How this map is made. Every startup here has raised money in a round we track that names RA Capital Management as an investor, the first in 2006. Each sits under its main sector, read from its rounds, and each sector shows its best-funded first; sectors with fewer than three companies are left off. Rebuilt nightly; updated 15 November 2026.
