San Bruno’s most recent funded entries (5 rows) show a clear size outlier: Mill raised $100M on 2023-01-17, which dwarfs the next-highest disclosed round at Gather’s $26M (2021-03-11) and is far above the $13M Seed at Electroflow Technologies (2025-10-02) and $7M Seed at Empo Health (2025-06-24). Sector and stage are also concentrated: 4 of 5 companies are labeled as “Seed” or “Series Unknown/Series A,” with Seed accounting for 3 of the 5 entries (Electroflow Technologies 2025-10-02 at $13M; Empo Health 2025-06-24 at $7M; BrightGo 2023-11-13 at $3M), while Series Unknown appears once (Mill $100M on 2023-01-17) and Series A appears once (Gather $26M on 2021-03-11).
Temporally, the list clusters in the last two years: three rounds fall between 2023-01-17 and 2023-11-13 (Mill $100M; BrightGo $3M), plus two more in 2025 (Empo Health $7M on 2025-06-24; Electroflow Technologies $13M on 2025-10-02). The oldest displayed round is Gather’s 2021-03-11 $26M; the newest is Electroflow Technologies on 2025-10-02.

Frequently asked
What’s the largest disclosed round among these San Bruno entries, and how does it stack up against the rest?
Mill’s $100M disclosed round on 2023-01-17 is an outlier in this set, sitting well above the next-largest disclosed amount: Gather’s $26M on 2021-03-11. All remaining disclosed rounds are $13M or less (Electroflow Technologies $13M on 2025-10-02; Empo Health $7M on 2025-06-24; BrightGo $3M on 2023-11-13).
Do the rounds cluster into a narrow time window, or are they evenly spread across years?
They cluster in two bursts rather than spreading evenly: three entries are in 2023 (Mill 2023-01-17 $100M; BrightGo 2023-11-13 $3M; and no other 2023 rounds are shown beyond these two), and two more appear in 2025 (Empo Health 2025-06-24 $7M; Electroflow Technologies 2025-10-02 $13M). The earliest shown date is 2021-03-11 (Gather $26M), creating a gap before the 2023 activity.
Is San Bruno’s stage mix dominated by a single stage label in this list?
Yes. Seed rounds account for 3 of 5 entries (Electroflow Technologies $13M on 2025-10-02; Empo Health $7M on 2025-06-24; BrightGo $3M on 2023-11-13). The remaining 2 entries are “Series Unknown” (Mill $100M on 2023-01-17) and “Series A” (Gather $26M on 2021-03-11).
Are there notable outliers by sector, given the disclosed amounts and the sectors listed?
Mill combines the largest disclosed amount in the page ($100M on 2023-01-17) with a Sustainability sector label, unlike the smaller Seed rounds that span Materials/Chemicals/Energy (Electroflow Technologies $13M), Health Care (Empo Health $7M), and Information Technology (BrightGo $3M).
How many entries use a “Series Unknown” classification, and does that correlate with unusual deal size?
Only one entry is labeled “Series Unknown” (Mill on 2023-01-17 for $100M). In the shown set, the $100M figure is the largest disclosed amount, making the Series Unknown label coincide with the largest round here.
