I created Multy 5 years ago. Thanks to a post on HN at that time, it was a small success (https://news.ycombinator.com/item?id=25870504)

Since then, I continue to maintain the website and I have around 50k lists, 8k users, and around 400€ MRR (ads and subscriptions).

I'd love to see more users, but I'm glad of what I did with multy !
