Pleo is a European business spend management solution (think: digital receipts, expenses, invoices). Founded in Copenhagen in 2015, Pleo serves 16 markets across Europe and works with companies from startup to the midmarket. Some quick stats on Pleo:

~€100m ARR and growing 80% year-over-year
Valued at $4.7 billion, making it one of the top SaaS/FinTech startups in Europe
Generates revenue from two sources: a SaaS fee and interchange on card spend
Since inception, Pleo's commercial efforts have been sales-heavy. They've recently turned to a combination of bottom-up PLG and top-down sales plus customer success. Their embrace of PLG has clearly paid dividends for the business – more on that later.
