The f could presumably be confused with a ph when telling it to someone. Otherwise, it's simple enough so I'd have thought it'd be at least easy to remember. But if you've had a couple of problems then it might be worth exploring other options.
It's true we don't fund single founder startups but we're still interested to see exceptional applications even if it's just one person behind them. You can still get past the first stages of our screening process provided you have an appropriate idea and adequate experience. However, to successfully complete the entire process you need to have found a co-founder by the time this period (~1.5 months) ends. This is not the best case scenario but for exceptional ideas we're willing to consider it.
