The web is like a jungle, it grows fast, it changes fast and everything is fragile - it may never forget, but its memory starts to crumble and fade very quickly. Content loses context, pages fall apart, data and services vanish. Create fossiles of your websites and your content - even single page applications, to persist a consistent representation of your page for potentially many decades in formats most likely supported for another 100 years.
For Managers: Keep track of any public content - without having to ask IT.
For Investors: Keep a history of companies content you invest in.
For Marketeers: Keep track of your companies public content independent of IT or design changes.
For Sales: Monitor and search your marked over time including changes.
For Legal: Prove what content was available on which site at which time.
