Strong ties are the people you know well and interact with regularly. Weak ties are people you know more lightly, such as a former colleague, an acquaintance from an event, or someone you met through a shared project. Both can make a network more valuable.
Strong ties often carry deep context and trust. Weak ties can connect you to people and information outside your usual circle. The point is not to rank one above the other. It is to recognize what each relationship actually offers.
Sociologist Mark Granovetter's research on the strength of weak ties helped explain how connections between different social circles can carry information. It is a useful idea for founders and sales teams, but it is not a formula for predicting which introduction will close a deal.
What strong ties can offer
A close colleague or advisor may understand your work, your strengths and the kind of conversation you are seeking. They can give candid feedback before you make an ask, and they may be comfortable explaining your work to someone else.
That does not mean they know everyone you want to meet. A strong relationship is valuable even when it is not an introduction path.
What weak ties can reveal
A former classmate or occasional collaborator may spend time in a different industry or community. They might offer a perspective you have not heard, point you toward an event, or know someone relevant to your goal.
But a LinkedIn connection or old email is not proof that a person is ready to help. Begin by reconnecting and learning what they are working on now.
A simple network reflection
| Relationship | What you know | What you could do next |
|---|---|---|
| Close advisor | Understands your business and your current challenge | Ask for candid feedback on your target list. |
| Former colleague | Knows an industry you want to learn about | Reconnect and ask what has changed in their work. |
| Event acquaintance | Shared a useful conversation | Follow up on the topic you discussed. |
These are illustrative examples. The right action depends on the relationship, not a label.
Put both kinds of ties to work
For an upcoming raise, ask a close advisor to challenge your investor-fit criteria. Then reconnect with a former colleague in a different ecosystem to learn what you may have missed. One conversation gives depth; the other may bring a fresh perspective. Neither person owes an introduction.

Share only information you are authorized to use, and review the result before acting.
Help me review the relationships around [goal].
Here are the people and the context I actually know: [notes].
Suggest who might offer candid feedback, who might bring a different perspective and a natural next step for each.
Know the context before the ask
Finta Networks can show available relationship evidence from connected sources. Use it to remember context and explore possible paths, then rely on human judgment to decide whether a conversation or introduction is appropriate. A relationship score is a clue, not a measure of someone's willingness to help.
