Seattle-based Gradial closed a $65 million Series C on June 17, bringing its valuation to $675 million. Insight Partners led the round, with participation from VMG Partners, Madrona, and PruVen Capital.

The company has now raised more than $110 million in the past 16 months. It raised a $13 million Series A in March 2025, a $35 million Series B in December 2025, and this Series C just six months later.

Gradial builds what it calls a “system of work” for enterprise marketing. AI agents execute tasks across tools large organizations already use, including Adobe, Salesforce, ServiceNow, and Databricks, without requiring humans to route work through approval steps manually.

CEO Doug Tallmadge described the core product philosophy simply: “You should have an agent that spans across your workflow, not a separate agent for every step of the workflow.”

The company, officially incorporated as Panorama Artificial Intelligence Corp., was founded in 2023 by four Dartmouth College alumni. Tallmadge previously worked as a software engineering manager at SpaceX. Chief growth officer Anish Chadalavada held AI strategy roles at Microsoft and Point72 Ventures. CTO Deip Kumar also worked at SpaceX and Microsoft. COO Anup Chamrajnagar came from Point72.

Enterprise clients include AWS, Prudential, T-Mobile, Vanguard, Kaiser Permanente, and U.S. Bank. T-Mobile senior director of digital business management Nick Pappas said the platform cut campaign execution time by 80% to 90% while maintaining 99% accuracy. Some customers have compressed service-level agreements from 10 days to same-day delivery while staying compliant with internal brand standards and Web Content Accessibility Guidelines.

Gradial argues that marketing teams currently spend up to 80% of their time on manual, repetitive tasks rather than creative strategy. Its agents handle the full content supply chain, from drafting and routing to publishing, while applying brand and compliance rules automatically.

Early adoption has been heaviest in regulated industries. Healthcare and financial services companies have used Gradial to encode compliance requirements into workflows so agents apply rules consistently, reducing the risk of human error.

Teddie Wardi, managing director at Insight Partners, said businesses are entering a period where AI is reshaping how consumers discover and engage with brands, making the case for autonomous execution tools more pressing.

Gradial plans to use the new capital to expand its 100-person team, hiring across engineering, sales, and marketing. The company positions itself not as another point tool but as the orchestration layer connecting the agents and platforms enterprises already run.

Madrona managing director Matt McIlwain, who backed the company at the Series A stage, said Gradial stands out among AI startups for the measurable return on investment it delivers to enterprise clients.
