This is a weekly feature that runs down the week鈥檚 Top 10 announced funding rounds in the U.S. Check out last week鈥檚 biggest funding deal roundup here.

After a week of multiple billion-dollar-plus rounds, startup investors have reduced the number of zeroes on their funding checks. This past week, the largest U.S. startup funding rounds were in the hundreds of millions, topped by a $550 million financing for AI infrastructure company and a $308 million investment in space vehicle developer .

Methodology

We tracked the largest announced rounds in the SA国际传媒 database that were raised by U.S.-based companies for the period of Sept. 12-18, 2026. Although most announced rounds are in the database, there may be a small time lag, as some rounds are reported late in the week.

Illustration:

This tracker includes layoffs conducted by U.S.-based companies or those with a strong U.S. presence and is updated at least bi-weekly. We鈥檝e included both startups and publicly traded, tech-heavy companies. We鈥檝e also included companies based elsewhere that have a sizable team in the United States, such as , even when it鈥檚 unclear how much of the U.S. workforce has been affected by layoffs.

Layoff and workforce figures are best estimates based on reporting. We source the layoffs from media reports, our own reporting, social media posts and , a crowdsourced database of tech layoffs.

We recently updated our layoffs tracker to reflect the most recent round of layoffs each company has conducted. This allows us to quickly and more accurately track layoff trends, which is why you might notice some changes in our most recent numbers.

If an employee headcount cannot be confirmed to our standards, we note it as 鈥渦nclear.鈥�

U.S. venture-backed technology听1 companies have secured nearly $90 billion in domestic public offerings this year, per SA国际传媒 data. That鈥檚 already the second-highest annual tally on record, and we鈥檝e still got a few months to go.

However, virtually all the money went to two companies. alone accounted for 83% of the $90 billion raised this year, while AI infrastructure company scooped up another 6%. A potential offering from , meanwhile, could be even bigger.

The remaining field is comparatively modest. Just 21 other venture-backed technology companies went public this year in sizable or offerings 2, per SA国际传媒 data. Collectively, their offerings, which include traditional IPOs and SPAC deals, pulled in less than $10 billion.

This small cohort is intriguing for what it excludes as well as what it includes. Enterprise software, long a staple industry among venture-backed IPOs, was essentially a no-show this year. Energy, defense and space tech, by contrast, were well-represented. We also saw smaller offerings from other sectors, including medical devices and consumer-facing startups.

Here are some of the key findings in more detail:

Energy powers the most IPOs: About a quarter of this year鈥檚 tech startup offerings hail from the energy sector. The largest of these was from geothermal energy provider . Several nuclear power-focused startups also made their debuts, including and , developers of small modular nuclear reactors, as well as , focused on advanced nuclear fuel.

A dash of quantum, defense, aerospace, devices and consumer: Beyond energy, quantum computing company delivered one of the year鈥檚 larger debuts, as did equipment rental platform . Defense tech and aerospace were also strong performers, with offerings from satellite intelligence provider and spacecraft developer . And on the consumer front, e-bike and scooter platform finally made its market entrance, albeit at a valuation below its one-time .

An IPO SaaS-pocalipse: But what about SaaS? Mostly MIA. The paucity of enterprise software offerings this year isn鈥檛 entirely surprising given the impact of AI on the sector. VCs are pouring capital into a newer generation of AI-first platforms in legal tech, accounting and other enterprise software sectors. Existing SaaS unicorns are also moving fast to incorporate more AI in their offerings.

One end result is there are an awful lot of SaaS unicorns and former unicorns that have concluded this year is not the time to pursue an IPO.

Winner-takes-almost-all

Another end result is that investment returns are looking more concentrated than ever.

Of course, winning big or not at all is far from a new thing in the startup world. Tech venture returns have always been propped up largely by a few enormous wins, with the remainder of portfolio companies producing either losses or smaller profitable exits. But lately, the winner-take-almost-all-the-IPO-proceeds tilt is more pronounced than ever.

