I’m an indie solo dev selling label printer software. The niche force is strong with me... my business is basically selling the software equivalent of colonoscopies. I can only speak for my own experience, but Capterra offered me and my customers something like $20 gift cards for the first 100 reviewers and I sent 500 emails with this offer and maybe had 1 reviewer bite and then later said he never received a gift card. But my app has 15 reviews and I asked maybe half of those users to write a review after they first emailed me with a testimonial/praise. https://www.capterra.com/p/182776/Label-LIVE/ https://www.capterra.com/p/182776/Label-LIVE/
