Background

About Jonas Wren

Jonas works two days a week inside client companies as their finance lead: cash flow, pricing, credit control and the numbers the owner needs every Monday.

He has been the first finance hire at three growing companies, so he knows when a company is ready to hire its own.

Most of his engagements end with him helping to recruit his replacement. Demo profile: the person and details are invented.
