Why do companies move away from freelance platforms?

Regardless of tier, freelance platforms share the same structural limits. You hire an individual, not a team, so management, code review, and QA stay with you. You pay either stacked marketplace fees, as on Upwork, or an embedded markup, as on Toptal and Turing. And a single freelancer is a single point of failure, so an absence or a departure stalls your roadmap. For ongoing or business critical work, companies increasingly want a team, delivery accountability, and transparent pricing instead.
