AI agents are starting to spend.
We're building the controls.
Today, teams hand their agents a shared company card and hope for the best. No per-agent controls. No visibility. No audit trail.
How we build
Clear boundaries earn trust.
01
Trust by default
Provider credentials and signing material stay outside the agent runtime. Custody runs on regulated infrastructure while Reinx keeps policy boundaries explicit and auditable.
02
Developer-first
MCP over HTTP and a conventional REST API make the financial boundary easy to connect without locking builders to one model, framework, or invented SDK.
03
Agents deserve guardrails
AI should have financial autonomy within boundaries humans define — not boundaries the AI negotiates.
The agent economy is already here.
AI agents are becoming autonomous economic actors — and the financial tools to support them don't exist yet.
Agent fleetsTeams are moving from one assistant to many specialized agents.
Real budgetsUseful autonomy requires a safe way to pay.
Clear evidenceEvery payment decision needs context, scope, and an audit trail.
Join us in building
the agent economy.
We're pre-launch and looking for early builders.
