Frequently asked questions

Start with current MRR, add new customers times ARPU, subtract churn, then add expansion. Compounding those monthly gives the 12-month ARR.
1-2% monthly for SMB, under 1% for enterprise. Above 3% monthly, growth needs very heavy acquisition to stand still.
Net revenue retention. Above 100% means existing customers grow the business without any new sales.
