Solid is the AI creative engine for brands and their agencies. The Solid Agent turns a brand's own footage, voice and best ads into finished video ads for Meta, TikTok and YouTube. From a brief, it writes the script, adds the voiceover, picks the scenes, assembles the ads and creates variations in hooks, formats and languages. Real footage first, generation built in: the Smart Library cuts every upload into searchable scenes, the Brand Hub keeps every ad on brand, and when a shot is missing, leading video and image models fill the gap. Every step stays editable: script, voice, scenes and the final cut. Brands like HOLY, TEVEO, Too Good To Go and Just Russel use Solid to ship more winning ads, faster. Founded in 2025 in Berlin.
