Canadian chip company Untether AI winding down operations
Promising Canadian chip startup Untether AI Corp. is winding down after failing to raise money earlier this year, and its engineering employees will be transferred to American company Advanced Micro Devices AMD-T.
The arrangement is known as an 'acquihire,' in which one company strikes a deal with another to gain access to talent instead of products or services.
Toronto-based Untether designed computer chips for artificial intelligence applications such as autonomous vehicles, robots and drones, and said its products were far more energy efficient than others on the market.
But the company pivoted too late to the hardware market for powering generative AI applications, such as OpenAI's ChatGPT, according to two sources familiar with the matter, and struggled to compete against the dominance of Nvidia Corp. NVDA-T in the chip market. Economic uncertainty owing to U.S. President Donald Trump's tariff agenda contributed to difficulties raising new funds from investors this year, one of the sources said.
The Globe and Mail is not identifying the sources because they are not authorized to discuss the matter.
Untether said in a statement on its website Thursday that it had entered into a 'strategic agreement' with chipmaker AMD, which is based in California. 'While today marks the end of Untether AI's journey, we are proud of the pioneering research that underpinned our work,' the statement read. The company added it will no longer supply or support its hardware and software products.
AMD said in a statement to trade publication CRN that it is acquiring 'a talented team of AI hardware and software engineers' from Untether.
One source said the value of the deal would likely be less than US$100-million depending on how many employees agree to join AMD. The source added that Meta Platforms Inc., which is working on custom chips for AI applications, was also in talks with Untether.
It is not clear what will happen to Untether's intellectual property, which is not part of the transaction, but the source said it could be sold separately.
Neither Untether nor AMD immediately replied to a request for comment.
From 2024: Toronto's Untether straps in for growth selling AI chips - but can it avoid getting crushed by Nvidia?
Chris Walker, Untether's chief executive, left the company in May, according to his LinkedIn profile. He did not reply to The Globe and Mail.
Untether was founded in 2018 and received funding from Intel Capital, Radical Ventures, GM Ventures and Canada Pension Plan Investment Board. The company has raised around $150-million. That means given the potential value of the deal, investors are likely not recouping the total amount they invested. However, losses will depend on when investors first put money into Untether.
The company's products were built on the research of co-founder and former University of Toronto professor Martin Snelgrove, who pioneered a different computer chip architecture.
The dominant approach to chip-making has followed a design laid out by mathematician and physicist John von Neumann in 1945, but that design wastes a lot of energy shuttling data around. Untether cut the distance data must travel by placing memory and processing units side-by-side on the hardware.
Untether pursued the self-driving vehicle market and other systems that use a form of AI know as computer vision, which involves detecting and interpreting objects in videos and images. But the AI world changed with the release of ChatGPT in late 2022, as companies became obsessed with generative AI and chatbots. Nvidia became the most valuable publicly traded company in the world as large tech firms scrambled to purchase chips to install inside data centres for training AI models.
Untether aimed to compete with Nvidia in the much larger market for powering AI inference, the term for using an AI model after it is built, such as asking a question of ChatGPT.
Independent tests gave Untether's products high marks. MLCommons, an industry and academic consortium that benchmarks AI systems, found last year that one of Untether's chips was six times more energy efficient than competing products, and with lower latency, in one testing category.
But Untether's push into the market for chips housed in data centres for generative AI may have come too late, especially given Nvidia's scale and reputation. The California-based company is worth close to US$3.5-trillion.

Alberta gives U.S. liquor imports thumbs-up
Stores in Alberta can now sell newer American liquor products after a provincial agency ended a three-month pause ignited by a tariff dispute between Canada and the U.S. Article content The directive came from the province as Canada shifts its approach from retaliating to negotiating with its southern neighbour on economic policies. Article content Article content Minister of Service Alberta and Red Tape Reduction Dale Nally, in a statement on Friday night, said the government's decision heralds a 'renewed commitment to open and fair trade with our largest partner.' Article content Article content 'The decision sets the stage for more constructive negotiations ahead of a Canada-United States-Mexico Agreement renewal, potentially leading to increased trade opportunities and economic growth for Alberta,' Nally added. Article content Article content The decision concerns liquor products registered with the Alberta Gaming, Liquor and Cannabis agency (AGLC) and declared to the Canada Border Services Agency. A 25 per cent surtax will continue to be levied on those items shipped from the U.S. after March 4 and will be collected by the provincial agency. Article content Article content Ravinder Singh, a manager at ACE Liquor Discounters Edmonton Trail, said the decision likely won't affect the store's sales, as the shop's inventory still holds enough stock of older American products. Article content The move to ban the sale of American liquor was made in early March amid escalating trade tensions. Article content Article content 'If the Americans aren't going to buy products from our Canadian companies, we have to,' Premier Danielle Smith said at the time. Article content 'That means we should be buying more Canadian beer, more Canadian spirits and more Canadian wine. And so that's the reality of what we're facing.' Article content The ban was lifted March 18, but the sales were confined to AGLC's central locations. Article content Singh said the demand for American products dropped after March owing to a wave of patriotism across the country. Whereas the store sold them daily, the products are now being bought twice or thrice a week, even three months after the pause.

If I Could Only Buy and Hold a Single Stock, This Would Be It.
