How do I market my MVP?

I am creating a software solution (mobile app+web app) which can help a small group of any and friends group to create a workspace(similar to slack) and then create events and they will be able to create tasks for those events and can also chat with people in the same workspace. So basically a (jira+slack) for non organisation peeps. I started creating this two months back, and a basic MVP will be completed by the end of april. I want to know from you people "The Product managers" how can I do marketing for this solution, can't promote it on my personal linkedin as my company is not okay with their employee working on side peoject
