What is Grapevine’a business model?

You are. Get users and dau till they can pivot to a useful monetised use case?

The stalker companies will pay top dollar to keep a check on their disobedient employees who talk smack on web platforms.

One, for sure, is data monetisation.

Get users, wait , then: Cross sell stuff - job portal, insurance, lending, etc Haven't seen ads yet, but maybe in the pipeline.
