It is a bit tiresome, I get the feeling that they are not talking to me however. I imagine they are talking to someone who's job is to get business software approved by the procurement department. A scenario I know nothing about.
I also imagine some companies do far too much across too broad a spectrum to concisely summarise it. IBM can afford to have lofty aspirational corporate speak because they offer such a wide range of business services to such large entities that you probably need to send your guy to speak with their guy anyway.
My favourite kind of product landing page is a one sentence description of what it does, and below that is a link to the documentation. That makes me think that not only does it do what it says it does, I can probably figure out if it will work for me by reading the docs.
Consumers are not dumb. We see through all the marketing-speak and see your product for what it is.
If its a good product at a good price that ALSO attempts to make a market better - I'm in. Otherwise, spend less on marketing and more on making a better product.
If you really want to "Disrupt" or create a "movement", get into the non-profit sector. At least then we (as consumers) know you aren't full of bullshit.
Also, it seems incredibly desperate and fake when a company tries to forcefully come up with unique culture when there is none to begin with. Some companies are naturally more interesting than others and that's okay. Not everyone can be basecamp and not everyone needs to :)
