We recently got featured on Betalist. It was a good listing and helped us grow our userbase by 200% over a day.
We applied for the listing through the Betalist website. And we had to wait for a few days for our listing to be considered and it finally went live.
We certainly advice checking Betalist out, might be a really good channel for growth for your startup too.
