Dust

Multiplayer AI platform for human-agent collaboration inside the enterprise. Dust sits as a horizontal layer on top of frontier models and a company's own knowledge, giving teams a shared workspace to build, deploy, and govern AI agents that read the same documents employees read, act across the same tools, and can be audited like any other software. It is model-agnostic — routing across OpenAI, Anthropic, Google, and Mistral — and ships a developer platform, REST API, Model Context Protocol support, and more than 100 production connectors to systems such as Slack, Salesforce, GitHub, Notion, and Google Drive. Founded in February 2023 by Stanislas Polu (CTO; former OpenAI research engineer on Greg Brockman's team) and Gabriel Hubert (CEO; former Chief Product Officer at Alan), who had previously co-founded TOTEMS, a data analytics company acquired by Stripe in 2014. Customers include Datadog, Cursor, Clay, Vanta, Watershed, and 1Password; the company reports more than 3,000 organizations on the platform and 240% net revenue retention. Raised a $40M Series B in May 2026 led by Abstract and Sequoia, with Snowflake Ventures and Datadog participating, bringing total funding above $60M.
