Seattle startup Gradial raised a $35 million Series B round to expand its AI platform that automates the behind-the-scenes work of enterprise marketing. VMG Partners led the round, with participation from existing backers Madrona and Pruven Capital.

It’s the second round of funding this year for Gradial, which raised $13 million in May. Total funding is $55 million. The company is valued at $350 million.

Gradial is targeting what it calls the “content supply chain” — the workflows that move marketing content to live campaigns. Its AI “agents” plug into existing systems to handle tasks such as CMS authoring, brand redesigns, QA, and large-scale campaign operations.

“Every enterprise marketing team faces the same challenge. Their current tools and processes are too fragmented for them to move at the speed they need,” co-founder and CEO Doug Tallmadge said in a statement. “Gradial agents live inside the workflow and learn to do the work just like a human employee would.

Customers include AWS, Prudential, and T-Mobile. Gradial was featured during AWS CEO Matt Garman’s keynote presentation this week at AWS re:Invent.

Gradial sits in a fast-growing category of “agentic” AI tools that go beyond content generation to orchestrate complex workflows in real time.

“Gradial’s agents don’t just assist; they perceive, decide, and coordinate in the flow of real work,” Madrona wrote in a blog post. “They represent a new class of reasoning machines that work alongside humans to manage complexity, turn feedback into foresight, and compound improvement over time.”

Tallmadge previously worked at SpaceX as a software engineering manager. Other co-founders include chief growth officer Anish Chadalavada, a former AI strategy manager at Microsoft and investor at Point72 Ventures; CTO Deip Kumar, who also worked at SpaceX and Microsoft; and COO Anup Chamrajnagar, who worked at Point72. All four co-founders graduated from Dartmouth College.

Gradial raised $5.4 million in a seed round in February 2024. The company employs around 50 people.
