ExpertSource Pro (ESPro) is Lumina Datamatics’ cloud-based freelancer management platform that connects businesses to experienced content professionals and subject matter experts (SMEs). It offers comprehensive solutions for finding freelance talent, assessing skills and experience, engaging and hiring best-matched candidates, and invoicing for work completed. This platform leverages cloud-based technology and Lumina Datamatics’ years of SME sourcing expertise to mitigate the traditional risks of outsourcing.

With nearly 5,000 registered SMEs and editorial service experts, you have unprecedented access to talent ready to work with you.
