China’s largest co-working office space operator UrWork has raised a RMB300 million (US$43.5 million) investment round from property developer RK Properties and existing investor Jingrong Holdings, according to the company’s announcement. The new financing round came two months after the three-year-old start-up raised an undisclosed series C+ financing round in June, valuing the company at around US$1.8 billion. With this strategic cooperation with RK Properties, UrWork will play the innovative role of new space content operators, and help traditional office space upgrades in areas of content filling, space community creation, and business operation and maintenance.
