Sample card with made-up details
Anyone with the link sees the website, LinkedIn and booking link.
Sign in with Cincio.
A login button that sits next to Google and Apple, backed by a card people keep current themselves. Apps ask; the person ticks what to share. Verified email, verified phone and a confirmed role at a company, never more than they allow.

The directory of who's who.
Search people and organisations. Open a company, see who runs it, and send its CEO a connect request. Organisations build their people directory once; every person keeps their own card and chooses whether to be listed.
Three products that make each other better.
Point tools each hold a slice of you. Cincio holds one card, kept current by the person it describes, and every part of the product reads from it.
An org lists its team
Admins add people once. Each person claims their card by verifying their own email or phone.
People find people
The directory shows who works where. A connect request opens the full card when accepted.
The card goes everywhere
One link and QR code for every bio, signature and intro. Update once, current everywhere.
Apps sign people in
Sign in with Cincio carries verified details and confirmed roles, so new apps start with trust.
Numbers and emails stay hidden until you choose who sees them.
Leave a company and it removes the listing. Your card stays yours.
Card details never go to analytics or advertisers.
Download everything on your card, or delete it, whenever you like.
Make your card. It takes a minute.
Your name, one link, one way to reach you. Add your company and your team when you are ready.
