The ironic thing about this is that you have to have product/market fit for people to recommend the product to other people. Consider every case (there aren't many) where this strategy was successful.

This does seem to work sometimes in the case of e.g. Kickstarter, but less than half of kickstarter projects reach their funding goals so it's not a great example.
