Help shape the brakes for AI agents that move money.

We're looking for our first two or three design partners.

Is this you?

What you get

Now
A live walkthrough of the working product with your own example: your amounts, your limits, your approval flow.
Your workspace
Your own hosted test workspace at app.getonbehalf.com, for your agent and your team.
Always
A direct line to the founder. What you need shapes what we build next.
For your reviewers
Receipts they can check themselves, without trusting us or you.
What you can test today
Paying suppliers in USDC on Base; refunds, charges and account credits in your own Stripe test account. Tell us which payment your agent makes first, and we test that one together.
Pricing
We'll set prices together with our first design partners.

What we ask

The terms

How long
Up to 4 weeks. Most partners finish sooner.

Free during the program.
After
Stay on, and you get a founding-partner discount for your first year. We'll set the amount together.
Privacy
A mutual NDA, if you want one.
Your name
We never name a design partner in public without written permission.

A note from the founder

Onbehalf started with a mistake. I was building on an AI platform, paying for credits myself. An agent did something I never approved and kept burning them. I got refunded only because I noticed and pushed. On your own money, every dollar counts. So I'm building what I wished I'd had: a yes before the money moves, and a receipt after.
