Across the 50 most recent Houston rounds shown, the largest disclosed amount is Intuitive Machines on 2025-08-13 with $300M, which dwarfs the next-largest disclosed rounds (e.g., Main Street Capital at $350M on the same date is actually larger; the true runner-up set is still far below $300M once the top few are compared). At the lower edge, the smallest disclosed amount is Ainnova Tech’s $100K on 2025-08-08, standing out against many $1M–$8M seed rounds (for example, Unlimitr at $1M on 2025-11-21 and Curated For You at $8M on 2025-09-15).
Timing concentrates into a mid-2025 cluster: multiple large rounds land in August 2025 (e.g., Intuitive Machines $300M, Main Street Capital $350M, Signet Maritime $132M on 2025-08-13, plus Direct Digital Holdings $25M on 2025-08-11). Stage and disclosure are also mixed: “Series Unknown” appears frequently (e.g., several energy/software/IT entries), while “undisclosed” is present across multiple dates and sectors (e.g., Lightning Step Technologies on 2025-10-30 and SAVE on 2025-10-07). The rows span 2025-01-14 through 2025-11-21, with the most recent round at Unlimitr on 2025-11-21.

Frequently asked
What’s the biggest disclosed round in the Houston list, and how extreme is it versus the rest of the disclosed amounts?
The largest disclosed amount is Main Street Capital on 2025-08-13 with $350M. That level is far above other disclosed entries shown, including Intuitive Machines at $300M (also 2025-08-13) and several others clustered in the single-digit millions like Unlimitr ($1M on 2025-11-21) and Frame Data & AI ($4M on 2025-11-06).
Are there visible time clusters, or are rounds spread evenly across the date range?
The list is not evenly distributed: August 2025 shows a dense pocket of large and mid-sized deals, including $350M (Main Street Capital) and $300M (Intuitive Machines) on 2025-08-13, plus $132M (Signet Maritime Corporation) on 2025-08-12 and $25M (Direct Digital Holdings) on 2025-08-11. Earlier months still appear (e.g., VAALCO Energy at $190M on 2025-03-05), but the magnitude and concentration in August are notable.
Does disclosure happen consistently, or are there many “undisclosed”/“Series Unknown” classifications that affect comparisons?
Disclosure is uneven: multiple rounds show “undisclosed” amounts such as Lightning Step Technologies (2025-10-30) and SAVE (2025-10-07). Separately, “Venture - Series Unknown,” “Series Unknown,” and “Private Equity” recur across different sectors (e.g., Koda Health on 2025-09-15 as Venture - Series Unknown with $12M; Intuitive Machines on 2025-08-13 as Series Unknown with $300M), which makes cross-company comparisons dependent on which rounds have disclosed amounts.
Where does the stage mix land, and how does it vary between small and large checks?
Many of the smallest disclosed checks appear in seed-era rounds, such as Ainnova Tech’s $100K on 2025-08-08 (Series A) contrasted with seed rounds like Unlimitr at $1M (2025-11-21) and Curated For You at $8M (2025-09-15). The largest disclosed rounds come from Series/round types labeled broadly (“Series Unknown” for Intuitive Machines at $300M on 2025-08-13; “Series Unknown” for Signet Maritime at $132M on 2025-08-12), indicating that the highest-dollar entries are not tied to a single named stage label.
Are there outliers in sector patterns worth flagging beyond energy and healthcare?
Yes: two standout capital-intense entries sit outside the most repeated small-dollar seed pattern. Intuitive Machines ($300M on 2025-08-13, Energy) and Main Street Capital ($350M on 2025-08-13, Education) both materially exceed many other disclosed deals, including healthcare/biotech rounds like Cellvie ($5M on 2025-09-09) and CNS Pharmaceutical ($5M on 2025-05-13). In addition, hardware shows meaningfully sized checks such as Logix Fibre Networks ($45M on 2025-04-14) and Lyte Fiber ($58M on 2025-04-23), which can skew sector-level comparisons when treating all industries as similar in funding scale.
