About Massachusetts

Massachusetts's Form D filings are dominated by the Boston metro — Boston, Cambridge, Watertown, Waltham, Lexington — which hosts one of the world's densest biotech clusters alongside major AI/ML, SaaS, fintech, and robotics activity. Cambridge's Kendall Square is the global epicenter for biotech venture capital. Boston-metro filings span every sector at scale: biotech Series A–C rounds of $30M–$200M+, AI/ML foundation-model-adjacent rounds, SaaS growth rounds, and robotics/automation Series B/C. Western Massachusetts (Amherst, Springfield) contributes smaller filings. Delaware incorporation is universal for operating companies; Massachusetts LLCs appear for real-estate vehicles.

In 2026, Massachusetts accounts for 255 catalogued filings totaling $6035.6M, running at roughly 56.3 filings per week over the last 30 days.

About private capital in Massachusetts

Massachusetts has high state taxes but extraordinary capital-markets, university-research, and life-sciences infrastructure that sustain high filing volume. Kendall Square's biotech density — MIT, Harvard Medical, Broad Institute, Whitehead Institute, and dozens of pharma corporate labs — produces filings visible nowhere else in the country. Boston's SaaS and growth-equity ecosystem drives mid-to-large-stage tech filings. The state's robotics and automation cluster (iRobot-ecosystem alumni, MIT CSAIL spinouts) produces distinctive hardware filings. Worcester's emerging biotech and medtech sub-hub adds volume. Real-estate vehicles target Boston-metro multifamily and lab-space assets.

Massachusetts funding trends

Recent Massachusetts Form D filings show several dominant patterns. First, biotech filings account for an outsized share of the state's dollar volume — large rounds, long time horizons, specialized life-science investor bases. Second, AI/ML companies from the Boston-MIT ecosystem file regularly at mid-to-large stages. Third, SaaS and developer-tools companies file Series A–C rounds. Fourth, robotics, autonomous-systems, and advanced-manufacturing companies produce distinctive filings. Fifth, lab-space and life-sciences-real-estate vehicles appear regularly. Massachusetts reliably ranks in the top filing states by both volume and dollar total.
