Pienso

Pienso is an interactive no-code AI and machine learning platform, founded in 2016 out of MIT by Karthik Dinakar and Birago Jones and headquartered in the Washington, DC / Arlington, VA area. It lets subject-matter experts explore, train, fingerprint, annotate, and deploy deep-learning and large language models over unstructured text — customer calls, emails, documents, and social content — through a point-and-click interface with no coding required. Product capabilities include Ingest, Train & Fingerprint, Annotate, Dataset Analysis, and PromptFactory, applied to use cases such as customer insight, content moderation, document intelligence, and risk detection. Pienso is deployed into the customer's own environment — AWS, Azure, GCP, Gcore, or on-premises — so data never leaves the customer's control, and the company publishes no public developer API, SDK, or documentation surface; integration is sales-led and the platform runs as a self-contained system. Backed by Uncork Capital.

Pienso is profiled on the APIs.io network. Tagged areas include Company, Artificial Intelligence, Machine Learning, Deep Learning, and Large Language Models.

Pienso’s developer surface includes engineering blog and 8 more developer resources.
