Episode notes
AI Agents Can Now Open Real Bank Accounts
- Meow launched the first fintech product that allows AI agents to open real business bank accounts.
- Brandon says this is analogous to mobile banking's early days and positions agentic onboarding as a structural shift in finance.
Engineers Shift From Coding To Reviewing AI Code
- The AI stack leapfrogged quickly and changed development workflows from writing code to reviewing AI-generated code.
- Brandon reports engineers now use agents to triage alerts, submit PRs, and focus on review rather than hand-coding.

- Configure agent accounts with fine-grained permissions and human-in-the-loop checks for large transactions.
- Brandon recommends treating humans initially as a safety harness while agents handle routine banking and scheduling tasks.
