Cognee AI Memory Engine

Cognee, operated by Topoteretes UG in Berlin, was founded in 2024 by CEO Vasilije Markovic. It builds an open-source memory engine that lets AI agents retain and recall company knowledge, and raised a $7.5 million seed round led by Pebblebed in February 2026.

Its Extract, Cognify, Load pipeline ingests data from 38+ sources and structures it into a searchable knowledge graph with embeddings, combining relational, vector and graph storage in one engine. Teams can use the open-source install, Cognee Cloud or a bring-your-own-cloud deployment, with integrations for Claude Code, LangGraph, CrewAI and an MCP server. More than 70 companies reportedly run it.

• Remember: ingests data from 38+ sources into a knowledge graph with embeddings.
• Recall: agents query structured memory through SDKs and an MCP server.
• Improve: a feedback layer refines the graph over time.
• Ontologies: custom data models and a built-in ontology generator for domain rules.
• Permissions: access controls over what agents can recall.
• Deployment: open-source install, Cognee Cloud or bring-your-own-cloud.

A Vietnamese bank or telco can give a support agent memory of policies, tickets and product documents. A software company can let coding agents recall repository and issue history across sessions.

Gives agents persistent, structured memory instead of stateless prompts. The core is open source, so teams can start without licence cost, and bring-your-own-cloud keeps data in the customer environment. The site lists 33k GitHub stars and permission controls for governed access.

Enterprises moving AI agents into production need persistent memory and governed knowledge rather than one-off context windows, which is creating a new data infrastructure layer. Vietnamese software teams building internal assistants can adopt open-source tooling to prototype such memory locally.
