Your Role

You actively manage our existing customer accounts and act as their primary point of contact across the entire customer lifecycle. Your focus is on continuously increasing the value our AI phone assistant delivers, expanding use cases, and identifying additional potential.

You regularly run review, discovery, and upsell conversations with existing customers, analyse their usage, and demonstrate how our AI can automate further processes and deliver measurable impact.

You own expansion revenue within your customer portfolio — from upgrades and add-ons to renewals — working towards clear monthly and quarterly quotas.

Alongside the commercial side, you carry a strong customer success component: you ensure customers are successfully onboarded, use the product optimally, and stay satisfied long-term. You bring market feedback back into the team in a structured way.

You work closely with Customer Success, Product, and Marketing, ensuring clean handovers, reliable forecasts, and a well-maintained pipeline in the CRM.
