Press Kit — Relay | USB-C 5G for MacBook

Overview

The pitch

Relay is a flush USB-C 5G module that gives any MacBook instant cellular connectivity. Plug it in, and within 3 seconds you're on 5G — no drivers to install, no hotspot to tether, no separate device to carry. Data is included out of the box.

Every other premium laptop — from Lenovo to Dell to Samsung — ships with optional 5G built in. Apple's entire MacBook lineup, including the new M5 Air, M5 Pro, and MacBook Neo, remains WiFi-only. Relay solves that gap with a $125 accessory that disappears into the port.

Relay is built by Kavin Lingham, 16, in Austin, TX, and was designed from scratch at Alpha School.

Age 16 · Austin, TX · Alpha School · @kavinaireal

Kavin is a 16-year-old hardware founder building Relay at Alpha School in Austin, Texas. He identified the MacBook 5G gap while watching other laptop makers ship cellular options Apple refuses to, and set out to build the accessory that fixes it. Kavin designs, prototypes, and markets Relay entirely on his own — handling engineering, industrial design, and business strategy simultaneously. Relay is his first hardware product.
