Across the 50 most recent “Software Development” deals labeled “Series Unknown,” the largest disclosed round is Workleap’s $93M (2023-06-06), which dwarfs the rest of the disclosed amounts; the next-highest disclosed entries sit far below it (for example, Scope3 at $25M on 2024-10-10 and Datalex at $28M on 2024-09-26). A strong temporal cluster appears in mid-to-late 2024: multiple rounds land between 2024-05-03 and 2024-11-13, including Curbside SOS ($26M, 2024-05-10), Scope3 ($25M, 2024-10-10), and Datalex ($28M, 2024-09-26).
Geographically, the list is more internationally distributed than city-centered: the most frequent explicit geography is not a single city but repeated countries/regions (for example, multiple entries in the United States plus several in the UK, Canada, and Europe). Disclosure is also skewed toward undisclosed amounts: 19 of 50 rows are “undisclosed,” with disclosed checks ranging from NatureQuant’s $100K (2024-05-07) up to Workleap’s $93M. The most recent row is AnnieCannons on 2025-08-01 (undisclosed), while the oldest shown dates to Boardable on 2022-11-09 ($3M).

Frequently asked
What’s the largest disclosed round in this “Series Unknown” software-development set, and how does it change the distribution?
Workleap’s $93M (2023-06-06) is the only disclosed amount above $50M, and it sits well beyond the next-largest disclosed rounds such as Datalex’s $28M (2024-09-26) and Scope3’s $25M (2024-10-10).
Do these rounds cluster in time, especially near mid-to-late 2024?
Yes—2024 shows a concentration of disclosed and undisclosed rounds from early May through November, including NatureQuant ($100K on 2024-05-07), Curbside SOS ($26M on 2024-05-10), Onform ($3M on 2024-06-12), and Scope3 ($25M on 2024-10-10).
How often are amounts undisclosed, and does that affect what can be compared?
Undisclosed amounts dominate: 19 of 50 rows are “undisclosed,” so comparisons rely on the remaining disclosed subset. Notable disclosed lows include NatureQuant’s $100K (2024-05-07) and HR Bot Factory’s $320K (2023-01-11), while many recent entries like AnnieCannons (2025-08-01) provide no dollar figure.
Are there clear outliers besides the largest check size?
Yes: the disclosed range includes very small rounds relative to the top end, such as $100K (NatureQuant, 2024-05-07) versus $93M (Workleap, 2023-06-06). That spread is visible even within the same series label, despite “Series Unknown” being consistent across entries.
Is there a single city concentration, or is the geography broadly dispersed?
The list is broadly dispersed across countries rather than concentrated in one repeated city; examples include multiple US locations (e.g., Curbside SOS in Eastpointe, Scope3 in New York, and Onform in Fort Collins) alongside Europe and the UK (e.g., Datalex in Dublin and Appex in Boston but Taclia in Barcelona). Canada and the UK also appear multiple times (e.g., NLPatent in Toronto, Connect2Co in Wilmington, and StrikeX in London).
