To Language Services Companies


In today’s globalized world, effective communication across different languages is a vital part of both personal and business development. Businesses and individuals seeking to communicate effectively in various languages often turn to professional translation companies for assistance. In this blog post, we’ll review six of the best translation companies available, and what sets them apart. Whether you are an individual or a business, choosing the right translation service is key to breaking language barriers.

Interpreters and Translators, Inc.

Interpreters and Translators, Inc. Logo

Connecticut-based Interpreters and Translators, Inc. was founded in 1986 and has expanded to a full-service organization that boasts Fortune 100 companies and large healthcare networks among its clients. Best known for its client-centric approach, iTi offers customized solutions and personalized service.  iTi  uses human translators who are native speakers of the target language, works in over 250 languages and has over 10,000 contracted linguists. The company also offers language proficiency testing and training.

In 2023, the company launched “iTi Live,” a proprietary scheduling and reporting platform that allows its clients and linguists to manage assignments and access reporting online, along with other features.

iTi is an NMSDC-certified minority-owned business and has both ISO and ASTM certifications. Additionally, iTi has a GSA contract authorizing work for U.S. government agencies and federally funded projects, as well as contracts with several U.S. states.

  • Pros: A reputation for going above and beyond for customers. Wide variety of services. No A.I. translation. Exceptionally high customer satisfaction scores.
  • Cons: Not the least expensive company, although pricing is commensurate with the quality of services.


Transperfect logoTransPerfect, founded in 1992, has become one of the world’s largest translation companies with offices in over 90 cities worldwide. The company works in over 170 languages with more than 10,000 native-speaking linguists. TransPerfect was among the first language service companies to embrace A.I. translation tools to streamline their document translation services.

The company has a proprietary A.I. translation tool called GlobalLink, which simplifies and automates multilingual content management and localization.

TransPerfect has ISO certification and better than average customer satisfaction scores. The company works with several federal agencies and has contracts with several U.S. states.

  • Pros: Many office locations in the U.S. and abroad. Wide variety of services. Notable experience with translation and localization for websites, video games, apps, etc.
  • Cons: The size of the company means service may be less personalized. Some gaps with less common languages and dialects. High prices. Significant reliance on A.I. translation tools, although this may not be a con if used responsibly in tandem with human translators.  Some customers have reported that delivered documents required additional edits.

There is an ongoing debate about whether the use of A.I. for translation is a good thing or a bad thing. At iTi, we maintain that, although A.I. has made significant progress and can be a helpful tool for translators, it is not a viable replacement.
