Develop and nurture strong customer relationships throughout evaluation, validation, and purchasing, serving as a trusted technical partner as customers move into production.
Foster customer advocacy and represent the voice of the customer internally by gathering feedback, identifying patterns across accounts, and collaborating with product and engineering teams to inform roadmap and feature prioritization.
Serve as the first line of defense for security, privacy, and compliance questions by explaining Fastino’s standardized materials, guiding customers to relevant documentation, and escalating complex requirements to internal teams as needed.
