Article Summaries:

  • Y Combinator’s Fall 2025 cohort signals a pivot from AI as a feature to AI as a platform. 92 % of the 155+ startups embed AI in their core products, but the focus is now on the infrastructure that deploys, operates, and scales AI agents, physical robots, and vertical applications. 13 companies are building production‑ready stacks for AI agents, while others develop training environments for autonomous robots, addressing the scarcity of real‑world data. In fintech, six firms are moving AI agents from simple assistants to end‑to‑end workflow owners, automating tasks from deal sourcing to invoicing. The batch offers a roadmap for investors and a list of emerging acquisition targets in the evolving AI landscape.
