I’ll stick to my earlier recommendation -

Main value is in “building a network” into the product.
An example of a “survey” product that did that and scaled up (becoming a public company) and another company that implemented the same feature and also scaled up to millions of users - is
Kahoot.com
Basically, the “network” feature is one that other users on your platform can share something that other users can use/see. Low value things are like “leaderboard scoreboards” but the high value ones would be “creating a survey that other people can also use” which then leads to “users creating surveys for reselling to other users” which then creates an economy/marketplace within your app.
Read the book Cold Start Problem to learn more, it also tells a good origin story of Slack, this tool we are using, on how it got sticky.
