ExamPower.com – nice brandable that would be a great fit for a startup in the education-space focused on tests/exams. I could see this become home to a new competitor to someone like Kaplan or Princeton Review.
OneCharge.com – I really like this one, seems like a particularly good option for a startup that does something in the mobile charging space. Given that just about everyone has a smartphone, and smartphones are constantly running out of juice, the charging space is hotter than it has ever been.
Development.io – if you’re a startup that build developer tools or creates tutorial for developers this one is easy to remember and the .IO makes perfect sense here.
eStocks.com – for startups in the stock-trading space this one seems like a slam dunk, I would just also recommend getting eStock.com as well so you can own the pair and avoid confusion.
Agenda.com – solid choice for a startup in the calendar/planning space, get organized with Agenda.com, I can see it already
