Asana has completed its acquisition of workflow automation company Stack AI for $75 million, marking a significant step in its strategy to establish itself as an AI-native workplace platform. As part of the deal, Stack AI’s co-founders, Tony Rosinol and Bernard Aceituno, will join Asana. The company positioned the purchase as part of a broader AI shift, aiming to transform its platform into what it calls "the operating system for human-agent teams."

The announcement came Thursday afternoon, coinciding with Asana’s earnings report and investor call. Stack AI, originally built as an AI-powered workflow automation system, designs agents that operate within existing business tools, pulling data from platforms like Salesforce, Slack, and G Suite. As part of Y Combinator’s Winter 2023 cohort, the startup has faced intense competition from automation platforms like Zapier and AI labs such as OpenAI and Anthropic.

According to PitchBook data, Stack AI had raised just under $20 million, with the bulk coming from a recent $16 million Series A round. That round included investments from Gradient, Epaklon Capital, Lobby VC, LifeX Ventures, and Vercel CEO Guillermo Rauch. While many users know Asana primarily for its work management system, the company has launched several AI-focused products in recent years, notably its AI Studio agent builder and AI Teammates, a series of pre-built automations.

Although similar tools are available from major AI labs, Asana views its deep integration into corporate workflows as a key differentiator, enabling it to capture context and training data that competitors might lack. On public markets, Asana has struggled during the AI era, losing more than half its market capitalization since ChatGPT’s introduction—a decline that worsened after founder Dustin Moskovitz stepped down as CEO last March. Still, revenue has continued to grow steadily, and the new leadership is optimistic that its human-agent products will drive a rebound.

"This acquisition accelerates our roadmap and takes us into the next phase of human-agent work," said CEO Dan Rogers in a statement. "We’re already seeing real momentum with AI Teammates and AI Studio… Stack AI now lets them go further, agentifying the most complex business processes end-to-end."
