AI That Never Lies About Numbers

Verified AI for M&A, Due Diligence & Financial Modeling. Built by a Wall Street veteran who lived the pain of 110-hour weeks.

THE PROBLEM

Excel Is Broken. And It's Breaking Us.

88% of spreadsheets contain errors. Financial professionals spend 20-40 hours/week on manual model building. One mistake can destroy careers and kill deals worth hundreds of millions.

"I lived this reality for over a decade. At Bank of America, I worked up to 110-hour weeks, much of it doing work that machines should do."
Rafael Lage, Founder & CEO

THE SOLUTION

The Netflix of Financial Modeling

Sanity-Checked is a hybrid AI architecture that builds complex, auditable financial models in minutes — with cryptographic proof that every number is correct.

🛡️ Fail-Closed Design
When in doubt, says "I don't know" instead of guessing

🔐 Cryptographic Attestation
Every number has verifiable proof (VFID/PoX/PoC)

📊 Native Excel Output
Delivers .xlsx files — no workflow disruption

🌍 Multi-Standard Support
IFRS, GAAP, local rules via Policy Packs

🧠 Infinite Context™
No token limits. Your entire deal history, all documents, every conversation — always available. The AI never forgets.

🚫 No Hallucination
Unlike generic LLMs that invent numbers, Sanity-Checked only outputs what it can prove. When uncertain, it says "I don't know" — never guesses.

🔌 API-Ready Architecture
Built for enterprise integration from day one. Expand to any workflow — FP&A, compliance, audit, and beyond.

📈 Platform, Not Point Solution
Start with M&A modeling. Expand to budgeting, due diligence, board reporting. One architecture, infinite use cases.

FOUNDER-MARKET FIT

Built By Someone Who Lived Every Angle of This Problem

Rafael Lage spent 14+ years in finance — Bank of America, Private Equity, Venture Capital, Corporate M&A, and Startup CFO. He's sat on every side of the table where Sanity-Checked will be used

✓ Big4 Consultant (EY)
✓ PE Investor (Gulf Capital)
✓ Strategic Buyer (Cogna — R$7.5B LBO)
✓ IB Dealmaker (BofA — $5B+ deals)
✓ VC Investor (Greenfield)
✓ Startup CFO (EVNT — 10x revenue growth)

Recently contracted by a leading AI lab to train their LLM for complex financial modeling — building a better engine for the airplane he's constructing.

"I didn't choose this company. It chose me. Every career decision of the last 14 years prepared me for this moment."

Why Now?

- Microsoft cut Copilot sales targets by 50% (Dec 2025)
- Big Tech won't build this — liability + cannibalization + horizontal focus
- LLMs are commodity engines — we build the airplane
- AI fatigue creates demand for TRUST, not more AI hype
