齐向东 / Qi Xiangdong

Overview

齐向东 / Qi Xiangdong appears in No.216 ⚔️ 「十步杀一人」：红衣大炮周鸿祎的三十年全面战争史 | 中国互联网故事 27 as the founder associated with early Qihoo and as the executive counterpart to 周鸿祎 during the Qihoo 360 platform-war and later security-business period.

Current Profile

The source uses Qi as an operating and organizational node rather than as the central biography. He matters because Qihoo’s search-to-security turn, the 3Q crisis narrative, and the later Qianxin separation make the company less reducible to Zhou’s public persona alone.

Key Characteristics

• Qihoo-side founder/operator figure tied to the company’s pre-360 and security-software formation.
• Crisis participant in the episode’s 3Q account, including the report to Zhou that police had come to the company.
• Enterprise-security branch figure because the source says Qianxin separated from 360 and the two sides later became competitors.

Evidence

• Early company role: No.216 ⚔️ 「十步杀一人」：红衣大炮周鸿祎的三十年全面战争史 | 中国互联网故事 27 says Zhou joined Qi Xiangdong’s Qihoo after leaving Yahoo and that Qihoo initially worked on search before turning toward rogue-plugin cleanup and 360 Security Guard.
• 3Q crisis role: No.216 ⚔️ 「十步杀一人」：红衣大炮周鸿祎的三十年全面战争史 | 中国互联网故事 27 says Qi told Zhou that more than 30 police officers had come to the company during the Tencent conflict.
• Security-business separation: No.216 ⚔️ 「十步杀一人」：红衣大炮周鸿祎的三十年全面战争史 | 中国互联网故事 27 says Qianxin became independent and that by 2019 360 and Qi no longer had an equity relationship, turning the sides into competitors.
