For EU/AU, it seems to me like you want to be competing with the Nespresso market and leveraging the fact that you can produce a similar 'pod' quality (or better) without the machine - basically a convenience approach, perhaps with some price influence. You'll struggle to compete with superior flavour since we understand decent espresso. There's a reason Starbucks has nearly completely collapsed in Australia and it's largely thanks to Italian migrants in the 60s, and enough of Europe knows about Italy that they have a clue about coffee. The secondary advantage is that in AU at least (maybe also EU? my experience of travel there isn't broad enough), a good cafe-made espresso is quite expensive (AUD$5) so you have profit margins on your side too.
For the US, you can't really compete on price and people are more happy to drink rubbish coffee like badly made drip and Starbucks. To this end, in my mind you will need to convince them that the superior flavour is worth it when it is not prohibited by superior expense or effort (ie: going out to a specialist cafe). The evidence is in this thread where people balk at the idea of a $3 'instant' coffee. This is a distinctly different marketing ploy to the above, but I think a one-size-fits-all won't work for you.
I don't really have a lot to add, but that's my gut feel on how you need to go about pitching this. Simply saying 'we can do instant coffee that doesn't suck!' to me doesn't quite capture the subtlties of the problem you're actually solving for consumers, as it doesn't place it in the broader context of how/where/why they consume coffee.
Good luck!
