Estella Struck founded Viviene New York, a marketing agency that promotes sustainable businesses. She's also a rising star of influencer management.

The 23-year-old told BI that she's "not a perfume maximalist" — but there are two scents she loves.

"I really like Aesop. I think they have an amazing line of fragrances, and they're unisex," she said.

She's purchased the Tacit scent for herself, which costs $160 or $220 depending on the bottle you buy, and the $200 Karst scent for her boyfriend.

"I'll use his Aesop scent depending on my mood," she added.

Struck told BI that she loves the scent of Gucci Bloom but doesn't find it to be the most sustainable and skin-friendly option on the market.

It's also priced pretty high, between $110 and $128 each for full-sized bottles.

So, the marketing professional turned to Dossier, a brand known for selling clean, inexpensive fragrances inspired by designer products.

Struck said the brand's Floral Honeysuckle perfume smells exactly like Gucci's, and the bottle costs $39.

Abby Carlos has spent the past two years working as a media strategist for Warner Bros. Discovery.

So far, she's worn the same perfume each day on the job: Victoria's Secret Bombshell.

She prefers the brand's original scent, which is sold as a body mist, lotion, and perfume (though the latter is sold out).

Other variations of the fragrance — including Bombshell Intense — are still available on the Victoria's Secret website for upward of $60.

Carlos told BI she likes to wear a limited-edition Carolina Herrera scent called Good Girl Fantastic Pink for nights out.

"It's packaged in a sparkly pink bottle, and I get so many compliments on that one," she said.

She also previously enjoyed the brand's Very Good Girl scent, packaged in a red, heel-shaped bottle. But over time, she thinks it's become a bit overrated.

"It felt like everyone started wearing it," she said of the perfume. "I was like, 'Oh my God. Now I've got to find a new scent.'"

Bottles of the latter fragrance — and others in Carolina Herrera's Good Girl line — range in price between $94 and $192 per bottle. The brand no longer sells the Fantastic Pink line, but it can be purchased on fragrance websites and Amazon.

Sabrina Guler, 31, is an author and entrepreneur who cofounded the real-estate investment company Techvestor, which landed her on BI's rising stars of real estate list.

"I love Viktor & Rolf's Tiger Lily," she said. "That's been my go-to, and I always get complimented on it."

She describes the scent as floral, feminine, and "very sexy."

"I'm someone who wears fragrance when I want to enhance my self-love," she said. "If I want to feel better about myself, if my mood is kind of off, or if I just want to feel more connected to me, I'll add a little bit of perfume."

Asia Gousse found herself on BI's list of rising stars in influencer talent management thanks to her work with Slash Management. She works with an all-female client roster that she discovered on TikTok.

Even when her job is busy, the 28-year-old makes time for a thorough fragrance routine.

Gousse always begins by applying unscented body oil to help her perfume last longer. She then uses the $14.99 Being Frenshe body spray in Cashmere Vanilla as a base layer for a rotating perfume.

Sometimes, she sprays Valentino's Born in Roma Intense, which costs between $110 and $140. On other days, she chooses Maison Margiela's Replica Afternoon Delight ($35 to $165) or Viktor & Rolf's Flower Bomb Ruby Orchid ($38 to $225).

Finally, she uses a niche fragrance from Idult Paris called Tiholta, which she says is the "truest vanilla" scent she can find. It costs 180 euros, or about $187.

"I want to always walk around smelling like a vanilla cupcake. It's my pride and joy," she said.

Anna Molinari is a 26-year-old content creator and sustainable fashion designer. She's also a newly cemented fragrance fan.

"I never used to be a fragrance person, but now I've been learning about them as I receive them in PR packages," she told BI. "My favorite is the YSL Black Opium Over Red."

In addition to the YSL scent, which costs between $35 and $160 per bottle, Molinari enjoys the Mugler Alien scent, which retails for around $150 per bottle.

"My issue with perfumes is that, to me, they can smell like old ladies," she said. "So what I like about the YSL cherry scent specifically is that it does smell very fruity. Same thing with Mugler Alien. I can wear them every day."

