Across the 50 Houston, Texas energy entries shown (round dates spanning 2020-06-23 through 2025-08-13), Quorum Software’s $865M disclosed round on 2024-11-19 is the clear size outlier: it sits well above the next-largest disclosed amounts such as Sunnova’s $425M (2022-08-15) and Intuitive Machines’ $300M (2025-08-13) and Terra Energy Partners’ $300M (2025-06-03). The dataset is also dominated by classification gaps: 33 of 50 rows are “Series Unknown” and 7 of 50 are “undisclosed,” which makes disclosed-size comparisons cluster more around the remaining disclosed rounds (e.g., Standard Carbon’s $6M on 2025-05-20 and Spearpoint Resources’ $100K on 2023-08-10). Temporally, multiple large-ticket rounds concentrate in 2024 and early 2025, with the most recent entry being Intuitive Machines on 2025-08-13 at $300M.

Frequently asked

What’s the largest disclosed Houston energy round in this list, and how does it compare to the rest of the disclosed amounts?

Quorum Software’s $865M (2024-11-19) is the standout outlier. The next-largest disclosed amounts shown are far lower, including Sunnova’s $425M (2022-08-15) and multiple $300M rounds like Intuitive Machines (2025-08-13), Terra Energy Partners (2025-06-03), and Cloverleaf Infrastructure (2024-07-17).

Which round sizes are the extremes, and what do those extremes look like relative to typical disclosed rounds here?

The smallest disclosed amount shown is Spearpoint Resources’ $100K on 2023-08-10 (Seed). At the high end, Quorum Software’s $865M on 2024-11-19 dwarfs the rest, while many disclosed rounds sit in the tens-of-millions range (for example, $40M–$53M entries like Velocys at $40M on 2024-02-06 and Utility Global at $53M on 2024-09-25).

How concentrated are the rounds by stage label, given the amount of “Series Unknown” and “undisclosed” entries?

Stage-level clarity is limited: 33 of 50 entries are labeled “Series Unknown,” and 7 of 50 show “undisclosed.” Among named stages, Seed and Series A appear repeatedly (e.g., Collide at $5M on 2025-04-15 as Seed; Aeromine Technologies at $9M on 2024-05-05 as Series A), but the majority of rows don’t provide a specific stage alongside disclosed pricing.

Are there recent time windows where larger disclosed rounds appear more frequently?

Large disclosed rounds cluster in the 2024–early 2025 window rather than evenly across the full 2020–2025 span. Examples include Quorum Software’s $865M (2024-11-19), Utility Global’s $53M (2024-09-25), and multiple large rounds in 2025 such as Intuitive Machines at $300M (2025-08-13), Renewa at $200M (2025-07-15), and W&T Offshore at $350M (2025-01-14).

What are the most recent and oldest dated entries in this Houston list, and what does that say about the lifecycle coverage?

The most recent entry is Intuitive Machines on 2025-08-13 with $300M, while the oldest dated entry shown is RPD Energy on 2020-11-04 with $300K. That spread covers roughly five years of rounds, with the biggest disclosed amount occurring late in the range (2024-11-19).
