Our pricing is straightforward and transparent:
- Self-serve: You pay a participant reward that you set, plus a platform fee.
- Self-serve Plus and Managed services: Pricing is customized based on your project scope and requirements.
For self-serve users, our platform fee is usually 42.8% for corporate customers, and a discounted 33.3% for academic or non-profit customers.
Typically, we recommend you pay participants at least £9.00 / $12.00 per hour, while the minimum pay allowed is £6.00 / $8.00 per hour. For tasks requiring specialized skills (like experience in AI annotation tasks, coding experience, or advanced STEM degrees), we recommend higher compensation, to reflect their expertise and the complexity of the tasks. Fair compensation leads to better data quality and higher engagement, especially when publishing complex tasks or studies.
You don’t need to sign a contract or pay for a subscription to get started. You can simply pay as you go by adding funds to your wallet and launching a study or a task.
Our participant management service includes a dedicated support to coordinate all participant needs. This usually includes delivering any custom training modules, curating the right pool of participants, monitoring engagement, quality assurance, and strategic planning to build participant pools for ongoing needs.
