| 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.) | B-tier. Still early. Manus is more flexible for less money. | A-tier for data teams. S-tier if you already live in SQL + Python. | S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code. |
