Building in the open · 2026

Indirect tax infrastructure for global operations

Tax determination, compliance workflows, and audit-grade traceability across jurisdictions. Built for finance and tax teams that need to defend every number.

What's inside

The bones of a tax operating system

⚖️

Multi-jurisdiction determination

Country modules for US sales & use tax, UK VAT (MTD-ready), German UStVA, and Indian GST — with the right rates, exemptions, and reverse-charge logic built in.

🔗

Audit-grade traceability

Every tax determination links back to the source transaction, the rule applied, and the system action that produced it. No black boxes.

📋

Compliance workflows

Filing generation, GL reconciliation, and anomaly detection — modeled around how real tax teams actually work, not how software vendors wish they did.

🔌

API-first

Clean REST surface designed for finance stacks. Integrate with your ERP, billing, and GL — and build on top of the same primitives we use internally.

We're working with a small group of early partners while the platform hardens. If you operate across multiple jurisdictions and the audit trail matters, we'd like to talk.
