Nous Research Raises $90M With Trump Jr. Firm on Cap Table

Image
By Daniel Rao The most interesting name on the cap table of this week's buzziest AI funding round isn't Nvidia. It's the Palm Beach venture fund where Donald Trump Jr. is a partner — and it has just bought into a lab famous for shipping open-weights AI models without content filters. Nous Research confirmed on Wednesday that it has closed a $90 million Series B at a $1.5 billion valuation, launching "Hermes for Businesses" to take its viral open-source AI agent into corporate America. Robot Ventures led the round, with Nvidia, Samsung, Microsoft's M12, Union Square Ventures, Menlo Ventures and 1789 Capital — Trump Jr.'s fund — among the backers. Total funding now stands at about $158 million. TechCrunch first reported in July that Nous was in talks to raise at least $75 million at the same valuation; the final figure came in bigger, and now it's done rather than rumoured. We checked TechPulse USA's own archive before writing this — no earlie...

Nadella Says Assume Every AI Model Is Already Compromised

Image
SATURDAY, October 10 — The man who sells AI to more businesses than anyone else on Earth just told the world to stop trusting it. Satya Nadella, Microsoft's chairman and chief executive, published an essay on X on Saturday morning titled "Models as Insider Risks in the Super Intelligence Era".

And put an emergency brake in human hands, so an authorised person can stop a model mid-task. He posted it on a Saturday morning — not a Tuesday product launch, but the weekend hour when a chief executive is thinking out loud. And what he is thinking, apparently, is that the industry's entire trust model is broken. Satya Nadella at the White House tech leaders' dinner hosted by President Donald Trump, September 4, 2025 — roughly a year before the Microsoft CEO would publicly urge companies...

Firmus axes $5.5B IPO after 'greedy' A$44B valuation revolt

Image
By the TechPulse USA News Desk They didn't cut the price. They didn't delay the listing. Firmus — the Nvidia-backed Australian data centre company that wanted to go public at a A$43.9 billion valuation, the biggest Australian float since Telstra in 1997 — killed the whole thing on Friday morning. One week the books were "indications of interest well above the offer size." The next, the company walked away and blamed "recent market volatility." Read the second sentence again: a A$44 billion company does not need market volatility as an excuse. What it needed was buyers. It didn't have them. We pulled the Reuters, Nikkei and Straits Times versions of Friday's announcements side by side before writing this — the facts line up, which matters because this story has been spinning for a week and the numbers keep getting rounded in different directions. What follows is what actually happened to Australia's most hyped IPO, who got burned, and what it ...
