Melius raises $25M to build AI agents for ad creative

Three former Ramp engineers announced on October 6 that Melius raises $25M to fund what they call the first agents lab for creative work. Melius, a New York startup that emerged from stealth in July 2026, positions its multi-agent platform as a shared creative operating system where teams of AI agents handle the production work between a plain-language prompt and a finished asset.

According to the announcement carried on GlobeNewswire, the Melius raises $25M total combines $5 million in seed funding led by General Catalyst with a $20 million Series A led by CRV. Other participants include Genius Ventures, Vine Ventures, Anti Fund, and angel investors. The company said it will use the capital to grow headcount, build out a go-to-market and sales organization, and continue expanding its agents lab. The story was first reported by TechCrunch, which detailed the founders' unusual path to the raise.

The Melius raises $25M backstory is unusually candid. The founders — CEO Joowon Kim, CTO Young Kim, and COO Arnav Ramu — spent more than six months building an AI tool to help marketers manage ad spend, then concluded the product lacked momentum and discarded the entire codebase. They rebuilt around a different thesis: that the bottleneck in visual content production is not model quality, but the prompt-engineering skill and patchwork of disconnected tools required to use generative AI. The company now describes a system where a user types a plain-language prompt and receives advertising copy, still images, or video content in return.

Traction claims behind the raise

Melius reports crossing a seven-figure annual run rate within three months of introducing its agentic creative operating system, and says thousands of teams are actively using the platform. According to reporting by citybiz, the Melius raises $25M pitch names Doors.com, Slash, SkinnyDipped, and Shown Media among its partners, though no specific revenue figures or named enterprise customers have been disclosed. The company did not disclose a valuation for the round.

The co-founders' backgrounds are firmly in engineering and finance. Joowon Kim and Young Kim previously worked together at Ramp, the corporate-finance software company; Young Kim co-founded procurement software company Venue, which Ramp acquired in 2023, and later led its procure-to-pay engineering organization. Ramu brings experience as a multi-time entrepreneur, software investor at Hg, and investment banker at Guggenheim.

A crowded market for creative agents

Melius is entering a field that is already dense. Reported by TechCrunch and carried on Tech Weekly, the founders acknowledge the competition directly: Higgsfield, a competitor in the same space, reached a $5.4 billion valuation in August 2026 and said it had climbed past $700 million in annualized revenue. Other players include Krea and Flora AI. The Melius raises $25M round gives the startup capital to compete in a segment where creative generation is rapidly becoming table stakes.

Kim has argued publicly that the crowded field is evidence of real customer demand rather than overcapacity, and that the market is large enough to support multiple winners. The claim has some backing: the broader arc of marketing technology has shifted from tools that optimize budgets and manage campaigns toward tools that generate the creative assets themselves. Melius is betting that agent orchestration — coordinating multi-agent teams that produce editable, finished work — becomes the durable advantage. A related bet on agent-mediated advertising is covered in pubX's $5M raise for agent-to-agent advertising, while Flozic's autonomous agent launch shows the same orchestration thesis spreading across enterprise apps.

Why investors keep funding AI agent startups

The Melius raises $25M round is part of a sustained wave of agent-focused funding. The same week saw Butterfly Effect, parent company of the general AI agent Manus, raise more than $500 million at a reported $4 billion valuation, and Stuut secure $52.5 million in Series B funding for order-to-cash AI agents. Investor logic is converging on a clear thesis: agents that deliver finished work products, not just answers, are where enterprise budgets are heading.

For Melius, the test ahead is proving that its agents lab can become a durable operating layer rather than another set of tools creative teams must manage. The company has institutional capital, a founding team with deep engineering pedigree, and early commercial signals. Whether the Melius raises $25M bet pays off will depend on retention, margin, and customer concentration data that the company has not yet disclosed.
