Financing and Investment - Maijizhi Bio has successfully raised over 700 million RMB through multiple financing rounds since its establishment, achieving a post-investment valuation of 2.64 billion RMB after the Pre-IPO round in 2025 [10]. - Some early investors have begun to exit, with significant share transfers occurring prior to the company's IPO application, indicating potential investor concerns about the company's future [10].
