Short answer (as of July 2026): The Seattle-area companies we cover with /startup/ profiles cluster around enterprise software, AI infrastructure, generative media, off-road autonomy, offensive security, and reusable launch — not a full census of every Puget Sound startup. Core set: Apptio (Bellevue), Temporal (Bellevue HQ commonly cited), Chestnut and Irreverent Labs (Seattle), Overland AI (Seattle HQ commonly cited), Stoke Space (Kent), and XBOW (Seattle HQ commonly cited). Databricks is Bay Area — not Seattle. Samsara is San Francisco — not Seattle.

Why this list (primary JTBD)

Primary audience: founders and investors shortlisting real companies in our directory tied to Seattle / Bellevue / Kent — not a scraped “top startups” blog.

Jobs this page finishes:

1. Confirm what they do and why they matter.
2. See stage / status and HQ honesty.
3. Jump to investor fund pages when we have them.
4. Know what we are missing.

Seattle-area startups in our directory

HQ rules: prefer hq from startup JSON. If missing, we say “HQ commonly cited as…” only after public verification. Investor links use whitelist /fund/ IDs only.

Company briefs (why each is on the map)

Apptio — Bellevue enterprise proof that Seattle can define a software category (FinOps / TBM). a16z’s first portfolio investment; Greylock participated; path ran IPO → Vista → IBM acquisition. Use it as the exited enterprise reference, not an active raise target.

Temporal — The clearest 2026 AI-infra signal in the metro: orchestration, retries, and state for agentic and cloud-native workloads. Series D led by a16z with Sequoia and Tiger Global among directory-linked participants. Deal write-up: Temporal $300M Series D.

Chestnut — Quiet Seattle enterprise SaaS: insurance carrier distribution systems (producer lifecycle and incentive comp). Early a16z backing; useful if you care about vertical SaaS wedges into regulated back offices.

Irreverent Labs — Seattle generative-video bet after a crypto-gaming pivot. a16z led seed and Series A; Pear VC participated. Shows the metro can host media-AI, not only B2B infra.

Overland AI — Off-road autonomy for unmapped terrain (defense logistics, industrial). Large Seattle-area round in Q1 2026 coverage. Deal write-up: Overland AI $100M.

Stoke Space — Kent hard tech: full reusability including the second stage. Anchors Seattle’s space narrative alongside regional aerospace talent. Deal write-up: Stoke Space $350M.

XBOW — Offensive-security AI that continuously probes exploitability (not annual pentest theater). Series C in the Q1 2026 Seattle capital concentration story. Deal write-up: XBOW $120M Series C.

Do not mislabel (related, not Seattle HQ)

If a company only has customers or a satellite office in Redmond/Bellevue, that is not enough for this hub.

Microsoft / Amazon context (talent, not logos)

Seattle startups in this set usually win diligence on systems engineering and enterprise GTM, shaped by Microsoft and Amazon talent density:

• Cloud cost, identity, and workflow problems (Apptio, Temporal)
• Autonomy and security problems that need serious software + hardware integration (Overland, XBOW, Stoke)
• Vertical back-office modernization (Chestnut)

That gravity explains why enterprise and hard tech dominate our Seattle coverage versus consumer or consumer-fintech depth in NYC.
