The company operates a two-sided marketplace connecting a global workforce of more than 8 million registered Clickworkers across 136 countries with businesses requiring human-generated or human-validated data. Since December 2024, clickworker has operated as a wholly-owned subsidiary of LXT AI Inc., a Canadian AI data solutions provider headquartered in Mississauga, Ontario.
The platform architecture consists of a customer-facing Marketplace (marketplace.clickworker.com) for project configuration and results retrieval, a worker-facing Workplace platform, dedicated iOS and Android mobile applications, a programmatic REST API for automated workflows, and an iFrame-based external form embedding option. Core product lines include AI Training Data Services (image, video, audio, and text annotation for machine learning pipelines), Survey Services (including a self-service survey platform launched June 2026 with access to a 10M+ contributor panel), Store Check Services (display audits and mystery shopping), Tagging Services (product categorization, color tagging, sentiment and feedback analysis), Crowdtesting Services (app, website, and game testing), List Building (email and price research), and SEO Services (copywriting and traffic generation). The platform supports three delivery models: Managed Service for full-service enterprise engagements, Self-Service for direct client configuration, and Crowd-as-a-Service for on-demand workforce access.
clickworker monetizes through transaction fees on microtask completion, a 40% take rate on self-service survey responses, project-based managed-service contracts typically negotiated on multi-year terms, and usage-based or subscription pricing for API access. Customers span AI and data science teams, market research firms, eCommerce and retail platforms, and digital marketing groups, with named enterprise clients including OTTO, Bosch, Tennis-Point, and Axzo. The platform is ISO 27001 certified and GDPR compliant, addressing data security and privacy requirements for regulated enterprise buyers across Europe and North America.
