Ankur A. Patel is an AI entrepreneur, thought leader, and author working at the intersection of natural language processing and business value. He is currently the cofounder and head of data at Glean, a company that uses NLP to deliver vendor spend intelligence within an accounts payable solution, helping finance teams understand and act on their spending. He is also the cofounder of Mellow, which develops easy-to-use natural language processing APIs that developers can drop into their own product builds.

Ankur is the author of two books published by O’Reilly Media: Hands-on Unsupervised Learning Using Python and Applied Natural Language Processing in the Enterprise. His writing distills hard-won lessons from production machine learning into practical guidance, covering how unsupervised techniques such as clustering, dimensionality reduction, and anomaly detection can unlock value when labels are scarce, and how enterprises can put NLP to work on real text data.

What sets Ankur apart is the loop he closes between building and teaching. As a founder, he ships NLP-driven products; as an author and speaker, he shares the patterns that work and the pitfalls to avoid. For teams exploring enterprise AI, unsupervised learning, or applied natural language processing, he offers both the practitioner’s experience and the educator’s clarity.
