The week in startup news: Sep 14-20

1. Cornelis Raises $205M vs Nvidia

Cornelis, a company spun off from Intel in 2020, raised $205 million led by IAG Capital Partners to build networking tech for AI chips. Its new Active Compute Fabric product targets wasted GPU time by letting chips process and send data at the same time, and it's positioning itself against Nvidia with an open architecture that works across different GPU hardware.

2. Superhuman Buys Notetaker Fathom

Superhuman acquired Y Combinator-backed Fathom instead of building a notetaker in-house. Fathom, founded in 2020, had raised over $30 million and was valued at $94 million in 2024. The move fits a bigger push by productivity platforms to have AI proactively act on what's discussed in meetings, not just wait for prompts.

3. A Vinyl Bar in Shibuya Raises $5.5M for Music AI

A Vinyl Bar in Shibuya raised a $5.5 million pre-seed round from a long list of investors including Mantis VC, SV Angel, and BoxGroup. The startup, founded by Máuhan M. Zonoozy, is building small apps for playing with AI-generated sounds and vocals in the style of any artist. A former Spotify chief content officer joined as an advisor.

4. Microsoft Sets an AI Code of Conduct

Microsoft released a document guiding its AI models away from dangerous behavior, including not hacking systems or tricking humans. It's more about values and training red lines than a broad policy statement, and it opens with a prediction that superintelligent AI systems will surpass human performance at most tasks within a decade.

5. Daydream Adds Siri Shopping

Daydream, an AI fashion discovery app, launched two features built on Apple's new iOS 27 developer tools. One lets users shop outfits straight from photos already saved in their camera roll, and the other lets people search for clothing through Siri without opening the app at all.

6. ClickFix Scams Are Spreading Fast

ClickFix attacks trick people with a fake CAPTCHA or anti-bot checkbox that, once clicked, gets them to run commands that hack their own device. What used to be rare has become one of the fastest-growing cybersecurity threats of 2026, spreading through both fake sites and hacked legitimate ones.

7. Insight Partners Bets Beyond OpenAI and Anthropic

Deven Parekh, who has co-run Insight Partners for 26 years, spoke about why the firm keeps a diversified strategy even as much of venture capital piles into OpenAI and Anthropic. Insight has led rounds in Databricks and holds stakes in both major AI labs, but Parekh was candid about deals the firm missed too, including Legora.

8. macOS 27 Gives Siri New Powers

macOS 27 Golden Gate ships an updated Siri AI with access to Mac-specific context, alongside design changes to windows and icons. It's entering a space where most browsers already offer sidebar AI assistants and apps like Highlight and Littlebird already track your work context to be useful.

9. Waymo Opens Robotaxis in Las Vegas

Waymo began letting the public ride its robotaxis in Las Vegas just weeks after getting final approval from Nevada regulators, following the same rollout playbook it has used in 14 other cities. It's starting with dozens of new Ojai minivans covering part of the Strip and Boulder Junction, with public riders needing an invite for now.

Why This Matters If You're Building

This week shows two tracks moving at once: heavy capital and safety rules forming around frontier AI infrastructure, and small teams still shipping fast on new platform tools like iOS 27 and macOS 27. Whether you're raising, building, or just trying to keep your product secure, there's a real precedent here worth studying, not just headlines to skim past.
