| Communities where your customer already is | Almost every first launch. Subreddits, Slack and Discord groups, industry forums, Facebook groups. | A week of being useful first; a post that leads with the problem, not the product. | Your first ten to fifty users. The best channel by far for niche products. |
| Your beta users and interviewees | Products that came out of validation. | A personal message to each, asking for one specific thing: a share, a review, a referral. | Small numbers, high quality. These are the people who refer others. |
| Product Hunt and similar launch sites | Tools for people who work in tech or startups. | A clear tagline, five screenshots, a first comment that tells the story, friends ready to comment early. | A spike of curious visitors, few of whom are your customer. Useful for feedback and a badge, rarely for revenue. |
| A personal post on LinkedIn or X | Anything; it costs nothing. | The story of why you built it, with one screenshot. Not a feature list. | Depends on your network. Reposts from people in the industry matter more than likes. |
| Email to a list you built during validation | Products that ran a landing-page test. | Three short emails: it is live, what people are saying, last chance for the launch price. | Your best conversion rate of any channel, if the list is real. |
| Paid ads on day one | Almost nothing. | Do not. You do not yet know which message works. | Money spent learning what the free channels would have taught you. |
| Press | Products with a genuinely new angle or a local story. | A short, specific pitch to five named journalists who cover your niche. | Usually silence; occasionally a piece that outperforms everything else. Low cost to try. |
