The platform lets buyers, renters and agents search HDB resale flats, executive condos, condominiums, landed homes and new-launch projects for sale and rent, with map-based search, transaction data, agent directories, mortgage tools and nearby-amenity insights (MRT, schools, commute times). 99 Group is backed by investors including Sequoia Capital, 500 Global, Golden Gate Ventures, Quest Ventures and East Ventures.
