Sourcing Memo: Tribal Knowledge → Agent-Usable Context
1. Glean — Enterprise search + knowledge graph across SaaS apps, now exposing that graph to agents via APIs. Fits as the category anchor, though late-stage (~$7B val); useful as the "incumbent risk" benchmark rather than a target.
2. Unstructured — Converts messy enterprise docs (PDFs, emails, decks) into LLM/agent-ready structured data. Series B, strong OSS adoption; the ingestion layer of this thesis.
3. Dust — Platform for building enterprise agents grounded in company data/connections (Notion, Slack, Drive). Paris-based, Sequoia-backed, early but with real mid-market logos; founded by ex-OpenAI/Stripe.
4. Credal — Secure layer connecting internal knowledge sources to LLMs/agents with permissioning and audit. Early-stage (Spark-backed), fits the "agents need permission-aware context" angle precisely.
5. Onyx (formerly Danswer) — Open-source enterprise search/RAG over internal tools, evolving toward agent-facing knowledge APIs. Seed-stage, YC, strong OSS traction — classic bottom-up wedge.
6. Sana (Sana AI) — Knowledge platform turning company docs, meetings, and training content into an assistant/agent layer. Stockholm-based; started in learning, pivoting hard into agentic knowledge work.
7. Graphlit — API-first platform for building knowledge graphs from unstructured enterprise content for RAG/agent apps. Very early, developer-focused; a picks-and-shovels bet on context infrastructure.
8. WRITER — Enterprise genAI with a proprietary "Knowledge Graph" that grounds agents in company data/terminology. Growth stage but a signal that grounding in tribal knowledge is the enterprise buying criterion.
9. Zep — Memory and knowledge-graph layer (Graphiti OSS) for AI agents, persisting learned org/user context over time. Seed-stage; addresses the "agents forget everything" gap directly.
10. Guru — Captures verified team knowledge (cards, expert verification) and now pipes it into AI answers/agents. Older company, but its human-verification workflow is exactly the trust layer agents lack — potential acquisition comp.
(Deliberately excluded some I couldn't verify still operate independently.)

White-space gaps
1. Passive tribal-knowledge capture. Nearly everyone indexes what's already written down. The real tribal knowledge lives in Slack threads, Zoom calls, code review comments, and hallway decisions — nobody has nailed ambient capture → structured, permissioned context with human verification in the loop. Guru's verification model + Zep's memory model, but passive.
2. Context provenance & decay. No one is building the "freshness and trust layer": which context is stale, who vouched for it, what an agent is allowed to assert vs. must caveat. As agents act (not just answer), liability for acting on outdated tribal knowledge becomes a budgeted enterprise problem — and there's no clear owner of that layer today.
