How do you collect feedback from beta users before your PH launch?

I have launched on PH twice but before launching, I always prefer to share the product with at least 20 potential users over DM. The goal is to get early feedback and testimonials. This helps me understand what’s working (or not) in the copy, design, offer, value proposition, etc.

Based on those early insights, I iterate quickly and it could be small tweaks or full rewrites, depending on what people are saying.

To make it easy for them to say yes and share feedback, I create a no-brainer offer (like 70–90% discount) and DM potential users on X asking for feedback.

What’s your pre launch strategy for collecting feedback and improving your product before launching on PH?

P.S. Here’s a sample DM I use to get early feedback for Boringlaunch:

Hey [User Name] 👋
