The Brief, formerly Creatopy, is an AI advertising platform that automates ad creation, publishing, and optimization. It generates static ads, animated banners, and UGC-style video ads in dozens of on-brand variations, then unifies competitor research (Discover), generation (Create), publishing (Launch), and performance analysis (Optimize) into a single 'AI agency' workspace. The platform helps marketing teams and agencies multiply creative output without proportional headcount. Operating as Creatopy, the company raised a $10M Series A in August 2024 co-led by European VCs 3VC and Point Nine, and has since rebranded to The Brief to reflect its expanded agentic ad-agency positioning.
