San Francisco-based AI startup Writer debuted a large artificial intelligence model on Wednesday to compete with enterprise offerings from OpenAI, Anthropic and others. But, unlike some of those competitors, it doesn’t need to spend as much to train its AI.
The company told CNBC it spent about $700,000 to train its latest model, including the data and GPUs, compared to the millions of dollars competing startups spend to build their own models. Its strategy has caught the attention of investors.
Writer is raising up to $200 million at a $1.9 billion valuation, according to a source familiar with the situation who spoke with CNBC. That’s nearly quadruple the company’s valuation last September, when it raised $100 million at a valuation of more than $500 million.
The company cuts costs using synthetic data, or data created by AI. It’s designed to mimic the real-world information that’s usually fed into models without compromising privacy and is becoming a more popular method for training.
A study by AI researchers revised in June found that if current AI development trends continue, tech companies will “fully exhaust” the publicly available training data between 2026 and 2032, writing that “human-generated public text data cannot sustain scaling beyond this decade.”
Amazon has used synthetic data in training Alexa, Meta has used it to fine-tune its Llama models and Microsoft-backed OpenAI is incorporating it into its models, according to job descriptions posted by the company. Some experts, however, have warned that synthetic data should be used cautiously, as it has the potential to degrade model performance and exacerbate existing biases.
Waseem Alshikh, Writer’s co-founder and CTO, told CNBC that Writer has been working on its synthetic data pipeline for years.
“There’s some confusion in the industry about the definition of ‘synthetic’ data,” Alshikh said. “To be clear, we don’t train our models on fake or hallucination data, and we don’t use a model to generate random data… We take real, factual data and convert it to synthetic data that is specifically structured in a clearer and cleaner way for model training.”
The company’s generative AI allows corporate clients to use its large language models (LLMs) to generate human-sounding text for anything from LinkedIn posts to job descriptions to mission statements, as well as data analysis and summarization. The company has more than 250 enterprise customers, including Accenture, Uber, Salesforce, L’Oreal and Vanguard, who use the tech across sectors like support, IT, operations, sales, and marketing.
The generative AI market is poised to top $1 trillion in revenue within a decade. To date in 2024, investors have pumped $26.8 billion into 498 generative AI deals, according to PitchBook, and companies in the sector raised $25.9 billion in 2023, up more than 200% from 2022.
Cryptocurrencies and several stocks tied to the ecosystem rose Wednesday as investors dismissed a snag in what was expected to be a winning week for crypto regulation.
Bitcoin was last higher by 2% at $119,114.79, according to Coin Metrics, while ether rose 3% to $3,156.
Shares of stablecoin issuer Circle added more than 1% premarket and crypto services firm Coinbase gained about 0.5%, after both closed lower in the previous session. Ether treasury stocks continued their rally: BitMine surged 24%, while SharpLink jumped 14% and Bit Digital gained 5%.
On Tuesday, prices dipped briefly after the House failed to advance two key pieces of legislation for the crypto industry: the stablecoin bill known as the GENUIS Act, which has already passed the Senate, and the broader and far more complex market structure bill known as the CLARITY Act. Industry players including Coinbase hoped to see these bills move forward together, despite the latter one still awaiting a vote in the House.

Oppenheimer analyst Owen Lau told CNBC the stock reaction was overblown and framed the passage of the bills as a matter of “when” rather than an “if.”
“It’s not such bad news which is why the stocks [Coinbase and Circle] recovered in late trading,” he said. “Both stocks may be under pressure until we get the vote but these bills will eventually get passed after these negotiations.”
It doesn’t ultimately matter how they get passed – separately or bundled – “in terms of the terminal value … but the stock could react more positively if all three bills get combined,” and the market “would lose three or four months of uncertainty,” Lau added.
President Donald Trump said in a social media post Tuesday night that several of the House Republicans who kept the bills from advancing had changed their minds following a White House meeting and will now vote to move the legislation forward.
In its current form, the GENIUS Act would restrict stablecoin issuers from paying users interest, which would reinforcing the importance of Ethereum – a network favored by institutions that supports a significant amount of activity and applications, including stablecoins – in the ecosystem.

Ether (ETH) has doubled in price in the last three months
However, ether’s recent rally, driven by momentum and speculative positioning among the boom in stablecoin interest and ether treasuries, has not been supported by fundamentals.
“Active addresses remain flat, network revenue is unchanged, and gas [transaction] fees have only ticked up slightly,” according to 10x Research’s Markus Thielen. Ether has doubled in price in the last three months.
Bitcoin, whose price slipped this week due to more than $360 million in long liquidations Monday, also dropped after the crypto bills were halted, but recovered soon after. On Monday, the flagship cryptocurrency reached an all-time high above $120,000.
Bitcoin ETFs saw $402.99 million in inflows from institutions on Tuesday, while ether funds raked in $192.3 million, according to SoSoValue.

