One of the most important metric for a B2B SaaS  is the number of licences per client company. Growing this number not only increases revenues but also makes harder for the company to churn.

Of course, if a user leaves his company, he looses his licence. But if he was a satisfied user of the product, it can be a great opportunity to turn him into an ambassador of the product in his next company.

You can use tools like SifData or UserGems to identify when a user changes job. All you need to do then is to offer them an incentive to advocate for your product.

Spendesk, a spend management solution, is a great example of how to implement this method. They identified all the users who left their company after making at least 20 payments using Spendesk and sent them virtual credit cards with $5 so they could buy their CFO a coffee and pitch them the product.
