| Kai's verdict | Stripe Link is the most credible first move toward a real agentic payment layer — the one-time-use card model is genuinely clever, and the existing merchant network gives it a head start no startup wallet can match. But the 'approve every transaction' UX will get old fast, and the hard part (autonomous spending with guardrails) is still on the roadmap. (Verdict pending Phi's full review.) | A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google. | A-tier for data teams. S-tier if you already live in SQL + Python. | A-tier. The most interesting spreadsheet in years. Great for ops dashboards. |
