About your last point, could you give me a little more information on this? I already stated that I noticed X problem from running my other business. Anything else I could put in there to maybe build some trust for those who might be a little uncertain of dealing with a business in another country?
Instead of having an about page why not just remove it and make your contact page a little more personal than just an email link?
After looking over it I really dont think the about page is really going to offer much value to your service. But a more personal contact page would be where I would spend the time. On the contact page explain that saasymetrics is a startup and that you are trying to solve X problem and you encourage people to get in contact with you.
