In a Brooklyn lab stuffed with 3D printers and a makeshift pickleball court, employees at a brain interface startup called Synchron are working on technology designed to transform daily life for people with paralysis.
The Synchron Switch is implanted through the blood vessels to allow people with no or very limited physical mobility to operate technology such as cursors and smart home devices using their mind. So far, the nascent technology has been used on three patients in the U.S. and four in Australia.
“I’ve seen moments between patient and partner, or patient and spouse, where it’s incredibly joyful and empowering to have regained an ability to be a little bit more independent than before,” Synchron CEO Tom Oxley told CNBC in an interview. “It helps them engage in ways that we take for granted.”
Founded in 2012, Synchron is part of the burgeoning brain-computer interface, or BCI, industry. A BCI is a system that deciphers brain signals and translates them into commands for external technologies. Perhaps the best-known name in the space is Neuralink, thanks to the high profile of founder Elon Musk, who is also the CEO of Tesla, SpaceX and Twitter.
But Musk isn’t the only tech billionaire wagering on the eventual transition of BCI from radical science experiment to flourishing medical business. In December, Synchron announced a $75 million financing round that included funding from the investment firms of Microsoft co-founder Bill Gates and Amazon founder Jeff Bezos.
‘More scalable’
In August 2020, the Food and Drug Administration granted Synchron the Breakthrough Device designation, which is for medical devices that have the potential to provide improved treatment for debilitating or life-threatening conditions. The following year, Synchron became the first company to receive an Investigational Device Exemption from the FDA to conduct trials of a permanently implantable BCI in human patients.
Synchron is enrolling patients in an early feasibility trial, which aims to show that the technology is safe to put in humans. Six patients will be implanted with Synchron’s BCI during the study, and Chief Commercial Officer Kurt Haggstrom said the company is currently about halfway through.
The company has no revenue yet, and a spokesperson said Synchron isn’t commenting on how much the procedure will eventually cost.
While many competitors have to implant their BCIs through open-brain surgery, Synchron relies on a less invasive approach that builds on decades of existing endovascular techniques, the company said.

Synchron’s BCI is inserted through the blood vessels, which Oxley calls the “natural highways” into the brain. Synchron’s stent, called the Stentrode, is fitted with tiny sensors and is delivered to the large vein that sits next to the motor cortex. The Stentrode is connected to an antenna that sits under the skin in the chest and collects raw brain data that it sends out of the body to external devices.
Peter Yoo, senior director of neuroscience at Synchron, said since the device is not inserted directly into the brain tissue, the quality of the brain signal isn’t perfect. But the brain doesn’t like being touched by foreign objects, Yoo said, and the less invasive nature of the procedure makes it more accessible.
“There’s roughly about 2,000 interventionalists who can perform these procedures,” Yoo told CNBC. “It’s a little bit more scalable, compared to, say, open-brain surgery or burr holes, which only neurosurgeons can perform.”

For patients with severe paralysis or degenerative diseases such as amyotrophic lateral sclerosis, or ALS, Synchron’s technology can help them regain their ability to communicate with friends, family and the outside world, whether through typing, texting or even accessing social media.
Patients can use Synchron’s BCI to shop online and manage their health and finances, but Oxley said what often excites them the most is text messaging.
“Losing the ability to text message is incredibly isolating,” Oxley said. “Restoring the ability to text message loved ones is a very emotional restoration of power.”
In December 2021, Oxley handed over his Twitter account to a patient named Philip O’Keefe, who has ALS and struggles to move his hands. About 20 months earlier, O’Keefe was implanted with Synchron’s BCI.
“hello, world! Short tweet. Monumental progress,” O’Keefe tweeted on Oxley’s page, using the BCI.
Synchron’s technology has caught the attention of its competitors. Musk approached the company to discuss a potential investment last year, according to a Reuters report. Synchron declined to comment about the report. Neuralink didn’t respond to a request for comment.
Neuralink is developing a BCI that’s designed to be inserted directly into the brain tissue, and while the company is not testing its device in humans yet, Musk has said he hopes it will do so this year.
Haggstrom said his company’s funding will help accelerate Synchron’s product development and push it toward a pivotal clinical trial that would bring the company closer to commercialization.
Khosla Ventures partner Alex Morgan, who led an earlier financing round, said that while Synchron’s device may seem like something out of science fiction, it’s grounded in “real science” and is already making a significant difference in patients’ lives.
“Synchron is actually helping people as of right now, today,” he said in an interview. “That, to me, is really exceptional.”

