Screening is the product
A firm buys a filter here more than it buys media. The value sits in what never reaches your intake desk: the caller outside the exposure window, the caller who already signed with someone, the caller whose diagnosis is not on your list. Your team writes those rules and we build the screener from them, then freeze it before launch so every call in a given week met one bar. Rule changes are versioned with the date they took effect, which is how a call from March gets read against March criteria and not against the ones you tightened in June.
