Any nice slack bots for startups out there?

We are a small team 8 people. And we want to stay somewhat small. 20-30 max 😅. Today we use google analytics slack bot to keep the team updated on our growth and GitHub slack bot to make sure the devs work on the weekends 😬 (that would be me). What are you slack bots are using in your startup? Any tips? Thank you 🙏
