Sphere

Software became global. Compliance stayed local. Sphere is the AI-native cross-border compliance platform that automates revenue-based tax obligations across 100+ jurisdictions, from registration through calculation, filing, and remittance. At the core is TRAM, a proprietary tax engine trained on real tax code rather than bolted onto legacy tax logic.

Companies like Deel, Runway, HeyGen, Linktree, and ElevenLabs use Sphere to expand internationally without building out compliance teams, live on their existing billing stack in under 24 hours. Backed by a $21M Series A led by a16z, Sphere is working toward one measure of success: the compliance cost of every transaction should be zero.
