When was r/cofounder created?
r/cofounder was founded in February 2012 and is a public — anyone can post community. Age matters: an older community with steady growth has survived Reddit's moderation churn; a young one with a spike may not.
Who posts in r/cofounder?

Can I promote my product in r/cofounder?
We don't have a promo-tolerance read for r/cofounder yet. Default to the safe approach: read the sidebar rules, contribute in threads where you gain nothing, and mention your product only when it is the honest answer to someone's question.
How do I monitor r/cofounder for mentions?
Hit Watch on this page. Prowlo starts crawling r/cofounder into your Dataset — every new post indexed and embedded, searchable semantically, queryable by your AI agent over MCP, and able to trigger keyword alerts in Slack. Prowlo is read-only; it never posts on your behalf.
