Full 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
