At the Open Innovation team at Mozilla, I learned about Donutbot. It is a Slack bot that randomly matches people from the team to each other, so that they can then go on and enjoy donut together. They are usually just metaphorical donuts, you could totally go for bubble tea or lunch. It doesn’t even have to be together, in person. You could use video conferencing software. But if you do meet IRL, selfie-sharing is appreciated.
