About the role

You will own the end-to-end sales cycle for enterprise customers across the United Kingdom and European Union, positioning StackOne as the essential integration infrastructure for AI agents.

You are responsible for building and maintaining a robust pipeline that feeds the business with qualified opportunities and predictable revenue. A core part of your remit involves collaborating closely with the US-based leadership team to refine messaging, adjust positioning, and ensure alignment with product strategy.

Ultimately, your success will be measured by your ability to convert interest into committed contracts and expand footprint within strategic accounts.
