Currently you have a couple of options. You could use a user testing product like UserTesting.com, but here you'll find professional participants - mostly college students and stay at home parents who do research as a side hustle.
The second option is to do no research at all, since it's hard to find a completely unbiased audience.
Our approach helps you build a panel of folks who are at least your own customers - or lookalike customers. We've seen customers recruit runners, engineering managers, shift workers, entrepreneurs, and delivery drivers. It all depends on who your customer is and what you're looking to achieve.
You will likely get a mix of folks participating, and each for different reasons. Some will do it for the incentive if there is one. Others are more intrinsically motivated - they're doing it because they either love the product a lot, or they really hate it and want it to improve.
It's hard to find the "average joe" who is on the fence but is still somehow motivated to participate in your research.
We provide tools to help you screen out folks based on different attributes (HN consumption could be screened out to some extent) to make the best of an imperfect world. Still better than professional participants doing it only for the money, and significantly better than no research.
