Job description

An early-stage, venture‑backed AI startup is building a next-generation CRM designed from the ground up for the AI era. Rather than relying on manual data entry and rigid workflows, the platform automatically captures customer interactions, organizes context, and surfaces actionable insights to help revenue teams work more effectively. Since launching, the company has seen exceptional early traction with thousands of businesses adopting the product and a rapidly growing base of paying customers.

Backed by some of the world's leading venture capital firms and founded by an experienced 40‑person team with a history of building widely adopted AI products, the company is now entering its next phase of growth. They're looking for their first Customer Success hire to build the post‑sales function from scratch, combining hands‑on customer support with AI‑driven automation to create a highly scalable customer experience.
