What a Relationship Strength Score Actually Measures
November 23, 2026 · 4 min read · LeadLex Editorial
A relationship strength score is a number, usually between zero and one hundred, that purports to tell a partner how strong her relationship with a given contact is. Inside LeadLex, Lexi maintains a version of this score for every contact she watches. We are sometimes asked what it actually measures, and — more important — what it does not.
What goes into the number
The score is a weighted composite of observable signals. The exact weights move as we learn what predicts retention and expansion in IP work specifically, but the inputs are stable.
Meeting frequency. How often the partner and the contact actually meet, in person or by video. Calendar data, not self-reported.
Response cadence. Median time to reply on both sides of the conversation. Long, slow turnaround in either direction is a degradation signal. A relationship where the contact replies in twenty minutes is structurally different from one where she replies in four days.
Recency. When the last substantive exchange occurred. A high-frequency relationship that stopped six months ago is a different shape than a low-frequency relationship that touched last week.
Mutual contacts. How many people inside the contact's organization the partner also corresponds with. A relationship that exists only with one inside counsel is more fragile than one that runs across three.
Prior matter history. Volume and recency of billable work for the contact's organization, weighted by matter type. A patent prosecution relationship with steady file flow scores differently from a single past litigation that closed three years ago.
Message tone signals. Coarse-grained read of how the conversation is going. Short, transactional, formal language over a long arc differs from longer, warmer exchanges. We are deliberately conservative here; tone is the easiest signal to misread.
What the score does well
The score is most useful at the edges. A contact who has historically been strong and is now degrading on three or four of the inputs is exactly the dormant account a partner needs surfaced. The number compresses what would otherwise be a tedious manual review across dozens of relationships.
It is also useful for triage. Of the four hundred contacts inside an IP boutique's combined book, the partner cannot personally track all of them. The score answers the question "which thirty should I look at this week?" with reasonable fidelity.
What the score does not measure
The number does not know what the partner knows. It does not know that the contact is about to leave her general counsel role for a chief legal officer position at a larger company, because the contact mentioned it over coffee and the partner has not put it anywhere a system can read it. It does not know that the last matter ended badly for reasons that did not show up in the billing — a difficult inventor, a missed deadline that was not the firm's fault but felt like it. It does not know that the contact's company is being acquired and the relationship is about to be redefined.
It also does not measure trajectory in the way a partner intuitively does. The partner can tell, in a five-minute call, whether the relationship is warming or cooling. The score reflects past behavior and lags the partner's read by weeks.
How to use it without over-relying on it
The score should be an input to the partner's judgment, not a substitute for it. When the system surfaces a contact as degrading, the right reaction is not "the relationship is in trouble" but "is the relationship in trouble — what does the partner know that the system does not?"
We have built Lexi to present the score with its components visible. A partner can see that the number dropped because response cadence slowed, or because a mutual contact left the organization, or because the last matter closed eighteen months ago. The transparency lets the partner override the number when she knows something it does not.
The right discipline is to use the score to set the queue and use judgment to set the action. Lexi surfaces the contact. The partner decides whether to call.
