I was talking to a friend from work who is extremely active on Grapevine and they told me about this new feature on the app.
Apparently, if you are active on Grapevine everyday for 30 days and make 1000 grapes during that time then you get a bottom card asking you to opt in to a more exclusive community of professionals.
All of them meet on a monthly basis across the country, for a fireside chat. Everyone is flown from their base locations and the entire thing end to end is sponsored by Grapevine where you spend no money.
I am extremely certain because I have seen their Instagram stories.
