* I made the bot for my startup [0]. It supports interactive messages (buttons, dropdowns), slash commands, and @ commands. Put another way, I use (and have knowledge of) pretty much all parts of the Slack API.
* You're getting a backend with the bot. This backend could just save stuff into a database or do more sophisticated things.
* I'm happy to work with the non-profit, ScriptEd, on some content marketing material so that the person or company that sponsors this gets public recognition.
* Timing - I'm doing this in tandem with other things. Obviously depends on what I get but let's say roughly 2 months.
* We're pretty close to getting our startup's app in the app store. I'm happy to help with this process now that I'm more familiar with it.
