Zep
Agents fail without the right context. Getting it right is hard. We fixed it. Goes beyond agent memory with unified context graph, Graph RAG, and automated context assembly. Works with any framework. Three lines of code. 200ms retrieval.
Value Proposition & Features
Zep is a Context Engineering Platforms for AI agents that provides persistent, temporally-aware memory as a managed cloud service built on a temporal Context Graph (knowledge graph) architecture. [^d3o7bu] [^r1ze78] [^gl9kme] It targets developers and enterprises building AI agents that need sub-200ms retrieval, governed long‑term memory, and compliance-grade provenance rather than ad‑hoc vector stores. [^k9jjmf] [^r1ze78] [^ear82x] [^gl9kme] Zep’s commercial platform sits on top of its open‑source Graphiti engine, delivering enterprise controls, multi-tenant context graphs, and integrations with agent frameworks and MCP-based tools. [^r1ze78] [^s34gjv] [^dnww73]
Core product features:
- Zep’s Agent Memory service extracts entities and facts from conversations and business data, stores them in a temporal knowledge graph, and serves relevant context back to agents at request time. [^k9jjmf] [^r1ze78] [^7cee07]
- The Context Graph / Context Lake provides bi-temporal edges with validity intervals and fact invalidation, enabling queries like “what was true at time X” versus “what is true now,” and auditing how knowledge evolved over time. [^it7zro] [^s34gjv] [^7cee07] [^ear82x]
- Graphiti, the open‑source engine behind Zep, powers hybrid retrieval (embeddings + BM25 + graph traversal) with sub‑200ms reads, and can be used standalone with a bring‑your‑own graph database. [^k9jjmf] [^r1ze78] [^s34gjv] [^4kbl3v]
Priority feature list (5–8 bullets):
- Temporal Context Graph (bi‑temporal knowledge graph) — facts stored as edges with event time, ingestion time, and validity intervals, supporting “what used to be true” queries and audit trails. [^it7zro] [^s34gjv] [^7cee07]
- Hybrid Retrieval (search + graph traversal) — recall queries run semantic similarity and BM25 search over nodes and edges, fuse results, then traverse subgraphs via BFS and related algorithms to assemble context efficiently. [^k9jjmf] [^s34gjv]
- Observations & Pattern Detection — Zep builds cross‑conversation patterns as “Observations,” durable, evidence‑backed summaries of what the graph shows about users or problems rather than just episodic facts. [^85fffn] [^tdli9z] [^19qz3y]
- Provenance & Lineage Tracking — every derived fact links back to raw episodes, enabling veracity checks, source attribution for LLM‑synthesized answers, and compliance use cases such as GDPR deletion. [^19qz3y] [^ear82x] [^xbk61n]
- Managed Cloud Context Graph Engine — Zep Cloud includes a proprietary graph runtime with SLAs, sub‑200ms retrieval, and no need for a third‑party graph database, unlike Graphiti which requires BYO graph store. [^r1ze78] [^4kbl3v]
- Agent Framework Integrations & MCP — integrations and guides for Claude Code, Codex, Cursor, Strands, Eve, and Memory MCP let agents use Zep for long‑term memory with minimal setup. [^5cja6r] [^mscs7u] [^eg3e7p] [^dnww73]
- Enterprise Governance & Access Control — attribute‑based access control on graph edges and episodes, user/group policies, and controls for write permissions on MCP connections. [^u5eosb] [^f1avlu] [^dnww73]
- Strict Ontology & Ingestion Pipeline Support — strict ontology flags and ingestion guides ensure only configured entity/edge types are added, with batch APIs and data‑prep guides for production pipelines. [^2disjl] [^w73flu]

History and Origin Story
Zep AI was founded in 2023 and participated in Y Combinator’s Winter 2024 batch, building a temporal knowledge‑graph memory layer for AI agents. [^qcn0hv] [^70mwoi] [^h4oxmk] The founding team centers on Daniel Chalef (founder/CEO), joined by co‑founders including Paul (Pavlo) Paliychuk and Preston Rasmussen, who introduced the project via “Show HN: Zep, Open-Source Graph Memory for AI Apps” alongside the open‑sourcing of Graphiti. [^h4oxmk] [^70mwoi] The company’s origin story is tied to solving “agent context is hard” by publishing the “Zep: A Temporal Knowledge Graph Architecture for Agent Memory” paper and turning its Graphiti engine into widely adopted open‑source infrastructure for agent memory.

| Enterprise | Custom; usage‑based credits, negotiated rates, deployment options and SLAs | SOC 2 Type II, HIPAA BAA, BYOK and enterprise features. [^4owm04] [^sm5hqw] [^9csuah] |
Other third‑party sources mention starting pricing “from $25/mo” or “from ~$125/month,” but these are secondary summaries; the most detailed tier descriptions are from Zep’s docs, Systemaic, and HydraDB. [^bk2yms] [^sm5hqw] [^lz0kr9] [^3aph03] [^1uyakk]
Revenue Trajectory Estimates
Systemaic’s teardown states that Zep’s revenue is not publicly disclosed and offers a qualitative estimate that, given enterprise contracts alongside $104–$312/month self‑serve tiers and a lean team, revenue is “plausibly in the low‑to‑mid six‑figure annual range,” emphasizing this is an estimate, not a confirmed figure. [^bk2yms] Y Combinator’s job listing for Zep notes that the company is seed‑stage with 50% month‑over‑month ARR growth and 240+ customers including Fortune 500s, but does not disclose exact ARR. [^70mwoi]
Competitive Landscape
Who it’s for, who it’s not for
Zep is for developers and enterprises building AI agents that require persistent, temporally-aware memory with strong governance, compliance, and provenance, especially where understanding how facts change over time and across conversations is critical. [^k9jjmf] [^r1ze78] [^7cee07] [^l9cdbw] [^70mwoi] It is particularly suited to production AI agents, copilots, and enterprise applications needing sub‑200ms retrieval, SOC 2/HIPAA controls, attribute‑based access control, and multi‑tenant context graphs served inside VPCs or controlled cloud deployments. [^r1ze78] [^70mwoi] [^9csuah] [^dnww73] [^l9cdbw]
Zep is less suited for teams that require fully self‑hosted managed memory products with no external SaaS component, since independent analysis indicates the Community Edition is deprecated and Zep is now a hosted‑only product, leaving self‑hosting to Graphiti plus custom plumbing. [^9v5f60] [^97r09g] [^4pl8xt] [^1uyakk] It is also not ideal for simple, lightweight memory where a flat key‑value store or basic vector DB suffices, or for teams whose budget or complexity requirements favor lower‑cost, simpler memory APIs without temporal graphs and governance overhead. [^hu5yt4] [^37gaf1] [^kv8ehv] [^0rno0i]
