Mission:
Sphere has built the world’s first AI-native tax engine that helps companies like Eleven Labs, Replit, Runway AI, Windsurf (+ many more) automate their sales tax, VAT and GST obligations:
A crucial part of Sphere’s platform involves integrating with customer billing systems (e.g. Stripe, Chargebee, Rillet, Campfire and many more) and ingesting large volumes of transaction data across customers around the world.
As we scale, the need for a uniform data pipeline across these integrations is mission critical and will allow us to service more customers in different industries, with different billing systems and processes.
Why this is a massive opportunity:
🌍 Massive TAM: 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.
🔮 Product vision: Indirect tax is just the start; we’re building the Deel for international billing.
