Port by Numberless provides a messaging platform that lets users connect without sharing phone numbers, email addresses, or usernames, giving them full control over who can contact them. Users can create shareable links or QR codes for safe discoverability, customize chat permissions per contact, and instantly disconnect unwanted connections, reducing spam and protecting personal data.

Problem
Traditional messaging apps require users to share personal identifiers such as phone numbers, email addresses, or usernames, exposing them to spam, scams, and unwanted contact. This reliance on persistent identifiers makes it difficult to control who can reach you and to disconnect from unwanted conversations.
Solution
Port provides a privacy‑first communication platform that eliminates the need for any personal identifiers. Users create unique links or QR codes that can be shared to initiate a conversation, allowing contacts to connect without ever seeing a phone number or email address. Each chat can be customized with granular permissions—controlling who may message, call, view the profile, or share contact information. The platform records the source of each connection, and a single “disconnect” action permanently blocks the contact from reaching the user again. All messages and media are protected with end‑to‑end encryption, and the underlying Port Protocol handles authentication to prevent impersonation.
Target Audience
Port is aimed at privacy‑concerned individuals, professionals, and businesses that want secure, identifier‑free communication and fine‑grained control over each contact.
