Outlook540Your address book knows names. Happenstance knows people.
Search by role, not name
Describe the person you need and find them, even when you've forgotten what they're called: "lawyers in my network who work with startups" just works.
Every contact, enriched
Each saved contact is matched to their professional profile with a current role and company. The person you saved as a student five years ago shows up as the founder they are now.
Duplicates become one person
The same person in your contacts, your inbox, and your LinkedIn merges into a single profile with everything you know about them in one place.
What Happenstance users say
“Happenstance is by far the best social network search I have ever seen.”
Private and secure
You control what you share. Your public profile shows a constellation of named people you know by default, which you can turn off anytime, and your data is never used to train AI models.
