- Founders now use AI agent AI software that takes actions on its own, like booking, buying or moving money, not just answering questions. for almost every job, from code and company filings to marketing videos. A Helsinki pair has an agent running the build of their next automated biotech lab, from buying kit to directing contractors.
- Founders date the shift to late-2025 coding tools such as Anthropic's Claude Opus 4.5 and Claude Code. One New York founder says a recorded customer call can become a working prototype two days later. Weekly US business applications have mostly stayed above 100,000 since ChatGPT launched, Apollo data show.
