I'm just trying to prepare to start preselling my own tool, https://digitalfirst.ai. I'm trying to see this as the truest, most sincere validation that could be, since you're asking people to grab their wallets, not just share their opinion. I'm not hoping for great scale, but even if few people will declare that the idea is worth paying - I'm on good path :) Right now I'm looking for every good tip for the communication and offer. What do you think will convince people most? Money back? Stripe payment? Beta-testers testimonials? Not so sure.
