Summary
Mirendil, a startup developing artificial-intelligence tools that could vastly accelerate the pace of AI research and development, has raised $1 billion in its latest funding round, according to the Wall Street Journal. The company said Thursday that Kleiner Perkins, a venture-capital firm, and Clearlake Capital, a private-equity firm, led the Series A round.

The financing comes less than six months after Mirendil, which was founded by alumni of Anthropic, announced a $200 million seed round. The rapid succession of large raises illustrates how venture capitalists and other investors are deploying substantial sums into a concentrated group of AI companies.

The Series A round's participation from a private-equity firm alongside a traditional venture investor underscores the growing interest of larger pools of capital in frontier AI development.
