Shares in CoreWeave Inc are sinking this morning after the company revealed its third-quarter 2025 results yesterday. While the New Jersey-based AI infrastructure firm more than doubled its revenue from the same quarter a year earlier, it also revised down its full fiscal 2025 forecast, sending its stock price tumbling. Here’s what you need to know. What’s happened? Yesterday, AI infrastructure company CoreWeave announced financial results for its Q3 2025, which ended on September 30. There was some good news for the quarter, including revenue of nearly $1.4 billion (up 134% year over year) and a revenue backlog of $55.6 billion (up 271% YoY). Revenu…

I have what I consider a healthy skepticism toward authority. I’ve always considered leaders—despite what titles they hold—as fallible people who don’t necessarily deserve blind adulation or deference. That skepticism has made it hard for me to adopt the “company man persona,” which might explain how little of the proverbial corporate ladder I’ve climbed. And rather than take responsibility for that, I’m going to “blame” my dad: The instinct to question rather than comply, to think critically instead of playing yes-man, came from him. We never had a formal conversation about it. I just watched how he moved through the world—confident, grounded, with little to prove—a…

Hello and welcome to Modern CEO! I’m Stephanie Mehta, CEO and chief content officer of Mansueto Ventures. Each week this newsletter explores inclusive approaches to leadership drawn from conversations with executives and entrepreneurs, and from the pages of Inc. and Fast Company. If you received this newsletter from a friend, you can sign up to get it yourself every Monday morning. Leaders juggle a lot of demands and priorities. However, most CEOs tell me they’re highly attentive to company culture, change management, and workforce transformation in the age of AI—all areas that their chief human resources officers (CHROs) or chief people officers (CPOs) are tackling, …

For professionals looking to moodboard, but sick of juggling Instagram lists and Pinterest boards, Cosmos arrived in 2023 to woo millions of users in an otherwise crowded market. With a pared-back design, and an algorithm trained on a carefully seeded list of creatives, it topped the Design category in the App Store, and the company reports it’s now used by creative teams at companies including Nike, Apple, and Amazon, who snag over 10 million pieces of content a month from across the internet for their collections. This growth has been enough to raise a $15 million Series A from Matrix Partners, GV, Accel, and Squarespace CEO Anthony Casalena, as the company con…

Shares of Costco (COST) fell over 7% in midday trading on Friday after the wholesale retailer reported mixed second-quarter earnings results, missing profit estimates but beating on revenue, as the company braces for the impact of tariffs and inflation on consumer spending. “The tariffs are very fluid right now, so it’s hard to give any predictions about what we can do, but our people are well equipped to deal with anything coming our way and we have great partnerships with our suppliers,” CEO Ron Vachris said during the company’s earnings call. “Our people are nimble and ready to go.” Costco’s Q2 revenue came in at $63.72 billion, slightly beating analyst estimat…

The legendary $4.99 rotisserie chickens from Costco are under fire this week as a proposed class action lawsuit claims the big box retailer has been misleading customers. Two California shoppers noticed something that might seem obvious in retrospect: To sell an entire, slow-roasted chicken in a plastic bag, Costco added two preservatives. Problem is, the Issaquah, Washington-based company had promised on the packaging, in-store displays, and online that the chicken contained “no preservatives.” The lawsuit filed last week with the Southern District claims that Costco’s promise that its rotisserie chickens contain no preservatives signals to “reasonable consumers“…

Costco is famously adored by its fans, and its leadership wants the discount big-box chain to remain beloved. Costco co-founder and former CEO James Sinegal so fervently believes in keeping customers happy that he’s driven to profanity to express the strength of his feelings. “You can’t say ‘People are our most important product,’ and hang signs all over the place that say ‘People are our most important product,’ and then treat them like shit…. Your customers or your suppliers are going to see that you don’t really mean it,” he recently told an interviewer. Which is why a recent policy change by the retailer is so fascinating. Starting this month, Costco b…

