OpenAI CEO Altman invested in 27 startups in 2023, primarily focusing on the AI and biotech sectors. Key investments included Humane and Warp, which are an AI hardware company founded by a former Apple design director and an AI startup providing developer terminals, respectively. Altman also collaborated with former Apple Chief Designer Ive and SoftBank CEO Masayoshi Son to explore new AI hardware projects. Despite not holding shares in OpenAI, his investment areas partially overlap with OpenAI's strategy, sparking controversy. Without holding shares in OpenAI, Altman remains active in the venture capital field through personal investments and funds, particularly maintaining a high level of interest in the AI sector.
