Weekly AI Startup Funding: September 28-October 4, 2025
I startups raised over $3.2 billion this week, with record-breaking deals spanning AI infrastructure, enterprise automation, and scientific discovery. From Cerebras’ massive $1.1 billion Series G to pioneering ventures in autonomous science labs, here are the highlights.
Interesting seeing how much of the capital flow is now clustering around AI infrastructure and operational layers rather than just model capability itself.
Feels like the field is increasingly realizing deployment/runtime behavior is becoming just as important as model intelligence.
