Your bank uses AI to evaluate you.
Use AI to defend yourself.

Artificial Intelligence shouldn't be the exclusive privilege of high finance. We deploy AI agents that read your bank contracts and track the money your suppliers are taking from you in silence.

As a former investment banker and CFO, I know both sides of the window. We automate the audit of your fees, the detection of unfair clauses, and the structuring of your financing requests to rebalance the power dynamics.

SMEs without a CFO
94%

navigate their banking relationships without structured financial expertise

Unfair clauses detected
1/3

of small business bank contracts contain an undisclosed unfavorable clause

Identified hidden fees
100%

of AI audits reveal silent supplier or banking overcharges

The Past · 2008

The Opacity Crisis.

During the subprime crisis, large institutions used complex models to structure opaque products. "Main Street" (the real economy) paid the price. Our mission was born from this battle for financial protection.

"While the arsonists escaped in private jets, the communities inhaled the smoke."
The Present · 2026

AI Against the Silence.

Today, asymmetry persists: banks and insurers use AI to optimize their margins on your accounts. We turn this technology around. We put the power of AI at the exclusive service of SMEs to decode what you sign.

Our Commitment

Zero Conflict of Interest.

We are not brokers. We receive no bank commissions or kickbacks. Our only clients: you. AI allows us to complete in 24 hours the audit work a traditional firm would charge weeks for.
