Melius

Melius is a shared creative operating system where teams of AI agents take on the production work behind images, video, and other brand assets, aimed at in-house creative and marketing teams that currently stitch together a patchwork of generative tools. The company frames the bottleneck on visual content not as model quality but as the prompt-engineering skill and disconnected tooling required to actually ship work , and this launch marks its $25M fundraise paired with a push to expand the agents lab behind the product. The company was co-founded by CEO Joowon Kim, CTO Young Kim, and COO Arnav Ramu. Joowon and Young previously worked at Ramp, Joowon as a senior engineer and Young as director of engineering and a co-founder of Venue, which Ramp acquired in 2023. Ramu is a multi-time entrepreneur who also worked in software investing at Hg and investment banking at Guggenheim. The current product is a rebuild. The team initially pursued AI-assisted performance marketing, then scrapped the entire codebase and redirected Melius toward tools that create the ad assets and campaigns themselves , which is the version launching publicly now. The round totals $5 million in seed funding led by General Catalyst and $20 million in Series A led by CRV, with participation from Genius Ventures, Vine Ventures, and Anti Fund , and the capital is earmarked for growing the team, building out go-to-market and sales, and continuing to expand the agents lab . Timing matters because Melius came out of stealth in July 2026 and, less than three months later, crossed a seven-figure run rate with thousands of teams building brand creative on the platform , so the launch catches the company at the point where it is turning early traction into a broader rollout for creative and marketing organizations.
