I am already working on https://coco.so for some months and some days ago wrote a tweet putting it out in the world. With just this one tweet I got 150 people to sign up for the waitlist.
The different photos and tagging people that inspired me helped a lot. I thought that people are interested in stories and not so much products.
So now off to grow this waitlist every week :)
Here's the tweet: https://twitter.com/dennismuellr/status/1216105977289879553
