- BIG fan of UserTesting. We've used it several times to get feedback on pre-released UI from (important) people that don't know Product Hunt already. Pro tip: Be sure to have another person (ideally someone not on your team) read through the instructions and questions asked of testers. It's easy to confuse testers or ask leading questions when you're so close to your own product.
- Slightly different than what you're looking for. But I think you'd find this useful as well. FullStory records everything that your users do and then you can replay it later. So you don't get the voice over/paid tester. But you do get to see how real users experience what you've built. Which I think gives you even more valuable information than a paid tester.
When you're building a new products, user feedback is critical. You can gather feedback in a variety of ways, through in-person customer development interviews, surveys, and by simply looking at the data. I'm particularly fond of doing user testing (UserTesting is an awesome tool for this) although its only a "simulation" of what your users are actually doing.
FullStory captures a screen recording of your site visitor's actions and behavior within (cue Steve Irwin impression) their natural environment. We've used it many times at Product Hunt to better understand how people are using new or beta features we're building. It's 👍🏼.
