Sentra provides an organization-wide memory layer that connects fragmented systems (CRM, tickets, repos, docs, meetings, mail) into a single governed context graph that both people and AI agents read from as one source of truth. It resolves facts at write time, tracks when facts become and stop being true via a bi-temporal knowledge graph, and exposes the graph through REST and MCP so applications and agents share the same current context.
