Vertex Ventures China, a venture capital firm that invests in high-growth innovative start-ups across mainland China, raised nearly RMB4 billion (US$565.43 million) for a new US-denominated fund, according to a company statement on Monday. This is the largest fundraising scale since Vertex Ventures China’s independent fundraising. The new fund was oversubscribed by all overseas institutional investors due to its good investment performance and excess fund returns.
