Across the 27 most recent Series D consumer electronics rounds shown (dated 2021-01-07 through 2025-10-28), disclosed deal sizes cluster mostly in the tens to low hundreds of millions, but two disclosed outliers stand out: PsiQuantum raised $450M on 2021-07-27 and the next-largest disclosed is Hinge Health’s $300M on 2021-01-07. In the most recent window, the pattern shifts higher on valuation scale: four disclosed rounds from 2024-12-11 to 2025-03-24 are all $51M+ (Ayar Labs $155M on 2024-12-11; proteanTecs $51M on 2025-09-14; Eight Sleep $100M on 2025-08-19; Empower Semiconductor $140M on 2025-09-24), while two recent entries are not value-disclosed (WorkSpan on 2025-03-24 is undisclosed).
Geographically, the list is heavily concentrated in the United States (e.g., Santa Clara appears multiple times: xMEMS on 2025-10-28, Forward Networks on 2023-01-24, and PerimeterX on 2021-02-23), with additional notable clusters in the same country at different cities (New York hosts Eight Sleep 2025-08-19 and ButterflyMX 2021-12-07). Temporally, the newest rounds cluster from late 2024 through mid-2025, whereas the lower edge of the displayed set begins with Hinge Health’s 2021-01-07 and continues through 2021-11-17 (e.g., Ultraleap $81M).

Frequently asked
What’s the largest disclosed Series D round in this consumer electronics list, and how much does it dwarf the rest?
PsiQuantum’s $450M round (2021-07-27) is the top disclosed amount in the 27-row view. The next-largest disclosed amount is Hinge Health’s $300M (2021-01-07), and the remaining disclosed rounds largely sit below that two-hundred-and-fifties range.
Which recent entries are close in time, and which ones are clearly later/older edges of the dataset?
The newest disclosed round is xMEMS on 2025-10-28 at $21M, with Empower Semiconductor’s $140M (2025-09-24) and proteanTecs’ $51M (2025-09-14) immediately preceding it. The oldest disclosed (and overall earliest row) is Hinge Health on 2021-01-07 at $300M, with the dataset extending through 2021-11-17 via Ultraleap at $81M.
Are there city clusters or repeated geographies within the United States (for example, multiple Bay Area addresses)?
Santa Clara shows up repeatedly: xMEMS (2025-10-28, $21M), Forward Networks (2023-01-24, $50M), and PerimeterX (2021-02-23, $57M) all list Santa Clara. New York also clusters two companies across the period: Eight Sleep (2025-08-19, $100M) and ButterflyMX (2021-12-07, $50M).
Do undisclosed deal values affect comparisons in the newest quarters?
Only one of the 27 rows is explicitly marked undisclosed: WorkSpan (Series D, 2025-03-24). In the newest timeframe (late 2024 through 2025-03-24), the other disclosed rounds include Ayar Labs at $155M (2024-12-11), Eight Sleep at $100M (2025-08-19), and Empower Semiconductor at $140M (2025-09-24), making WorkSpan’s lack of disclosed size a key gap.
Which companies set the high-end bar in 2021, compared to 2024–2025 disclosed rounds?
In 2021, the upper tail is driven by PsiQuantum ($450M on 2021-07-27), Hinge Health ($300M on 2021-01-07), and Volocopter ($241M on 2021-03-03). In 2024–2025, the largest disclosed values are lower than those 2021 peaks, led by Ayar Labs ($155M on 2024-12-11) and Empower Semiconductor ($140M on 2025-09-24).
