Yeah, that was my thought. Take a look at enterprise software company multiples. Look at CRM at 8.86 P/S and not profitable, ORCL at 4.55 P/S. Look at Castlight debuting its IPO at 300x sales.
And here is JGPK with a .29 P/S and a P/E under 20, with extremely high growth? Any way you set a target, it's going to be low. But I feel like $1.15 is too conservative, if you are at all bullish.
I'll probably take some profit in the mid $1s, but another large customer would make this a $100 million company IMO.
