Corporate America can't afford to ignore Gen Z

This is the year Gen Z takes over, and fusty companies that want to sell them stuff have to crack the kids' code.

Ziad Ahmed sees what a challenge it is every time he makes a presentation, as he did recently to some American Express Co. marketing executives. It was his "Gen Z Crash Course/Make a Meme Workshop," and they drew blanks watching slides about the dialect spoken by the young.

Esketit? O.T.P.?

One guy took a stab. "Old Tired Person?" Ah, no. That stands for "one true pairing," to describe a perfectly matched couple.

Esketit, coined by the Gen Z rapper Lil Pump, means "Let's get it."

It's a learning curve.

"People are just starting to catch up," said Ahmed, the 20-year-old chief executive of JUV Consulting, which sells expertise in his cohort, who are, according to the firm's website, "sought after as customers and misunderstood as people."

"We are the social-media natives," as Ahmed put it. They are distinct from the millennials before them — who were "digitally native" only — and they don't shop the way their parents do. One estimate is that they already have direct spending power of as much as $143 billion. And most of them are still in school.

Whatever the actual amount of money in the possible Gen Z spending pot, companies don't want to — and can't afford to — blow it as many did with millennials. A common assumption was that those young people now in their 20s and 30s weren't interested in the American tradition of consumption. Maybe they weren't, but only because they were broke, having come of age during the 2008 financial crisis and following recession.

Automakers, for one, took the bait, rolling out smaller cars they figured that generation would go for, models being killed off now that more millennials are flush and hankering for gas-guzzling SUVs.

Levi Strauss & Co. got it wrong too, which CEO Chip Bergh said hit home when his own millennial sons wouldn't wear the brand. Kraft Heinz Co.'s jaw-dropping $15.4 billion write-down on stale brands last month helped frame just how wide the millennial miss was for some leading names.

People in generational cohorts are never as uniform as marketers would like. Still, to hear researchers and Gen Zers themselves tell it, this one will put a new spin on consumerism, making things difficult for the big, established chains.

They don't much use e-mail or Facebook; think Instagram and YouTube instead. They're into thrift-shopping and internet influencers. They sure don't watch ads on TV, whatever that is.

They prefer word-of-mouth (preferably through meme or post or video) when it comes to enlightenment about what to buy, said Adam Grant, 33, the CEO of the marketing agency Campus Commandos. "What's better than learning about a product or service than your friend?"

A survey of 11,000 U.S. adults by Bloomberg News and Morning Consult shows the generation is more willing than its predecessor to put its money where its values are.

"If they're paying money to corporations, they have to align with what they believe in," said Corey Seemiller, an associate professor at Wright State University who became a lecturer on Gen Z after a student asked to skip a community-service requirement because she was running her own nonprofit.

Gen Z is expected to accelerate the shop-online trend, with an emphasis on subscription and customization, such as those from algorithm-driven businesses like the personal styling company StitchFix.

Companies are trying. Kellogg Co. hired what it calls "inspiring Gen Z leaders" ages 12 to 17 to design its newest Kashi cereal. McCormick & Co. has a new marketing program called Imagine that, the spice maker says, "directly links our food, flavor and products with our sustainability efforts." Ulta Beauty Inc. sells a vegan and cruelty-free line aimed at "Gen Z beauty enthusiasts."

Another advertising tack: targeting Gen Z with the sounds — like whispers or slurps — that can trigger an autonomous sensory meridian response, also known as a brain orgasm. ASMR videos are huge on YouTube; they can be relaxing and may help you sleep after too many hours of stimulating blue light from your always-on screen.
