Creator documents building and launching an AI video automation template, AgentFast, in one week. The video covers idea validation, no-code vs code decisions, backend-first development, workflows for AI video generation and automated posting, waitlist growth, live-streamed launch, early sales, and solving manual fulfillment with Stripe-triggered onboarding automation. It emphasizes targeting builders of YouTube automation tools rather than end-users.
– Idea and market insight: pivoted from end-user tooling to selling a template for developers and builders after validating demand (an Instagram reel reached 3 million views).
– Technical approach: used large-model prompting to generate video scripts, an AI video generator for rendering, and built two flows — auto-post to YouTube and a UI-preview flow.
– Launch and traction: grew a 5,000+ person waitlist, live-streamed the launch (600 viewers) and earned initial sales via live and email/Black Friday outreach.
– Scale and fulfillment: discovered manual remix delivery was unsustainable; automated onboarding with a Stripe-triggered workflow, automated emails, Discord support, and auto-access links for buyers.

My Instagram reel about the automation got 3 million views.
53 minutes to make $97 — not bad for a first live sale.
The AI market is not saturated. You’re just focused on the wrong audience.