Uber CEO Dara Khosrowshahi spent time picking up shifts as an Uber Eats delivery driver on an e-bike and an Uber driver for a spell in 2022.

He bought a secondhand Tesla Model Y to ferry riders around San Francisco and made deliveries using the alias "Dave K." He did this when the company was struggling with recruitment.

Khosrowshahi told The Wall Street Journal in April 2023 he was surprised how passengers would often discuss personal or sensitive information as if he wasn't there. While making deliveries on an e-bike, he encountered "tip-baiting," where customers offer a big tip but reduce it on delivery.

The experience showed him that the company culture was focused on customers and not drivers. "We didn't take pride in the driver product because very few of us drove," he said.

Khosrowshahi shared his findings at a companywide all-hands titled "Why we suck."

He said the meeting wasn't "pleasant" but that it led to a shift, telling the Journal, "We started celebrating employees going out there delivering, employees driving. It is a point of pride for employees now — when they drive they get a little badge on their corporate profile."

Laxman Narasimhan said he spent six months immersing himself in all aspects of the company, including training as a barista, before taking over from Howard Schultz as Starbucks CEO.

When he took over the job, Narasimhan said he planned to continue working monthly half-day shifts.

In his first annual letter to staff in March 2023, Narasimhan said he wanted the practice to help "keep us close to the culture and our customers, as well as to our challenges and opportunities."

"I expect each member of the leadership team to also ensure our support centers stay connected and engaged in the realities of our stores for discussion and improvement," he added.

During his barista shifts, he burned his hand on a sandwich and had an egg bite explode in front of a customer. This prompted him to make several key changes, including sending more breakfast sandwiches to stores to avoid shortages, making packaging for egg bites easier to open, and sending fewer corporate emails to stores.

In 2022, Brian Chesky said he spent six months living full-time as a guest in a series of Airbnbs to promote remote work.

The Airbnb CEO last year told Fortune the experience varied greatly from place to place: some hosts would request he pay "giant" cleaning fees, and others handed him a chore list.

"I started noticing variability," he said. "I'd ask them, 'Why are you doing all of this?'"

After Chesky's Airbnb stays, he launched 50 features, Fortune reported, including Airbnb Rooms — individual rooms to rent instead of whole homes.

To promote these listings, Chesky put a guest room in his own San Francisco home on the app for free, from 2022 to March 2023. While the listing is no longer accepting guests, some of those who did get the opportunity in 2023 left glowing reviews.

"I feel like I'm reviewing Steve Jobs' personal iPhone," one guest wrote in a review praising Chesky for facilitating "a smooth check-in."

DoorDash CEO Tony Xu makes monthly deliveries as part of WeDash, a program begun in 2015 that requires salaried employees to carry out several deliveries a year.

Xu told "The Rideshare Guy" podcast last year that it had sparked ideas for improvement. He said the company had a Slack channel dedicated to issues people identify from WeDash, such as app bugs or getting the wait times for deliveries wrong.

Xu also said it helped him and his employees solve problems, in an interview on Stanford Graduate School of Business's "View From The Top" podcast in 2021.

"If you're at the surface level, you're never going to actually realize what the problems are," he said.

On the podcast, he also shared that he does customer service for the company daily, which he said can sometimes shed more light on areas for improvement than data.

"Sometimes, it's really hard just looking at the data to get to the digging," he said.

During a ride covered by The Associated Press, the company's CTO and Xu's cofounder, Andy Fang got lost during one WeDash delivery after the app prompted him to go to the wrong address.

Yum China CEO Joey Wat said that she covertly hangs out at its restaurants, including KFC and Pizza Hut to watch customers eat, sometimes for up to three hours.

These stakeouts have been helpful in coming up with product ideas, Wat told the 2024 Fortune Global Forum this month. "Some things you can observe directly from the customer and sometimes talking to the store manager helps," she said.

Wat added that she noticed many young people in China ate KFC fried chicken dipped into mashed potato.

"What we can do with that insight is get rid of the bone," Wat said, adding this was the impetus for the company launching the boneless "mash potato burger" in China.
