Any Slack/Discord groups for mobile app builders (10k+ MAU)?

Hey builders 👋

I'm building a plug-and-play loyalty & gamification engine (+ an optional tokenization layer) for mobile apps

Currently doing research on how folks approach activation & retention.

Does anyone know good communities where growth folks or PMs from fintech, edtech, or productivity apps (10k+ MAU) hang out?

Could be Slack groups, Discords, forums, etc. Appreciate the help 🙌
