About

Sphere is an AI-powered cross-border compliance platform.

We help companies like Lovable, Eleven Labs, Replit and Windsurf automate their sales tax, VAT, GST compliance obligations.

What makes us different to other vendors on the market is:

1. we have spent the last 1.5 years building local rails into 100+ tax authorities in both the US and internationally to properly automate compliance processes, and 2. we've built the world's first AI-native tax engine which ingests, codifies and monitors tax law globally.
