Within this Boston-focused set of 50 most-recent rounds, the largest disclosed amount is Anagram Therapeutics at $250M (2026-05-07). That $250M figure dwarfs the rest of the disclosed rounds, which mostly cluster below $100M; the next-largest disclosed amounts are Blitzy’s $200M (2026-05-05) and Beeline Medicines’ $126M (2026-06-30), while many rounds sit in smaller single- and tens-of-millions ranges.
The list also concentrates heavily in a tight late-spring window: multiple rounds land in mid-to-late May 2026 (for example, Tomorrow.io’s $35M on 2026-05-18, Catena Labs’ $30M on 2026-05-20, and Cerevance’s $20M on 2026-05-12), with the newest dated rounds appearing on 2026-06-30 (Beeline Medicines $126M and Pyxis Oncology $50M) and the oldest dated round shown on 2026-04-13 (Elevate Renewable Energy, $50M). Sector-wise, Healthcare, Biotechnology, and AI recur across the entries, and 23 of 50 rows are “Series Unknown” or “undisclosed,” creating a stage-mix blind spot alongside the AI/Bio-heavy concentration.

Frequently asked
Which disclosed round is the clearest outlier in Boston here, and how much bigger is it than the rest of the disclosed amounts?
Anagram Therapeutics’ $250M disclosed round on 2026-05-07 is the largest in the table; it is materially above the next-largest disclosed amounts, including Blitzy’s $200M (2026-05-05) and Beeline Medicines’ $126M (2026-06-30).
Is there a temporal cluster among these Boston rounds, or are dates evenly distributed?
Dates are concentrated in a narrow window from 2026-04-13 to 2026-06-30, with a visible mid-May cluster (e.g., Blitzy $200M on 2026-05-05, Cerevance $20M on 2026-05-12, Tomorrow.io $35M on 2026-05-18, and Catena Labs $30M on 2026-05-20).
How much of this list lacks disclosed round size or series classification?
23 of 50 rows are either “Series Unknown” or “undisclosed” (including examples like East Range Group on 2026-06-24 with “undisclosed” and Anodyne Nanotech’s counterpart rounds with series labeled unknown in other entries). This reduces confidence when comparing stage and deal-size patterns across the dataset.
Do any industries appear repeatedly enough to form a pattern, rather than one-off categories?
Yes: Biotechnology appears in multiple entries such as Beeline Medicines (Series A, $126M on 2026-06-30), Anodyne Nanotech (Series A, $13M on 2026-06-24), and Cerevance (Series C, $20M on 2026-05-12). AI also recurs (e.g., Nebulock $25M on 2026-06-25, SOPHiA GENETICS $58M on 2026-06-16, and Foundation $6M on 2026-05-21).
Which entries have the smallest disclosed amounts, and are they consistent with the rest or unusually low?
The smallest disclosed amount shown is $250K: Microvitality on 2026-06-16 ($250K) and Carmyn on 2026-06-01 ($300K) sit at the low end compared with larger disclosed rounds like Pyxis Oncology’s $50M (2026-06-30) and Elevate Renewable Energy’s $50M (2026-04-13).
What does the stage labeling suggest about comparability across the list?
Stage labels are mixed, with many rounds carrying “Series Unknown” and several having “undisclosed” amounts, including Pyxis Oncology (Series Unknown, $50M on 2026-06-30) and Merlin Labs (Series Unknown, $80M on 2026-04-29). Where series is specified, there are still large variations in disclosed size—for instance, Blitzy is labeled Series A at $200M (2026-05-05) while other Seed rounds like BoolSi are far smaller at $6M (2026-06-18).
