YC idea matcher – Submit an idea and get a list of similar YC companies

This project uses semantic search, an advanced search technique that aims to understand the intent and context behind a search query instead of just matching keywords. It's built using Neon Postgres + pg_embedding and OpenAI for generating embeddings. More details can be found in the repo https://github.com/neondatabase/yc-idea-matcher

In plain words

YC Idea Matcher is a dev tool that lets users submit a business idea and receive a list of similar companies from the Y Combinator portfolio. It uses semantic search powered by OpenAI embeddings and Neon Postgres to understand the context and intent behind queries, rather than simple keyword matching. The tool helps entrepreneurs and developers explore related YC companies to their own concepts, making it useful for market research, competitive analysis, and understanding the startup landscape.
