Catch a relationship before it goes cold
Half-life decays 50% every 90 days without contact. The zone view surfaces the yellow contacts you still have time to save, not just the red ones you already lost.
Relationship OS
See which LinkedIn relationshipsare going cold — before they are gone.
Import your connections once. Half-life decay scoring, a reciprocity ledger, and vouch scores turn a static contact list into a network you actually work.

What it is for
A contact list does not tell you who to call.
Know who you can ask, and who you owe
The reciprocity ledger tracks intros, referrals, and advice both ways. Ask for a favour when the balance is in your favour; offer one when it is not.
Vouch without staking your reputation on a guess
Rate your own read on competence, character, and connection quality — a private note, not an AI judgment of anyone. When someone asks for an intro, you already know whether you can give a strong one.
How it works
CSV to working list in three steps.
Step 1
Import your connections
Upload the Connections CSV LinkedIn exports for you. Contacts, companies, and connection dates come across in one pass.
Step 2
Log interactions as they happen
A call, a comment, an intro — each one refreshes the half-life score and updates the reciprocity balance.
Step 3
Work the list
Sort by coldest, filter to the yellow zone, and get AI-drafted reconnection openers grounded in the contact’s recent company news.
Import the list. Work the network.
Bring your LinkedIn connections in and see the cold ones first.
