Most entrepreneurs who appear on Shark Tank Vietnam see it as their one big chance to grab funding. The show puts them in front of wealthy investors and millions of viewers. The pressure to accept any deal, even an imperfect one, can be overwhelming. Yet in 2017, Atadi.vn broke that script. Founder Dr. Nguyễn Văn Phong stood firm when Shark Nguyễn Xuân Phú made an offer, and he rejected it on the spot.
To many people watching at home, it looked reckless. Who turns down money on live television? But what appeared to be a setback turned into the foundation for something bigger. Within a year, Atadi had merged with Vntrip in a deal worth about 100 billion VND. That move not only validated the founder’s decision but also created a new kind of player in Vietnam’s online travel industry.
The Genesis of Atadi.vn: A Vision to Disrupt Travel
Atadi.vn was born in 2013 out of frustration with Vietnam’s slow and complicated flight booking system. At the time, many travelers relied on traditional agents or clunky airline websites. Prices were often unclear, and hidden fees made it difficult for customers to know the true cost of their tickets.
Dr. Nguyễn Văn Phong, who had earned a PhD in aviation technology from Ukraine, saw the inefficiency as an opportunity. He believed that with the right algorithm, booking flights could be almost instant. That belief shaped the DNA of Atadi. The company promised to deliver cheap airfares in just ninety seconds, thanks to its proprietary fare-comparison and ticketing technology.
This was not just a nice-to-have feature. In a market where low-cost carriers like Vietjet Air were gaining popularity, speed and transparency gave Atadi a huge competitive advantage. By focusing narrowly on low-cost flights, it carved out a niche that neither global booking giants nor traditional agencies could match. By the time it appeared on Shark Tank, Atadi had already built a reputation as a reliable “go-to” platform for bargain flight hunters in Vietnam.
Shark Tank Vietnam 2017: The Offer and the Refusal
When Atadi entered Shark Tank Vietnam in 2017, the founder made a confident pitch. He asked for 27 billion VND in exchange for 15 percent equity, valuing his company at around 180 billion VND. That was an ambitious ask, but it reflected his belief in the technology and the traction Atadi had achieved.
Only one shark responded with a counteroffer. Shark Nguyễn Xuân Phú was interested, but his terms were tough. He offered the same 27 billion VND but demanded 45 percent ownership. That counter instantly slashed Atadi’s implied valuation to about 60 billion VND, one-third of what the founder had set.
The moment was tense. For a startup, 27 billion VND could accelerate growth and allow expansion into new areas like hotel bookings. Yet accepting the offer meant giving up nearly half the company. It would also put control of Atadi’s future direction into the hands of the investor.
Dr. Phong made his decision quickly and clearly: he said no. Viewers were shocked. Refusing capital on national TV went against the very spirit of the show. But beneath the drama was a strategic calculation. The founder believed his company was worth more, and history proved him right.
The Aftermath: Visibility as a Growth Engine
Walking away without a deal might seem like a dead end, but in Atadi’s case it created new momentum. The Shark Tank appearance gave the startup enormous exposure. Millions of Vietnamese viewers now knew the name “Atadi.” Even though the company did not secure funding, it walked away with brand recognition that money could not buy.
This visibility mattered. In the competitive world of online travel, where global giants like Booking.com and Agoda dominated advertising channels, appearing on prime-time television helped Atadi stand out as a local challenger. Customers who had never heard of it before began trying its service. Investors and strategic partners also started paying attention.
Among them was Vntrip, a fast-growing hotel booking company. Vntrip had already raised millions of dollars in funding and wanted to expand into flight booking. The Shark Tank episode introduced Atadi as the perfect complement. What looked like a failure to outsiders was in fact the start of a much bigger opportunity.
The Vntrip Merger: Validation at 100 Billion VND
In 2018, the partnership became official. Vntrip and Atadi merged in a deal that valued Atadi at around 100 billion VND. The figure dwarfed the valuation implied by Shark Phú’s rejected offer. For Dr. Phong, the decision to walk away on live TV had paid off handsomely.
The merger made perfect sense. Vntrip had strengths in hotels, with a network of more than 12,000 domestic properties and access to over one million international hotels. What it lacked was a strong flight-booking arm. Atadi filled that gap. Its fast and transparent ticketing technology allowed Vntrip to become a true online travel agency that could serve every part of a traveler’s journey.
