Walnut Coding, as the firm is known, could seek to raise about US$100 million in a US listing, the people said, asking not to be identified because the deliberations are private.
Other firms exploring listings include computing infrastructure provider Shenzhen Cloudsky Technologies and software service platforms Zaihui and Zhonghe Group, the people said. Those three companies may seek to raise similar amounts, they added.
No final decisions on the share sales have been made and the companies may decide not to proceed, the people said.

A representative for Walnut Coding, whose backers include private equity firms KKR & Co and Hillhouse Investment, declined to comment. Zaihui, Zhonghe and Cloudsky did not respond to requests seeking comment.
