The founder's own announcement (@bneyshabur) and the lead investor's official post (@a16z) corroborate every element of the claim: $200M round, led by a16z and Kleiner Perkins, NVIDIA investing, a 20-person founding team from Anthropic, xAI, DeepMind, and OpenAI, and the self-accelerating AI R&D mission confirmed on the Mirendil website. The only minor discrepancy is that a16z's post names founder origins as Anthropic, Google DeepMind, and xAI, while the founder explicitly includes OpenAI among the broader 20-person founding team's institutions, fully matching the claim.