The pipeline of tech companies that have filed for future IPOs doesn鈥檛 offer much consolation that this pattern will change. Giant potential market debuts from Anthropic and still dominate IPO chatter. Enterprise SaaS offerings do not.

One of the strangest things about the current AI cycle is just how fast the math changes for the people building it. You can be a 20-something founder who feels like you are still in the warm-up phase of your career, yet on paper your equity is already life changing. Or a mid-level engineer who went from holding startup options to staring at a substantial personal balance sheet practically overnight.

The gap between life experience and the sudden reality of managing serious wealth is widening as AI-native companies reach major valuations faster and private company liquidity arrives earlier.

A of more than 3,400 founders and senior leaders across 20 countries found that AI-native startups are reaching billion-dollar valuations in about 3.5 years, roughly half the time it took before generative AI. They are doing it with about half the staff.

We have seen an even more compressed version firsthand. We recently advised founders who went from launching their company to a major liquidity event in less than a year.

When the money outpaces the mindset

For decades, tech wealth followed a more predictable script. Significant personal wealth often accumulated alongside a long career. Equity vested over years, responsibilities grew and additional grants often followed. If everything went right, an acquisition or IPO marked a visible transition into a very different financial reality.

Today, that boundary is much less clear. AI capabilities allow companies to grow at a much faster pace.

A young founder can suddenly face questions that used to come much later in life. What are their long-term personal goals? What should the new capital be used for? What does financial independence mean for someone who may still be figuring out what they want their life to look like?

These are not always questions that can be answered overnight.

Compounding this is the fact that one doesn鈥檛 have to wait for an IPO to de-risk. Tender offers and secondary transactions allow founders and employees to turn part of their equity into cash while the company remains private.

Take as an example. While still only 3 years old, the company authorized a $100 million secondary sale for staff at a $6.6 billion valuation. By February 2026, it had at an $11 billion valuation.

For someone inside a company moving at that speed, the sequence can look very different from the traditional startup script. It is a dizzying loop of grants, valuations and a sudden liquidity window. All of this can happen long before an IPO.

Flexibility is the name of the game

A sudden liquidity event can make financial independence a realistic goal. It may make buying a home possible, even while someone is still single or has no idea where they want to live long term. It may allow them to take care of parents or fund another entrepreneurial chapter.

The pace of these cycles can also be contagious. Opportunities seem to be everywhere. At the same time, a founder may still be taking substantial risks with the current venture and have very little idea what life will look like in five years.

When we advise technology executives and founders in this position, we try to leave room for several possible paths while the broader picture is still developing. Some capital may eventually support long-term family security. Some may need to remain available for opportunities or life changes that do not exist today.

A future business endeavour, a career change, a relocation to another country, or other less conventional ideas can change the picture again. Some of these moves can be made today, but others need time to develop.

A company may compress 10 years of growth into three, but people cannot compress 10 years of life into three. Ignoring that gap is where real risk can build.

Valuations and liquidity can move incredibly fast. Decisions about family wellbeing, security, career and the future still move at a human pace. Your financial architecture needs to respect the difference.

Startups across sales, marketing and customer management have raised $7.5 billion so far this year, according to SA国际传媒 data. The largest rounds span everything from advertising and customer data to sales software, e-commerce and customer support 鈥� reflecting just how many companies are still trying to build a better way to market and sell.

The broad trend: Investors are making far fewer bets on sales and marketing startups than immediately before and after the COVID-19 pandemic, but they鈥檙e still writing checks into the space.

Unsurprisingly, AI-focused companies are capturing a much larger share of funding than during the prior peak, with most sales, marketing and CRM investment going to companies in SA国际传媒 AI-related categories.

