Second, to lead, mentor and coach an ethical, culturally aware, financial team which has a strong business partnering mind-set and is driven by desire for innovation and continuous improvement.  The Five9 Finance function is deeply respected within the company for its service orientation, for the accuracy and timeliness of operational and financial metrics and for the quality of its analyses.

And third, to meet the needs of the investor community who have a vital interest in understanding Five9’s strategy and prospects.   By executing its growth and margin expansion strategy and by providing clear and transparent communications, Five9 has cultivated institutional ownership by premiere mutual funds and other leading investors and seen its stock price increase by more than 600% since its IPO five years ago.
