Prolific is a London-based scaleup that connects vetted research participants to AI companies that need human feedback to improve their models. Prolific’s platform serves industry leaders including tech giants like Google and Meta, as well as universities and research bodies.

Prolific’s niche is providing high-quality and diverse participants for online research, especially for the AI sector that requires reinforcement learning by human feedback. The company has 120k participants across seven countries, who earn $15 per hour on average for their input.

The startup announced a £25m funding round, co-led by Partech, a Paris-based VC firm, and Oxford Science Enterprises, an independent investor partnered with Oxford University. The round is the first since Prolific participated in Y Combinator in 2019, and will be used to grow its participant pool and headcount.
