Vertical-specific platforms (Toptal for developers, 99designs for creative) capture high-value segments with specialized vetting and premium positioning
Direct hiring platforms and applicant tracking systems (Greenhouse, Lever) increasingly incorporate freelance management features, blurring category boundaries
