Contentful provides content infrastructure for digital teams to power websites, apps, and devices. Unlike a CMS, Contentful was built to integrate with the modern software stack. It offers a central hub for structured content, powerful management and delivery APIs, and a customizable web app that enables developers and content creators to ship their products faster. Companies including Spotify, Red Bull, WeWork, Lyft, and Urban Outfitters rely on Contentful to manage content as part of their modern web stack.

Contentful is growing rapidly, backed by $80 million in funding from VC firms including Benchmark and General Catalyst, and strategic investors including Sapphire Ventures (SAP) and Salesforce Ventures.

We’re a fun team of more than 200 people from 44 nations, with offices in Berlin and San Francisco. Join us!
