It's a great exercise to do, also for designers
A tool to help lawyers more quickly organize class action lawsuits — I know this sounds kind of controversial, but there’s probably hundreds of millions of dollars to be made here. Lawyers currently send out thousands of letters to get people involved and this could all be done online.
Automatic referral tracking through URL — this one is kind of technical, but every page on a product should append a unique parameter (something like ?id=532391) that way when I copy the URL and send it to a friend, they know who referred who. And a link could be permanently created between users.
A marketplace for airline tickets — this is a hard one, because you’ll have to get around a lot of airline industry regulation, but anyone who can crack it will be very successful. It’s amazing to me that if I can’t make a flight, I can’t sell my ticket to someone else.
A tool to help online services onboard users better — most products have pretty horrible onboarding flows (the steps after a users signs up) that aren’t being tested or optimized. There are a few services out there that do this, but none that have really stood out to me.
GPS has 4+ billion users and is still operated by only 40 engineers, or 1 engineer per 100 million people (!)

Only accepts wechat pay. And you can only order with their wechat mini app.
It has been very hard to pay for things without wechat pay. Incredible how much things have changed since last here.
And wechat pay is only available to people that connect a Chinese bank card. The country runs on a fully KYC digital payment rail.
a few more data points:
- plenty of places accept cash but virtually every time they have asked can we use wechat instead? - some accept cash so infrequently they are literally carrying no cash to make change. had to run to a store to make change for my cab driver
