Structure
Hey Product Hunt! 👋
[1 sentence: what it is]
[2-3 sentences: why you built it / the problem you noticed]
[1-2 sentences: how it works / key differentiator]
[1 sentence: what's next / what you're looking for]
Would love to hear your thoughts — happy to answer any questions!
Example
Hey Product Hunt!
DataFlow turns raw SQL queries into visual dashboards in seconds.
As a data engineer, I was frustrated spending more time formatting
reports than actually analyzing data. Every BI tool I tried required
a PhD in their configuration. So I built DataFlow — paste your SQL,
get a dashboard.
It auto-detects chart types, handles large datasets, and exports
to PDF/PNG with one click.
We're offering 50% off the first year for PH users. Would love
your feedback — what reporting pain points do you have?
