Sinequa

Sinequa is an enterprise AI search platform that combines deep document understanding with grounded retrieval-augmented generation (RAG). Unlike generic LLMs, Sinequa indexes your organisation's internal documents and generates answers directly tied to those sources, reducing hallucinations. Founded in 2002, the company has spent two decades building connectors to enterprise systems like SharePoint, Confluence, Salesforce, and ServiceNow, giving it a rare advantage: immediate integration with existing document repositories. The platform supports on-premises and air-gapped deployment, making it one of the few options for regulated industries including defence, pharma, and government. Sinequa Assistant lets employees ask natural questions and receive grounded answers from their organisation's knowledge base rather than relying on generic AI responses. The platform serves Fortune 500 companies and government agencies managing massive document estates across multiple systems. Its 200+ pre-built connectors mean implementations can start quickly without building custom integrations from scratch. The on-prem option is critical for organisations with strict data residency requirements or air-gapped networks that cannot use cloud-based alternatives.