Dr. Phong stayed on after the merger, helping to integrate Atadi into Vntrip’s ecosystem. He remained for more than two years, ensuring that the technology scaled smoothly and that the vision of cheap, transparent airfares stayed intact. Eventually, he stepped aside to pursue new ventures in areas like cloud computing and artificial intelligence. His exit was not abrupt; it was a planned transition that ensured Atadi’s DNA would continue to shape Vntrip’s future.
Reinvention: From OTA to Corporate Travel Powerhouse
After the merger, Vntrip realized it needed to evolve beyond being just another online travel agency. Competing directly with Agoda and Booking.com on consumer promotions was a losing battle. Those companies had massive marketing budgets and global reach.
Instead, Vntrip shifted its focus toward the business-to-business segment. It launched Vntrip TMS (Travel Management Solution), a platform designed for corporate clients. With TMS, companies could handle flight bookings, hotel reservations, and travel expense management on one integrated system.
Atadi’s flight technology was crucial here. It allowed companies to get fast, accurate, and low-cost flight options for their employees, all under centralized control. This shift to corporate travel created a more stable revenue stream. Unlike consumer travel, which is driven by promotions and discounts, corporate travel values reliability, service, and cost control.
By 2023, Vntrip TMS was serving more than 1,500 corporate clients, including global names like Unilever and local giants like FPT. The company also claimed to have achieved positive cash flow, proving the model was working.
Competing with Global Giants: A Local Advantage
The rise of Vntrip was not just about smart business pivots. It also involved standing up to foreign competitors in ways that shaped the entire industry. In 2016, before the Atadi merger, Vntrip’s CEO, Lê Đắc Lâm, accused Agoda of avoiding taxes in Vietnam. He argued that foreign platforms were not paying VAT or corporate income tax on commissions earned from Vietnamese customers.
The accusation made headlines and eventually pushed the Ministry of Finance to act. New rules required foreign online travel agencies to pay taxes in Vietnam, leveling the field for local companies. It was a rare moment when a startup influenced government policy in its favor.
As Lâm explained in an interview:
“There is nothing that cannot be sold. The key is the right price.”
That philosophy reflected not only his belief in business strategy but also his approach to competition. By making noise about fairness, Vntrip positioned itself as a defender of local interests against foreign giants.
Where Is Atadi.vn Today?
Even after the merger, Atadi did not disappear. The Atadi.vn website continues to operate as a specialized low-cost flight booking platform. It still carries the brand identity it built before Shark Tank, serving budget travelers who want quick access to cheap fares.
In 2025, Atadi also resurfaced in a new form: Atadi AI, a booking assistant on Zalo. With simple chat commands, users can now find and book flights through a familiar messaging app. This shows that Atadi’s innovative spirit remains alive. Even though the brand is part of a larger corporate structure, it continues to evolve with new technology trends.
Lessons for Entrepreneurs: The Power of Saying No
Atadi’s story holds a clear lesson for entrepreneurs. Not every deal is worth taking, even if it looks tempting in the moment. By refusing an undervalued offer, the company preserved its independence and later secured a deal on better terms.
This decision was not only about money. It was about control, vision, and belief in the product. Entrepreneurs often feel pressured to accept the first check that comes their way. Atadi proves that patience and confidence can lead to better outcomes.
The second lesson lies in adaptation. Atadi alone might have struggled against international competition. But by merging with Vntrip, its technology found a bigger stage. Together, the companies pivoted toward corporate travel, a segment where they could win.
A Legacy in Motion
Atadi.vn’s journey is a story of resilience, strategy, and bold decision-making. From its humble beginnings as a scrappy low-cost flight platform, to the high-stakes rejection on Shark Tank, to its merger that redefined Vietnam’s travel-tech landscape, Atadi left a legacy far larger than its original size.
Today, its brand lives on, its technology powers corporate travel, and its founder’s decision to walk away from the wrong deal continues to inspire. In the world of startups, success is rarely a straight path. Atadi’s story proves that sometimes the smartest move is not grabbing the first lifeline, but swimming toward the bigger opportunity waiting just beyond the spotlight.
TL;DR (Too Long; Didn’t Read)
Atadi.vn rejected a Shark Tank Vietnam deal, then merged with Vntrip at about 100 billion VND and became the flight tech powering Vntrip’s corporate travel growth. The brand still runs consumer flights while its technology anchors Vntrip’s Travel Management Solution for 1,500 plus companies.
