What Linq is
Linq is messaging infrastructure for agents. One API to reach people on native iPhone messaging, Slack, WhatsApp, SMS, and RCS. The apps they already use and love.
The interface for software is collapsing back into a conversation, and someone has to run the rails underneath it.
We are the only SOC 2 Type II–certified native iPhone messaging API in existence. Your messages are encrypted and inaccessible to us. Over 1000 teams have sent 150M+ messages on Linq.
Things we'd love to see
A Coinbase wallet you can text
Send a friend $10, check a balance, or get told when a price moves via text.
Coinbase CDP docsA Shopify shopping assistant
Browse a store, build a cart and check out without leaving the conversation. The Storefront API is public, so a real storefront is a few calls away.
Shopify Storefront APIA Spotify music agent
Queue something for the gym, get a playlist built from a sentence, or find out what a friend has had on repeat.
Spotify Web APIA Ticketmaster watcher

Ticketmaster Discovery APIAn Oura recovery coach
Pull sleep and readiness every morning and text back the session that actually fits the day.