The numbers: So far in 2026, startups in sales, marketing and CRM have raised $7.5 billion globally across 830 funding rounds, SA国际传媒 data shows. At the current pace, funding could finish near the $9.3 billion raised in both 2023 and 2024, although potentially below last year鈥檚 $11.1 billion. Deal volume, meanwhile, is on track to fall for a fourth consecutive year 鈥� pointing to a market where investors are putting more money into fewer companies.

Funding in recent years remains far below past levels. In 2022, for example, funding in the sector topped $27 billion, and in 2021, it totaled nearly $41 billion.

Notable deals

The year鈥檚 largest funding recipient so far was, which raised more than $1 billion in a June Series E from , , and . The San Francisco-based marketing measurement company, whose products now include AI agents that analyze marketing data and automate tasks, was valued at $2.7 billion.

Restaurant financing and rewards platform announced $450 million in new capital in February. The Austin-based company did not identify a lead investor or disclose a valuation.

In January, AI-native customer service company raised a $350 million Series D led by . The Berlin-based company develops AI agents that handle customer conversations by phone and other channels. The financing tripled its valuation to $3 billion.

Meanwhile, , an online marketplace for digital products, communities and courses, received a $200 million strategic investment from in February. The deal valued the New York-based company at $1.6 billion.

Another larger deal went to Dubai-based property listings platform , which announced a $170 million equity investment in January. The company uses AI in products including home valuations and tools that help real estate agents improve and prioritize listings. led the deal, with participation from another UAE sovereign wealth fund and existing investor . The company did not disclose a valuation.

On Sept. 9,听 AI-powered sales automation startup announced it had raised a $115 million Series D at a $7.1 billion valuation. This was more than double the $3.1 billion valuation it achieved when it raised a $100 million Series C in August 2025. Wellington led the latest round, with participation from , , 鈥檚 a16z Perennial wealth management arm, , and others. The company says the raise followed 4x revenue growth in 2025. It also told SA国际传媒 News that it’s on track to hit $200 million in ARR this quarter, and $240 million by the end of the fiscal year.

Exits

The sector has produced one notable public offering, but most exits are coming through acquisitions as larger companies buy specialized sales and marketing products to add to their existing platforms, SA国际传媒 data shows.

, a Redwood City, California-based mobile advertising and app-marketing company, began trading on the in June. It initially sold 19 million shares at $23 each, raising $437 million. The IPO valued Liftoff at $3.83 billion, based on the outstanding shares disclosed in its IPO prospectus.

There have been a number of M&A deals this year in the sector, too, though in most cases, the acquisition price was not disclosed.

The largest known deal was Dutch payments giant acquisition of , a Berlin-based loyalty and promotions platform, in July for about $880 million. Talon had previously raised over $120 million in venture funding.

Other startup M&A deals in the marketing and sales arena in 2026 include:

• In July, acquired Seattle-based sales intelligence startup to add information about prospective buyers to its sales products.
• In June, agreed to acquire , whose software helps companies identify and contact people visiting their websites.
• Sales platform acquired , which helps sales teams identify prospective customers based on product use and other signals, in March.
• acquired the Estonian startup , whose software connects sales and marketing data, in August.
• acquired India-based marketing intelligence startup in September through a team and technology deal.

Funding is down from peak years, but it鈥檚 clear investors haven鈥檛 lost interest in sales and marketing startups. However, they are putting more money into fewer of them. Companies that help businesses find customers, increase sales, or retain existing business are still landing big checks and attracting buyers. But with acquisitions far more common than IPOs, a public-market exit remains much harder to come by.

Always-busy was the most active backer of U.S.-based startups by deal count, while led or co-led the most rounds of $5 million or more, SA国际传媒 data shows.

Chip giant , meanwhile, sharply accelerated its dealmaking, ranking among the most active and highest-spending investors for the month. The chip giant participated in nine disclosed rounds of at least $5 million 鈥� marking its busiest month for investing since at least the beginning of 2025 鈥� and led or co-led financings collectively valued at $1.3 billion.

