Across these 5 Monrovia-based funded startups, the largest disclosed round is Xencor’s $201M on 2024-09-11, which dwarfs the rest of the disclosed amounts (the next-largest is SiLC Technologies at $25M on 2023-11-15). That distribution is paired with a tight temporal clustering at the top of the list: 3 rounds fall between 2026-04-28 and 2026-06-25 (AcuraStem $8M, eXoZymes $2M), while another concentration sits in 2023 with SiLC Technologies $25M (2023-11-15) and VivoAquatics $2M (2023-01-25).
Sector-wise, Biotechnology appears in 3 of the 5 entries (eXoZymes 2026-06-25 $2M; Xencor 2024-09-11 $201M; SiLC Technologies 2023-11-15 $25M), while the remaining two entries split across Artificial Intelligence (AcuraStem, 2026-04-28 $8M) and Data and Analytics (VivoAquatics, 2023-01-25 $2M). Stage classifications are also skewed: 4 of 5 rounds are labeled “Series Unknown,” with only SiLC Technologies listed as “Series A.” The date window spans 2023-01-25 to 2026-06-25, and the most recent disclosed round is eXoZymes on 2026-06-25 for $2M.

Frequently asked
What stands out about round sizes in Monrovia, and which company drives the range?
The range is heavily dominated by Xencor’s $201M round on 2024-09-11; it dwarfs the rest of the disclosed amounts, with SiLC Technologies the next-largest at $25M on 2023-11-15 and only $8M and $2M levels appearing elsewhere (AcuraStem 2026-04-28 $8M; eXoZymes 2026-06-25 $2M; VivoAquatics 2023-01-25 $2M).
Are there clusters in the round dates shown, or are they evenly spread across time?
They cluster near the most recent entries: 3 of the 5 rounds occur within roughly two months of each other in 2026-04-28 to 2026-06-25 (AcuraStem $8M; eXoZymes $2M), while two other rounds anchor the earlier portion across 2023 (VivoAquatics $2M on 2023-01-25 and SiLC Technologies $25M on 2023-11-15), plus one additional large event in 2024 (Xencor $201M on 2024-09-11).
Which sectors are over-represented in this Monrovia sample?
Biotechnology is the clear concentration, appearing in 3 of 5 entries: eXoZymes (2026-06-25, $2M), Xencor (2024-09-11, $201M), and SiLC Technologies (2023-11-15, $25M). The remaining two entries are split across Artificial Intelligence (AcuraStem, 2026-04-28, $8M) and Data and Analytics (VivoAquatics, 2023-01-25, $2M).
How does the stage labeling mix look across these 5 rows?
“Series Unknown” covers 4 of 5 entries, appearing for eXoZymes ($2M on 2026-06-25), AcuraStem ($8M on 2026-04-28), Xencor ($201M on 2024-09-11), and VivoAquatics ($2M on 2023-01-25). Only SiLC Technologies is explicitly labeled “Series A” (2023-11-15, $25M).
Are there outliers by geography, sector, or amount worth focusing on?
By amount, Xencor is the outlier: $201M on 2024-09-11 is far above the next-largest disclosed round of $25M (SiLC Technologies on 2023-11-15). By sector, the outlier is less about geography (all 5 are Monrovia, California) and more about biotech dominance: 3 biotech entries versus single entries in AI (AcuraStem) and Data and Analytics (VivoAquatics).