In January, the medical journal JAMA Neurology published the peer-reviewed, long-term safety results from a trial of Synchron’s BCI system in Australia. The study found that the technology remained safe and didn’t deteriorate in signal quality or performance over a 12-month period.
“That was a huge publication for us,” Haggstrom said.
Haggstrom said commercialization is key for all the players in the industry.
“I always like to be competitive, and so for me, being first to market is critical,” Haggstrom said. “We meet future patients to talk to about their needs and stuff, and so when you see that, and you talk to these families and the caregivers, you want to race as fast as you can to provide them assistance in their daily life.”

Commuters in and around San Francisco rode into work for free on Tuesday morning due to an outage in the Clipper card system, which is used to handle payments for train, bus and ferry rides.
“ATTENTION: The Clipper system is experiencing an outage on all operators this morning,” the Bay Area Clipper account wrote in a post on X. “Please be prepared to pay your fare with another form of payment if required by your transit agency.”
Many buses were waving commuters on without asking for payment, and at Bay Area Rapid Transit (BART) train stations, the faregates were open, allowing travelers to walk through for free.
Clipper is owned by the Metropolitan Transportation Commission, which manages transportation for the nine-county Bay Area. The service is used by hundreds of thousands of tech workers in San Francisco and Silicon Valley.
The MTC website said there were 1.35 million unique Clipper cards — physical and digital — used in May, the highest monthly toll for the year and the most since December 2019, before the pandemic. A fact sheet from the MTC says Clipper is used by 800,000 transit riders a day across the region.

