The language of relationships.

Cold outreach is contacting someone you have no prior relationship with — the opposite of a warm introduction.

A dormant tie is a relationship that's gone quiet — someone you used to be in touch with but haven't connected with in a long time.

A double opt-in intro is when the connector asks both people's permission before making an introduction, so neither is surprised.

Dunbar's number is the idea that humans can maintain about 150 stable relationships at once — a cognitive ceiling on your active network.

A follow-up cadence is how often you reach out to someone to keep the relationship warm — tiered by how close you are.

Introduction etiquette is the set of unwritten rules for making and asking for introductions politely and effectively.

Network mapping is visualizing who you know and how they connect — turning a flat contact list into a graph of relationships.

A personal CRM is a tool for managing your own relationships — the people you meet, what you talked about, and when to follow up — rather than a company's sales pipeline.

Reciprocity is the social norm of returning a favor — the give-and-take that keeps relationships balanced and healthy.

Relationship capital is the trust and goodwill you've built with the people in your network — an asset you can draw on, and that depletes if neglected.

Relationship management is the practice of deliberately maintaining and growing your personal and professional relationships over time.

A touchpoint is any meaningful interaction with someone in your network — a message, a call, a coffee, a comment.

A warm introduction is being connected to someone by a mutual contact who vouches for you, rather than reaching out cold.