ASML reported second-quarter earnings that beat estimates with the its key net bookings figure ahead of consensus.
However, the chip equipment giant missed analyst expectations for revenue guidance in the current quarter and warned of the possibility of no growth ahead.
Here’s how ASML did versus LSEG consensus estimates for the second quarter:
Net sales: 7.7 billion euros ($8.95 billion) versus 7.52 billion euros expected
Net profit: 2.29 billion euros vs 2.04 billion euros expected
In its own previous forecast issued in April, ASML had said it expected second-quarter net sales of between 7.2 billion euros and 7.7 billion euros. In a pre-recorded interview posted on ASML’s website, the company’s Chief Financial Officer Roger Dassen said the beat was due to revenue from upgrading currently deployed machines as well as tariffs having a “less negative” impact than anticipated.
Analysts anticipated net bookings — a key indicator of order demand — would come in at 4.19 billion euros over the April-June stretch. ASML reported net bookings of 5.5 billion euros.
ASML is one of the most important semiconductor supply chain companies in the world. It makes extreme ultraviolet lithography (EUV) machines, which are required to manufacture the most advanced chips in the world, such as those designed by Apple and Nvidia.
Like many companies in the semiconductor industry, ASML has been grappling with uncertainty created by U.S. tariff policy.
The company forecast third-quarter revenue of between 7.4 billion euros and 7.9 billion euros, which was shy of market expectations of 8.3 billion euros.
ASML said it expects full-year 2025 net sales to grow 15%, narrowing its guidance from a previously announced forecasts of between 30 billion euros to 35 billion euros.
However, the Dutch tech giant was less certain about the outlook for 2026.
“Looking at 2026, we see that our AI customers’ fundamentals remain strong,” ASML CEO Christophe Fouquet said in a statement.
“At the same time, we continue to see increasing uncertainty driven by macro-economic and geopolitical developments. Therefore, while we still prepare for growth in 2026, we cannot confirm it at this stage.”
The Veldhoven, Netherlands-headquartered company has released its next generation EUV tools known as High NA, which stands for high numerical aperture. These machines, which are larger than a double-decker bus and can cost more than $400 million each, are key to ASML’s future growth plans.

The U.S. Food and Drug Administration on Tuesday published a warning letter addressed to the wrist wearable company Whoop, alleging it is marketing a new blood pressure feature without proper approvals.
The letter centers around Whoop’s Blood Pressure Insights (BPI) feature, which the company introduced alongside its latest hardware launch in May.
Whoop said its BPI feature uses blood pressure information to offer performance and wellness insights that inform consumers and improve athletic performance.
But the FDA said Tuesday that Whoop’s BPI feature is intended to diagnose, cure, treat or prevent disease — a key distinction that would reclassify the wellness tracker as a “medical device” that has to undergo a rigorous testing and approval processes.
“Providing blood pressure estimation is not a low-risk function,” the FDA said in the letter. “An erroneously low or high blood pressure reading can have significant consequences for the user.”
A Whoop spokesperson said the company’s system offers only a single daily estimated range and midpoint, which distinguishes it from medical blood pressure devices used for diagnosis or management of high blood pressure.
Whoop users who purchase the $359 “Whoop Life” subscription tier can use the BPI feature to get daily insights about their blood pressure, including estimated systolic and diastolic ranges, according to the company.
Whoop also requires users to log three traditional cuff-readings to act as a baseline in order to unlock the BPI feature.
Additionally, the spokesperson said the BPI data is not unlike other wellness metrics that the company deals with. Just as heart rate variability and respiratory rate can have medical uses, the spokesperson said, they are permitted in a wellness context too.
“We believe the agency is overstepping its authority in this case by attempting to regulate a non-medical wellness feature as a medical device,” the Whoop spokesperson said.

High blood pressure, also called hypertension, is the number one risk factor for heart attacks, strokes and other types of cardiovascular disease, according to Dr. Ian Kronish, an internist and co-director of Columbia University’s Hypertension Center.
Kronish told CNBC that wearables like Whoop are a big emerging topic of conversation among hypertension experts, in part because there’s “concern that these devices are not yet proven to be accurate.”
If patients don’t get accurate blood pressure readings, they can’t make informed decisions about the care they need.
At the same time, Kronish said wearables like Whoop present a “big opportunity” for patients to take more control over their health, and that many professionals are excited to work with these tools.
Understandably, it can be confusing for consumers to navigate. Kronish encouraged patients to talk with their doctor about how they should use wearables like Whoop.
“It’s really great to hear that the FDA is getting more involved around informing consumers,” Kronish said.

Whoop is not the only wearable manufacturer that’s exploring blood pressure monitoring.
Omron and Garmin both offer medical blood pressure monitoring with on-demand readings that fall under FDA regulation. Samsung also offers blood-pressure-reading technology, but it is not available in the U.S. market.
Apple has also been teasing a blood pressure sensor for its watches, but has not been able to deliver. In 2024, the tech giant received FDA approval for its sleep apnea detection feature.
Whoop has previously received FDA clearance for its ECG feature, which is used to record and analyze a heart’s electrical activity to detect potential irregularities in rhythm. But when it comes to blood pressure, Whoop believes the FDA’s perspective is antiquated.
“We do not believe blood pressure should be considered any more or less sensitive than other physiological metrics like heart rate and respiratory rate,” a spokesperson said. “It appears that the FDA’s concerns may stem from outdated assumptions about blood pressure being strictly a clinical domain and inherently associated with a medical diagnosis.”
The FDA said Whoop could be subject to regulatory actions like seizure, injunction, and civil money penalties if it fails to address the violations that the agency identified in its letter.
Whoop has 15 business days to respond with steps the company has taken to address the violations, as well as how it will prevent similar issues from happening again.
“Even accounting for BPI’s disclaimers, they do not change this conclusion, because they are insufficient to outweigh the fact that the product is, by design, intended to provide a blood pressure estimation that is inherently associated with the diagnosis of a disease or condition,” the FDA said.
