Meet The Team

Built on Science, yet Incredibly Human

We’re what happens when you mix together a bunch of computational linguists and ask them to solve tough language problems. Born out of the German Research Center for Artificial Intelligence, we’re passionate about language and technology.

We love language, we revel in its diversity, complexity and richness. Great language illuminates ideas, ignites imagination and delights the ear. Our software helps people create content that is more findable, readable and enjoyable – that’s our business.
