About the data (Fundz)
Figures in this article come from Fundz funding records and company profiles. We used round date, round location, money raised, currency, sector tags, and any disclosed investor lists. Where locations were incomplete, we backfilled from company profiles. Non-USD amounts were converted to USD for consistency. Investor roles reflect what was disclosed; when lead versus participant was not identified, parties were grouped. Late-reported rounds may appear in future updates.
What stood out
Washington’s tape mixes one very large raise with several strong mid-sized rounds. Expect two purchase tempos over the next 2–8 weeks: quick pilots where value is clear, and careful enterprise evaluations where security and ROI matter.
- Totals: 20 deals | $1.05B total | $10.2M median | $52.4M average
- Read: Significant activity in software, AI, IT, and advanced manufacturing, with aerospace commanding the single largest check
Where the money went (by industry)
Dollar share clustered in a handful of categories:
- Aerospace Manufacturing — $510.0M (1 deal)
- Software — $289.7M (2 deals)
- Information Technology — $51.0M (2 deals)
- Artificial Intelligence, Software — $50.0M (1 deal)
- Manufacturing — $43.6M (3 deals)
- Biotechnology Manufacturing — $42.9M (4 deals)
- Artificial Intelligence, Health Care — $28.0M (1 deal)
- Biotechnology, Health Care — $10.6M (1 deal)
- Health Care — $10.0M (3 deals)
- Events — $6.9M (1 deal)
What this suggests: the state’s strengths in aerospace, developer and infrastructure software, AI, and industrial or biotech were all active. Expect near-term demand for security, data, infrastructure, and manufacturing or operations software, as well as selective health and biotech tooling.
The biggest disclosed rounds
These raises shaped the month (USD values):
- Stoke Space — $510.0M on 2025-10-08 (Aerospace, Manufacturing)
- Chainguard — $280.0M on 2025-10-23 (Software)
- Phaidra — $50.0M on 2025-10-01 (Artificial Intelligence, Software)
- CoreStack — $50.0M on 2025-10-20 (Information Technology)
- Brook.Ai — $28.0M on 2025-10-16 (Artificial Intelligence, Health Care)
- Carbon Robotics — $20.8M on 2025-10-22 (Manufacturing)
- Membrion — $20.0M on 2025-10-20 (Biotechnology, Manufacturing)
- Circulate Health — $10.6M on 2025-10-22 (Biotechnology, Health Care)
- Airship AI — $9.7M on 2025-10-17 (Software)
- Banzai — $6.9M on 2025-10-22 (Events)
Why these matter: expect follow-on hiring and product changes as these companies deploy capital, especially in platform, data, security, and go-to-market operations. Watch for new enterprise plans, trust and security pages, and senior openings.
What the stage picture means (plain English)
Many rounds in this dataset do not include a clear stage label, but the check sizes provide a good guide:
- $1–10M: Fast pilots, light integrations, short sales cycles
- $10–50M: Expansion projects with clear metrics and more stakeholders
- $50M+: Platform bets with detailed security, ROI models, and reference checks
If your buyer is in regulated or industrial segments (health, biotech, aerospace or defense), bring security and compliance material early. For software, AI, and IT, lead with time-to-value and integration depth; widen the committee after initial outcomes land.
A fair ex-outlier view
Stoke Space’s $510.0M is a clear outlier. Ex-Stoke Space, Washington totals approximately $540.0M across 19 deals, with the average dropping to about $28M and the median staying near $10.2M. The mid-market is active even without the largest aerospace raise.
Investor view (as disclosed)
Several rounds in this window list participants without clearly labeled leads. Where disclosed, participants trend toward security, infrastructure, and industrial-aligned investors. We’ll surface a fuller “most active” view as more lead/participant details are reported.
How to use this information (next 2–12 weeks)
Start with the companies above, then work down the list by sector and round size. A simple plan keeps teams moving and reduces stalls.
- Weeks 0–2: confirm problem fit and show the product live, tailored to sector needs
- Weeks 3–6: scope a pilot with clear success criteria and data requirements; map decision makers and approvers
- Weeks 7–12: share ROI estimates, security details, and references; finalize scope, pricing, and timeline
Signals to watch, often within 2–6 weeks after a raise:
- New pricing tiers or enterprise plans
- Hiring for Head or Director roles in Data, Security, Platform or Infrastructure, and RevOps
- Partner announcements with cloud providers, channels, or systems integrators
Method (short)
- Dates: Oct 1–31, 2025
- Size range: $1M–$1B
- Location: Washington State is listed as the round location (fallback to the company city only if the round city was missing)
- Currency: USD; simple FX used to convert non-USD amounts for comparison
- Industries: As labeled in the dataset; combined tags kept where present
- Investors: As disclosed; where lead versus participant was not specified, parties are grouped
- Multiple closes: Some companies reported multiple closes in the period; we list entries as disclosed. Where multiple entries belong to a single round, totals may be consolidated in later updates.
The Bottom Line
Washington’s October results show both scale and depth. One aerospace mega-round grabbed headlines, but the broader story is strong activity in software, AI, IT, and advanced manufacturing, with many rounds in the $10–50M band that turn into real projects. If you match your proof to the buyer’s needs and time outreach to the post-funding signals, you will be in the right conversations as budgets open.
