Although many people first associate franchise businesses with rapid branch expansion and explosive sales growth, in reality, the "number of branches" is only the visible tip of the iceberg.
The true core of sustainably growing street food franchises to a global level lies in establishing solid back-end systems, efficient supply chain management, maintaining standards that are easy to understand and implement, and continuously developing products.
At the “Trade Exponential Fest 2026,” themed ‘Grow Fast, Grow Far, Sustainably,’ organized by the International Institute for Trade and Development under the Ministry of Commerce, during the discussion “Street Food Home Run: Home Run Every Bite, Collect Delicious Points Worldwide”,
Sarath Wattanakul, Chief Marketing Officer (CMO) of Giant Exploding Fish Balls, , and Kamolchanok Manakaew, Founder & CEO of Khumsub Muang Nonth Ltd., owners of the well-known franchise brand “Heavenly Chive Dumplings by Khumsub” shared their success journeys, challenges faced, and growth strategies to inspire and guide new entrepreneurs.
Initially, Sarath explained that Giant Exploding Fish Balls began decades ago with his father, who noticed many vendors selling fried fish balls but no one had seriously branded the product. He developed a franchise system to standardize every shop, build brand recognition, and make the brand memorable to consumers, who previously didn’t know the names of fish ball stalls they frequented. Today, the brand has expanded to over 2,000 branches across Thailand.
Meanwhile, Heavenly Chive Dumplings’ Kamolchanok shared that the brand grew from the principle of "doing what you love" and her grandmother’s traditional business in Talat Phlu market. During the COVID-19 crisis, seeing that food businesses were still viable, she innovated by creatively developing traditional chive dumplings, breaking conventional norms. The brand now offers diverse menus and has expanded to over 200 branches within just two years. This rapid growth has made both brands highly focused on supply chain and back-end logistics management.
For Giant Exploding Fish Balls, franchise success hinges on three key elements: securing suppliers who support stores for life, since even missing one SKU can prevent a store from opening; managing logistics with timely deliveries, as a one-day delay means lost opportunities, rent, wages, and penalties borne by the branch owner; and creating the simplest standard operating procedure under the concept 'If you can fry a fried egg, you can sell,' reducing front-end steps to just three: tear the packet, fry, and pour the sauce.
Additionally, managing perishable and chilled ingredients with only a 20-day shelf life requires a First In, First Out warehouse rotation system. Goods are dispatched from central warehouses within 2-3 days, giving branches 17 days to sell. Free delivery is provided every 7 days within Bangkok and nearby provinces or upon meeting minimum order volumes in other provinces.
As for the key to success for Heavenly Chive Dumplings, it starts with a business model aimed at sustainable growth for Thai people, offering franchise packages with low investment and fast payback. Each package includes raw materials to sell, so if the initial stock sells out, it covers the entire package cost immediately.
Next is being an upstream producer by purchasing ingredients directly from chive farmers at fair prices, avoiding middlemen. This keeps costs low and allows franchisees to earn sufficient margins comfortably. Lastly, continuous development involves constantly surveying customer needs and addressing pain points.
The brand owner adheres to the principle of stepping back from opening branches themselves, allowing franchisees to lead market expansion, while the parent brand focuses on plugging gaps and improving back-end systems, especially food innovation.
Heavenly Chive Dumplings collaborated with Kasetsart University to transform traditional fresh chive dumplings, which had to be made at 4:00 a.m. and consumed the same day, into frozen products with a shelf life of up to one year, while fully preserving the original delicious taste.
In marketing and location selection, Giant Exploding Fish Balls targets mainly gas stations, meeting the needs of travelers seeking quick meals that can be heated in just one minute, serving as convenient snacks on the go.
Regarding pricing, both brands adopt accessible street food pricing strategies. Giant Exploding Fish Balls starts at 35 baht for size S, 50 baht for M, up to XL, which is currently the second best-selling size. Heavenly Chive Dumplings starts at 40 baht, offering pairing options for fried menu items in sizes M and L to increase ticket size.
Product innovation and adapting to trends are vital. Heavenly Chive Dumplings modernizes traditional products into snacks like chive fries or chive fish balls and launches new items every three months, including collaborations with local street food vendors by adding dipping sauce options for just 5 baht.
Giant Exploding Fish Balls responded to health-conscious feedback by developing a less sweet, spicier dipping sauce to cater to current consumer preferences. They also addressed front-of-store product display issues using a food model system, effectively reducing food waste and significantly boosting sales.
Regarding front-store challenges, both brands acknowledge that ensuring 100% quality control is tough, especially with staff who may not fry products properly or daily theft of 200-400 baht. Giant addressed this by developing a mobile check system taking just 5 minutes daily to compare actual sales with cash collected. They also hold an annual franchise partner meeting to gather feedback and elevate the brand together.
As they enter international markets, the two brands see different opportunities. Giant focuses on expanding branches and master franchises in neighboring countries like Myanmar—where they adapted flavors to local tastes—Cambodia, which responded well due to similar eating habits, and Laos, adjusting portion sizes and prices to match purchasing power. They emphasize finding local partners to handle legal and import matters.
Heavenly Chive Dumplings targets Thai restaurants abroad, especially in the United States, through distributors. They export frozen ready-to-heat chive dumplings that can be warmed in 30 seconds. They consider Florida a market as large as an entire country and plan further expansion into Asia, such as South Korea.
For those interested in starting a business, both brands offer affordable franchise packages. Giant Exploding Fish Balls ranges from a few thousand to tens of thousands baht. Entrepreneurs with existing counters can start with equipment and signage sets priced at 6,990 baht. Giant focuses on prime locations like gas stations (especially PTT stations on outbound routes), department stores, hospitals, and universities, which generate sales during one to two peak periods daily, mainly lunch to evening.
Heavenly Chive Dumplings offers a starter package at just 9,999 baht, including raw materials worth over 13,000 baht ready to sell immediately, covering investment costs and enabling immediate profit. This suits full-time employees wanting to start a side business selling via delivery from home. Target locations include community markets and mall entrances to best reach local customers.
Finally, to avoid sales overlap, both Giant and Heavenly Chive Dumplings apply the same concept: "one market, one franchise." They carefully verify locations before approving new stores to prevent franchisees from competing against each other.
However, Giant notes that since fish balls are snacks, locations with high traffic, like three adjacent gas stations, can all generate good sales because consumers typically stop at one preferred station. This flexible location management suits today’s street food business environment perfectly.
At the end of the discussion, both brand executives advised entrepreneurs that exporting abroad is not as difficult as it seems. Each country can be viewed as a province—for example, sending goods to Laos is like shipping to Nong Khai province, requiring customs clearance; sending to the US is like shipping to northern Thailand, needing complete documentation.
The most important thing is to take action, learn from mistakes to find the winning zone, maintain consistent product standards, and leverage government agencies ready to support Thai street food for sustainable growth on the global stage.
In summary, successful and sustainable street food franchise businesses depend not just on “deliciousness” or temporary trends but on building strong back-end systems, efficient supply chain and logistics management, and continuous adaptation and innovation. This enables brands to expand nationwide and confidently establish Thai street food on the world stage.
