After having an idea for an online course how do you validate it before recording the course?
Also how do you discover new niches around your knowledge area?
The fastest validation I've seen work: post in communities where your ICP hangs out, ask a specific question tied to the problem your course solves, and see who engages with depth. Genuine pain shows up in how people respond - length, specificity, follow-up questions.
For Notion-based products specifically, validating at the 'system' level vs. the 'template' level matters. People will say yes to a template but they pay for a system that solves a workflow problem they have right now.
Validating a Solopreneur Notion OS right now using exactly this approach - community comments asking about ops pain points (CRM, project tracking, revenue visibility). Seeing strong signal from solo founders at /bin/bash-5K MRR. What problem does your course idea solve, and have you found the conversations that confirm the pain is real?
