Best subreddits for e-commerce founders
For e-commerce the operator rooms are r/ecommerce and platform-specific homes like r/shopify, r/FulfillmentByAmazon, and r/Etsy. If you sell tooling to store owners, these are your buyers comparing options in public.
These communities are pitched at constantly, so their spam radar is sharp. The operators who win answer platform questions with specifics (fees, settings, screenshots) and let their product show up in their profile, not the post.
The communities
| Subreddit | Members | How to use it |
|---|---|---|
| r/ecommerce | 666k | Store operators across every platform. Tool questions come up daily; answers with numbers win them. |
| r/shopify | 370k | Shopify merchants. App developers: support threads beat launch posts, every time. |
| r/dropship | 357k | Dropshipping operators. High promo pressure. Legitimate expertise stands out sharply. |
| r/Etsy | 316k | Makers and shop owners. Craft-adjacent tools find real users here. |
| r/FulfillmentByAmazon | 143k | Amazon FBA sellers. Deeply operational: fee math and logistics answers earn trust. |
| r/AmazonSeller | 97k | The other Amazon operator room. Same rules: specifics or silence. |
