Every year, CSA Research (formerly known as Common Sense Advisory) releases a list of the Top 100 Language Service Providers in the U.S. We feel very lucky to be included as a top interpretation company on this list, but there are several others alongside us that you should know — especially if you’re on the hunt for the perfect language service provider (LSP). 

One thing about the language industry: It’s huge. Huge. Our CEO likes to say that we’re the “biggest little industry nobody’s ever heard of.” It encompasses much more than remote interpretation, too, like translation, localization, and transcription. 

So while there are plenty of heavy hitters in the U.S. language services industry (hi, Lionbridge and TransPerfect), we’ll be focusing on the top companies that primarily provide remote interpreting services, like video and telephone interpretation. 

Let’s take a closer look.

An industry of connection

These are just a few of the companies that provide world-class interpretation services. Each has their own strengths and value propositions.

The language services industry is distinct in its sense of comradery between many of the companies that might be considered direct competitors. That’s because, at the end of the day, we’re all committed to making sure anyone can quickly communicate with limited English proficient individuals.
