I would agree but not with $15 in 2 years....more like $30+....we are in an infancy stage in 2013 in the mobile marketing sector. That is the most promising sector and what Velti and Augme dominate as a niche.
I doubt co will be able to stay independent given low attractive valuation. Private equity vultures and likes of Google, Yahoo, Facebook would love to grab this one under $250 mln. But realistic i say buyout more likely between $5 - $10 or 2x sales ($500 mln) but if it management + investors reject any acquisition offers and manage to stay independent then yes may be even $20 in 2 yrs not outta question.
