If you’ve spent more than five minutes on TikTok lately, you’ve definitely heard it. That high-pitched, almost cartoonish squeal: "Thank you, Kateyki!" It’s usually followed by a stoic bodyguard in a mask holding ten shopping bags or opening the door of a neon-colored Lamborghini. Aon Somrutai—now legally Somrutai Rattanawaraha—has basically become the internet's favorite "rich girl" caricature.
But as her follower count climbs into the millions, the same question keeps popping up in the comments: Is she actually that rich, or is this all just a very clever marketing play?
Honestly, the answer is a bit of both. It’s a mix of genuine business success, a high-profile marriage, and a "new money" persona that’s been dialed up to eleven for the sake of the algorithm.
Who Exactly Is Aonsomrutai?
Before she was a global meme, Aon was a girl from a "normal family" in Thailand. She’s been very open about her background in recent interviews, specifically with Harper's Bazaar. Her father was a soldier with a modest salary, and her parents separated when she was 14.
She wasn't born with a silver spoon.
She started her first online business at 17 because she wanted to buy the luxury bags she saw in magazines. She eventually moved to Sweden to study at Karlstad University, focusing on sustainability and innovation. This wasn't just for show; it actually formed the backbone of her primary source of wealth.

The Sources of Her Wealth
Aon isn't just "famous for being famous." She’s a legitimate entrepreneur. Her wealth primarily comes from three distinct buckets:
1. The Luxury Resale Empire
Aon is the founder of Perrine Porter and SF Brandname. These aren't just small Instagram shops; they are major players in the Thai luxury resale market. She leveraged her obsession with designer gear into a business model that promotes "sustainable luxury." Basically, she buys and sells pre-owned high-end items.
The "I'll take this one, and this one" routine you see in her videos? It’s a genius marketing strategy. Every time she "shops" in her own stores, she’s showcasing inventory to millions of potential buyers.
2. Marriage to a Celebrity Surgeon
In February 2025, Aon married Dr. Nopparat Rattanawaraha (popularly known as Mor Song). If you aren't familiar with the Thai social scene, Mor Song is one of the most famous plastic surgeons in the country. He owns the Nopparat Cosmetic Clinic, which caters to the elite and celebrities.
Their wedding was a massive affair, even receiving blessings from the Thai Royal Family. While Aon was already successful on her own, marrying a man with his own established empire certainly didn't hurt her financial status.

3. Digital Influence and Music
With over 6 million followers on TikTok and nearly 2 million on Instagram, her "influence" is worth a fortune. She’s collaborated with Lisa from BLACKPINK and BamBam from GOT7. She even released a single called "Thank You Kateyki (Lalala)" that G-Dragon supposedly vibed with. In the world of 2026 social media, that kind of reach translates into massive brand deals and appearance fees.
Is the Lifestyle "Fake"?
People often point to her bodyguard, Kateyki (whose real name is Tae), and her housekeeper as "props." In a way, they are.
Aon has admitted that the "Kateyki" persona started because she needed someone to film her while she was shopping. She hired a security guard from a firm because her stores were getting crowded, and the dynamic just clicked. The high-pitched voice and the exaggerated shopping sprees are definitely a "character," inspired by her childhood love for Barbie and Disney princesses.
"I wanted to make people happy... maybe in the future you can see me as an actress, because I love new challenges." — Aon Somrutai in her Bazaar Singapore interview.
She’s playing a role. She’s leaning into the "excessive" lifestyle because it’s what the internet wants to see. Does she own luxury cars? Yes. Does she shop at Louis Vuitton with Lisa? Yes. But the way she presents it is 100% theater.

The Reality Check
Is she "Forbes 50 Richest in Thailand" rich? No. If you look at the 2025/2026 wealth rankings for Thailand, the list is dominated by the Chearavanont and Yoovidhya families (the Red Bull and CP Group empires). Aon doesn't have billions of dollars in the bank.
However, she is "top 1%" rich. She’s a multi-millionaire who has successfully merged a luxury resale business with a viral personal brand. She lives in a massive mansion, travels via private jet or helicopter (like her engagement in New Zealand), and has access to circles most people can only dream of.
What Most People Get Wrong
The biggest misconception is that Aon is just a "spoiled brat" spending her parents' money. It’s actually the opposite. She built her brand from the ground up as a teenager.
She’s also much smarter about business than her "dizzy" online persona suggests. By using "Kateyki" as a sidekick, she created a brand identity that is instantly recognizable. Even if you don't speak Thai, you know the catchphrase. That is world-class branding.
Actionable Insights for the Curious
If you're looking to understand why Aonsomrutai is so successful—or if you're trying to figure out if her wealth is "real"—keep these points in mind:
- Look at the business, not the bags: Her wealth is anchored in the circular economy. Buying and selling pre-owned luxury is a booming industry, and she’s at the forefront of it in Southeast Asia.
- Study her "Meme-ification": She proved that a catchphrase is more valuable than a high production budget. Her "Thank You Kateyki" videos are often shot on a phone, but they have more engagement than multi-million dollar ad campaigns.
- Separate the Art from the Artist: Aon the Businesswoman is serious and focused. Aon the Influencer is a Barbie-inspired character. Don't confuse the two.
Whether you find her "annoying" or "iconic," there’s no denying that Aonsomrutai has successfully gamed the system. She’s wealthy, she’s savvy, and she’s definitely laughing all the way to the bank.
