TL;DR
25 subreddits split into 4 categories: launch communities (where you can showcase), feedback communities (where you get honest input), B2B audience communities (where your customers hang out), and growth communities (where you learn tactics). Different communities for different stages of your startup.

These subreddits explicitly welcome product showcases. Use them for launches, beta signups, and early traction.
