Growth Collective is a platform that helps clients hire pre-vetted marketing talent with experience at the world's leading brands. Its team uses Stacker to facilitate work among its freelancers, clients, and partners.

Since Growth Collective started using Stacker with their clients, they've expanded to using it throughout its business. Clients have a Stacker portal to view and schedule time with matches, freelancers have a Stacker portal to edit their profile and view their matches, and external partners—like the company's accountant—have Stacker portals configured to only display relevant data to their jobs.
