Job description
**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: * We're growing rapidly (34%+ MoM revenue growth) and helping the fastest growing tech companies around the world including Eleven Labs, Replit, Windsurf, Fathom, Linktree, Photoroom, Sierra AI, Zed etc * We’ve spent the last 1.5 years building local rails into tax authorities in both the US and internationally to properly automate compliance processes (no other vendor has done this) * We're building the world's first AI-native tax engine (which will be the foundation for a broader cross border compliance platform; think Deel for international billing) * We're well funded by Felicis Ventures and YC Sphere is looking for a Founding Account Executive to work closely with the Founder (who has been doing founder-led sales to date) to help target mid-market US-based companies selling globally. **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. **What you will do:** * Full-cycle sales: run outbound, close new logos, and expand existing accounts. * Flex across segments: high-velocity SMB cycles and complex mid-market sales. * Build GTM playbooks, assets, and revops stack with the Founder. * Help shape and scale our global sales team. **What’s important to us:** * Hunter: Grit > pedigree. * Fast shipper: If it can be done today, do it today. * Self-starter: No hand-holding * Experience in a quota-carrying role with a track record of exceeding sales targets. * In-person: SF only. **Requirements:** * Proven experience selling B2B SaaS into SMB and mid-market segments. * Early-stage startup experience (building processes from scratch). _Nice to have:_ * Experience selling to the CFO / Finance roles
