How this map is made. Every startup here has raised money in a round we track that names MassChallenge as an investor, the first in 2010. 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.
Find the investors who back startups like yours, with their cheques, rounds and partners, in the app with filters, lists and exports.
