Three big business problems with two commonalities. Can you name them?

Company #1: found a reporting solution that fit all of their criteria, over and above the usual players.

Company #2: created a series of wireless applications to allow their floor workers to quickly gain access to the information they needed from their blackberries.

Company #3: built a custom shopping cart application, like this one that was actually less expensive (and took less time to implement) than the packaged solutions they were considering.

So? What do these three have in common?
