(Yicai Global) Nov. 16 -- China's largest offline data service provider, Beijing ZMT Network Technology Co., has raised CNY180 million (USD27.27 million) in its B+ financing, topping up its total B-round funding to CNY300 million, the company said online yesterday. Yunfeng Capital led the round with support from IDG Capital and Kinzon Capital.

ZMT plans to use the funds to expand its offline Big Data business and improve the quantity and quality of its data. It did not disclose its latest valuation, but did announce that its monthly revenue had increased 20-fold on the year, indicating an annual income this year of several hundred million yuan.

Last year, the firm pulled in A-round funding from Kunwu Jiuding Investment Holdings Co. [SHA:600053] and Shenzhen Haizi Assets Management Co, before obtaining A+ funds from Fosun RZ Capital and Jiuding Investment. This March, the company received over CNY100 million in B-round funding led by IDG and Kinzon, with support from Shenjing Technology Co.

ZMT Network was founded in 2013 as an offline data platform serving only the new retail sector. It helps companies adapt the new retail model by capitalizing data and currently owns China's largest offline data system.
