Eight months in, they’re seeking to arrange a bodily stall to fulfill rising demand
When brothers Gary Wong, 32, and James Wong, 31, have been rising up, meals was at all times a part of their lives.
They have been born right into a household of cooks who ran dim sum and zi char stalls, although these ventures by no means fairly took off. Whereas F&B was, as Gary put it, “in our blood,” their household actively discouraged the brothers from getting into the trade.
That modified at the beginning of 2026, when the brothers and their wives launched Hippopotato, a home-based rösti enterprise working out of their mom’s government flat in Tampines.
We spoke to Gary and his spouse, Yiying Tan, about how the household scaled the enterprise to promote round 150 rostis a day, producing between S$30,000 and S$35,000 in month-to-month income, with plans to open a bodily retailer quickly.
Beginning out as a canteen stall
James holds a level in culinary arts from the Culinary Institute of America—one of many world’s most prestigious establishments for aspiring cooks—by way of a joint programme with the Singapore Institute of Expertise.
Earlier than Hippopotato, he labored as the pinnacle chef at a café, giving him a firsthand understanding of the trade’s calls for: lengthy hours, capped pay, and little upside working for another person.
That satisfied him he needed to construct an F&B enterprise of his personal.
For Gary, who had spent years in non-public fairness and enterprise capital, the motivation was totally different. He noticed Hippopotato as a aspect venture at first—an opportunity to check whether or not the concept may work earlier than committing to it totally.
Gary and James’s wives would ultimately be part of the enterprise, however in its early days, Hippopotato appeared very totally different. The brothers weren’t promoting rosti but.
Their first enterprise was a cai fan (combined economic system rice) stall at a neighborhood junior school, which they secured in Jul 2025, promoting a rotating menu of as much as 16 dishes day by day.
Whereas faculties mandate that canteen distributors keep open till 2PM, the meals was nearly at all times offered out by midday. Confronted with a alternative between going house and cooking one other batch, they’d prime up, however doing so got here with a danger: something that didn’t promote by closing time would go to waste, consuming immediately into their already-thin margins.
For each greenback of gross sales we constructed from the cai fan stall, 60% was simply meals value. In case you don’t promote, you’re screwed.

The waste drawback pushed them to rethink. As an alternative of making ready meals prematurely, what in the event that they offered one thing made to order? Ideally, it could additionally attraction to junior school college students with out requiring them to prepare dinner 16 totally different dishes earlier than daybreak.
The reply got here from one in every of James’s earliest F&B jobs: a short stint at Marché’s rosti station practically a decade earlier. The brothers determined to offer the Swiss potato dish a shot at their canteen stall.
And it was the proper name. College students began queuing nearly instantly, with traces rising lengthy sufficient that the varsity principal joined in.
To handle quantity, the brothers capped gross sales at 30 parts a day, first-come, first-served—and even that wasn’t sufficient.
“It was just like the scene at these Pokémon card queues at Plaza Singapura,” Gary stated.
Escaping the bounds of the varsity calendar
The varsity canteen proved profitable for the rosti idea, but it surely got here with its personal drawback: faculties would shut for holidays. Lengthy breaks meant canteens can be empty of consumers, and there was no revenue to be made.
To fill these gaps and to keep away from being fully depending on a faculty calendar, Gary and James determined to launch Hippopotato as a home-based enterprise in Nov 2025, whereas persevering with to function the canteen corridor.
Though enterprise was gradual within the first week or two, with just one or two orders a day, enterprise picked up regularly after that.
By the brand new 12 months, momentum had constructed. Media protection adopted, whereas new menu gadgets stored prospects coming again. Orders climbed steadily from only a handful a day to a median of 100 to 150 rostis day by day.
Hippopotato operates out of Gary and James’s mom’s 1,500 sq ft government flat in Tampines, which the household shares. As Gary put it, the enterprise may be very a lot a household affair, along with his spouse, James’s spouse, and their 70-year-old mom all taking part in a job in its day-to-day operations.
Even so, Gary has not left his full-time job, saying he nonetheless sees Hippopotato as a enterprise in its early phases.
What makes a great rosti?
James’s culinary coaching formed every thing about how Hippopotato approaches the product, from the substances to the cooking course of. They solely use 100% USA Russet potatoes, and every thing, even the sauces, is freshly made on the identical day.
“If we wish to do it, we are going to do it proper,” Gary stated.
Utilizing Russet potatoes offers the rostis a crispy, golden crust whereas preserving the within moist and fluffy, Gary stated. Simply as importantly, the brothers have stored costs intentionally accessible: a rooster schnitzel with rosti prices S$12.50, in contrast with round S$35 for the same dish at Marché.
The brothers have additionally experimented with flavours such because the Salted Egg Chick rosti and Okonomirosti—a rosti topped with okonomiyaki sauce, Japanese mayo, and bonito flakes—which have develop into buyer favourites.
There are extra flavours the brothers wish to discover, however the constraints of a shared house kitchen have stored the menu tightly curated for now.
Each new merchandise provides prep work, substances, and storage necessities, whereas Singapore’s Dwelling-Primarily based Enterprise Scheme means they will’t rent workers from outdoors the family to deal with the additional workload.
That stated, for a enterprise nonetheless discovering its toes, the numbers made monetary sense.
With out lease or important overheads, the principle value is substances, and people margins are coated shortly. In comparison with the cai fan stall’s punishing 60% meals value and pre-dawn begins, operating Hippopotato from house 5 days every week gave them the room to breathe, refine the product, and construct a buyer base earlier than committing to a business area.
Forging the highway forward for Hippopotato
Taking all this into consideration, it solely made sense to the Wongs to shut the canteen stall.
Working each concurrently—the cai fan stall from the early hours of the morning till 2PM, adopted by Hippopotato’s night service and the prep work in between—was burning the household out.
The ultimate affirmation got here in the course of the Mar faculty holidays, when the canteen closed, and the staff targeted solely on Hippopotato. The expertise bolstered what they’d already suspected: the rosti enterprise delivered stronger returns, generated much less waste, and made higher use of their time.
With that, the household determined to not renew the cai fan stall’s lease when it expired in Could, selecting as a substitute to focus fully on Hippopotato.
However Hippopotato’s home-based mannequin was at all times meant to be a stepping stone, not a vacation spot. The constraints of a shared home kitchen have a ceiling, and the brothers know it.
Thus, Hippopotato has plans to open its first bodily retailer later in 2026, with a possible second location to observe. The shopper base it has constructed makes a compelling case for the enlargement: the enterprise has amassed greater than 200 five-star Google evaluations, whereas prospects journey from throughout Singapore for its rostis.
For the Wongs, it’s an indication that Hippopotato has outgrown the house kitchen the place all of it started.