Branded is a weekly column devoted to the intersection of marketing, business, design, and culture. Costco has been on a good run lately. The beloved big-box club chain has been winning new fans for its no-nonsense stand on continuing its DEI policies, with comparable store sales up 6.8% in its most recent quarter. But as Costco shoppers know, its in-house Kirkland Signature brand, which includes everything from underwear to frozen pizza, has long been the discount club’s not-so-secret weapon. Kirkland marks its 30th anniversary this year, and in what’s shaping up to be a challenging economy for consumers across the board, it’s poised to become more important than eve…

Costco’s latest promotional offering just dropped, but members aren’t rushing to claim it. At select warehouse club locations, members can now take home complimentary 3-pound bags of Gala apples. The shopping warehouse’s unique business model, wherein membership fees contribute largely to its revenue, means that it focuses on plugging its membership more than advertising specific products. Costco puts significant effort into encouraging people to join, or upgrade and renew, existing memberships. In the past, Costco has offered enticing items like tote bags to coax customers into automatic membership renewals, but the promotional bag of apples is not as appealing…

You’re three days into a work trip in a foreign city, running late for a meeting, and you yank the zipper on your carry-on one last time to force it closed. It catches. You pull harder. The slider pops off the track, and suddenly a piece of luggage that cost you several hundred dollars is, for all practical purposes, an open box with wheels. You find a hotel concierge who points you to a cobbler. You buy a roll of duct tape. You miss your meeting. The zipper is the single most common failure point on a rolling suitcase. It’s the part under the most stress every time a traveler overpacks, sits on the suitcase’s lid to close it, or hands the bag to a gate agent to be to…

We know that having friends at work is good for your performance and happiness. But could ChatGPT replace your happy hour bestie? According to a new study from KPMG that surveyed more than 1,000 professionals, almost all (99%) would be open to the idea of an AI chatbot assuming the role of close friend or trusted companion at work. That same study teases out a separate, also compelling thread: 45% of workers reported feelings of loneliness at work. That’s a huge jump, up nearly double from last year. On top of that, the survey found that friendship seems to be a big priority for most workers—even over money. More than half (57%) of those surveyed said they wo…

In 2008, the American dream of homeownership morphed into a nightmare that tanked the global economy. The culprit? A toxic mix of bad mortgages and casino mentality. Today, another financial time bomb is ticking—and this one is fueled by rising seas, wildfires, and a lethal dose of denial. Climate change is quietly corroding the foundations of the U.S. housing market. From Florida’s hurricane-battered coasts to California’s fire-razed suburbs, a crisis is brewing that could make the subprime mortgage collapse look like a warm-up act. The crisis will be triggered by home insurance. To get a mortgage, you need homeowner’s insurance. But in climate-vulnerab…

In a social media landscape dominated by obnoxious ads, algorithms, and AI, Letterboxd has stood firm as a cult favorite. The app, which acts as a digital diary for users to log and leave reviews of any movie they watch, has been described by a Letterboxd spokesperson as “less a social media platform, more a community.” It’s resisted adding the infinite scroll feature that now seems omnipresent online, instead letting users curate their own feeds of friends and popular reviewers. But news that a controlling stake in Letterboxd could be going up for sale has users worried that their online safe haven could go the way of other resold apps like X. Canadian holdin…

Smartphones have been the greatest drivers of creative democratization over the past 15 years, giving people a powerful voice and platform. Recent advancements in the “brains” behind these devices are almost limitless, from their software and processing power to their AI capabilities. But what about their bodies? For years, the smartphone’s physical form has remained a familiar slab of glass and ceramic. This form factor, once revolutionary, is now becoming a physical constraint on creativity. Over time, smartphone design has created a paradox. The very tool meant to capture our memories can prevent us from truly living in the moment. While the intention was to connec…

Catherine Bashiama runs her fingers along the branches of the coffee tree she’s raised from a seedling, searching anxiously for its first fruit buds since she planted it three years ago. When she grasps the small cherries, Bashiama beams. The farmer had never grown coffee in her village in western South Sudan, but now hopes a rare, climate-resistant species will help pull her family from poverty. “I want to send my children to school so they can be the future generation,” said Bashiama, a mother of 12. Discovered more than a century ago in South Sudan, excelsa coffee is exciting cash-strapped locals and drawing interest from the international community amid a global cof…
