Among the 50 most recent Houston-area funded rounds shown, one disclosed amount stands out: Main Street Capital’s Education round on 2026-06-29 is listed at $1.2B, dwarfing the rest of the disclosed figures (the next-largest disclosed amounts cluster far below, e.g., NextDecade at $3.5B on 2026-06-25 and Caturus at $9.8B on 2026-05-15 are higher than $1.2B). The list is also dominated by “Energy” and “Series Unknown” disclosures: 10 entries are labeled Series Unknown, and “Energy” appears across 12 entries, with many rounds landing tightly between 2026-04-03 and 2026-06-30. That creates a temporal band where multiple Energy/adjacent deals recur in consecutive weeks (e.g., 2026-05-11 to 2026-05-06 includes Via Renewables at $325M on 2026-05-06 and Kraken Oil & Gas at $400M on 2026-05-11). Outliers are not only size-based (e.g., Caturus at $9.8B on 2026-05-15; HelloVote’s $20K on 2026-06-26) but also geography-based: one company is shown as Houston, Arkansas (Altillion on 2026-05-22), while nearly all others are Houston, Texas. Disclosed amounts run from $20K (HelloVote, 2026-06-26) up to $9.8B (Caturus, 2026-05-15), spanning 2026-03-09 through 2026-06-30.

Frequently asked
What’s the largest disclosed round in this Houston list, and how does it compare to the rest of disclosed amounts?
Caturus shows the largest disclosed amount: $9.8B on 2026-05-15. That figure is an order-of-magnitude above the lower tier of disclosed rounds, including NextDecade’s $3.5B (2026-06-25) and Solaris Energy Infrastructure’s $1.3B (2026-05-05), while several rounds sit in the hundreds of thousands to low millions (e.g., HelloVote at $20K on 2026-06-26).
Are there strong temporal clusters in the most recent entries?
Yes. The listing concentrates heavily in a narrow window from early April to end of June 2026, with multiple Energy and related deals occurring in back-to-back weeks (e.g., Via Renewables at $325M on 2026-05-06 and Solaris Energy Infrastructure at $1.3B on 2026-05-05; plus many entries on 2026-04-15 such as NanoTech Materials at $29M and eCommerce Arena at $520K). The oldest shown date is 2026-03-09 (Corastone, undisclosed).
Which stage classifications dominate, and how often are amounts undisclosed or not categorized?
Series Unknown appears 10 times among the 50 rows, and “undisclosed” amounts appear in 11 rows (e.g., Quaise Energy on 2026-06-25 and Beluga Health on 2026-06-03). In contrast, named stages are less frequent per label (for example, there are multiple Seed rounds such as Goldenrod Therapeutics at $7M on 2026-06-04 and Lium at $6M on 2026-06-10, but not near the count of Series Unknown).
Does the sector mix show any over-representation (or sector outliers)?
Energy appears across 12 entries, making it the most-represented sector in this view, with large rounds such as Caturus ($9.8B, 2026-05-15), Kraken Oil & Gas ($400M, 2026-05-11), and Solaris Energy Infrastructure ($1.3B, 2026-05-05). Biotechnology is also prominent with multiple entries (e.g., Oorja Bio at $30M on 2026-05-19 and CNS Pharmaceutical at $23M on 2026-05-04), while some sectors show single entries or small clusters.
Are there notable outliers beyond deal size, such as geographic inconsistencies?
Geography is mostly Houston, Texas, but one row is explicitly different: Altillion is listed as Houston, Arkansas with a $5M Seed on 2026-05-22. On deal size, the smallest disclosed amount is $20K (HelloVote, 2026-06-26), which sits far below typical disclosed entries like Bluejack Fire and Life Safety at $300K (2026-06-23) and Crush Security at $3M (2026-04-14).
If someone is targeting deal timing, which entries fall closest to the top of the date range shown?
The most recent date in the table is 2026-06-30, with Pie at $20M (Series A) and Kapture at $10M (Series B), both in Houston, Texas. Immediately after, 2026-06-29 includes FibroBiologics at $3M (Series Unknown) and Main Street Capital at $1.2B (Series Unknown), showing a sharp size spread even within the same two-day slice.
