New subdomain appeared

A company launches a new subdomain such as docs, community, partners, status, or app.

Subdomains show what a company is building before it announces it. A new docs or developer site means an API launch, a community site means a community program, and an app subdomain often means a new product.

How we detect it

Runs on Claude Code, Apify, crt.sh, and Clay.

  1. Monitor certificate transparency logs and DNS for new subdomains across your accounts.
  2. Sort them by type, and visit each one to see what it is for.

What it triggers

An opening line, to show the angle. It never goes out as written.

Community programs usually get their first 500 members easily and stall at 2,000. If you’re building one, we can share what moved it for others.
  • Content: Share material on the project the subdomain points to.
  • Ad audience: Add the account to an audience for that topic.

Where it goes wrong

  • Mentioning the subdomain before it is public. Wait for a launch or a link.

A second signal on the same account moves it up.
