Egregore Labs develops Egregore, an open-source shared cognition layer that provides memory, context, and coordination primitives for teams collaborating with AI agents using Claude Code. It accumulates session handoffs, decisions, patterns, and workflows into a git-based shared knowledge repository symlinked into each instance. The technology relies on shell script hooks triggered by Claude Code events for syncing memory, isolating worktrees, and tracking activity, along with slash commands like /handoff, /activity, /invite, /deep-reflect, and /quest. Egregore operates without background processes or daemons, using markdown files and git for version-controlled provenance. Co-founded by Oguzhan Yayla, with a computer science background from Istanbul Bilgi University, and Cem F Dagdelen. The company is located in Berlin, Germany.
