In old-economy-speak what you just said basically translates as "you entered a crowded market".
When you're standing on an unknown, rainy street corner far away from home, a taxi's services are urgently required, and not abundant. When you're lounging on your sofa and start contemplating how it would be nice for someone else to bin the pizza boxes, it's the opposite on both counts.
Moreover, I don't see the money men being impressed by a founder who can put out a piece so toe-curlingly embarrassing as "Dear Future HomeJoy Engineer".
