Our Story

Vocabulary.com has its roots in the Visual Thesaurus, the interactive thesaurus and dictionary developed by the team at Thinkmap, a software company known for using visualization to facilitate communication, learning, and discovery. As the Visual Thesaurus evolved, we recognized the need for an instructional technology that would empower learners to unpack the complexity and nuances of the English language in a way that was systematic, engaging and adaptive. Our multidisciplinary team of educators, lexicographers, data scientists, and developers, united by a love of words and a good challenge, designed and built Vocabulary.com.

Our Team

The best ideas come from a variety of sources, and the best solutions are arrived at by looking at problems from multiple angles. That philosophy has shaped our team - a cohesive group with varied backgrounds and skills, united by a passion for language, learning, and understanding.
