Startup cost: $0 - $200

Prolific is a platform for participating in research studies, so the initial cost is minimal. On the low end, you can start with just a computer and internet access, which you likely already have. On the high end, you might invest in a faster internet connection or a more comfortable workspace setup, such as a better chair or desk, to improve productivity. There are no hidden fees, and the cost is generally low, as confirmed by online communities.
