Company profile
researched Aug 2026X1 develops software that lets people and organizations find and act on information in place, wherever it resides, for legal, compliance, governance, investigatory and productivity purposes. The company markets two product lines: the X1 Enterprise Platform, aimed at eDiscovery and information governance teams, and X1 Search, a desktop product for personal home or business use.
The enterprise platform performs search and targeted collection across enterprise data sources without moving or duplicating the data, using real-time in-place indexing. Documented use cases span legal eDiscovery and legal operations; data compliance in M&A due diligence; ITAR and export-control data handled behind the firewall; cybersecurity and incident response; PCI/PII identification and management; securing data left by departed employees; privacy compliance under regimes such as GDPR and CCPA; cross-border global investigations; white-collar crime investigations; early case assessment; and litigation hold and preservation.
X1 Search lets individual users search emails, chats, attachments, local and cloud files, SharePoint documents and Microsoft 365 data from a single interface. It runs on Windows, with Windows Snapdragon (ARM) processors not supported. The company also publishes news and blog content on topics including AI in-place classification for information governance, enterprise search as a driver of AI token cost, and court decisions relating to search terms and Microsoft Teams data.
Business model
X1 sells software in two lines: an enterprise platform licensed to organizations for eDiscovery, compliance, investigations and information governance, and X1 Search, a desktop search product for individual home and business users that is distributed via a free 14-day trial with online purchase options. Sales are supported by a demo-request motion for the enterprise platform and self-service purchase for the desktop product, alongside an affiliates and partners program.
