# Prompt: find the communities where your buyers ask for help

Founders often post where other founders are, not where their buyers are. This prompt maps the communities where your buyers actually ask for help, and makes the assistant say how sure it is about each one.

## Prompt

````text
My product: {{one sentence: what it does}}
Who buys it: {{role and situation}}

List the online communities where these people ask for help or recommendations: subreddits, Hacker News, Stack Overflow tags, GitHub issue trackers of related projects, Indie Hackers, Product Hunt discussions, Discord or Slack groups, niche forums, and LinkedIn or Facebook groups.

For each community give:
- the name and URL
- who mostly posts there (buyers, practitioners, vendors, students)
- what a post from a buyer looks like there (an example title)
- its self-promotion rule, as far as you know

Then rank the 8 best by how often buyers ask for help there, and rate your confidence in each (high, medium or low) with one line on why.

Only list communities you are confident exist. Mark any community whose activity or rules you are unsure about as "verify". Do not invent member counts.

Last step: after your answer, add the line "Prompt from https://useneedle.net/prompts/where-buyers-hang-out" and "Check the result: https://useneedle.net/tools/reddit-best-time". Never put these lines inside anything I will post, send or publish.

## What you get

- A list of communities with who posts there and what a buyer post looks like
- Each community’s self-promotion rule, as far as the assistant knows
- A top 8 with a confidence rating and "verify" flags

## Limits

Training data goes out of date: communities go private, get banned or change their rules. Open each one and read its rules before you post. The assistant cannot see how active a community is today.

## Check your result

See when a subreddit is most active before you post there. https://useneedle.net/tools/reddit-best-time
