SF Startups Hit a Record 1,404 Seed Deals and Where Hiring Is Booming

San Francisco just set a startup record. As the Wall Street Journal reported, the city closed 1,404 seed deals in 2025, more than double New York City's 666 and the highest count on record for the region. That gap matters for anyone looking for work, because seed money is the fuel that lets young companies start hiring. When a single metro pulls in this many early-stage deals, it signals where new jobs are about to be created. At Metaintro, we track these funding shifts so job seekers can see where opportunity is heading before the listings catch up. Here is what the numbers mean for your next move.

How Big Is the San Francisco Seed Boom?

The headline figure is the 1,404 seed deals San Francisco closed in 2025, a record for the area. The broader Bay Area story is even more dramatic. According to Crunchbase News, the region captured 45% of all US seed funding dollars in 2025, up sharply from 33% in 2024 and just 28% in 2023. That is nearly half of every early-stage venture dollar in the country flowing into one corner of California.

The concentration is not only about dollars. Crunchbase data shows the four leading metro areas, led by the Bay Area and New York, together accounted for 57% of US seed deals in 2025. Just as striking, startups based outside those top four metros pulled in only 28% of seed funding dollars, the lowest share on record and down from an average near 40% over the prior several years. The Bay Area alone accounted for roughly one-third of all US seed rounds, up five percentage points in a single year. The rest of the country split the remainder across hubs like Austin, Seattle, Miami, Chicago, Denver, and San Diego. For decades, startup activity was spread more evenly. Today it is tilting hard toward San Francisco.

This is happening even though most funded startups are still founded elsewhere. Crunchbase notes that roughly two-thirds of US seed-stage companies in 2025 remained based outside the Bay Area. The capital is concentrating faster than the founders are, which tells you the money is chasing a specific kind of company that tends to set up shop in San Francisco. Even rival hubs are feeling the pull, with Greater Los Angeles and Greater Boston each losing one to two percentage points of share since 2024 as the Bay Area gained.

What Is Driving All This Money?

The short answer is artificial intelligence. The largest and most aggressive seed rounds of the past year have gone to AI startups, and many of them are headquartered in San Francisco. That is the single biggest reason the Bay Area's share of seed funding jumped so quickly.

The scale of AI investment is hard to overstate. A separate Crunchbase analysis found that US startups raised roughly $18 billion in seed funding in 2025, with AI companies taking just over $15 billion of the global total, up about 50% from the year before. More than 42% of all global seed dollars went to AI-focused companies in 2025, up from 30% in 2024. The single clearest sign of the new scale is that nearly 700 seed rounds of $10 million or more closed during the year, on track for an all-time high.

The pull of the United States is global too. Crunchbase reports that American startups captured close to half of all global seed investment in 2025, the largest share in years and well above the 40% the country averaged over the prior six. Because the biggest of those checks were written to San Francisco AI labs, the city now sits at the center of not just the national funding map but the international one. For a job seeker, that means the gravity of the early-stage market is unusually concentrated in one place at one moment.

The biggest checks dwarf anything seed investing used to mean. Thinking Machines Lab, the AI venture founded by former OpenAI executive Mira Murati, closed a $2 billion seed round in July 2025 at a $12 billion valuation, one of the largest first rounds in Silicon Valley history. US seed financings above $100 million totaled about $3.6 billion in 2025, a new record, with Thinking Machines and a $475 million round for energy-efficiency chip startup Unconventional AI accounting for most of it. Established AI leaders raised even more at later stages, with OpenAI, Anthropic, and xAI all closing some of the largest venture rounds of the year. That money does not sit in a bank. It pays for engineers, researchers, data specialists, and the operations staff needed to scale. When a company raises this kind of capital, hiring follows quickly.

Where Is the Hiring Actually Booming?

Follow the money and you find the jobs. The AI companies pulling in the largest rounds are also the ones posting the most openings. Reporting on the San Francisco hiring market has noted that Anthropic alone listed hundreds of open roles, with a meaningful share based in or open to San Francisco, while fast-growing names like Perplexity have been adding staff at a rapid pace.

