Erin C.Sales TrainingFinancial Services, 51-200 employees

"I primarily train new employees to use the software and once you get the hang of it everything is fairly intuitive."

Josh H.Transportation ManagerChemicals, 11-50 employees

"Some of the integration was taxing, and on rare occasions calls are dropped when I am out of the building."

Cristiano F.ConsultantMarketing and Advertising, Self-Employed

"The platform is flexible enough to support a wide variety of workflows and integrates seamlessly with many business tools. While managing notifications and information flow can sometimes be challenging in larger workspaces, the productivity and collaboration benefits far outweigh these limitations."

Arthi R.EngineerAccounting, 1001-5000 employees

"Its free plan has limited message history and integrations. While it’s great for real-time chat, Slack isn’t ideal for long-form discussions or detailed project management."
