Teller, Penn & Teller once said:
"Sometimes magic is just someone spending more time on something than anyone else might reasonably expect."
The same could be said of both startups and software.
Getting software to the point where your audience can immediately connect with it takes a lot more time than one would expect. Startups, like software, require tremendous effort -- much of of is invisible to average person. Like magicians, it takes founders and product developers many years of slogging it out, worrying about every little detail, to make the final product look effortless.
