Sphere, Inc. is developing what it describes as the world's first AI-native tax compliance platform, designed to help businesses navigate the complexities of global indirect tax regulations. The company's core technical work spans artificial intelligence, tax compliance automation, and the codification of global tax law - areas where precision and scale are paramount.
The company's flagship product, the Tax Review and Assessment Model (TRAM), combines a proprietary AI model with human expertise to collect, codify, and monitor tax laws across more than 100 jurisdictions. Notably, the platform can be implemented in under 24 hours, a significant operational advantage in a domain where compliance timelines are often measured in weeks or months.
Sphere has raised $21 million in a Series A round and counts Y Combinator, Andreessen Horowitz, Felicis Ventures, and 20VC among its backers. The company operates within the intersection of tax compliance, international billing, and cross-border regulatory frameworks, and provides 24/7 expert support to its clients.
