Individual resellers on Depop, Vinted, and Etsy live and die by how their listings look in a feed. A single flat product photo does not compete with the short-form video content that now dominates these platforms, and most solo sellers do not have the time, skill, or software to shoot and edit video for every item they list. Enter ClipList (working name for the Micro-Creator Video Ad Generator). ClipList turns a single product photo into a short-form video ad optimized for reseller platforms: the seller uploads a photo, ClipList generates motion, pans, text overlays, and platform-specific aspect ratios, and outputs a ready-to-post clip for Depop, Vinted, or Etsy. The MVP is deliberately narrow: photo in, one polished vertical video out, with a handful of templates tuned to fashion resale and handmade goods. Revenue comes from a low-friction subscription aimed at high-volume individual sellers, likely a monthly plan with a per-video credit ceiling, plus a top-up option for power sellers listing dozens of items a week. Go-to-market rides the same channels where the target audience already learns their craft: YouTube reseller and flipping channels, plus organic content showing before and after listing transforms. The growth loop is built in: every video ClipList produces is posted publicly on Depop, Vinted, or Etsy, which means a subtle watermark or share prompt exposes the tool to the exact next customer. Sellers who see a peer's listing pop in the feed ask what made it, closing the loop.
