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.
