Plain offers an API-first platform that consolidates customer support channels—Slack, Microsoft Teams, Discord, chat, and email—into a single UI. It provides traditional help-desk functionality such as SLAs and response-time metrics while enabling internal collaboration across support, customer success, and engineering. The product is designed to let teams talk to customers wherever they are and to power multiple channels from one interface. Customers include Sanity, Laravel, Stytch, and Raycast. Plain was founded by Simon Rohrbach and Matt Vagni, who previously worked at Deliveroo. The startup recently raised funding and will use part of the capital to open its first U.S. office in San Francisco. Plain is a new startup building a customer support platform focused on real-time API integrations between a company’s product and its support interface. Its platform fetches live customer data from backends—such as subscription status, plan name and usage metrics—caches that data temporarily, and refetches when revisiting older tickets. Plain also enables highly customizable in-product support actions and interfaces, allowing developers to embed features like early access requests, product feedback flows and native contact forms instead of a standard chat widget. The company emphasizes a low-friction integration experience, saying getting started is as easy as building a Slackbot so development teams aren’t slowed down. Plain positions itself against incumbents like Intercom and Zendesk by prioritizing an API-first strategy to keep support context synchronized with product systems. The startup has raised seed capital to advance this approach and grow its product and integrations.
