Hey Product Hunt! 👋 I built SignalLab after building too many products nobody wanted. I hated finding potential users and interviewing them to find out if my product was worth building. I'd skip this step, and well, you know the rest. The turning point came when I realized: what if I could have a conversation with my target customer *before* I built anything? Not surveys (people lie), not landing pages (too shallow), but actual back-and-forth dialogue that reveals real objections and enthusiasm. That's SignalLab. You describe your idea and target market, and we generate AI personas that act like real potential customers. They'll push back, ask tough questions, and tell you what they actually think—not what you want to hear. I'd love your feedback. What would make this more useful for validating your own ideas?
