The AI Glue that wants to connect every marketing tool

Seattle startup Gradial has raised $65 million in Series C funding to fuel its vision of a unified AI operating system for enterprise marketing, Kerry Flynn reports for Axios. The company builds AI agents that automate workflows across the dozens of specialized tools large marketing teams already rely on, including Adobe, Salesforce, ServiceNow and Databricks.

How Gradial works

Rather than placing a separate AI assistant inside each application, Gradial positions itself as a connective layer. Its agents can identify gaps in a brand’s digital presence—such as missing from AI-generated answers—draft updates, route them through existing approval processes, and publish changes across systems. CEO Doug Tallmadge describes it as “the AI glue that makes it all work together.”

Clients like T-Mobile report dramatic results. Senior director Nick Pappas says campaign execution time fell by 80 to 90 percent, with accuracy reaching 99 percent. Early adopters include heavily regulated industries such as healthcare and financial services, where Gradial encodes compliance rules directly into workflows. This ensures AI agents consistently apply requirements that humans might overlook.

The round was led by Insight Partners and values Gradial at $675 million. Existing investors VMG Partners, Madrona and Pruven also participated, bringing total funding to more than $120 million. The company, launched in 2023 shortly after ChatGPT’s debut, was founded by four Dartmouth alumni. Tallmadge and CTO Deip Kumar previously worked on Starlink at SpaceX, while Chief Growth Officer Anish Chadalavada and COO Anup Chamrajnagar bring experience from Microsoft and Point72 Ventures.

Gradial plans to use the fresh capital to grow its 100-person team, hiring across engineering, sales and marketing. Its bet: that marketing teams need AI agents spanning entire workflows, not locked inside individual tools, so professionals can shift their focus to strategy and creativity.
