What means of communication do companies/startups use?

Question

Messengers

I'm wondering if I decided to create my own startup and I have a certain number of employees, moreover, some of them work directly with me in the office, and the other are freelancers. Well, it’s inconvenient to keep in touch with each one separately, but you need to set tasks and preferably without leaving your office + so that you can visually see what tasks have been completed and how the execution process is going.
Are there any messengers combined with task managers?
If so, which ones are used by startups, which large companies?

Answer 1

Use Slack and connect whatever extensions you like: Trello, Jira, etc..

Answer 2

And we use tada.team . There is both a messenger and a task book in one “face”.
You can set a task directly from the message, wildly convenient.

Answer 3

Startups are no different in this regard. Integrating chats with a task manager is wild and useless: it’s not convenient, it doesn’t work.
There will never be one communication channel with freelancers - do not confuse with outsourcers. And your task manager didn’t give up on them either.
Depending on what process in the company, there can be anything: from trello to redmine and jira