Let's make this clear from the start: I would never recommend owning just one stock for the long haul. A proper nest egg needs some variety, either in a carefully assembled basket of diverse stocks or focused on a broad market-tracking exchange-traded fund (ETF). For the sake of argument, however, I could imagine buying some Berkshire Hathaway (NYSE: BRK.A)(NYSE: BRK.B) stock and just letting it roll. The usual suspects aren't diverse enough for this challenge I know, I know. You wanted me to double down on Amazon (NASDAQ: AMZN), whose stock has absolutely crushed the general market in the long run. Or I could have picked Netflix (NASDAQ: NFLX), the media-streaming pioneer that's created most of my wealth so far and that might join the trillion-dollar market cap club in a few years. Perhaps you expected Nvidia (NASDAQ: NVDA), with its unmatched five-year returns and huge long-term future in the artificial intelligence (AI) industry. These stocks sure tick a few of the right boxes, but none of them are as naturally diversified as Berkshire Hathaway. That's really what I'm looking for in a "single stock for all ages." Why my biggest winners don't make the cut I own all three of the suggested Berkshire alternatives above, by the way. Netflix Netflix was an early name in my portfolio, inspired by fellow Fool Rick Munarriz's in-depth analysis of the company in the mid-2000s. When Netflix went through the Qwikster-branded separation of DVD and streaming services, I doubled down on my investment at a fantastic price. That particular Netflix stake has gained 10,350% in less than 14 years. But that's just my favorite play on the future of digital media services. I would never dare to make Netflix my only holding, just in case somebody builds a better media-streaming mousetrap. Amazon I wish I had pounced on Amazon much earlier, like Motley Fool co-founders Tom and David Gardner did. But I dragged my feet, and watched the online bookstore become an e-commerce buffet with a highly profitable side of cloud computing services. My oldest Amazon investment is only up by 430% since January 2017. Still, Amazon only operates in a couple of business sectors. The company (and stock) could be vulnerable to a sudden sea change in cloud computing, possibly led by Microsoft 's (NASDAQ: MSFT) Windows Azure. And how well would Amazon's dominant e-commerce business perform if global rivals such as Alibaba (NYSE: BABA) or MercadoLibre (NASDAQ: MELI) found some traction in the American market? Amazon is not a one-trick pony, but the company should pick up a few more skills before entering this single-stock discussion. Nvidia I'm especially worried about Nvidia's long-term tenacity. The early leader in AI accelerator hardware could very well run into a superior alternative in the next few years. The risk only grows larger if you stretch the timeline out over decades. Rivals like Advanced Micro Devices (NASDAQ: AMD) and Intel (NASDAQ: INTC) control tiny slices of the AI chip opportunity so far, but that could change. The next market-defining AI winner could be some upstart I haven't heard of yet. Moreover, leading cloud computing experts such as Microsoft and Amazon already design AI accelerators of their own, hoping to meet their exact needs at a lower cost. Nvidia's big growth spurt might have a few years left in it. I'm just not convinced that the stock will continue to rise after that. My largest Nvidia purchase has posted a 780% gain since June 2022, but I cashed in on those paper gains and sold most of my Nvidia shares earlier this year. This pony needs to learn a few more tricks, too. Berkshire is the Swiss Army knife of stocks So diversity sets Berkshire apart from the biggest success stories of this era. Sure, Warren Buffett's stock-picking and wealth management expertise deserves tons of respect. But he is also known as a great mentor, and many of Berkshire's top-performing picks in recent years were added by Buffett's lieutenants. I expect the company to continue doing well when the Oracle of Omaha retires at the end of 2025. The stock is kind of like a carefully curated ETF. Berkshire Hathaway owns and operates 68 distinct companies these days. The names range from GEICO car insurance and Duracell batteries to Business Wire information services and the Burlington Northern Santa Fe railroad. Berkshire dabbles in e-commerce (Oriental Trading Company) and clothing (Fruit of the Loom), not to mention home construction (Clayton Homes) and fast food (Dairy Queen). This business list is almost as diverse as the S&P 500 (SNPINDEX: ^GSPC) market index. And that's just Berkshire's in-house brands. The company also owns stock in about 40 public companies. The largest investments include a $60.7 billion stake in Apple (NASDAQ: AAPL), a $45.1 billion position in American Express (NYSE: AXP), and a $28.5 billion holding of Coca-Cola (NYSE: KO). That's consumer electronics, financial services, and beverage distribution. Apple's gigantic presence may look risky, but the danger looks smaller when you also consider Berkshire's epic collection of fully owned businesses. Do you see a theme here? I do, but it's not a single industry. Berkshire is all about diversity, shielding the company and its investors against the temporary ups and downs in any one particular industry. Full disclosure: I don't own Berkshire (yet) I don't actually own any Berkshire Hathaway stock yet. I get my portfolio diversification kicks in other ways, with several dozen hand-picked stocks and a couple of broad index funds serving this purpose. That's arguably a mistake, since Berkshire's stock tends to outperform the S&P 500 in the long run, and I can't compete with the Buffett team's stock-picking skill. So if you're starting a new portfolio today, or just looking for an alternative to the common S&P 500 index funds, you should give Berkshire Hathaway a serious look. It's definitely a safer long-term bet than Nvidia, Netflix, or even Amazon. Should you invest $1,000 in Berkshire Hathaway right now?
