Playbook: Case-Study Lookalikes (filter mining, not raw lookalike)
All rules here are best practice, not law. Override any of them when the campaign calls for it; note the best practice once and move on.
Use when: a client has a case study, a flagship logo, or one obviously happy customer, and you want the list of companies for whom that story is the strongest thing you could say.
Do not use when: you are building a whole market from an ICP sentence with no standout customer
to anchor on; or you want to name a customer off the prospect's own case-study page ("saw your
work with Intercom") — that is the opposite direction and belongs to playbook-case-study-page.
See also disco-like in this repo for plain seed-domain lookalike discovery. This playbook is the
higher-precision version: it mines why the story resonates before it searches.
One-line output: case_study_ref = "attentive" with
lookalike_case_study_line = "a marketing platform about your size".
