With over 2,500 deep integrations, it has created a 'Workflow Moat' where users perform many tasks without leaving the app. This is fortified by a 'Cultural Moat'—playful UI and high-engagement features that distinguish it from legacy software. This 'Sticky Workspace' ensures a high-margin presence in the cores of technical organizations.
