Disclosed Series D round sizes in this AI set show a sharp upper tail: Groq’s $640M (2024-08-05) is the largest disclosed amount here, sitting well above the next-largest disclosed rounds such as Legora’s $550M (2026-03-10) and Replit’s $400M (2026-03-11) or Lightmatter’s $400M (2024-10-16). Amounts also bunch in the $60M–$300M band, while smaller disclosed rounds like Miko’s $11M (2025-11-07), temi’s $10M (2025-08-20), and Scopio Labs’ $10M (2025-07-24) sit near the low end.
The 50 rows span 2022-12-12 to 2026-03-19, with many entries concentrated in late 2024 and early 2025, including several $100M–$300M rounds (for example, Cyera $300M on 2024-11-20; Parloa $350M on 2026-01-15; Abridge $250M on 2025-02-17). Geographically, the list is heavily US-weighted by city and state repeats (notably Mountain View, CA appears multiple times: Reliable Robotics Corporation with an undisclosed amount on 2026-03-02; Qventus $85M on 2025-01-13; Groq $640M on 2024-08-05; others include multiple Bay Area entries such as Replit, Decagon, OpenEvidence, and EvenUp). Outliers in disclosure completeness also stand out: 3 entries show “undisclosed” amounts (Reliable Robotics Corporation 2026-03-02; Kasisto 2024-09-17; NeuronBasic 2023-05-23).

Frequently asked
Which disclosed Series D round is an outlier in size, and what does it imply about the rest of the list’s pricing range?
Groq’s $640M (2024-08-05) is the largest disclosed amount in these 50 rows, clearly above other high-end disclosed rounds like Legora’s $550M (2026-03-10) and the $400M rounds from Replit (2026-03-11) and Lightmatter (2024-10-16). Most other disclosed entries fall within a lower band such as $60M–$300M, with low-end disclosed rounds at $10M–$11M (temi $10M on 2025-08-20; Scopio Labs $10M on 2025-07-24; Miko $11M on 2025-11-07).
How concentrated are closures in time across this page’s 2022–2026 window?
The rows shown run from 2022-12-12 (NotCo) to 2026-03-19 (Numerion Labs), but the density is strongest in late 2024 through early 2025, where multiple $100M–$300M rounds appear in close succession (e.g., Cyera $300M on 2024-11-20; Cresta $125M on 2024-11-19; AI21 Labs $300M on 2025-05-11; Synthesia $180M on 2025-01-15). Late 2026 does show activity, but fewer entries compared with the 2024–2025 cluster.
Are any cities over-represented, and does that overlap with the largest disclosed rounds?
Yes: Mountain View, California appears repeatedly, including Groq’s $640M on 2024-08-05, Qventus $85M on 2025-01-13, and Reliable Robotics Corporation on 2026-03-02 (amount undisclosed). The Bay Area also shows multiple prominent AI rounds in this view (e.g., Replit in Foster City $400M on 2026-03-11; Decagon $250M on 2026-01-28; OpenEvidence $250M on 2026-01-21; EvenUp $135M on 2024-10-08).
What does the disclosure completeness pattern look like for “undisclosed” amounts?
Exactly three rows have an “undisclosed” amount: Reliable Robotics Corporation (2026-03-02), Kasisto (2024-09-17), and NeuronBasic (2023-05-23). That means 47 of the 50 rows provide disclosed amounts, making the size comparisons and outlier detection largely driven by disclosed figures rather than missing data.
Do the biggest rounds cluster with repeated upper-mid ticket sizes, or are they isolated?
They’re part of a broader high-ticket cluster rather than isolated: beyond Groq’s $640M (2024-08-05), several very large disclosed rounds appear across the window, including Legora $550M (2026-03-10), Parloa $350M (2026-01-15), Replit $400M (2026-03-11), Pathos $365M (2025-05-15), and Kalshi $300M (2025-10-12) or Cyera $300M (2024-11-20). Many other entries sit in the $180M–$250M range (e.g., Synthesia $180M on 2025-01-15; Decagon $250M on 2026-01-28; Abridge $250M on 2025-02-17).
Within the most recent dates on the page, how do the disclosed rounds compare to earlier extremes?
In the latest entries, disclosed amounts include Numerion Labs $20M (2026-03-19), Replit $400M (2026-03-11), Legora $550M (2026-03-10), and Oxa $103M (2026-03-04). Those late-2026 rounds reinforce the same skew seen across the page: large disclosed outliers like Legora’s $550M appear close to much smaller disclosed amounts such as Numerion Labs’ $20M, while the single biggest disclosed amount overall remains Groq’s $640M on 2024-08-05.
