Paris-based Dust, the “multiplayer AI system for human-agent collaboration”, announced a $40 million Series B investment round with Sequoia and Abstract, with participation from Snowflake Ventures and Datadog.

With this round, Dust has raised over $60 million in total funding.

Dust said it is used by more than 3,000 organizations globally, from high-growth AI-native companies to established enterprises.

“Most organizations are stuck in what Dust calls single-player AI,” said the Paris firm.

“Every employee has their own assistant with its own context and its own outputs. A sales rep researches an account, then the solutions engineer starts from scratch the next day. Marketing drafts a one-pager, then enablement recreates a battlecard with different inputs. The effort repeats, knowledge fragments, and gains don’t compound.

“Dust argues that most AI tools used by enterprises reinforce this pattern. Foundation model workspaces and copilots are powerful, but they’re primarily designed around one individual’s workflows and context. Enterprise search tools retrieve information, but don’t take action.

“The outcome is more activity and more AI usage at the individual user-level, but not an intentionally designed system that compounds AI into shared leverage.”

Gabriel Hubert, co-founder and CEO of Dust, said: “This is a century-defining transformation, and we’re only in year three.

“What will transform the way we work isn’t the next best model or assistant. It’s going to be a completely new type of system that gives humans and agents shared, governed access to the same information and capabilities so that they become true collaborators, working with the same context, notifications, artifacts, and goals to compound organizational impact.

“This is what we call multiplayer AI, and this is what we’re building at Dust.”

Konstantine Buhler, Partner at Sequoia, said: “We’re in the early innings of a massive shift in how organizations use AI.

“Most enterprise AI today is single-player: one person, one prompt, no compounding. Dust is building the multiplayer system, where agents and humans share context and work together across the entire company. Zero churn and 70% weekly active usage tell you this isn’t experimental anymore. This is how enterprises will actually operate.”

Ramtin Naimi, General Partner at Abstract, said: “Dust is multiplayer. AI Operators inside companies like Datadog and 1Password don’t just use Dust; they build agents that collaborate across teams, learn from every interaction, and rewire how the entire company works. That’s a new operating model and category. That’s why we participated in this round.”
