I'm clearly bias, but our (https://seekwell.io/) Slack bot is pretty awesome. It lets you send alerts from your database with just a few lines of SQL (e.g. get an alert when a user upgrades or cancels). It's super flexible, any SQL you can dream up can be turned into a Slack alert in minutes.

Here's a 90 second demo which also covers our Google Sheets integrations https://www.loom.com/share/256e83c925744ad9977e109b3dfd9c6d

This is one of the best ways to encourage a culture of appreciation. It's fun and easy to understand.

Living up to its name, greetbot welcomes all new members to a slack workplace with a personalized message and can handle a variety of different tasks. We use the bot to give new users an overview of the different public channels and what each of them are used for. Nothing big but a fun little add-on.

My former team at Zapier used Donut in Slack to make remote work a bit less lonely. The idea is, Donut randomly pairs up everyone in the company each week and starts a new DM conversation between you and the person it picked for you this week. That way, you could get to know other people on the team in a quick chat conversation, over a call, or perhaps schedule lunch together or something if you're in the same area. Tiny thing that helped you get to know people across the company especially in a fast-growing team.

I'm a pretty big fan of GeekBot (https://geekbot.com) for daily standup that way our whole team knows what everyone is working on, whether they're remote or in-office.

All answers go into a specific Slack channel so everyone can easily see.
