I built a testimonial collection tool — here's what I learned

I'm building TrustWall — a tool that lets you collect testimonials with a simple link and display them on your site with embeddable widgets. Why I built it Every SaaS founder I talked to had the same problem: Happy customers, but no testimonials on their site Asking for reviews feels awkward Displaying them nicely takes dev time What I learned Email is the #1 channel for collecting testimonials — 68% response rate with the right ask. The #1 thing that surprised me: email is the best channel for collecting testimonials — 68% response rate when you ask within 7 days of delivery. Tech stack Next.js + React + Tailwind Supabase for the backend Stripe for billing Hosted on Vercel Would love feedback from the dev community. What would make you actually start collecting testimonials for your side projects?