The flurry of activity came as global venture funding reached $42 billion in August, up 122% year over year, with seven companies raising billion-dollar-plus rounds last month.

Below, we rank August鈥檚 most active startup investors across several categories, including lead backers, prolific venture dealmakers, highest spenders and seed investors.

Active lead investors

San Francisco-based General Catalyst ranked as the most active lead investor in rounds of $5 million or more, leading or co-leading five such deals. Its largest was the $1.1 billion Series A for, which provides custom AI fine-tuning for businesses. General Catalyst also led or co-led a $116 million Series E for, along with three seed rounds ranging from $10 million to $25 million, SA国际传媒 data shows.

, and tied for second, with four lead or co-lead deals each.

The scale of those rounds varied considerably. The four deals that Andreessen led or co-led totaled more than $1.15 billion, driven by an $800 million Series C for defense tech company and a $300 million Series A for AI infrastructure startup .

Sequoia鈥檚 four led or co-led deals totaled $1.3 billion, including a $1 billion Series B for nuclear energy startup .

Busiest venture investors

When we widen the ranking to include both lead and non-lead participation in rounds of $5 million or more, Y Combinator once again takes the top spot.

The accelerator participated in at least 18 such deals in August, per SA国际传媒 data. As we鈥檝e noted in previous rankings, Y Combinator commonly invests as a non-lead backer in follow-on rounds for companies that previously went through its program.

Andreessen Horowitz ranked second with 13 deals, followed by General Catalyst with 10. and Nvidia tied for fourth with nine each.

Nvidia鈥檚 rise in the investor rankings is particularly notable. The Santa Clara, California-based chip giant participated in only four U.S. rounds of $5 million or more in July and one in August 2025. Seven of its nine qualifying investments last month went to companies categorized as AI-focused in SA国际传媒, including River AI, , , and .

The August burst extends a notable increase in Nvidia鈥檚 venture dealmaking pace this year. SA国际传媒 data shows that by mid-August, it had participated in a record 59 known startup funding rounds in 2026, already surpassing its 53 investments in all of 2025. It had also led or co-led at least 11 private-company financings this year, underscoring its growing role as both a technology supplier to and financial backer of the AI startup ecosystem.

and Sequoia were next in our August rankings, each with seven U.S. startup investments of $5 million or more. RA Capital鈥檚 portfolio reflected its life sciences focus, with August deals including , , , and .

Highest-spending investors

The rankings change again when we look at lead investors associated with the highest aggregate deal values.

For August, was the apparent spendiest lead investor, thanks to its role leading 鈥� $5 billion deal. The round, the month鈥檚 largest, valued the data and AI company at $190 billion.

and followed, each leading or co-leading rounds with an aggregate value of $2.37 billion, as both were listed as lead investors in defense manufacturing startup鈥檚 $1.37 billion Series D and home battery provider鈥檚 $1 billion Series D.

Nvidia and Sequoia came next, each with $1.3 billion in led or co-led rounds. Nvidia鈥檚 total came from Poolside鈥檚 $1 billion financing and Volta鈥檚 $300 million Series A, while Sequoia led or co-led four rounds, topped by the Valar Atomics financing.

General Catalyst and Andreessen also crossed the $1 billion mark, with approximately $1.26 billion and $1.15 billion, respectively, in aggregate led round value.

As always, this is an approximation of spending rather than a tally of capital actually contributed. Investors rarely disclose how much each participant put into a round, although lead investors generally contribute a substantial share.

Seed dealmakers

At seed, Y Combinator was again the most prolific investor, backing at least 12 U.S.-headquartered companies in August.

ranked second with eight seed investments, all announced as part of the same August cohort. and followed with six seed deals each, while 1听recorded five. (It’s important to note that seed rankings are especially subject to change, since smaller financings often take longer to be reported and added to the SA国际传媒 dataset.)

