Your spending agent.
Governed by your policies.
Vesper lives in your dashboard, spends on your behalf, and asks permission when it should. Every action gated by the limits you set — daily caps, single-transaction maxes, blocked categories. Bring external agents too; the same rules apply to all of them.

Vesper lives in your dashboard from day one. Set your limits, connect a payment method, and Vesper transacts on your behalf within the guardrails you control. External agents (Claude, GPT, Devin) plug into the same engine.
Meet Vesper
Vesper is already in your dashboard. Set spending limits, blocked categories, and approval thresholds — your policy, your defaults.
Authorize & Evaluate
Every spend intent runs through Greene before any money moves. Identity, policy, and counterparty trust evaluated in under 50ms.
Execute & Audit
Approved decisions return a signed token for your payment rail. Held requests trigger instant Slack or email notifications.
What happens without a control plane.
If your agent spends money and something goes wrong, can you prove a human was in the loop? Most teams can't.
Rogue spend loops
One bad prompt and an agent burns through a Stripe budget in minutes. By the time your alert fires, the damage is done.
Unknown actions
Agents transacting without a verified identity behind them. Who is responsible for the spend? Without Greene, nobody knows.
Compliance gaps
When regulators or auditors ask for proof of approval for an autonomous action, terminal logs won't satisfy them.
Watch the controls
do their job.
Every authorization, every denial, every human-approved request — streamed in real-time and pinned in an immutable audit log for compliance.
