Show HN: A 3D visualization of all YC startups based on their mission statements (www.startup-galaxy.com)

A new Show HN project presents an interactive 3D sphere that maps every Y Combinator startup by the similarity of their mission statements. Users can drag to rotate, scroll to zoom, and hover to reveal company names; points are clustered by sector and colored by macro groups so you can explore clusters at a glance and zoom in to inspect individual companies. The visualization translates textual mission statements into a spatial layout that highlights proximity between startups with related goals or language. For the AI/ML community this is a neat, practical demonstration of how modern NLP — likely sentence embeddings combined with dimensionality reduction and a spherical projection — can turn unstructured text into an exploratory, high-density view of an ecosystem. It’s useful for market mapping, competitor discovery, trend spotting, and building labeled datasets for downstream tasks. Key technical implications: layout and cluster quality depend heavily on the embedding model and the chosen reduction/projection method (e.g., PCA/UMAP/t-SNE and any spherical mapping), and mission-statement noise or phrasing bias will influence groupings. The tool is both a visualization showcase and a prompt to consider how text representation choices shape our understanding of industry structure.
