I built and ran a groupware/crm system from 2001 to 2009. But didn't get the traction I needed and couldn't afford the co-located hosting any longer. I spent 3 years developing it full-time myself and very part time on it the rest of the time. While also supporting a wife and two kids. I moved it to very cheap hosting, told everyone it was closing, but then never closed it but didn't accept new signups. Checking now there is still a little usage in 2019 (although the majority of usage stopped in 2016). It costs me $20 to keep alive, using GoDaddy. It was $14 a month but GoDaddy keeps raising their hosting price with no notification. Eventually I will re-design the UI to Boostrap to make it modern and relaunch it. What I am trying to say is if you made something nice that you like, you can keep it alive and work on it sometime in the future. You never know when Slack is going to bought out and then eventually die. You could be the DuckDuckGo to Google but for Slack. If you had a million dollar marketing budget things would be different.
