Contacts in common
See who in the group knows the same people you do. Each contact appears under the name you saved in your own list.
For business groups
Your next client is already in the contacts of someone in your group.
incomum.net cross-references the members' contacts, shows who knows whom and turns every contact in common into an introduction request, without exposing anyone's data.
Access by invitation from your group's administrator.
Contacts in common
You and Marina know 3 people
Ask for an introduction
- Encrypted phone numbers and emails
- Matching only within your group
- Contact import from .vcf
- Single-use invitations, valid for 7 days
Your group knows thousands of people. Nobody knows who knows whom.
At every meeting someone asks: “does anyone here know the director of company X?”. The answer depends on who was in the room and who remembered in time.
incomum.net answers that question before the meeting. Each member imports their own contacts, the platform finds the matches within the group, and you arrive already knowing who can introduce you.
An introduction from someone trusted opens doors that a cold message rarely does.
How it works
From invitation to introduction, in five steps.
-
1
Get your invitation
Your group's administrator sends an invitation to your email. You choose your password and sign in.
-
2
Import your contacts
Upload the .vcf file exported from your phone or add contacts by hand. Importing again updates without duplicating.
-
3
Discover what you have in common
See who in your group knows the same people you do and which members have the most connections.
-

Ask for the introduction
Explain who you want to meet and why. The member receives the request and decides whether to accept.

Follow it until it happens
Each request shows whether it's pending, accepted, declined or done, with a notification at every change.

Privacy
Your contacts remain yours.
Phone numbers, emails and notes are encrypted in the database. To find matches, the platform compares codes derived from that data, not the data itself.
Administrators handle members and invitations, without access to private contact lists.
What the group sees

- The contact under the name they saved themselves
- The introduction requests sent to them

Frequently asked questions
Before you join.
What is incomum.net?
It's a platform for business and networking groups. Each member imports their own contacts, the platform shows which contacts the group's members have in common, and lets you ask whoever knows the person for an introduction.
How do I join incomum.net?
By invitation. Your group's administrator sends a link to your email. The link is valid for seven days, can only be used once and can be revoked.
Can other members see my contacts?
No. They only see that you share a contact, under the name they saved themselves. Your phone numbers, emails, notes and unmatched contacts stay with you.
Does a contact in common guarantee an introduction?
No. A match helps start the conversation, but it doesn't prove a close relationship. That's why each request explains the goal and the member chooses whether to accept.
Which contact files can I import?
.vcf files, the format exported by phones and the main contact services, with up to 10 MB and 5,000 contacts each. You can also add contacts manually.
Can I delete my contacts?
Yes, at any time, from the dashboard. When you delete a contact, the connections and requests linked to it are removed too.
Can the group's administrator see my contacts?
No. Administrators manage members and invitations, but have no access to private contact lists.
You already have something in common with your group.
