There’s some really good advice for job seekers in Carilu Dietrich’s post 10 Most Important Metrics For Evaluating a Company:

Net Dollar Retention (NDR) is one of the best ways to see if a tech company is healthy and growing. It measures the expansion or contraction of a company’s existing customer revenue over a given period. NDR takes into account the revenue lost from churn and increased revenue from upselling, cross-selling, and renewals from existing cusomers.

I would also add Gross Revenue Retention to that list. It describes how much revenue a company keeps from its existing customers over a specific period, not including any new revenue from new customers. So, if a company started the year with $100 from its existing customers and ended the year with $90, even if they lost some customers but upsold others, the gross revenue retention would be 90%. It helps guage how good a company is at keeping its current customers happy and continuing to spend money, without taking into account any new business they’ve gained.
