Among the 21 Austin-based energy companies listed, Base Power’s $1.0B Series C on 2025-10-07 is the only disclosed round that dwarfs the rest: the next-largest disclosed amount is Jupiter Power at $286M (2025-03-18), while most other disclosed rounds cluster far below that level (for example, $40M on 2024-12-17 and $22M on 2023-11-02). The list also shows repeated “undisclosed”/“Series Unknown” classifications: 2 rounds show “undisclosed” amounts (CleanArc Data Centers on 2025-04-16 and Gage Zero / Bodhi / ClearTrace on 2023-05-02, 2023-02-16, and 2023-02-16), and 9 additional rounds label the round as “Series Unknown” with a disclosed amount (e.g., Hexium $3M on 2025-04-15; CleanPlanet Chemical $30M on 2025-03-12).
Temporally, funding is concentrated in a recent window: 2025 accounts for five of the 21 rows, spanning 2025-04-15 (Hexium $3M) through 2025-10-07 (Base Power $1.0B). Earlier entries extend back to 2020-07-15 (Green Revolution Cooling $7M), and the sector label is consistently “Energy” across all rows (no alternate sub-sector shown in the data).

Frequently asked
What stands out as the largest disclosed round in Austin energy here, and how extreme is it versus the next-largest disclosed amount?
Base Power’s $1.0B disclosed Series C on 2025-10-07 is an outlier: the next-largest disclosed amount is Jupiter Power’s $286M on 2025-03-18, with most other disclosed rounds—such as CleanPlanet Chemical’s $30M on 2025-03-12 and Talus Renewables’ $22M on 2023-11-02—well below $100M.
Are there concentrated funding windows among these most recent 21 rows?
Yes. Five of the 21 rows are dated in 2025, spanning 2025-04-15 (Hexium $3M) through 2025-10-07 (Base Power $1.0B). The next densest cluster is mid-2023, where multiple entries occur in quick succession (e.g., Pecan Street $3M on 2023-06-14 and Yotta Energy $8M on 2023-09-19, with three “undisclosed” rows around Feb 2023: Bodhi, ClearTrace, both dated 2023-02-16).
How complete are round and amount disclosures in this list (undisclosed vs “Series Unknown”)?
Round type is often not specified: 9 rows are marked “Series Unknown” with disclosed amounts (e.g., CleanPlanet Chemical $30M on 2025-03-12; Infinity Water Solutions $650K on 2024-07-05; Yotta Energy $8M on 2023-09-19). Separately, 2 rows use “undisclosed” for the amount (CleanArc Data Centers on 2025-04-16, and Gage Zero on 2023-05-02).
Which stages appear repeatedly, and does that imply a mix toward early or later rounds?
Later-stage labels show up, but earlier rounds are more visible in the named entries. Examples of later-stage classification include Base Power (Series C on 2025-10-07) and Branch Energy (Series A on 2024-08-07 and other Series A examples like Talus Renewables $22M on 2023-11-02), while early-stage labels include 360 Mining, Inc. (Seed $2M on 2022-12-08) and SeekOps (Series B $14M on 2021-07-01). Several other rows avoid stage specificity via “Series Unknown” (e.g., Hexium $3M on 2025-04-15).
Are there meaningful low- and high-end disclosed amount gaps worth flagging for research or outreach prioritization?
The smallest disclosed amount is Frontier Bioenergy Systems’ $100K on 2022-03-09, which is far below the broad middle of disclosed rounds (e.g., Semtive $6M on 2021-04-02 and Infinity Water Solutions $650K on 2024-07-05). At the top end, Base Power’s $1.0B on 2025-10-07 creates a steep separation from other large disclosed rounds like Jupiter Power’s $286M on 2025-03-18.
