I'm staggered that there are 575 companies paying slack $100k / year. I don't even have anything against slack but what is possibly worth $100k a year from a comms software?
My company pays quite a bit for slack and an alerts integration. My company spends ~$500k/day in client’s money and so real-time alerts in slack easily pay for themselves.
Basically you can write SQL and if there are results, we'll send a message to Slack. Same works for Python, including plots / images.
