Customer Support Lead

About Mantle

We're building an AI agent to help families support their aging parents (origin story here).

Over 40M "sandwich generation" Americans currently manage their parent's affairs. Keeping mom/dad safe and supported is like a second job: it's time-consuming, stressful and on top of their already busy lives. We believe that managing our parents' affairs should feel under control, easier and lower stress.

Co-founded by serial entrepreneur partners including Ted Zagat, who sold his previous businesses to Slack (announcement here) and Google (Zagat restaurant guides).

The Role

We are looking for a Customer Support Lead to be the voice of Mantle for the families we serve. Behind every family is a real situation, and when they reach out, they need someone who is fast, warm and genuinely helpful. You will work side-by-side with the founders, product and engineering to make sure every family gets real results, and turn what you learn into a better product.

This is a role for a builder. In the early days, you'll be answering tickets, onboarding families and handling tricky situations yourself. It's not just about support; it's about the unglamorous work of documenting every issue, writing the playbooks, and spotting the patterns that let us fix problems at the source. You'll be the one doing the manual work today so we can build the support systems, and the AI, of tomorrow.

What You'll Build

• Support function: Stand up the tools, processes and service standards for supporting Mantle's families.
• Family onboarding: Help new families get set up and get value from Mantle quickly.
• Help center and playbooks: Create the documentation that answers common questions and guides how we handle complex ones.
• AI partnership: Review and improve how our AI agent handles conversations, and define when a human needs to step in.
• Voice of the customer: Bring what families need back into our product and roadmap.
• Support analytics: Track response times, satisfaction and top issues, and drive them in the right direction.
