Is Dust worth it in 2026? A detailed review

Dust Review — Overall Rating: 7.5/10

Dust is an enterprise AI assistant platform founded in 2023 in Paris by Gabriel Hubert and Stanislas Polu (formerly of OpenAI). As of April 2026, the company has raised about $16 million from Sequoia Capital and serves teams that want assistants grounded in internal company knowledge rather than just base-model knowledge.

Strengths

Dust ships managed connectors for Notion, Slack, Google Drive, GitHub, Intercom, Confluence, and Microsoft 365, with permissions inherited from the source system. This permission inheritance is a meaningful differentiator: assistants can only retrieve documents the user is allowed to see, which is often a blocker for naive RAG deployments. Builders can pick from Claude, GPT-4 family, and Mistral models per assistant.

Weaknesses

The platform competes with broader copilots such as Microsoft Copilot for Microsoft 365 customers, and with Glean for enterprise search. Dust is a smaller vendor at the 11-50 employee range and lacks the partnership footprint of larger players. Pro at $30/seat/month with credit-metered usage (July 2026) is competitive, but Enterprise quotes can climb quickly with SSO, audit logs, and additional connectors.

Verdict

Dust earns 7.5/10 in 2026. Best for European mid-market teams already using Notion-and-Slack stacks who want permission-aware assistants without committing to Microsoft. Larger enterprises with Microsoft 365 contracts may find Copilot bundled into existing licensing more economical.
