A leading global startup pre-accelerator, which offers a 12-week program designed to prepare founders to build investment-ready startups, has secured $320 million in new funding. The program aims to establish itself as the Ivy League of startup training camps. Located in San Francisco, the incubator is known for its highly competitive admission process, described as more selective than Harvard University. Founders participating in the program have faced challenging conditions, including sleeping in tents and closets, while collectively raising $2 billion in venture capital funding.
