Casey Zeman argues you should run a webinar to validate a SaaS idea before building anything. You'll learn if people care about the problem, what they'll pay, and spot objections just by watching registrations, attendance, and questions. It takes weeks instead of months of wasted development.

This is where most people get it wrong. They think validation means survey beta users or quietly building an MVP in the background. I would validate the idea with a webinar. First, you see, a webinar lets you do three things simultaneously. Explain the problem, see if people care about the problem, and see if they're willing to pay for the solution to the problem. If people register, show up, and ask good questions, you're onto something. If they don't, they're you just saved yourself months of work. See, webinars are both a selling tool, but also think of them as a validation tool. They let you hear objections in real time. They let you see what confuses people. They reveal what actually matters. You learn while you're selling.
