Pinecone is a leading vector database company that enables developers to build high-performance AI applications powered by vector search. Founded in 2019 by Dr. Edo Liberty, a former Director of Research at AWS with over 70 published papers on machine learning, Pinecone provides managed infrastructure to store, index, and search through billions of high-dimensional vectors in milliseconds. This allows customers like Shopify, Gong, Zapier, and Hubspot to unlock insights from large amounts of unstructured data and build applications like semantic search, recommendation engines, and generative AI.

Pinecone has capitalized on the growth of large language models (LLMs) and generative AI. By providing infrastructure to store and retrieve relevant data for models like OpenAI's GPT, Pinecone helps mitigate the "hallucination" problem of LLMs generating incorrect information. Developers can use Pinecone to implement "in-context learning", feeding relevant data to LLMs in real-time to generate more truthful and grounded outputs.

With $138M in funding from top investors like Andreessen Horowitz, Menlo Ventures, and Wing VC, Pinecone has grown rapidly to millions in annual recurring revenue and over 1,500 customers. As an employee, you'd be joining a growing 100-person company that is already a leader in a critical new category, with a strong technical team led by Dr. Liberty. However, competition from open-source vector databases and cloud providers is a challenge Pinecone will need to address as the market evolves.
