California remains one of the most active states for venture-backed company formation across the 29 recently funded startups shown here, spanning rounds from a $1M Pre-Seed to a $35M Series A. Artificial intelligence threads through the broadest cross-section of the set — Hammerhead AI (AI + Energy + Hardware, $10M Seed, November 2025), CWX (AI + Cloud + Cybersecurity, $23M venture, October 2025), and Parasail ($10M Seed, April 2025) all closed within the past year, signaling continued early-stage conviction in the sector.
Beyond AI, the data shows meaningful activity in blockchain (Perena, MinionLab, Polyhedra Network), hardware (Matter Intelligence at $12M Seed, Orca), and biotech (Vironexis Biotherapeutics at $26M Seed in September 2024, Atomic AI at $35M Series A in January 2023). Seed and Pre-Seed stages account for the majority of entries, with only three Series A rounds visible — Atomic AI, Exa ($17M, July 2024), and XFactor ($16M, April 2024). A meaningful share of rounds list undisclosed amounts, particularly among angel and early pre-seed entries.

Atomic AI leads with a $35M Series A closed in January 2023, followed by Vironexis Biotherapeutics at $26M Seed (September 2024) and CWX at $23M venture (October 2025). Exa ($17M Series A, July 2024) and XFactor ($16M Series A, April 2024) round out the top five disclosed amounts in this set.
Which sectors appear most frequently across these 29 rows?
Artificial Intelligence is the most represented sector, with at least eight companies including Hammerhead AI, Uare.ai, CWX, Parasail, Exa, MeetRecord, Monetizy, and Circle Security. Blockchain and cryptocurrency claims three entries (MinionLab, Perena, Polyhedra Network), and hardware accounts for three more (NZXT, Orca, Matter Intelligence).
What round stages dominate this California dataset?
Seed is the most common stage, appearing across roughly a third of the 29 rows. Pre-Seed accounts for four entries (Quantum Light, MinionLab, M37Labs, Perena, Homster). Three Series A rounds are present — Atomic AI, Exa, and XFactor — representing the clearest growth-stage signal in this slice.
How many companies closed rounds with undisclosed amounts?
At least eight companies in this set did not disclose round size, including Ris Rx, Monetizy, M37Labs, Luna Peak Foundation, Insights Wealth Management, Orca, Circle Security, and Homster. That represents roughly 28% of the 29 rows, so disclosed totals significantly understate actual capital deployed.
How far back does the funding activity in this set extend, and how recent is the latest entry?
The oldest entry is Code2, which closed a $1M Seed in April 2021. The most recent is Hammerhead AI, which raised a $10M Seed on November 18, 2025. The bulk of activity — roughly 20 of the 29 rows — falls between mid-2023 and late 2025.
