Adi Singh is the co-founder of AgentMail (YC S25), the first email provider built for AI agents instead of humans, backed by a $6M seed led by General Catalyst. Before AgentMail, he worked in venture at Accel — until a failed get-rich-quick scheme revealed the missing primitive of the agent economy: identity. His customers went from asking for one inbox to asking for a million, and his claim is simple: you'll never have to receive an email again.
We discuss:
1. Why agents need identity before they need more intelligence — and why email is the wedge
2. The failed Shopify automation scheme that accidentally became AgentMail
3. "We don't want one inbox. We want a million" — the customer request that changed the company
4. People are buying SaaS seats for their agents, and why software gets richer, not poorer
5. How Adi's Codex agent runs his email — and his dinner reservations
6. Credit scores, insurance, and bank accounts for AI agents: the internet rebuilt for its new citizens
7. The one-person $100B company, and why humans stay at the center
8. AgentMail's hiring rule: spikes, not gap-fillers
