Onyx
Open-source enterprise AI assistant (formerly Danswer) — self-hosted search, RAG and chat over 40+ internal data sources; $10M seed [1][2].
1. Core Product / Service
Onyx (onyx.app, formerly Danswer) is an open-source enterprise AI assistant for search and chat over a company's private data [1]. It connects to 40–50+ data sources (Salesforce, GitHub, Google Drive, Slack, Confluence, Notion, and more), then layers retrieval-augmented generation, assistants, web search, and MCP support over a self-hosted, MIT-licensed Community Edition — with paid enterprise tiers adding SSO, RBAC, and analytics [1].
Launched in 2023 as Danswer ("deep answer") and rebranded Onyx around 2024, it positions self-hosting and data control as its differentiator against SaaS-first enterprise assistants [1][2]. Note: it is distinct from Onyx Security, a separate AI-agent-governance company.
2. Target Users & Pain Points
- Enterprises that want a ChatGPT-like assistant grounded in their own documents without sending data to a third party (data-sovereignty / compliance).
- Organizational multi-user teams evaluating open-source knowledge management — the context of Jimmy's 2026-09-19 research comparing Onyx against dify for Lark-based multi-tenant agent setups (Onyx noted for memory/knowledge-management strength) [local].
Pain solved: knowledge fragmentation across SaaS apps, with strict access control and the option to run everything on-prem.
3. Competitive Landscape
| Platform | Type | Vs. Onyx |
|---|---|---|
| Onyx | Open-source enterprise search + RAG | Self-hosted, connector breadth, access control |
| dify | Open-source LLM app/agent platform | General app builder; less search/connector-first |
| glean | Commercial "Work AI" platform | Managed SaaS, permissioned graph; closed source |
| Microsoft 365 Copilot | Hyperscaler assistant | M365-native, closed |
Onyx is the open-source pole versus commercial glean and Copilot — same enterprise-search mission, self-hostable and model-agnostic [1].
4. Unique Observations
- Open-source as the wedge into enterprise search. The bet is that CIOs distrust sending internal data to closed SaaS assistants and will standardize on a self-hostable, auditable alternative — the classic open-source go-to-market [1].
- Chat-UI pivot from pure search. The Danswer→Onyx rebrand marked a shift from "search over documents" to a full chat/assistant interface with RAG, agents, and deep research — chasing the agentic-assistant market rather than staying a search box [1].
- Seed-only, unlike the AI4S wave. At $10M raised, Onyx is capital-efficient against peers, but faces distribution pressure from glean's scale and Microsoft's bundling [1][2].
5. Financials / Funding
- Founded: 2023 (as Danswer), YC W24; San Francisco [1].
- Seed (Mar 2025): $10M, co-led by Khosla Ventures and First Round Capital, with Y Combinator and angels Gokul Rajaram, Arash Ferdowsi, Amit Agarwal [2].
- Customers: Netflix, Ramp, Thales Group [2].
