Mattia Ciuni

Founder & CEO at Noesia

Milan, Italy–:–:–

I'm building the money layer for AI agents at Noesia. AI agents can already research, compare and execute entire tasks. Then they stop and ask you for a credit card. Noesia gives each agent a wallet with rules: per-agent budgets, merchant allowlists, a deterministic authorization engine, and a verifiable receipt for every transaction.

Before this I built Celeste, an AI browser, and watched users finish the hard part of a task, then abandon it at the payment step. That observation became Noesia. We're applying to YC and relocating to San Francisco.

I ship code under strict acceptance tests and hire on artifacts, not titles. Reach me at [email protected] or on @mattiaciuni, GitHub and LinkedIn, Instagram, YouTube, the Spotify podcast and Crunchbase.

Principles

Build the hard part first.
Everyone ships the demo; the money path is where products die. I start where the risk lives.
Verification over vibes.
If a claim can't survive an audit, a test, or a skeptical engineer, it doesn't go on the internet. Including this site.
Small teams, heavy leverage.
AI tools multiplied my output; discipline multiplied the AI. Two people with tests beat ten with meetings.
The best ideas survive attack.
I post my architecture before I have a pitch. What survives the comments is what gets built.
