Yea, go for something symbolic and memorable, a word is not likely to attract someone’s attention or become synonymous with your business, whereas a symbol might.
I’d suggest drawing up a spider diagram with a list of word associations from what springs to mind when you think about what your company represents, and then seeing which of those ideas would be developable. 
Good luck, I’m sure you’ll come up with a good logo!
EDIT: I was thinking about this. Perhaps, a disc with flames in some way? Just to see how it would work out, it would fit with software, or perhaps you could do something with a webpage and flames?
Although, even though all of the suggestions in this thread are to use fire in some way. Perhaps trying a different approach would be beneficial? After all, the worst that can happen is that you have to scrap it.
