Technical intuition

In addition to demonstrating reliance and resourcefulness, successful founders of technology companies typically have good technical intuition. In other words, they know what kinds of technology need to be developed, even if they don't know how to develop it themselves.

This is different from being skilled at implementing new technologies. In fact, many people who know a lot about implementation get too excited by technical challenges and lose sight of whether what they're making is actually useful.

Many of these people also have good intuition about whether technologies should be developed in-house or whether they should be out-sourced. It's important to remember that technologies developed in-house will also need to be maintained in-house. So, if a technology isn't part of a company's core competency, it's likely economical to outsource it, even if that decision is more expensive in the short-run.
