Group (US Bitcoin Corp), which created one of North America’s largest infrastructure-first crypto and compute firms.


Why This Matters for Investors

The generative AI gold rush isn’t just about algorithms—it’s about compute. A Goldman Sachs report from April 2025 estimates that global capital expenditure in AI data centers will exceed $3 trillion by 2028. Yet the majority of institutional demand remains unmet due to concerns over data security, operational control, and jurisdictional limitations in public cloud offerings.

Highrise AI is positioning itself as a trusted alternative—especially for clients in defense, aerospace, financial services, and government—who require localized, high-assurance AI compute environments.

The addition of Mendelman could serve as a catalyst to attract defense contracts, enterprise partnerships, or even federal AI infrastructure projects, especially in light of recent geopolitical developments that emphasize national AI capability.

“The appointment sends a clear signal to investors: Highrise is serious about becoming a critical infrastructure provider in the AI arms race,” said Emily Cheng, tech analyst at Northern Strategies Research.


Future Trends to Watch

  • Defense-Tech Convergence: With former military AI talent now joining private infrastructure providers, expect growing overlap between government funding and commercial AI projects.
  • Bare-Metal AI Demand: As LLMs grow in size and sensitivity, companies are shifting toward non-cloud-native solutions that offer full control over hardware, latency, and data sovereignty.
  • Infrastructure as Alpha: Investors are increasingly focusing on picks-and-shovels players—those who provide compute, semiconductors, and secure environments over flashy AI applications.
  • Sovereign AI Acceleration: The appointment may also align with Canada’s and the U.S.’s evolving national AI strategies, including efforts to de-risk reliance on Chinese or foreign-controlled infrastructure.

Key Investment Insight

Hut 8’s Highrise AI unit may be under the radar now, but this move signals a potential breakout trajectory in the AI infrastructure sector. The strategic hiring of a defense-aligned CTO positions Highrise to compete in the growing space for secure AI infrastructure, a niche with rising demand and limited competition.

Investors looking for long-term exposure to AI without chasing overvalued software stocks should consider infrastructure players like Hut 8/Highrise AI as asymmetric bets tied to real-world enterprise and government use cases.
