Solo SaaS founders ship new features constantly but rarely have a video team. Recording a clean product walkthrough means screen capture, scripting, narration, editing, and formatting for each platform. Most skip it entirely or post static screenshots that get ignored in feeds. StoryShort for SaaS Demos closes that gap. The founder pastes a URL, drops in a short script, and the tool generates an AI-narrated product demo video sized and ready for Twitter and LinkedIn. The MVP is narrow on purpose: URL ingestion to capture the product UI, script-to-narration via text to speech, auto-pacing of on-screen walkthrough, and export in vertical and square aspect ratios for social. Revenue is a straightforward subscription: a monthly plan with a video credit allowance plus an overage or higher tier for founders who ship weekly. The main competitor StoryShort already shows payment-verified MRR around 18,767 per month, which signals real willingness to pay for short AI video generation. Go to market starts where the buyers already congregate: Launch HN style posts, build-in-public Twitter and LinkedIn threads, and indie founder communities. The core growth loop is built in. Every generated video is itself distribution. If each demo carries a subtle made with attribution or simply performs well on LinkedIn and Twitter, other founders watching those feeds see the format and ask how it was made. Feature launches are recurring events, so a founder who gets one good demo comes back for the next release, making retention tied to product cadence rather than novelty.
