Mira Murati

Mira Murati, former chief technology officer of OpenAI, surprised Silicon Valley when she resigned from the unicorn in September 2024: She had been the driving force behind ChatGPT, the revolutionary AI model. Six months later, Murati launched Thinking Machines Lab, an AI startup that’s generating buzz even though it’s still in stealth mode. But while details about the project remain thin, the 36-year-old Murati’s clout in the AI sector is clear: In mid-May, she was reportedly close to landing $2 billion in what would represent the largest seed round in tech history, valuing Thinking Machines at $10 billion.
