Wix website for a software company. Design & commercial writing (Eng)

We created a new Wix website for a new software called “Agile Planning”. The software is a financial planning solution for enterprise (you can see other players in these markets like www.anaplan.com , www.jedox.com https://www.wolterskluwer.com/en/solutions/cch-tagetik or www.qlik.com\us as an example).
We need help shaping it to a professional look & feel and refine commercial writing (English).
