Why this is a massive opportunity:
We're using AI to codify the world's international trade law. Every business around the world needs this. Compliance isn’t optional. Strong macro tailwinds: Businesses are expanding globally at a faster pace, while tax authorities are cracking down on cross-border compliance, driving urgent demand. AI advantage: Incumbents can’t scale beyond the U.S.; our AI-native tax engine can. Multi product play: Indirect tax is just the start; we’re building a compound startup that helps business with all forms of revenue-based compliance.
