If you’ve ever used Go before, the concepts of Publish/Subscribe should be fairly familiar to you. It is much like how goroutines communicate over channels between each other, the idea boils down to allowing for such a channel to have multiple ‘subscribers’ receive messages sent on the channel. This paradigm can be powerful when used right, allowing for a cut down of complexity from both the publisher and subscriber side, as well as fast asynchronous communication.

When I joined Ably we were a team of 13 people in an office in Camden. We weren’t long off the back of securing our Series A round, we knew lots of hiring was coming, and we needed to grow up (a bit). The culture was easily absorbed by osmosis: very welcoming, smart people, like to have a pint in the Hawley Arms. No set working hours. Lots of dogs! It’s bewildering to think how much can change in that time.