Big checks, familiar names

August鈥檚 rankings tell a now-familiar story: A relatively small group of large venture firms continues to dominate by deal count, while a handful of megadeals determines who tops the spending ranks. But Nvidia鈥檚 acceleration this year also illustrates how corporate investors 鈥� particularly those with a direct stake in the AI ecosystem 鈥� are becoming increasingly prominent alongside traditional venture firms.

If your pitch still leads with “we use AI,” you’re describing infrastructure, not a business. Consider that 97% of the products nominated for this year鈥檚 Product Awards are deeply integrated with AI, highlighting the extent to which the days of AI as a differentiator are officially gone.

The real moat investors are seeking today is something many founders cannot identify: What will survive a well-funded competitor who could launch tomorrow with a better model.

We analyzed SA国际传媒 data on 576 venture-backed, AI B2B companies that raised $50 million-plus rounds since the start of 2025 using Hamilton Helmer鈥檚 framework and layered in insights from Products That Count鈥檚 600,000-plus product leader community.

The data gives a clear answer: When building is nearly free, the only moats that hold are those that a model cannot generate.

Two of them work without requiring you to out-raise . Two of them are traps. And one isn’t a game most founders are playing.

Counter-positioning: The moat that costs nothing to defend

Counter-positioning is what happens when a newcomer builds a business model so structurally different that the incumbent can’t copy it without destroying their own economics. versus is the canonical example. Blockbuster could have matched the subscription model, but doing so would have gutted late-fee revenue, which kept their stores alive. So they didn’t, until it was too late.

In the AI era, this power is rare and underutilized. Only 5% of companies in our dataset leverage counter-positioning. Investors price that scarcity at a median enterprise value of 5.3x per dollar raised 鈥� the highest multiple of any power in the analysis.

The pattern shows up in vertically integrated AI insurers that sell directly to employers, a model traditional brokers can’t replicate without cannibalizing their own relationships and underwriting margins. It shows up in AI-native revenue management systems that would gut the high-margin consulting revenue legacy vendors depend on if those vendors tried to match them.

The incumbent sees the threat. They choose not to respond. That rational inaction is the moat.

For founders, the diagnostic question is this: Could a well-resourced incumbent copy your model if they wanted to? The right signal is answering “technically yes, but it would cost them more than it would cost us to build.鈥�

Network economies: The moat that builds itself

Network economies arise when a product becomes more valuable to each user as more users join. At scale, this tends toward winner-take-all outcomes within the network’s boundaries, whether in geography, professional context or industry vertical. is the textbook case: More recruiters attract more candidates, which in turn attract more professionals, which in turn attract more recruiters.

In our dataset, network economies appear in only 5% of companies, but command a 4.2x multiple. That makes it the most capital-efficient path to a strong valuation premium available to founders today.

The B2B variant here is particularly underappreciated. Rather than individual users as nodes, the network connects companies: brands to factories, advertisers to audiences, platforms to partners. Every new participant makes the network more valuable for every existing participant.

The data that accumulates across those interactions 鈥� costing, production cycles, audience behavior 鈥� compounds in ways that become progressively harder to replicate.

Getting both sides of a two-sided market to commit simultaneously is hard. But founders who solve the cold-start problem own something that a well-funded competitor with a better model still cannot buy.

What looks like a moat but isn’t?

At 44%, cornered resources like proprietary data, unique IP and exclusive access command the second-highest prevalence in our dataset. But they also have the worst multiple: 2.6x. Because investors have watched too many proprietary datasets get eroded by foundation models and synthetic data, if a data advantage doesn鈥檛 compound in ways that get harder to replicate over time, it can鈥檛 be considered a moat.

Switching costs are the most crowded power at 37%, and look like a moat because customers really don’t leave.

