Best NLP Software Development Firms in the US

Think about the last time you interacted with a smart assistant, a customer support chatbot, or a recommendation engine that seemed to “get you.” 

Behind every seamless interaction is Natural Language Processing (NLP), the technology that lets machines understand and respond to human language. 

And the numbers show why it matters: the global NLP market is projected to grow from $30 billion in 2024 to nearly $800 billion by 2034. What was once a niche experiment is now central to business operations, customer experience, and automation. Companies that don’t adopt NLP risk falling behind, missing opportunities to engage users and optimize workflows.
