Two funding stories about AI leaving the screen: a manufacturing data platform that reads engineering drawings, and a drone autonomy company chasing a $20 billion price for pilots that never sit in the cockpit. CADDi raised $114 million in a Series D that values the Tokyo- and Chicago-headquartered company at $1.2 billion, more than double the $470 million it carried in March 2025.

Agent safety is turning into an industry with a business model. Today's money went to the auditors and to the plumbing under the agents themselves. AIUC closed a $40 million Series A led by Ribbit Capital, with First Harmonic participating, to sell enterprises an independent safety verdict on the agents they buy.

Euclyd, an Eindhoven chip startup founded in 2024, closed a Series A of more than €200 million (about $231 million) co-led by Samsung, Somerset Capital Partners, the EQT-managed Scaleup Europe Fund and Innovation Industries, the company announced on September 15. Rounding out the syndicate are EIFO, imec.xpand, the Brabant Development Agency and Quadri.

Tokyo's NAND maker is shopping for US capital at an awkward moment — the stock is down more than half from its peak, and the market's memory trade has turned. Kioxia is weighing a US share sale of $10 billion or more, targeting an American Depositary Receipt listing as early as spring 2027. Bloomberg reported the plan on September 14, citing people familiar with the matter.

Two research results and one big European round: distillation gets a smaller vocabulary, physical AI gets open hardware, and embedded-device security gets unicorn money. Meta FAIR found the way to break the distillation ceiling is to shrink the vocabulary to 256 bytes. A paper posted to arXiv on September 11 (authored with a University of Washington team) trained 1.28-billion-parameter byte-level students — models that predict raw bytes instead of tokenizer chunks — from larger teachers, and…

Two hardware stories on the same day from opposite directions: OpenAI quietly bought the camera brain it doesn't have, while Apple put a price tag on the camera brain it does. OpenAI has reportedly bought Glass Imaging, the startup whose neural image processing software already ships in Honor smartphones, for more than $300 million. The Wall Street Journal first reported the deal, and neither company has confirmed it.

Monday's news ran from the inside of the AI rack to the inside of the White House — a networking challenger that says the GPUs are not the bottleneck, a private Altman-Trump meeting that surfaced the same day the two split publicly on slowing down, and a mathematician's attempt to say what the profession should be for. Cornelis Networks announced roughly $205 million in funding alongside Active Compute Fabric, an open networking architecture that puts programmable compute inside the fabric…

Monday afternoon's money went into the least glamorous part of the AI stack — the part with a regulator attached. Stockholm's Tandem Health landed Europe's biggest clinical-AI round to date, Waymo opened its doors in Las Vegas, and Akuity made the case that agents need an identity before they get a production deploy. Tandem Health raised a $100M Series B led by the Scaleup Europe Fund, the €5 billion vehicle the European Commission put EQT in charge of this year.

Two funding rounds on opposite ends of the AI stack today: one selling the plumbing that keeps agents alive, one selling music toys that refuse to prompt a model at all. Temporal raised $550 million in a Series E at a $12.55 billion valuation, and the reason it gives is duration. A year ago the company says most of its customer conversations were about payments, onboarding and fulfillment; now customers want agents that run for days, weeks or months without losing state.

Hot Chips 2026 wrapped with a memory bet, and the funding calendar is unusually busy for a Monday. d-Matrix says stacking memory directly on the compute die beats HBM by 20x on bandwidth density. The startup's Raptor accelerator puts a TSMC N4 logic die face-to-face on top of custom 3D DRAM and claims roughly 100 TB/s per card at 32 GB — against a practical ceiling of about 20 TB/s for today's HBM4 packages, which d-Matrix attributes to limited package "beachfront" and raw physics: driving 100…

The week AI's biggest labs spent asking for permission to slow down ended with one of them telling shareholders the money is very good — and the number attached to that claim reframes the entire pacing debate. Anthropic has told shareholders its adjusted operating income will be positive for a second straight quarter, with gross margins above 80%, according to the Financial Times, which sourced the report to multiple people with knowledge of the matter.

The pacing debate moved markets all morning. Now it has a counterweight: the biggest public-market test of the AI buildout, roadshowing this week in the least likely place. Firmus Technologies is seeking to raise up to $5 billion (A$7 billion) in an initial public offering, targeting an October launch with a debut on the Australian Securities Exchange as early as late October.
