## About

Based in Beijing, China and established in 2019, Beijing Jianyuan Technology Co., Ltd., trading as SEPOCH, is an aerospace company that focuses on launching vehicles and other spacecraft. The company's founder and board chairman Yi Wei graduated from Beijing University of Aeronautics and Astronautics, majoring in Aerospace Propulsion Theory and Engineering. Wei previously participated in the development of launch vehicles such as the Long March 5 at research institutes affiliated with the China Aerospace Science and Technology Corporation (CASC). In 2022, SEPOCH initiated the development of reusable rocket vertical takeoff vertical landing test vehicle "Yuanxingzhe-1". In 2025, the "Yuanxingzhe-1" demonstrator rocket successfully completed sea-based recovery and reuse tests.

In September 2026, SEPOCH raised over CNY 2.30 billion in three consecutive rounds of Series B, B+ and B++ funding from IDG Capital, Shanghai Chaos Investment Group, Shanghai Songyuan Venture Capital Management and other investors.

SEPOCH's main product is the "Yuanxingzhe-1". The "Yuanxingzhe-1" is a stainless-steel reusable medium-to-large liquid-fueled launch vehicle, employing a two-stage tandem configuration, with a total length of 66 meters, a takeoff weight of 580 tons, and a first and second stage diameter of 4.2 meters each. It also provides astronautical launch services for customers in the fields of point-to-point transportation, space tourism, space station construction, space exploration, and asteroid defense.

The company's revenue is generated by developing reusable rocket launch vehicles and providing the astronautical launch services for customers in the fields of point-to-point transportation, space tourism, space station construction, space exploration, and asteroid defense. 

The company will use the funding in September 2026 to support the maiden flight mission of "Yuanxingzhe-1," validate recovery and reuse capabilities, and build commercial delivery capacity, while also advancing the R&D and engineering validation of platform-based capture and recovery technologies.
