Among the 34 listed Lexington-area entries, the largest disclosed round is Alzheon’s $100M Series E on 2024-06-12, which sits far above the rest of the disclosed amounts: the next-largest disclosed figures are $66M (Concert Pharmaceuticals, 2022-06-01) and $63M (Accent Therapeutics, 2020-04-23), while most other disclosed rounds fall in the low double-digits (e.g., Fractyl Health $23M on 2025-08-05; Hemanext $19M on 2025-07-22). Geographically, “Lexington, Massachusetts” and “Lexington, Kentucky” dominate, with “Lexington, South Carolina” appearing only once (RiskAdvisor, Seed, 2025-04-01, undisclosed). Timing is also clustered: 2025 accounts for 6 of the 34 rounds, led by entries on 2025-08-19 (Cognition Corporation, $2M) and 2025-08-05 (Fractyl Health, $23M). Stage reporting is mixed—14 of 34 rows use “Series Unknown” and 2 of 34 are “undisclosed” amounts—so investor comparisons often hinge on disclosed rounds only. The span runs from 2020-04-23 (Accent Therapeutics, $63M) through 2025-08-19 (Cognition Corporation, $2M).

Frequently asked
What outlier financing sizes stand out, and how do they affect comparisons across the Lexington list?
Alzheon’s disclosed $100M Series E on 2024-06-12 is the only round above $50M, dwarfing the next-largest disclosed amounts of $66M (Concert Pharmaceuticals, 2022-06-01) and $63M (Accent Therapeutics, 2020-04-23). Below that, disclosed rounds cluster heavily in single to high double digits (e.g., VulnCheck $12M on 2025-03-18; Hemanext $19M on 2025-07-22), so scale-based comparisons are very sensitive to that one Alzheon datapoint.
Do the entries cluster by city or geography within “Lexington”?
Most rounds are concentrated in Lexington, Massachusetts (e.g., Fractyl Health $23M on 2025-08-05; Alzheon $100M on 2024-06-12; Cognition Corporation $2M on 2025-08-19) and Lexington, Kentucky (e.g., Payhoa $28M on 2024-04-22; Rubicon $20M on 2024-12-03; Ramaco Resources $175M on 2023-02-17). Lexington, South Carolina appears only once in the shown set: RiskAdvisor on 2025-04-01 with an undisclosed amount.
Which rounds landed most recently, and what do the last ~90 days look like by disclosed size?
The most recent date is 2025-08-19 (Cognition Corporation, $2M). Within the most recent 90 days shown, disclosed rounds include Fractyl Health $23M (2025-08-05), iSpecimen $4M (2025-07-24), and Hemanext $19M (2025-07-22), indicating a skew toward mid-to-high teens and single digits rather than the $50M+ range seen elsewhere (e.g., Alzheon $100M on 2024-06-12).
What stage mix dominates, and how much of the list is not directly comparable by stage or amount?
“Series Unknown” appears in 14 of 34 rows, and “undisclosed” amounts appear in 2 of 34 rows (RiskAdvisor on 2025-04-01; Faradine Systems on 2023-07-17). Because of that, stage-and-size comparisons often rely on the remaining disclosed rows—such as VulnCheck’s Series A $12M on 2025-03-18 and Hemanext’s Series B $19M on 2025-07-22—rather than the full 34-entry set.
Are there sector concentrations that suggest a thematic cluster?
Biotechnology is the clearest multi-entry sector in the shown rows, with multiple entries across time and companies: Fractyl Health (2025-08-05, $23M), iSpecimen (2025-07-24, $4M), Alzheon (2024-06-12, $100M), Alloy Therapeutics (2022-10-03, $42M), Carbon Biosciences (2022-06-21, $38M), and Concert Pharmaceuticals (2022-06-01, $66M). Several other sectors appear only once or twice (e.g., Consumer Electronics: Rubicon $20M on 2024-12-03; Space Tango $5M on 2024-02-21).
Which disclosed amounts sit at the low end or are otherwise extreme relative to the rest?
The smallest disclosed amount is Hope Center’s $10K grant on 2023-07-12, which is far below typical disclosed rounds in this list (for example, Community Ventures $860K on 2024-09-17 and OmniLife $1M on 2022-03-01). On the opposite side, Ramaco Resources shows an additional very large disclosed figure ($175M on 2023-02-17), creating a second high-scale outlier even though the largest disclosed amount overall remains Alzheon at $100M (2024-06-12).
