The startup's own stack for Africa and Middle East is now handling more than 17,000 calls per day.

Layup Parts co-founder Zack Eakin has drawn on a motorsports background, and his experience working for Palmer Luckey and Elon Musk, to tackle making faster, cheaper, and better composites.

Another fusion startup has raised another a massive round to make this type of power a reality.

A Google Sheets add-on with 4 million installs has been silently sending your spreadsheet cell data to OpenAI. Hacker News discovered this 9 days ago, when a PromptArmor security report went viral. Last night — when any normal HN story would be decaying into oblivion — it exploded a second time, gaining 59 points and 23.9% in a single day. I track Hacker News every day. I've seen 518 posts come and go over 319 days of systematic monitoring. Most stories follow a predictable death curve: peak on Day 1, bleed points for 2–3 days, then vanish from the Algolia search layer entirely. A post that survives 5 days is exceptional. One that accelerates on Day 9 is something else entirely. Here's the trajectory: 104 → 106 → 148 → 199 → 219 → 247 → (gap) → (gap) → 306 points. Over 9 days, that's a +194.2% total gain. But the real story is the shape of the curve. From Day 5 to Day 6, it added 20 points. From Day 6 to Day 7, roughly 28. Then on Day 9, it jumped 59 points — a single-day increment that's 2–3x the earlier daily gains. 109 comments and counting. This isn't normal HN physics. This is a second wave of attention — the kind that happens when a story percolates through social media and circles back to the search layer with amplified urgency. People didn't just read this and move on. They came back. The vulnerability itself is brutally simple: ChatGPT for Google Sheets, a popular add-on that lets you use GPT inside spreadsheets, sends cell contents to OpenAI as part of every API call. The PromptArmor research documented specific data flows — workbook data that users never intended to share, flowing to OpenAI's servers as part of "context." No breach required. No malicious actor. Just the plugin working as designed, with a data-sharing envelope nobody bothered to read. I've spent 319 days cataloging every AI security signal that hits HN's front page. Patterns emerge when you watch this long. The data is unambiguous: application-layer AI security is the most underserved mark

Every founder who applies to Startup Battlefield wants the same thing: the Disrupt Main Stage. Here’s how to get there and why the opportunity starts well before the main stage.

In a wild ride for 22-year-old founder and CEO Ethan Thornton, Mach Industries has raised another $300 million. It already has five autonomous vehicles in development and completed a major acquisition.

Anthropic has closed a $65 billion Series H round at a $965 billion post-money valuation, marking what could be the AI startup's final private fundraise before a highly anticipated IPO.

CEO Ariel Katz argues that while AI can replicate workflow SaaS, it can't copy H1’s unique doctor data.

After overwhelming demand from founders around the world, TechCrunch has extended the Startup Battlefield 200 application deadline to June 8. Nominate a standout startup or apply yours today.

Canadian authorities on Wednesday arrested a 23-year-old Ottawa man on suspicion of building and operating Kimwolf, a fast spreading Internet-of-Things botnet that enslaved millions of devices for use in a series of massive distributed denial-of-service (DDoS) attacks over the past six months. KrebsOnSecurity publicly named the suspect in February 2026 after the accused launched a volley of DDoS, doxing and swatting campaigns against this author and a security researcher. He now faces criminal hacking charges in both Canada and the United States.