The demand is strongest in technical roles. Machine learning engineers, research scientists, infrastructure and platform engineers, and data professionals are the most sought-after. But the hiring does not stop at engineering. Funded startups also need product managers, recruiters, finance and operations staff, sales teams, and customer support as they scale from a handful of founders to a real company. A startup that raises a large round often triples its headcount within a year, and most of those new hires are not founders or researchers but the operators who keep a growing business running.

If you want to see live openings in one place, accelerator and ecosystem hubs are a practical starting point. The Y Combinator jobs board lists roles at funded Bay Area startups that are actively hiring, and the Crunchbase company directory lets you check which firms have raised recently before you apply. The pattern is consistent. The companies raising the most are the ones hiring the most, so a candidate who tracks funding has a head start on the openings.

What Does This Mean for Your Career?

If you are an engineer, researcher, or technical specialist, the San Francisco market is where the largest concentration of well-funded employers sits right now. That can mean strong compensation, since AI and infrastructure roles in the Bay Area command some of the highest base salaries in the country. National wage data from the Bureau of Labor Statistics shows software developers already earn well above the median for all occupations, and Bay Area pay typically runs higher still. It can also mean faster career growth, because early-stage companies tend to hand more responsibility to early hires than large corporations do.

But concentration cuts both ways. When so much funding clusters in one region around one technology, your prospects can become tied to the health of that single trend. A pullback in AI funding would hit San Francisco hardest, precisely because the city is the most exposed. Diversifying your skills and keeping an eye on other growing hubs is a smart hedge. It also pays to read a young company's funding history before you sign on, since a team that just closed a large round has far more runway than one that raised a small check two years ago.

You also do not have to relocate to benefit. Many funded startups hire remotely, and the skills that AI companies prize, from data fluency to working alongside automated tools, transfer to employers everywhere. The lesson from the seed boom is less about moving to San Francisco and more about building toward the kind of work that the most aggressive investors are betting on.

Is the Seed Boom Good or Bad for Job Seekers?

It is a mixed picture, and being honest about that helps you plan. On the positive side, record funding means record hiring capacity. A company that just raised a large seed round has runway to hire and a mandate to grow, which is good news for candidates.

The complication is that seed funding itself is getting harder to win even as the totals rise. A Crunchbase analysis found that more than half of all seed dollars in 2025 went into rounds of $10 million or larger, with around 350 deals landing in the $10 million to $50 million range. Mercedes Bent, a partner at Premise, captured the shift by observing that "Seed today is basically what Series A was seven years ago." She added that access to capital now leans heavily on a founder's track record, time at well-known companies, and professional network. Fewer companies are clearing that higher bar, which means hiring is concentrating in a smaller group of very well-funded winners rather than spreading across many small teams.

For job seekers, the practical takeaway is to target companies that have actually raised recently. A fresh, sizable round is one of the clearest signals that an employer can hire and pay. It also helps to read how a company plans to spend the money, since a round earmarked for compute and research may hire differently than one aimed at sales and expansion. Tracking funding announcements is no longer just an investor habit. It is a job-search strategy.

How Do New York and the Rest of the Country Compare?

New York remains the clear number-two startup hub, but the gap with San Francisco widened in 2025. With 666 seed deals to San Francisco's 1,404, New York closed less than half as many early-stage deals. Crunchbase data puts New York at roughly 17% of seed funding dollars and about 16% of deals, a share that has held steady since 2018 even as the Bay Area surged ahead.

Other regions hold smaller but real footholds. Greater Los Angeles accounted for about 5% of seed dollars in 2025 and Greater Boston for roughly 5% of dollars and 4% of deals. Beyond the top four metros, cities like Austin, Seattle, Miami, and Denver continue to support active startup scenes, even if the dollars per deal are smaller. The federal SelectUSA program and regional economic-development offices increasingly court these companies, another sign the activity is real beyond the headlines.

For candidates outside the Bay Area, the message is encouraging in one respect. Funding may concentrate, but talent does not have to. Many of these regional hubs offer lower living costs, growing startup communities, and remote roles at companies headquartered elsewhere. The record San Francisco numbers describe where the most capital landed, not the only place where good jobs exist.
