What AOMEI does

AOMEI Tech Co., Ltd. is a privately-held software company founded in 2009 and headquartered in Hong Kong that develops disk partition management and data protection utilities for Windows and macOS environments. Its flagship product, AOMEI Partition Assistant, is offered in five editions (Standard/free, Professional, Server, Unlimited, Technician) and enables resizing, moving, merging, splitting, and hiding partitions without data loss, OS migration from HDD to SSD without reinstallation, MBR/GPT and basic/dynamic disk conversion, sector-level disk cloning, secure data wiping, file shredding, and BitLocker-based partition encryption. The product line has been extended with PartitionAssistant Recovery (data recovery across Free/Professional/Technician tiers), PartitionAssistant Cleanup (PC optimization), and PartitionAssistant NTFS for Mac (cross-platform NTFS access). The core technology rests on proprietary lossless partitioning algorithms with a claimed 100% success rate in resizing operations and sector-level data protection during cloning.

The company operates with a 27-person team and a freemium business model in which the Standard edition is free for personal and commercial use while paid editions are sold as one-time perpetual licenses. Its customer base of 80M+ users spans 180+ countries and is segmented across individual/home users, SMBs running Windows Server, enterprise IT departments, and managed service providers and IT technicians offering billable services. Recovery Professional and Technician are the only subscription-priced products, indicating limited exposure to recurring revenue.

Go-to-market combines product-led growth (free download acquisition via diskpart.com) with a three-tier partner channel comprising a 6,000+ global reseller network, affiliate programs through CJ Affiliate, Partnerize, and Avangate, and OEM white-label partnerships for hardware and software vendors. Distribution is reinforced by content marketing, community engagement at community.diskpart.com, and earned media from publications including Techradar, Softpedia, Download.com, and Lifehacker. The company is independently owned with no disclosed external funding rounds, parent company, or public listing.

Expansion highlights5 records

Regional players

• Clonezilla: Clonezilla is an open-source disk cloning and imaging tool that competes with AOMEI's cloning and migration features. While not a freemium commercial product, it represents a free alternative that pressures AOMEI's paid cloning use cases, particularly among technical users.

Emerging players

• Disk Drill (Cleverfiles): Disk Drill is a cross-platform data recovery tool competing with AOMEI's Recovery product. While Disk Drill emphasizes macOS/Windows parity, it overlaps meaningfully in Windows data recovery, particularly for individual users and small businesses.
• Stellar Data Recovery: Stellar specializes in data recovery software that directly competes with AOMEI's PartitionAssistant Recovery line. Both target Windows users needing file and partition recovery, with similar freemium tiering and professional editions.

Direct peers

• EaseUS: EaseUS is the most direct competitor to AOMEI, offering EaseUS Partition Master with a comparable freemium-to-paid tier structure (Free, Professional, Server, Technician). Both target Windows users with disk partition management, cloning, and recovery capabilities.
• Paragon Software Group: Paragon Hard Disk Manager is an enterprise-grade disk partitioning and backup suite directly comparable to AOMEI's Server and Unlimited editions. Both serve the SMB/enterprise Windows partition management segment with cloning and migration capabilities.
• Macrorit: Macrorit Partition Expert is a smaller but direct competitor in the Windows partition management space, offering free and paid editions targeting individual and enterprise users with similar resize, clone, and migration features.
• MiniTool Software: MiniTool Partition Wizard is a category-leading Windows partition manager with a similar freemium model targeting home users, enterprises, and technicians. Their product lineup and pricing structure closely mirror AOMEI's edition strategy.

Broad incumbents

• IObit: IObit is a broader PC utility suite vendor offering system optimization, driver updaters, and disk tools that compete with AOMEI's Cleanup product line. Both target Windows users seeking comprehensive PC maintenance with freemium models.
• Piriform (CCleaner): CCleaner is the dominant Windows PC cleanup and optimization tool, now part of Avast/Norton. Its cleanup functionality directly competes with AOMEI's PartitionAssistant Cleanup product for the same end-user base.
• Acronis: Acronis is a much larger incumbent in backup, recovery, and disk management for SMB/enterprise, offering True Image and Cyber Protect that overlap with AOMEI's Partition Assistant and Recovery lines but as part of a broader cybersecurity/backup platform.
