Founding Account Executive

About Sphere

Sphere is using AI to codify the world’s international trade law.

We help some of the fastest-growing tech companies:
Lovable, Eleven Labs, Replit, Runway AI, Windsurf, Deel, Linktree, and more, 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 (think Deel, but for everything tied to revenue).

We’re growing fast (30%+ MoM revenue growth) and are backed by a16z, YC, 20VC, and Felicis Ventures.

Sphere has reached the point where founder-led sales no longer scales. This role exists to own and professionalize revenue, without slowing the company down.

As a Founding Account Executive, you’ll work directly with the Founder to take what’s working, sharpen it, and turn it into a repeatable GTM engine. You won’t inherit a polished playbook. You’ll help build it, while closing deals at the same time.

This is a true founding sales role with real influence over motion, messaging, and how the team scales.

• Massive 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 start—we’re building a compound company around revenue-based compliance.

You’ll operate as a high-agency, full-cycle seller with founder-level exposure.

You will:

• Run full-cycle sales: outbound, close new logos, and expand existing accounts

• Flex between high-velocity SMB deals and more complex mid-market sales

• Partner directly with the Founder to build GTM playbooks, sales assets, and the revops stack

• Pressure-test messaging, ICPs, and channels through real deals

• Help shape the structure and hiring plan for the future sales team

• Represent Sphere with credibility to finance leaders and operators navigating global compliance

This role is for hunters who like responsibility and speed. Pedigree matters less than output.

You likely:

• Thrive in zero-to-one environments

• Don’t wait for instructions—if something can be done today, you do it today

• Enjoy building process while carrying quota

• Are energized by selling mission-critical infrastructure, not “nice-to-have” tools

• Want to be early and have your fingerprints on how revenue is built

• Proven experience selling B2B SaaS into SMB and mid-market customers

• Track record of exceeding quota in a quota-carrying role

• Experience in early-stage startups, building process from scratch

• Strong outbound skills and comfort owning the full sales cycle

• Ability to work in-person in San Francisco

• Experience selling to CFOs, finance, or accounting leaders

• Background selling compliance, fintech, or infrastructure software
