Unfortunately, without additional context, it is challenging to provide a specific answer because the role of CSM can vary significantly across different companies and industries. Generally, a Customer Success Manager is responsible for building relationships with customers, ensuring their success with the product or service, and ultimately helping to achieve customer retention and growth.
