Across the 12 most recent Series D software rounds shown, one disclosed round stands apart: Fleetio’s $450M on 2025-03-25, which dwarfs the rest of the list (the next-largest disclosed amounts are $250M for Forto on 2022-03-07 and $225M for Postman on 2021-08-18). The timeframe also clusters: 4 of the 12 rounds fall between 2025-03-25 and 2023-11-07 (Fleetio 2025-03-25, Canary Technologies 2025-06-12, May Mobility 2023-11-07, and Airspace 2022-05-25/others around it), while earlier years show a steadier cadence from 2021 onward.
Geographically, California appears repeatedly (Canary Technologies in San Francisco; Airspace in Carlsbad; Cloudbeds in San Diego; Flock Freight in Encinitas), but the list is not exclusively California-based, with notable exceptions including Forto (Berlin) and Stord (Atlanta). The segment is tightly stage-homogeneous: all 12 rows are explicitly labeled “Series D” with no “Series Unknown” or “undisclosed” amounts. The oldest disclosed round date in view is 2021-03-24 (FourKites, $100M), and the most recent is 2025-06-12 (Canary Technologies, $80M).

Frequently asked
Which Series D round is the size outlier, and how far above the rest is it?
Fleetio’s $450M (2025-03-25) is the only disclosed round above $200M in this set. The next tier tops out at $250M (Forto, 2022-03-07) and $225M (Postman, 2021-08-18), making Fleetio the clear size outlier.
Do the rounds cluster in a particular recency window rather than spreading evenly?
Yes. In the 12 rows shown, 4 rounds land between 2025-03-25 and 2023-11-07, including Fleetio ($450M, 2025-03-25), Canary Technologies ($80M, 2025-06-12), May Mobility ($105M, 2023-11-07), and Airspace ($70M, 2022-05-25) within the broader early-2020s stretch visible here. The remaining entries concentrate heavily across 2021–2022.
Are any cities repeated enough to suggest a hub pattern?
California cities recur more than other locations. San Francisco appears for Canary Technologies ($80M, 2025-06-12), Postman ($225M, 2021-08-18), Apollo ($130M, 2021-08-17), and Sourcegraph ($150M, 2021-07-13), while other California metros include Carlsbad (Airspace, $70M on 2022-05-25), San Diego (Cloudbeds, $150M on 2021-11-03), and Encinitas (Flock Freight, $215M on 2021-10-20).
What does the smallest disclosed round imply about the lower bound of this Series D set?
The smallest disclosed amount shown is $70M for Airspace (2022-05-25). With no “undisclosed” amounts in the table, the disclosed amounts appear bounded at the $70M floor through $450M at the top.
Is the stage labeling consistent, or do any entries fall under ambiguous/unknown classifications?
All 12 rows are explicitly labeled “Series D,” with no “Series Unknown” and no “undisclosed” amounts. Examples include Forto ($250M, 2022-03-07) and FourKites ($100M, 2021-03-24), both labeled Series D with disclosed amounts.
