People ask me where the name came from fairly often, so here's the answer.
Honestly, the name took a while. I thought about it for over a month and finally landed on Spadeberry one night at around 4am.
The rules a name had to pass
The hard part was the constraints. An intellectual property attorney had explained what I needed: the name couldn't describe what the product does, or I wouldn't be able to protect it. Beyond that, I wanted something that was ideally a combination of two words, that nobody else had used, and that was easy to remember, pronounce and spell. That rules out an awful lot of ideas.
Why "spade"
I learned to play poker from my grandparents when I was a kid, using pennies and nickels for chips. I've loved cards ever since, so I suspect that's what pulled me toward it out of all the variations I tried. But the real deciding factor was simply that Spadeberry fit every one of those guidelines and hadn't been taken.
The logo
The logo came from the same place, really. I thought it looked simple and cool, and I liked that the name and the logo were both simple enough that you could probably guess the name of the company just from looking at it.
