By connecting work management tools, they allow managers, cross-functional teams, departments, and entire companies to benefit from seamlesscollaboration and improved communication. The app syncs projects across a number of tools like Trello, Asana, JIRA, GitHub, Wrike, Zendesk & Hubspot. This is a hard problem of semantics, synchronization, and APIs. | $20M / Series B / Oct 26, 2022 | ||
