Not long ago, nearly a dozen top-tier funds took the initiative to reach out to BrainCo, expressing their desire to acquire its existing shares. Many more institutions were turned down with courtesy. Liu Dan, an early investor in BrainCo, disclosed in an interview that the number of inquiries has been steadily climbing, with some potential buyers even willing to pay prices above those of the latest investment round.
