Feedback needed on what to do next

Hey fellow indie hackers,

I was thinking for a while about remote work and how could I come up with something that can bring value to remote teams. Then I realised that most of the remote teams over there are probably communicating through slack. So, I started working on a slack app and build an MVP. Now, I don't know what to do next: continue working on improving the MVP or building a landing page and start gathering some interested folks?

Any feedback is much appreciated!

Thanks
