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.

No investor is drawn from a Form D — the form states how many invested and never who. The one investor on this graph is named because a batch has exactly one.

If you're behind Sphere: acceptance into a YC batch is one of the few weeks a young company gets looked up by people who matter — investors, other founders, press. FoxPlug turns the commits, deploys, and releases you're already making into that story automatically, so anyone who looks finds something current. GetFoxChat puts a guide on your own site so the people YC's own page just sent you don't read one line and leave.