BART, in particular, has undergone dramatic changes in recent years, most notably installing fare gates starting in late 2023, with full deployment expected to be completed by the end of this year.
In the first five months of the year, average BART station exits totaled between 170,000 and 182,000 a month, according to its website. Those numbers are way down from the pre-pandemic days of 2019, when averages were generally above 400,000 a month.
The MTC has plans to roll out an updated system called Clipper 2.0, which it says will be a “customer-focused, cost-effective fare collection system” with a “flexible platform for future fare structures.” Features include use across the various mobile operating systems, updated communication and “expanded retail, online and mobile sales.”
The update, however, has been routinely delayed, leading to tense confrontations at recent Clipper executive board meetings.
Corporate treasuries have surpassed ETFs in bitcoin buying for a third consecutive quarter as more companies try to benefit from the MicroStrategy playbook in a more crypto-friendly regulatory environment.
Public companies acquired about 131,000 coins in the second quarter, growing their bitcoin balance 18%, according to data provider Bitcoin Treasuries. ETFs showed an 8% increase or about 111,000 BTC in the same period.
“The institutional buyer who is getting exposure to bitcoin through the ETFs are not buying for the same reason as those public companies who are basically trying to accumulate bitcoin to increase shareholder value at the end of the day,” said Nick Marie, head of research at Ecoinometrics.
Public company bitcoin holdings increased 4% in April, a tumultuous month after the market was rocked by President Donald Trump’s initial tariffs announcement, versus 2% for ETFs, he pointed out.
“They don’t really care if the price is high or low, they care about growing their bitcoin treasury so they look more attractive to the proxy buyers,” Marie added. “It’s not so much driven by the macro trend or the sentiment, it’s for different reasons. So it becomes a different kind of mechanism that can push bitcoin forward.”
Bitcoin ETFs, whose collective U.S. launch in January 2024 was one of the most successful ETF debuts in history, still represent the largest holders of bitcoin by entity with more than 1.4 million coins held today, representing about 6.8% of the fixed supply cap of 21 million. Public companies hold about 855,000 coins, or about 4%.
Regulatory relief
The trend reflects the significant regulatory relief the crypto industry broadly is benefiting from under the Trump administration. In March, Trump signed an executive order for a U.S. bitcoin reserve, sending a strong message that the flagship cryptocurrency, which has long been a source of reputation risk among many investors, is here to stay. The last time ETFs outpaced public companies in bitcoin buying was in the third quarter of 2024, before Trump was re-elected.
In the second quarter, GameStop began buying bitcoin, after its board approved it as a treasury reserve asset in March; health-care company KindlyMD merged with Nakamoto, a bitcoin investment company founded by crypto entrepreneur David Bailey; and investor Anthony Pompliano’s ProCap, kicked off its own bitcoin purchasing program and is going public through a special purpose acquisition company, or SPAC.
Strategy, recently rebranded from MicroStrategy, is still the main behemoth in the bitcoin treasury game. The company pioneered the strategy that more than 140 public companies globally are now emulating. It holds about 597,000 BTC, and is followed by the bitcoin miner Mara Holdings, which has almost 50,000 coins.
“It’s going to be very hard to catch Strategy’s scale,” said Ben Werkman, chief investment officer at Swan Bitcoin. “They’re going to be the preferred landing spot for institutional capital because of the deep liquidity around their equity, while these smaller equities are going to be really good risk returns for retail investors and smaller institutions that want more of that upside – that initial growth that comes in kicking off the strategy – because a lot of people missed it with MicroStrategy.”
A long-term case?
Marie suggested that 10 years from now, there probably won’t be so many companies committed to the bitcoin treasury strategy. Firstly, he said, the more that enter the category, the more diluted the activity at each firm becomes. Plus, bitcoin may be so normalized by then that proxy buyers are no longer constrained by rules and mandates around direct exposure to bitcoin.
“You can think about this wave as a bunch of companies that are trying to benefit from this arbitrage,” Marie said.
Werkman pointed out that most investors that are attracted to bitcoin treasury companies today already have a thesis around bitcoin. For them, leveraged bitcoin equities are likely how they try to outperform bitcoin itself, the foundational component of their investments.
“What people really like about these companies, and why they like to get into these smaller companies, is because they can do something that the investors holding spot bitcoin can’t do: go and accumulate more bitcoin on your behalf because they have access to the capital markets and can issue securities,” Werkman said.
There’s also likely to be a fair number of companies that convert their existing treasury holdings to bitcoin without pursuing leverage the way Strategy does, Werkman noted.
“They’ve got that ability to generate more and more value behind their shares, backed by bitcoin, plus whatever the operations of the company are generating. It’s a unique value proposition,” he said.

AeroVironment shares fell 7% Tuesday after the defense contractor said it plans to offer $750 million in common stock and $600 million in convertible senior notes due in 2030 to repay debt.
The drone maker said it would use leftover funding for general purposes such as boosting manufacturing capacity.
AeroVironment shares have soared 85% this year, ballooning its market value to about $13 billion.
Last week, shares of the Arlington, Virginia-based company rallied on strong fourth-quarter results, lifting higher as CNBC’s Jim Cramer called it the “next Palantir of hardware.”

Last month, the company also closed its $4.1 billion acquisition of space-related defense tech company Blue Halo.
Earlier this month, President Donald Trump signed an executive order intended to boost drone production in the U.S. and crack down on unauthorized uses.
The company also has a high short interest level, which may have contributed to some of the recent gains, creating a short squeeze. This phenomenon occurs when a stock price surges, forcing those shorting the stock to purchase shares to cover their positions and prevent losses.
