Dust, a multiplayer AI platform for enterprise collaboration, has announced a $40 million Series B funding round. The round was spearheaded by Abstract and Sequoia, with participation from Snowflake Ventures and Datadog. The announcement came on May 18, 2026, from the company’s headquarters in San Francisco, California. The funding will help Dust scale its human-agent collaboration platform across organizations worldwide.
Most organizations currently use AI in silos, which Dust calls “single-player AI.” One employee prompts an assistant and gets an answer, but the context disappears into a private chat window. The result is individual productivity with very little compounding across teams. Dust was built to change this by making AI collaborative, shared, and operational across an entire company.
Dust gives business teams a platform to build, deploy, and manage AI agents that collaborate across an organization. These agents connect to company knowledge and integrate with tools teams already use. The platform includes enterprise-grade controls such as granular permissions, cost monitoring, audit trails, and agent analytics. Dust is SOC 2 Type II certified, GDPR compliant, and does not train models on customer data.
Dust is now used by more than 3,000 organizations globally. Monthly active adoption is consistently above 90 percent, with weekly active usage above 70 percent across customers. More than 300,000 agents have been deployed across the platform. In 2025, Dust achieved 240 percent net revenue retention with zero churn. The company has quadrupled its team to 100 employees.
At Vanta, 900 people across sales, customer success, and revenue operations save thousands of hours each week using Dust. At Clay, the platform serves as foundational knowledge infrastructure, enabling the team to grow four times without a proportional increase in headcount. At Persona, teams across 11 departments have deployed over 300 Dust agents, compressing sales RFP workflows from days to minutes. Doctolib now gives 3,000 employees smoother access to corporate information through Dust.
Dust was founded by Gabriel Hubert and Stanislas Polu, who have been building together since meeting at Stanford in 2007. They previously co-founded TOTEMS, a data analytics company acquired by Stripe in 2014. Polu later joined OpenAI as a research engineer on Greg Brockman’s team, co-authoring papers on AI reasoning with Ilya Sutskever. Dust incorporated in February 2023 to build a horizontal layer on top of frontier models and company knowledge.
Konstantine Buhler, Partner at Sequoia, said most enterprise AI today is single-player with no compounding effect. He noted that zero churn and 70 percent weekly active usage show Dust is no longer experimental. Ramtin Naimi, General Partner at Abstract, added that Dust is creating a new operating model and category. He highlighted that AI Operators inside companies like Datadog and 1Password build agents that collaborate across teams and rewire how entire companies work.
This $40 million funding round positions Dust as a leader in the emerging multiplayer AI category. The company plans to push three frontiers next: agents that learn automatically, collaboration primitives that make humans and agents equal co-contributors, and infrastructure for enterprise-scale governance. The bet is that the next phase of enterprise AI will be won by who turns AI into shared, compounding capability across the entire organization, not who has the best single assistant.
