Every transaction is a claim about reality.
We make claims verifiable.
Tax returns, property closings, compliance filings. The rules are written. The answers are deterministic. Our software proves it.
Products
Four platforms.
One architecture.
Veritas
Tax computation that shows its work. Every number links to the IRC section that authorizes it. Multi-state returns in under a second, online or off.
TerraOS
Search a property, finance it, close it, stay compliant, tokenize it. One platform handles the whole deal.
Insights
Energy-aware cloud intelligence. Every API call tracks consumption, calculates emissions, and proves regulatory compliance in real time.
TradingOS
Matching engine, pre-trade risk, settlement, and surveillance infrastructure for licensed trading venues, exchanges, and broker-dealers.
Technology
Built different. On purpose.
These choices were made before we wrote the first line of product code. You can't retrofit them. We didn't have to.
Rust Everywhere
One language runs the tax engine, the frontend, and the geospatial stack. Memory-safe. No garbage collector. Fast.
Formal Verification
We prove the math is right. Kani symbolic execution and 225K Monte Carlo scenarios. Every computed value traces back to its legal citation.
Offline-First WASM
The full engine compiles to WebAssembly and runs in your browser. Works without internet. Syncs when you're back online.
Multi-Model Database
JouleDB handles SQL, graph, vector, time-series, and OLAP in one engine. One database instead of five.
Financial Precision
Money stored as i64 cents. Rates stored as basis points. No floating-point anywhere near a dollar amount. Rounding errors don't exist here.
AI Suggests, Math Decides
LLMs classify documents and surface recommendations. The tax engine and compliance layer make the final call. No black-box financial decisions.

}Thesis
The science of transactions.
A transaction is a claim about state. A manifest says 14 apples. A tax return claims $47,000 in deductions. A deed transfers 2.3 acres. The question is always the same: does the claim match reality?
We verify everything we compute.
Every financial transaction is a deterministic function. The inputs are known. The rules are published. The output is computable. There is a correct answer, and it's already written in the law. The gap between what software claims and what the law requires is the verification gap. We close it.
R Regulatory Tailwinds
AML/KYC reporting is now mandatory for all-cash real estate transfers. TerraOS already handles it.
Tokenized real estate now has clear rules. TerraOS supports SEC Reg D/A+ and EU MiCA.
Major tax code changes hitting every US taxpayer. Veritas models both scenarios and shows the IRC math behind each one.
Crypto-asset regulation across the EU. Our systems handle multi-jurisdiction compliance out of the box.
D What We Deliver
Every value in a Veritas return links to the IRC section that authorizes it. The claim is the return. The proof is the citation.
TerraOS tracks the full lifecycle: search, finance, close, comply, file. One system holds the state. One system verifies it.
Insights measures the energy cost of every computation and generates verifiable CSRD and MiCA compliance reports.
A tax return is a pure function. A closing is a state machine. A compliance check is a predicate. We treat them that way.
