Ant Mishuan (蚂蚁密算)
Category: AI Safety
Ant Group's confidential-computing subsidiary building full-stack privacy-preserving computation technology (FHE, MPC, TEE) and open-sourcing agent-safety frameworks like HOP. Ant Mishuan (蚂蚁密算) was founded in 2024. The company is led by Wang Lei (王磊). Based in Hangzhou, Zhejiang, China. Latest round: Bootstrapped. Key investors include Ant Group (100% parent-company ownership, wholly-owned subsidiary, not independently VC-funded).

Value proposition
Provides 'confidential computing' (密态计算) infrastructure — combining cryptography, trusted hardware, and system security — to enable secure, trustworthy data circulation and AI computation without exposing raw data, including safety guardrails for LLM/agent applications.
Products and solutions
MPU H1 (fully homomorphic encryption acceleration chip, claims 10,000x+ speedup over CPU for FHE), SecretFlow (隐语) privacy computation framework, HOP (High-Order Program) framework / HOP 3.0 'Agent Native Language' for safe LLM agent execution, 密态可信数据空间 (Confidential Trusted Data Space), 密算一体机 (confidential computing all-in-one appliance), 密态大模型计算平台 (confidential LLM computing platform).
Unique value
End-to-end 'confidential computing' stack spanning custom silicon (FHE accelerator chip), OS-level security, and application frameworks — positioned as full-stack rather than single-technique (pure MPC or pure HE) privacy computing provider, with proprietary hardware acceleration claimed to lead global competitors by 10x.
Target customer
Financial institutions, healthcare organizations, government/state-owned enterprises, and enterprises needing secure data-sharing and trustworthy AI infrastructure.
Industries served
Finance, Healthcare, Government/Public Sector, State-owned enterprises, AI/LLM infrastructure
Technology advantage
Proprietary MPU H1 fully homomorphic encryption (FHE) acceleration chip; supports BFV/BGV/CKKS/TFHE algorithms; full-stack integration of cryptography + trusted hardware + system security; HOP framework for verifiable/safe agentic LLM task execution with reported ~91.7% success rate on irreversible-action safety gating; over 1,700 patent applications in privacy computing (global #1), leads 117 global standards.
How they differentiate
Full-stack approach (custom FHE chip + OS + framework) vs. competitors who typically focus on either MPC or pure software privacy computing; backed by Ant Group's data/AI ecosystem scale; open-sources core frameworks (SecretFlow, HOP) to build developer ecosystem.
Main competitors
华控清交 (TsingJ, Tsinghua-affiliated privacy computing firm, ~6.5% market share), 富数科技 (Fudata), 蓝象智联 (Lanxiang, ~5.2% market share)
Key partnerships
Parent company Ant Group (100% owner), part of Ant Group's SecretFlow (隐语) open-source ecosystem, recognized with World Internet Conference Outstanding Contribution Award, serves large state-owned enterprises for trusted data space use cases.
Major milestones
2016: Ant Group begins privacy computation R&D. May 31, 2024: Zhejiang Ant Mishuan Technology Co., Ltd. formally incorporated as independently-operated subsidiary. April 2025: released 密态可信数据空间 (Confidential Trusted Data Space) product. 2025 WAIC (World Artificial Intelligence Conference): released open-source HOP framework. 2026: released HOP 3.0 'Agent Native Language' framework, open-sourced, reporting ~91.7% task-safety success rate isolating irreversible agent actions. Received World Internet Conference Outstanding Contribution Award (Jan 2026).
Growth metrics
Ant Group's overall privacy-computing platform business reported to serve 'over 10 million' (千万级) users per company PR; registered capital RMB 10M at incorporation (May 2024).
Market positioning
Market leader in China's privacy computing platform space — cited at 35.3%-36.9% market share (as Ant Group/蚂蚁数科 entity) per IDC industry reports (2026), ahead of 华控清交 (~6.5%) and 蓝象智联 (~5.2%).
Geographic focus
China (primary); positions FHE chip performance claims against unnamed international competitors.
Patents and IP
1,700+ patent applications in privacy computing (claimed global #1 by count); leads/participates in 117 global privacy-computing standards (most led by any single entity per company claims); open-sourced HOP 3.0 framework.
