Silicon Valley Startups in 2026: Names and Funding Raised
Silicon Valley startups in 2026 are mostly AI, robotics and infrastructure companies, and two leading lists name 22 and 41 of them with little overlap. Here's who is named, what they raised, and how to read the numbers.
What are Silicon Valley startups, and how many exist?
Silicon Valley startups are young, venture-backed companies based in the southern part of the San Francisco Bay Area. The boundary has shifted over the years, according to Wikipedia, and the name now sometimes covers the wider Bay Area.
No authoritative count exists. Startup Savant's 2026 list page says so, and adds that it found no reliable local failure rate for Silicon Valley startups.
It points to U.S. Bureau of Labor Statistics survival data for private-sector establishments, but says that covers businesses broadly and shouldn't be read as a rate for venture-backed startups.
The same page cites the 2026 Silicon Valley Index for $92 billion in regional venture capital investment and more than 23,000 patent registrations. This guide hasn't checked the Index itself, so treat those two figures as reported, not confirmed.
Readers often find that lists of Silicon Valley startups stretch the map. The next section shows how far.
Which Silicon Valley startups are named in 2026?
Startup Savant's list of 22 Silicon Valley startups states funding as of August 2026. The page carries no updated date, and it says the list is not ranked or exhaustive. This table shows the ten largest totals on that page.
Startup | Location | Focus | Founded | Total funding |
Figure AI | San Jose | Humanoid robots | 2022 | Nearly $2B |
Sierra | San Francisco | Customer-facing AI agents | 2023 | About $1.6B |
Together AI | San Francisco | Cloud infrastructure for AI models | 2022 | $1.3B+ |
World Labs | San Francisco | AI for creating 3D environments | 2024 | $1.2B+ |
Harvey | San Francisco | Generative AI for legal work | 2022 | $1B+ |
Physical Intelligence | San Francisco | General-purpose AI models for robots | 2024 | $1B+ |
Etched | San Jose | Chips for AI inference | 2022 | $1B+ |
Glean | Palo Alto | AI-powered enterprise search | 2019 | $765M+ |
Cellares | South San Francisco | Automated cell therapy manufacturing | 2019 | $680M+ |
Vanta | San Francisco | Security and compliance automation | 2018 | $504M |

Figure AI's September 2025 round raised more than $1 billion at a $39 billion valuation, as reported by Bloomberg. The same report shows its test facility in Sunnyvale, a different city from the San Jose address on Startup Savant's list.
Six of these ten Silicon Valley startups list San Francisco, which sits well north of the valley floor. Readers who want the city view can compare it with this guide to startups in California.
Where do the Silicon Valley startups on the list actually sit?
Counting the locations Startup Savant gives for its 22 Silicon Valley startups shows a spread across the Bay Area, with San Francisco itself the largest group.
Location on the list | Companies |
San Francisco | 9 |
Palo Alto | 3 |
San Jose | 3 |
South San Francisco | 1 |
Los Altos | 1 |
Brisbane | 1 |
Sunnyvale | 1 |
San Mateo | 1 |
Mountain View | 1 |
Redwood City | 1 |
Startup Savant's round labels aren't uniform. Sierra and World Labs carry a bare "Funding Round" label, Harvey is a "Growth Round" and Brightline a "Series C Extension", so the totals above can't be compared like for like.
Count made from Startup Savant's 2026 page. Where the valley ends is a matter of definition, so no single row is wrong.
Anyone using these Silicon Valley startups as a local sample should decide first whether San Francisco counts, since it changes nearly half the list.
Where do the two biggest Silicon Valley startups lists overlap?
Built In's list, written by Anthony Corbo and updated on 9 September 2026, names 41 Silicon Valley startups. Startup Savant names 22. At least five companies appear in both: Datasaur, Fiddler, Lyrid, Dusty Robotics and Brightline.
Built In gives no funding figures. Startup Savant does, which is why the table above leans on it.
A common pattern is that two "best of" lists for one place share few names, because each picks companies by its own method. Neither page's selection method was clear from the text reviewed.
What do funded Silicon Valley startups have in common?
Eight of the ten rows in the table describe AI or robotics work, and the oldest company in it was founded in 2018. Built In argues that venture money is concentrating in capital-intensive areas such as AI, automation and defense tech.
That fits the table, but it's one outlet's reading, not a measured finding.
Built In's examples show the spread. Xona Space Systems is building a positioning constellation of roughly 300 satellites as a GPS alternative, and Dusty Robotics makes a robot that prints building layouts on floors.
It also means Silicon Valley startups outside AI can look scarce on lists simply because they raise less. Built In also says the scene now reaches beyond small software firms into cybersecurity, fintech, healthcare, space tech and drone delivery.
Users often report that big funding totals get read as proof of a good business. A total only shows money raised. It says nothing about revenue, profit or whether the company will last.
How should you read Silicon Valley startups lists?
Treat each list as a starting point. Most Silicon Valley startups lists are written to be skimmed, so the method behind them often gets a single line or none. Three details change how much weight a list deserves:
Built In's 41 entries include investors such as Flourish Ventures, Knockout Capital, Tau Ventures, TDK Ventures and Frost Capital, which are not startups.
Startup Savant's totals are labelled with a date, but the page has no update date of its own.
Neither list shows revenue or valuation.

What should you check before quoting Silicon Valley startups funding?
Confirm the figure on the company's own announcement or a news report.
Note the date of the round, not the date of the list.
Check whether the company has since been acquired or has raised again.
Say which list you used, since the two Silicon Valley startups lists describe different samples.
Users often report that funding totals in listicles are copied from databases that lag behind announcements by months. That's a general pattern, not something measured here.
What to do next with Silicon Valley startups
Silicon Valley startups lists work as starting points, not rankings. Pick two or three companies from the table, then confirm funding on each company's own announcement or a dated news report before you quote any figure.
