After spending 5 seconds reading I can't tell what your mission is. It works best to first write out the mission statement in a one sentence.
Do you sell photovoltaics? Jewlery? Bitcoin services? My mind jumps around with the current page.
The mission statement may also read better if it talks about what the company wants to do -- not what the visitor wants.
