About This Role

As a Customer Success Associate for AgentPro, Goodstack's AI-powered grant writing platform, you will own the end-to-end customer journey for nonprofit and corporate clients.

Later, you could analyze usage data to identify upsell opportunities, collaborate with the product team on feedback, and end with a renewal conversation. Every day is a mix of strategic and tactical work to ensure clients achieve their funding goals.
