Frequently asked
What’s the largest disclosed round in Northborough in this list, and how different is it from the rest?
SolmeteX’s $200M private equity round (2025-10-16) is the largest disclosed amount and stands well above the next-largest disclosed deal: Aspen Aerogels’ $100M (2022-02-17). The remaining disclosed rounds are $12M (Ozlo Sleep, 2024-10-22), $1M (Kyra Medical, 2024-06-13), and $50K (CMRK, 2023-04-25).
Do the recent rounds cluster in time, or are they evenly spread across the period shown?
They cluster toward the later end of the window: three of the five rounds fall between 2024-06-13 (Kyra Medical, $1M) and 2025-10-16 (SolmeteX, $200M). The earliest entry shown is 2022-02-17 (Aspen Aerogels, $100M), with the other two dates landing in 2023-04-25 (CMRK, $50K) and 2024-10-22 (Ozlo Sleep, $12M).
Which stage labels dominate, and what fraction of deals are not clearly categorized?
“Series Unknown” dominates, covering four of five entries: Ozlo Sleep ($12M, 2024-10-22), Kyra Medical ($1M, 2024-06-13), CMRK ($50K, 2023-04-25), and (implicitly) the remaining row besides SolmeteX and Aspen Aerogels. The two explicitly labeled stages are SolmeteX as “Private Equity” ($200M on 2025-10-16) and Aspen Aerogels as “Post-IPO Debt” ($100M on 2022-02-17).
Are any sectors over-represented across these Northborough entries?
Sector coverage is limited in count rather than breadth: the list includes Energy (Aspen Aerogels, $100M on 2022-02-17) and multiple Healthcare-adjacent themes (SolmeteX as Healthcare/Environment, $200M on 2025-10-16; Kyra Medical as Biotechnology, $1M on 2024-06-13). Consumer Electronics (Ozlo Sleep, $12M on 2024-10-22) and Community/Lifestyle (CMRK, $50K on 2023-04-25) appear once each.
Are there outliers in deal size or sector that would merit separate underwriting attention?
Yes on size: CMRK’s $50K community/lifestyle round (2023-04-25) is the smallest disclosed amount and sits far below the rest of the disclosed rounds ($1M to $200M). On the high end, SolmeteX’s $200M (2025-10-16) is a clear outlier versus the rest, and it is also the only entry marked “Private Equity,” contrasting with Aspen Aerogels’ “Post-IPO Debt” labeling for $100M (2022-02-17).
