About Sezhang SDG

Sezhang SDG, legally registered as Shanghai Sezhang Network Technology Co., Ltd., is a digital brand marketing and management group established in 2016. The company was founded by Jennifer Qian Haohao, who identified the commercial potential of content-driven marketing on social platforms like Xiaohongshu (Little Red Book) early on. Qian, a Donghua University graduate in Fashion Design and a London College of Fashion alumna in Fashion Management, launched the company after her initial entrepreneurial ventures in London.

The firm initially focused on providing e-commerce and brand account operations on Xiaohongshu, quickly attracting its first set of brand clients by 2017. Sezhang SDG has since evolved into a comprehensive marketing service provider, incorporating MCN (Multi-Channel Network) incubation, advertising strategy, and brand ad placement. The business operates on a dual model, offering brand traffic services and managing its own proprietary brands. Its service division assists clients with brand building and market entry, leveraging data-driven strategies for platforms like Xiaohongshu and Douyin. The company has developed an in-house influencer management platform, "Naoshi," which serves as a key tool for managing campaigns for over 500 brands.

Revenue is generated through full-service operational support for other brands and through the sales of its own incubated product lines. The company has successfully launched its own cosmetics brand, OUT OF OFFICE, which achieved over RMB 100 million in sales in its second year, and a natural fiber womenswear brand called Yangzhidao. Sezhang SDG caters to a wide range of clients, from domestic startups to international giants like P&G, LVMH, and Xiaomi, across sectors including luxury, beauty, fast-moving consumer goods, and 3C electronics.

The company's growth has been supported by significant funding, including a Series A round of RMB 30 million led by SIG Asia Investment and a Series A+ round of RMB 100 million led by the Bocom-OCBC Digital Economy Fund. This capital is being used to enhance its social content management platform, expand its team, and invest in its influencer traffic management systems.
