An independent studio for financial software.

The studio

We are a founder-led studio. The work combines finance, artificial intelligence, automation and software, and it starts from the business problem.

Banzinni Lab does not provide regulated financial services or investment advice. Systems described on the homepage are private and internal. They have no public demo.

How the studio works

1. 01

   Business first. The problem comes from financial operations. The software is built to fit that problem.

2. 02

   Models as a team. Claude, GPT, Gemini, Grok and local models each have a role. One builds, another reviews, another audits, with cross-review. This is in daily use, and it is internal.

3. 03

   Checked before it ships. Security is reviewed first. Test stays separate from production. Outputs can be audited, including spreadsheets that show their formulas.

4. 04

   Private when it is private. What we have built stays internal unless a public version exists. None of the systems on the homepage has a public demo.
