Two months after coming out of stealth with a $150 million fundraise, Boston-based Teradar is showing off its first flagship terahertz sensor at Consumer Electronics Show 2026 this week. The company is positioning the sensor, called Summit, as the first long-range, high-resolution sensor of its kind “designed for high performance in any type of weather, filling a critical gap left by legacy radar and lidar sensors.”

The sensor will start shipping until 2028 if Teradar can lock down contracts with automakers. If that happens, the company expects the Summit will help enable those companies to add partial, or even full, autonomy features to their vehicles.

Teradar’s whole approach is about leveraging the relatively-unused terahertz band of the electromagnetic spectrum between microwaves and infrared. And it’s a solid-state sensor, meaning there are no moving parts. All this is meant to give Teradar’s sensor the best qualities of lidar and radar sensors, with few of the drawbacks.

It’s a potentially attractive proposition for automakers who might wince at the cost of lidars or the limitations of radars. Teradar says it’s already working to prove its tech with five top automakers from the U.S. and Europe, and three Tier 1 suppliers.

Teradar’s impending entry into the market comes at a pivotal moment for automotive sensor suppliers. Leading U.S. lidar company Luminar just filed for bankruptcy protection in December after contracts with Volvo and Mercedes-Benz fell apart, as the automakers backed away from the tech.

Those deals also crumbled partly because of low-cost competition from China, according to Luminar. Lidar adoption has been strong in China’s auto market and shows little sign of slowing up. In October, Chinese lidar company Hesai said it had built more than 1 million lidar sensors in 2025.

Other U.S. companies in the space, like Ouster (acquired and merged with rival Velodyne after a wave of consolidation) have diversified into potential markets like robotics and smart infrastructure.

Teradar is looking beyond automotive, too, and that vision was reflected in its recent raise. The $150 million Series B included funding from Lockheed Martin’s venture arm, and VXI Capital, a new defense-focused fund led by the former CTO of the U.S. military’s Defense Innovation Unit.

Lidar isn’t completely dead in the auto industry, however. Rivian in December said it would integrate a roof-mounted lidar sensor (from an unnamed supplier) in its upcoming R2 SUV, signaling that there is still an appetite for using advanced sensor technology to bring autonomy to passenger vehicles, especially if it’s affordable.

Teradar CEO Matt Carey told TechCrunch in November that he believes his terahertz sensor can meet all those marks, and sounded eager to pounce on the opportunity.

“Our main job is to make sure our sensor gets on all automobiles, and whatever the best way to do that is, that’s what we’re going to pursue,” he said.

Effective Jan. 1, brothers Angelo and Edoardo Zegna are tasked with leading the Zegna brand forward as CEOs while their father Gildo has assumed the role of executive chairman.

Effective Jan. 1, Gildo Zegna, undoubtedly instrumental in shaping the Ermenegildo Zegna Group into the international, publicly listed company it is today and driving it into the 21st century, passed the baton to his two sons.

Although not entirely unexpected, this was a forward-looking choice that stood out in an industry where the generational handover is often not a top priority. However, it is one that must be planned “bravely, when you are in good health, and have the right energy,” said Gildo Zegna at the end of November, when he revealed he would become executive chairman of the group, which in addition to the Zegna brand also comprises Thom Browne and Tom Ford Fashion, in addition to the textile segment.

Zegna, who has led the group since 2006 and was previously group chairman and chief executive officer, turned 70 on Sept. 30 and said that he had started working on the handover plan two years ago, and more actively over the past year.

Chief financial officer Gianluca Tagliabue took on the role of CEO of the group on Jan. 1.

Gildo Zegna’s sons Angelo and Edoardo, members of the family’s fourth generation, were named co-CEOs of the Zegna brand, reporting to Tagliabue.

What will the group look like under their leadership? According to their father, they are “complementary and naturally balance each other out. They don’t compete with one another. Edoardo is more extroverted and very rational, Angelo is more execution-driven. They will play for the team with no ego. They have a clear vision and they will continue the family legacy, having demonstrated their business leadership over the past years. Together, they will not only carry forward the brand’s timeless heritage, but strengthen it further.”

It is true their expertise and different skills were developed over the years, also outside the family company.

