Fiscal infrastructure is the next category.

Every country is mandating real-time e-invoicing. Every enterprise is bolting it onto Postgres. We are building the engine that makes that obsolete.

Market

A global regulatory wave, on a fixed timeline

E-invoicing mandates are not speculative demand — they are legislated deadlines. Each new jurisdiction expands the addressable market and the value of a multi-jurisdiction connector library.

Thesis

Why now, and why it's defensible

Regulatory inevitability creates the demand. Storage being bolted on, not native, creates the opening.

Closed-source engine

The WAL format, hash-chain construction, TSA pipeline, and connector certification toolchain are proprietary. Customers receive signed binaries and license keys, not source. This is a defensible IP position from day one, consistent with how other infrastructure categories (Snowflake, Databricks, MongoDB Atlas at inception) were built.

Engine-level guarantees

Append-only storage + hash chain + qualified timestamping are extremely hard to retrofit onto a generic database. The guarantee lives below the application, where it cannot be bypassed.

Zero-migration adoption

Wire-protocol compatibility with PostgreSQL and MySQL means no driver changes. Classic Trojan-horse adoption: teams point an existing app at FiscalDB and keep shipping.

Compounding connector library

Each jurisdiction is an independent crate behind one trait. The library compounds in value as mandates multiply — and switching cost rises with every country a customer turns on.

Pure Rust, deterministic

Zero unsafe in critical paths, deterministic recovery, reproducible benchmarks. Infrastructure buyers trust predictability — it shortens the enterprise sales cycle.
