Six funded entries tied to Northborough appear in the most recent slice of this dataset, spanning 2022-02-17 (Aspen Aerogels, $100M) through 2026-04-16 (Heart Brothers Foundation, $100K). The size distribution is bifurcated: SolmeteX’s $200M private equity round on 2025-10-16 is the only disclosed amount above $100M, while Aspen Aerogels’ $100M (2022-02-17) is the next-largest disclosed figure after a cluster of much smaller rounds ($12M on 2024-10-22; $1M on 2024-06-13; $50K on 2023-04-25; $100K on 2026-04-16).

Sector mix leans toward life/health-adjacent themes—Healthcare/Environment for SolmeteX and Biotechnology for Kyra Medical, alongside Consumer Electronics (Ozlo Sleep), Education (Heart Brothers Foundation), Community and Lifestyle (CMRK), and Energy (Aspen Aerogels)—and five of six rounds are labeled “Series Unknown.”
