Frequently Asked Questions

Why use a dedicated CS platform instead of a legal CRM?

While CRMs track the sales pipeline and contact info, CS platforms focus on the post-signature experience, using data to predict which clients are likely to leave or expand their relationship.

Is Gainsight too complex for a mid-sized law firm?

Most AI platforms suggest yes. Unless you have over 500 employees or a dedicated operations team, the complexity of Gainsight may outweigh its benefits compared to more agile tools like Vitally.