Edoardo Zegna, 39, has lived in Washington, New York and San Francisco and is currently based in London. He has worked at Gap Inc. with the creative concept team in New York from 2009 to 2011 and after that, from 2011 to 2014, he was head of product at the American fashion brand Everlane and one of the first employees of that company.

He was appointed head of content and innovation and omnichannel at the Ermenegildo Zegna Group in 2014, later becoming chief marketing and digital officer of Zegna as well as group chief sustainability officer. He greatly contributed to Zegna’s One Brand strategy; the entirely traceable Oasi Cashmere collections; the Zegna X digital customization tool aimed at raising the bar of luxury service, and the exclusive Villa Zegna experiences. As co-CEO of Zegna, he will lead all aspects of brand strategy, from brand image to marketing, and, together with Zegna’s artistic director Alessandro Sartori, design matters, including store design.

Angelo Zegna, 37, held the role of CEO of Zegna’s Europe, Middle East and Africa region and global event strategy director and global client strategy director, and as co-CEO he will oversee product development, merchandising and commercial strategy, driving performance across markets and channels.

Earlier in his career he oversaw Zegna’s retail business in the U.S., spearheading transformative programs focused on client experience and commercial excellence, such as an app to offer personalized styling remotely.

Before that he contributed to strategic and operational projects at Luxottica in São Paulo and New York and worked as a consultant with Bain & Company in Mumbai, where he focused on strategy and performance improvement across emerging markets.

As for Tagliabue, before talking on his CFO role, he was chief operating officer, overseeing the supply chain, a key position for Zegna. He’s now tasked with further integrating Thom Browne and Tom Ford Fashion into the group.

In his new role as executive chairman, Gildo Zegna will continue to oversee the group’s textile platform, the foundations of the company.

As well as the group’s textile division, he will oversee the group general counsel’s office (including internal audit), and the external relations department, which encompasses sustainability, investor relations and corporate communications.

The executive has been instrumental in shaping the Zegna group into an international powerhouse with 2024 sales of 1.94 billion euros; selecting Sartori, who has been successfully evolving Zegna’s style; taking control of the Thom Browne brand in 2018; inking a long-term agreement with the Estée Lauder Cos. Inc. in 2023 for the production and distribution of the Tom Ford Fashion label, and publicly listing the group on the New York Stock Exchange in December 2021.

Lowest doses of Wegovy in oral form will start at $149 a month for US users until April

Novo Nordisk is launching a weight-loss pill price war as it seeks to keep pace with arch-rival Eli Lilly in the market for GLP-1 drugs.

The Danish drugmaker announced on Monday that patients could purchase the lowest 1.5mg and 4mg doses of its Wegovy pill for $149 a month in the US until April, when the 4mg dose will rise to $199 a month. Patients with insurance can pay as little as $25 a month for the lowest doses.

Higher doses of the drug at 9mg and 25mg are priced at $299 for a month-long supply.

Shares in the Copenhagen-listed company rose more than 2 per cent on Monday following the announcement, but have fallen 45 per cent over the past 12 months.

The Wegovy pill costs significantly less than Novo’s injectable version of the drug and Lilly’s own injectable, Zepbound, which dominate the market. Both drugs cost more than $1,000 a month but the price will be cut to about $350 when TrumpRx, the medicine purchasing website proposed by US President Donald Trump, launches later this year.

The pricing announcement comes weeks after the oral version of Wegovy was approved by the US Food and Drug Administration, marking the first regulatory nod for a weight-loss treatment in pill form.

The lower prices signal the start of a race to attract more patients who are overweight or obese. The pill resulted in an average weight loss of about 17 per cent of body weight after 64 weeks, according to trial results announced by Novo.

The pill must be taken daily on an empty stomach. Users have to wait at least 30 minutes before eating, drinking or taking other oral medications in order to give the pill time to absorb, according to the company’s instructions.

Lilly’s weight-loss pill, orforglipron, is expected to be approved by the US regulator this year. The White House said last year that it had reached a deal with Lilly for orforglipron to cost $346 a month when purchased through TrumpRx.

Orforglipron has had mixed fortunes in clinical trials. It disappointed in a trial of people without diabetes, delivering an average weight loss of 12.4 per cent of body weight, which was at the lower end of analysts’ expectations.

However, the drug met the company’s targets in achieving 10.5 per cent weight reduction in overweight people with diabetes.
