WarmStars started from one idea: the star count on a repo is really a list of developers who chose to pay attention to your work, and almost everyone lets that signal go to waste. We turn the number back into the named people behind it, so builders can reach the ones who already raised their hand, without buying a cold list of strangers.
Most sales tooling points you at strangers. You buy a list, guess at fit, and hope. The developers who starred your repo are the opposite: they went looking, found your project, and flagged it. That is the warmest first line you can write, and it was sitting in plain sight.
WarmStars exists to make that list usable and to do it in a way we are not embarrassed by: public data, an easy opt-out, and no send button. We hand you clean research and get out of the way.
We read what developers have already chosen to make public on GitHub. We never guess an address, and we never identify a person by their display name alone.
A built-in do-not-contact list is matched by email and GitHub login at every source. Anyone can remove themselves once and stay out of every future scan.
WarmStars gives you research, not a send button. You decide who to contact and send from your own tools, so you stay in control and responsible for lawful outreach.
A public email exists for roughly 30 to 50 percent of a repo’s stargazers, and we say so. Everyone else is still a named profile, with a confidence tier on every email.
The specifics live in our privacy policy and terms. Anyone can remove themselves at warmstars.com/legal/opt-out.
