The Atlas Scout program hopes to leverage students' own campus networks to help these early entrepreneurs obtain capital, mentorship, and industry resources. Eligible entrepreneurial teams will also have the opportunity to connect with YZi Labs' EASY Residency program or further discuss investment collaboration.The Atlas Scout program not only expands financing and resource channels for early entrepreneurs but also allows participating students to accumulate venture capital experience through practical projects, enhancing their project evaluation, founder communication, and investment judgment skills.YZi Labs stated that Scouts can independently carry out campus activities based on their interests, such as organizing technical exchanges, gathering entrepreneurial teams, or discovering potential investment projects, while receiving guidance and ecosystem resource support from YZi Labs in the process. The program aims to establish connections before entrepreneurial projects gain widespread attention, allowing initial ideas on campus to have the opportunity to develop into actual projects, while cultivating a new generation of investors who can identify technological trends and entrepreneurial potential earlier.
