I'd argue it's more about service or API integration.

People are willing to pay for solid solutions as long as you can add value

For instance, let's say PagerDuty did not have Slack integration. If you decide to build the glue that connects both you already have a ton of potential clients as they don't want to invest money themselves etc.

If you're trying to get a `worse than zulip` experience but really like threads then your only option is a paid bot called Smithy: https://smithy.app

So at least someone is making money from bots.

Slack workflows are pretty powerful, and there is definitely a gap in available actions (steps).

I'm working on a Slack bot that I'm hoping to monetize.

I'd pay for a slack bot that detects which of the channels I've been involuntarily added to has messages from bots and proactively mutes them for me.
