# Plain

> Plain is an API-first customer support platform built for B2B software companies. Instead of forcing teams into a rigid ticketing tool, it consolidates conversations from Slack, Microsoft Teams, Discord, email, chat and in-app forms into one workspace, layers customer data and AI on top, and exposes everything through a developer-friendly API. Founded in 2020 by ex-Deliveroo designers Simon Rohrbach and Matt Vagni, Plain positions itself as 'support infrastructure' - composable building blocks rather than a closed helpdesk - and is used by developer-focused companies like Sanity, Laravel, Stytch and Raycast.
