99 Group and the quiet art of winning a property portal war
The Singapore company behind 99.co, Rumah123 and SRX didn't just out-build its rivals across Southeast Asia. Where it couldn't beat them, it bought them - and reached millions of home seekers in the process.
Most founders trying to unseat a market leader do the obvious thing: build a better version and hope people switch. 99 Group did that too - and then, when a rival's audience was too big to out-run, it simply took it over. That instinct, part product studio and part patient acquirer, is how a company started in 2014 became one of the two names that dominate property search across Singapore and Indonesia.
If you have rented or bought a home in either country in the last decade, you have probably touched one of its sites without thinking about the parent behind it. In Singapore, 99 Group runs 99.co and SRX.com.sg. In Indonesia, it runs 99.co/id and Rumah123.com, a portal so established that many Indonesians treat it as a generic verb for property hunting. Three brands, two countries, one company.
The origin01A subprime idea
The seed of 99.co is older than the company. Founder Darius Cheung has traced the idea back to 2008, when the US subprime mortgage crisis got him thinking about a strange gap: buying a home is the biggest financial decision most people ever make, and also the one they make with the worst information. Listings were scattered, prices were opaque, and the search tools felt built for filing cabinets rather than for people with lives and commutes.
Cheung was not a first-time founder. He had built tenCube, a Singapore mobile-security startup, and sold it to McAfee for about US$25 million, then spent time leading consumer mobile technology inside the acquirer. When he returned to building in 2014, he chose one of the most crowded and least glamorous corners of the internet - property classifieds - and set out with co-founders Yan Phun and Conor McLaughlin to make search feel human again.
The mission they settled on is unusually specific for a startup, and it doubles as a name. 99.co exists, in the company's words, to help "the 99%" make the best property decisions of their lives - not the sliver of luxury buyers with private brokers, but the salaried couple comparing three neighborhoods on a phone at midnight.
"Help the 99% make the best property decisions of their lives."
The product02Search built for a life, not a database
Early on, 99.co leaned into design as the wedge. Instead of a wall of listings, it offered a map-first experience, price analysis data so buyers could sanity-check what they were seeing, finance planners, and smart filters. Its most quietly clever feature let users search by commute time rather than by neighborhood or price alone - a small acknowledgment that people do not actually think in map pins; they think in how long it will take to get to work.
Behind the friendly front end sits the less visible product: data. Price trends, transaction histories, and neighborhood analytics are the stuff that turns a listings board into something people trust. That thread became central in 2020, when 99 Group acquired the Singapore Real Estate Exchange, better known as SRX, and with it the X-Value algorithm - a tool that spits out an instant estimate of what a Singapore property is worth. An honest number, delivered in one second, is a surprisingly powerful thing to own.

03When you can't beat them, buy them
Growth by product is slow. Growth by acquisition is where 99 Group's story gets interesting. Within roughly three years of launch it had become a leading portal in Singapore and pushed into Indonesia. Then, in October 2019, it did the counterintuitive thing. Rather than grind against REA Group's regional brands, it struck a joint venture that handed 99.co operational control of iProperty.com.sg in Singapore and Rumah123.com in Indonesia. REA put in about US$8 million and became a shareholder. In one move, a competitor's audience became part of the family.
You don't always have to out-run the market leader. Sometimes you buy the parts you cannot build - and inherit the audience that came with them. The 99 Group acquisition logic
In Indonesia, the company consolidated the market the same way, merging UrbanIndo into Rumah123 to create one dominant platform rather than several fragmented ones. The 2020 SRX purchase completed the pattern: buy the data layer, keep the team, fold it in. It is unglamorous work. It is also how fragmented markets get turned into moats.
The money04A cap table that raises eyebrows
For a property-listings business, 99 Group attracted a notably serious set of backers. Early rounds drew Sequoia Capital (now Peak XV), East Ventures, and Facebook co-founder Eduardo Saverin. In August 2019 it closed a US$15.2 million Series B co-led by MindWorks Ventures and Allianz X, the digital investment arm of the insurer. Its Series C brought in US$52 million in mid-2022, followed by a quieter US$11 million extension in March 2023 led by real estate private-equity firm GAW Capital Partners with OCBC NISP Ventura - pushing total funding past US$100 million.
Funding rounds (approx. USD)
What the money did not buy was a blitzscaling spectacle. While its larger rival PropertyGuru marched toward a public listing, 99 Group reported something more modest and, in its own way, harder: FY2022 revenue of about US$8.7 million, up 19% year on year, with losses narrowing. In a category addicted to the word "disruption," compounding turned out to be the plan.
05Who pays, and who doesn't
The model is the familiar marketplace two-sided setup. Home seekers browse for free. The money comes from the supply side - real estate agents, agencies, and property developers who pay to list, promote, and feature their properties, buy leads, and tap into the data and analytics tools that SRX and the portals provide. The more home seekers on one side, the more the agents on the other side have to be present. That is the flywheel every property portal is chasing, and 99 Group's acquisitions were, in large part, a way of buying more of the seeker side outright.
Two portals now dominate Southeast Asian property. 99 Group is one of them.
The market06Where it sits
The clearest way to place 99 Group is as one half of a duopoly. Its main rival, PropertyGuru, is the larger and more public of the two; alongside them sit local classifieds, agent sites, and smaller portals. What distinguishes 99 Group is less any single feature than the combination it assembled: consumer-friendly search on top of a deep data layer, spread across two of Southeast Asia's biggest property markets, stitched together from brands it either built or absorbed.

Ten years in, the through-line is patience. A company that could have chased a moonshot instead spent a decade acquiring where it made sense and polishing where it did not, in a category most investors find dull. For the salaried couple still comparing neighborhoods at midnight, that patience shows up as something simple: a search that finally behaves like it was built for them.
