Make AI’s financial output verifiable. Make every check auditable.
AI is answering financial questions faster than anyone is checking the answers. Models quote filings and summarize earnings inside products used for real money decisions, and almost nobody traces that output back to a source. Artizar exists to close that gap.
The founders
Santiago Lozano
Co-founder
Santiago studied financial economics at Columbia and worked on M&A at CEMEX. He brings that markets-and-filings perspective to a product he and his co-founder build together.
Kevin Haddad
Co-founder
Kevin studies at Northeastern. He's done much of the engineering behind Artizar, building the verification engine that turns filings into evidence chains, deterministic verdicts, and a signed, append-only audit log.
Verifiability, not infallibility
No one can promise a model that is always right. We promise something you can hold us to: each claim we can check is checked against the filing, and each check goes on the record. Three commitments make that concrete; beside each is the part of a real sealed record that keeps it.
A verdict is never an opinion.
Tiers come from a versioned rule table applied to structured evidence pulled from the filing. No language model is in the path. The same claim, checked twice against the same filings, returns the same outcome, the same rule, and the same evidence hashes.

primary‑source confirmationpolicy‑v7 The record outlives the run.
Every verification is sealed with a signature, and a commitment to it goes into an append-only public log. Months later you can show exactly what was checked and which rule produced the verdict, even after the model or the prompt has changed.

Evidence ends at a primary source.
Every verdict with evidence traces back through an unbroken provenance chain to the filing itself on EDGAR, down to the XBRL fact and its accession number, not to a paraphrase of it. When there is no such fact, the verdict says so.

Live, and early on purpose
The API is in production, and we are onboarding a small number of design partners, one integration at a time. If you’re putting AI in front of financial decisions, we’d like to talk.
If you invest in or advise companies like ours, or know a team that should be able to prove its AI’s numbers, we would like to hear from you as well.
