Since our inception 4+ years ago, we've grown our tester community of 150,000 largely organically and through referrals from other testers, but also through marketing and tester outreach efforts.
Our community includes a very wide variety of demographics, interests, and abilities: Professionals, students, moms / dads, developers, and everything in between.
The common thread is that all our testers are passionate about providing feedback and playing a meaningful role to help you launch better, more successful products. In exchange for their quality feedback, each tester earns a reward. We coordinate incentives, so you don't have to (the cost is already included in our pricing).
