On the road to electrifying vehicles, cars and small trucks are getting there. Big rigs, however, pose bigger hurdles.

The trouble with electrifying tractor-trailer trucks is that the tractor component needs more power than the current charging infrastructure can handle and the necessary charging time is long.

Major truck manufacturers like Volvo, Freightliner and Tesla are introducing electric tractor-trailer trucks, but that is still a tiny and inefficient market. Big rigs make up just 10% of the vehicles on the road, but they account for nearly 30% of total vehicle carbon emissions.

Now one startup, California-based Range Energy, is focused not on the tractor but the trailer. They are introducing electrified trailers that power and propel themselves so the tractor has less to pull.

“Everything that is built into the tractor is really built to manage the load of the trailer properly, and what we’re saying is, ‘Well, why don’t we do that directly through our Range system by electrifying the trailer in a way that has never been done before?'” said Ali Javidan, CEO of Range Energy.

The Range Energy system incorporates batteries, a motor that powers one of the trailer’s dual axles and what Javidan refers to as a ‘smart kingpin’ to improve the truck’s efficiency.

“When I push this button to activate the system, the trailer follows me,” Javidan said as he demonstrated the system. “It doesn’t matter if I’m an old Peterbilt semi-truck or a brand new Tesla semi or just me pulling on it with the system activated. The trailer’s mission is to make itself feel weightless.”

The electrified trailer can also refrigerate itself as well as power onboard communications and security systems. It does all of that at a fraction of the cost of diesel. 

“If we were to take one of these fleets that runs 3,000 trailers and run it through the range system and essentially incorporate the range system into their fleet, we’re looking at 100 million pounds of CO2 saved per year,” Javidan said. “But even better than that, it equates to about $50 million in fuel savings alone.”

Northern Refrigerated Transportation is piloting the Range trailers in California. The company has previously tried electric tractors but the long charging times were a hurdle, said Ricky Souza, COO at Northern Refrigerated Transportation.

Range Energy’s “trailers seem more of a natural fit because we have to load them, and we load them at night” while the trailers charge, Souza said. “So it’s not more dependent on a driver waiting for it.”

There are, however, some major roadblocks that Northern Refrigerated Transportation must overcome before the company can electrify its entire fleet of more than 300 trucks.

“There’s definitely some infrastructure challenges, like power to the buildings or properties and getting it, and the cost of the unit is more,” Souza said. “That’s part of doing the due diligence to see if you’ll make it back into fuel savings.”

Range Energy has raised $31.5 million so far, and it is backed by R7, UP.Partners, Trousdale Ventures and Yamaha Motor Ventures.

The appeal of Range Energy’s technology is the startup’s different approach to tackling the challenge of electrifying tractor-trailers, said Tyler Engh, R7’s founder and general manager.

“Seventy percent of all freight in the United States is done by trucks, and there’s no one touching a trailer, so if we can electrify the trailer, we could accelerate mass adoption for hybridization or electrification on current fleets that have diesel semis,” Engh said. “The size of what this company could become is exactly what venture capital is set up to do. It could be a humongous return for us.”

As in the EV market for cars, charging infrastructure is still not where it needs to be, but Javidan says trucking companies can leverage the power that’s available at loading docks, as Northern Refrigerated Transportation is doing. Javidan added that Range Energy is able to size the battery pack much closer to what you see in a passenger vehicle than what you see in the large commercial vehicles that are coming out from other big rig companies.

Meta acquiring AI wearable company Limitless

Meta is acquiring artificial intelligence wearable startup Limitless, the companies said Friday.

“We’re excited that Limitless will be joining Meta to help accelerate our work to build AI-enabled wearables,” a Meta spokesperson said in a statement.

Limitless makes a small, AI-powered pendant that can record conversations and generate summaries.

Limitless CEO Dan Siroker revealed the deal on Friday via a corporate blog post but did not disclose the financial terms.

“Meta recently announced a new vision to bring personal superintelligence to everyone and a key part of that vision is building incredible AI-enabled wearables,” Siroker said in the post and an accompanying video. “We share this vision and we’ll be joining Meta to help bring our shared vision to life.”

The world of AI wearables has been slowly growing this year, but no company has landed a standout product.

Meta’s Ray-Ban smartglasses, which have been a surprise hit, have a sprinkling of AI flavor with the inclusion of the company’s AI digital assistant.

There are several wearable devices available that are similar to Limitless.

Friend offers a pendant-style device, Plaud comes in a small card shape or pill that can be clipped on or worn around your neck or on your wrist, and Bee, which is worn on a wristband and was scooped up by Amazon in July.

Amazon also runs AI through its Alexa+ line of Echo Speakers, while Google‘s Pixel 10 phones have the Gemini assistant built in.

Salesforce shares pop 5%, continuing post-earnings rally and leaving stock poised for best week since 2023

Salesforce shares popped 5% on Friday after the company posted better-than-expected third-quarter earnings on Wednesday despite falling short of Wall Street’s revenue estimates.

The stock, which is up 13% over the past five days, is aiming for its best week since 2023.

The company reported adjusted earnings per share of $3.25, topping Wall Street’s estimates of $2.86 per share. Revenue increased 8.6% year over year to $10.26 billion but just missed analyst projections of $10.27 billion.

Although the artificial intelligence boom has pushed several tech companies into record surges, cloud software firms have seen a rocky year as investors wonder whether AI will render the industry obsolete.

Salesforce is hoping to persuade Wall Street that AI will be able to bolster its products rather than replace them.

Investors “somehow think software companies are under arrest from AI, when the opposite is true,” Salesforce CEO Marc Benioff told CNBC’s Jim Cramer on Thursday.

During the third quarter, the company acquired startups Regrello and Waii, which uses AI to generate code with natural language instructions.

Despite Salesforce’s shares being down 21% year to date, compared with the Nasdaq’s 22% gain, analysts are more optimistic for 2026.

“CRM [Salesforce] continues to be levered to digital transformation, and we expect the company to grow at a solid rate going forward,” Mizuho analysts wrote. “At the same time, we believe CRM will remain fiscally disciplined and that it can continue to drive higher operating and FCF margins.”

Analysts highlighted Salesforce’s AI platform Agentforce, which builds agents that automate business tasks and streamline workflow.

Despite initial investor skepticism over the platform, Cantor analysts were encouraged by its strong adoption in the customer service space.

“We think CRM is starting to formalize and mature the strategy, which should make it easier for customers to understand, and therefore adopt, Agentforce,” the Cantor analysts wrote.

Annual recurring revenue of Agentforce jumped 330% year over year to $540 million.

“Why everyone is so excited about Agentforce is because this is what AI was meant to be,” Benioff said. “It brings together humans and data and AI and apps, and delivers an incredible experience for companies.”
