Hey, I'm still relatively new to user interviews and while ideally I'd like to be able to get 30-50 people without paying and just because they care about the problem I'm solving, I think it might be much faster for them to agree if I offer them a payment. (p.s. I don't have immediate contacts so I pretty much have to cold contact them).
Is paying people whose problem you want to solve frowned upon? What is your experience? Did you find it easy to get people for free and how did you convince them out of cold-reach?
