Crowd Manager perfectly captures the idea. This is a person who achieves business requirements by delegating jobs to a large number of performers in a crowdsourcing system.
This managers' role in these initiatives is to coordinate data labelling and quality control processes so that as many labelers as possible are involved. Crowd Manager creates many jobs for comparing two things, and it only takes a few hours for thousands of workers to vote on which one they prefer. It is safe to use.
