Founding Account Executive

Founding Account ExecutiveSphere is using AI to codify the world's international trade law. We help some of the fastest-growing tech companies automate sales tax, VAT, and GST compliance across borders. Our customers operate globally, move fast, and can't afford compliance to slow them down. Over the last two years, we've built local rails into 100+ tax authorities worldwide, enabling true end-to-end automation that no other vendor has achieved. On top of that, we're building the world's first AI-native tax engine, the foundation for a much broader, global revenue-compliance platform. We're growing fast and are backed by a16z, YC, 20VC, and Felicis Ventures. Why This Role ExistsSphere has reached the point where founder-led sales no longer scales. This role exists to own and professionalize revenue, without slowing the company down.

Why This Is a Massive OpportunityMassive TAM: Every business selling internationally needs this. Compliance isn't optional.Macro tailwinds: Global expansion is accelerating while tax authorities are tightening enforcement.AI advantage: Legacy vendors can't scale globally; our AI-native engine can.Multi-product future: Indirect tax is just the startwe're building a compound company around revenue-based compliance.What You'll OwnYou'll operate as a high-agency, full-cycle seller with founder-level exposure.
