Busiest venture firms did more Q3 deals while total funding fell, Crunchbase data shows

Andreessen Horowitz, Insight and Sequoia were among at least 22 investors in 10 or more Q3 venture rounds, most of them doing more deals as funding fell. Crunchbase ties the lower total to the absence of new record AI megarounds, while its lead-investor dollar rankings turn on a few multi-billion checks.

Risotto launched an agent for ambiguous Tier-2 IT tickets that saves each new fix as a runbook, and says its customers auto-solve 40% to 90% of tickets. Its bet is that the knowledge from a hard fix, usually lost in a closed ticket, can be kept and run again.

Same-model rewording costs SlopShape's structural AI detector 0.9 points of F1

Sitefire's SlopShape spots AI-written company blog posts at 97.0% macro-F1 from page structure alone, and at 96.1% after each model rewords its own output. Paraphrasing generated copy hides little from it, though the test reworded text without reordering any page's sections.
