Overview
Toloka is a data company founded in 2014 and headquartered in Amsterdam that supplies human-generated training, fine-tuning and evaluation data for artificial intelligence systems. It began as a large-scale crowdsourcing platform and has repositioned around expert work, combining domain specialists, machine learning tooling and quality control pipelines to produce reasoning traces, preference rankings and agentic task data. Operating within the Nebius group and backed by Bezos Expeditions since 2025, the company serves frontier model laboratories and enterprises building their own systems.