But the cost of building them creates a problem, because the requirement for deep enterprise entanglement 鈥� baked-in instrumentation, institutional memory, rearchitecture risk 鈥� means expensive sales cycles before the stickiness kicks in. The multiple is comparable to network economies (4x), but the capital required to reach it is roughly 10x higher. It’s a viable path for founders who build a product-led growth motion to reduce that cost, or who engineer a reason for users to collaborate on the platform, converting switching costs into network economies over time.

Scale economies are not the game most founders are playing. The median multiple, excluding OpenAI and , collapses from 6.1x to 3.2x, and 88% of the category’s capital belongs to those two companies. Believing your unit economics improve with growth does not equate to building a scale moat. The gap between the two is measured in billions of dollars that most startups will never raise.

The only question that matters

Every company in this dataset has AI in its product. The ones commanding premium multiples have built something underneath the AI that a model cannot generate on its own.

That something is structural. It lies in the business model design or the network architecture, rather than model quality, feature set or data volume. It answers the question every founder should be able to state in one sentence: What about my business would survive a competitor who starts today with more capital and a better model?

Methodology

The SA国际传媒 Unicorn Board is a curated list that includes private unicorn companies with post-money valuations of $1 billion or more and is based on SA国际传媒 data. New companies are as they reach the $1 billion valuation mark as part of a funding round.听

The unicorn board does not reflect internal company valuations 鈥� such as those set via a 409a process for employee stock options 鈥� as these differ from, and are more likely to be lower than, a priced funding round. We also do not adjust valuations based on investor writedowns, which change quarterly, as different investors will not value the same company consistently within the same quarter.听

Funding to unicorn companies includes all private financings to companies that are tagged as unicorns, as well as those that have since graduated to .听

Exits analyzed here only include the first time a company exits.听

Please note that all funding values are given in U.S. dollars unless otherwise noted. SA国际传媒 converts foreign currencies to U.S. dollars at the prevailing spot rate from the date funding rounds, acquisitions, IPOs and other financial events are reported. Even if those events were added to SA国际传媒 long after the event was announced, foreign currency transactions are converted at the historic spot price.

led the round, with participation from co-leads Scaleup Europe Fund, managed by , and existing investor .

The financing comes nearly one year to the day after Mistral鈥檚 $2 billion Series C, which valued the company at $13.7 billion. Mistral has now raised $7.5 billion since its 2023 inception.

Mistral鈥檚 new raise means it retains its spot as the most highly valued foundation model company out of Europe. There are currently seven private frontier labs valued above $20 billion on The SA国际传媒 Unicorn board 鈥� eight including China鈥檚 , which is also building its own model 鈥� though the rest are all based in the U.S. and China.

In a statement, the company says the new capital will 鈥渟ignificantly expand Mistral’s frontier research鈥� and help it 鈥渆xpand infrastructure and accelerate鈥� its commercial growth and international footprint. Mistral currently operates across 20 countries and counts more than 125 global enterprises as customers, including , , and .

Mistral builds AI models for tasks such as generating text, writing code and analyzing documents, putting it in competition with U.S. companies including , and .

However, unlike many of its U.S. rivals, Mistral touts greater control for businesses by offering models they can customize and run on their own systems rather than relying entirely on a third-party cloud provider.

Europe鈥檚 VC momentum

This year has marked a turning point for European venture funding. In Q2, Europe posted its strongest quarter in four years for venture funding, SA国际传媒 data shows. All told, Europe-based startups raised $24 billion in the quarter, up around a third quarter over quarter and two-thirds higher than the $14.4 billion raised in Q2 2025.

At the time of Mistral鈥檚 $2 billion Series C, that raise represented the largest venture round ever raised by a European AI company.

This latest round has now eclipsed that, and several other large AI-related deals in Europe have also closed this year. They include London-based Google spinoff , which raised a $2.1 billion Series B in May led by and AI data center provider , which raised a $2 billion Series C at a $14.6 billion valuation in March co-led by and . (It has also since raised several billion in debt financing, per SA国际传媒.)
