While it does seem like they're doing well and they have gotten some very nice backing from the NYT, I would also like to know what their revenue is. They throw out the number of users everywhere, but they don't mention the important numbers like how many are actually paying and how many are paying with regularity. It just feels like they're hiding behind a high user number.

It's two years old and has half a million users in a country of 16 million people? Although it's recently expanded to Germany and growing really quickly there too, so that might skew the percentage a bit.

Back in 2014, when they had 100,000 users, roughly 20% was a paying customer.
