Pivoting from a failed startup to an AI tool for creators. Need your best community-building tips!

Hey PH community, I'm in the middle of a journey that's both terrifying and exhilarating, and I could really use the wisdom of this group. For the past few years, my team and I were building an AI platform for vocational schools. The tech was solid, but the business model was a slow death – endless sales cycles and zero direct feedback from the actual users (the teachers). Our cash was running out. Instead of giving up, we decided to pivot and build something for a group of people we're truly passionate about: knowledge creators. Our new mission is to solve one of the most painful problems: turning deep knowledge into high-quality, engaging videos. We're building an AI agent platform (called X-Pilot) that acts as your personal production team. Now, we're about a month away from launching here on Product Hunt. My biggest challenge is building an initial community of early adopters who can give us feedback and help us build this right. For all the founders and community builders here, what's your #1 piece of advice for building a genuine, engaged pre-launch community from scratch? What worked for you, and what should I absolutely avoid? Thanks for any insights you can share.
